How to build a secure mobile wallet for fintech users?

In the dynamic world of digital finance, mobile wallets have become an integral part of daily transactions. From contactless payments to peer-to-peer transfers, mobile wallets are redefining how users interact with money. However, the convenience of mobile wallets also brings heightened security concerns. For companies involved in software development fintech, building a secure mobile wallet is critical to winning user trust and ensuring regulatory compliance. In this article, we’ll explore the key steps and best practices to build a secure mobile wallet for fintech users, using real-world insights from leaders in fintech services like Xettle Technologies.

Understanding the Importance of Security in Mobile Wallets

Mobile wallets store sensitive data such as card numbers, banking information, and personal identification details. A single breach can lead to severe financial loss and reputational damage for both the user and the fintech provider. Therefore, security must be considered from the very beginning of the mobile wallet's design and development.

Key Steps to Building a Secure Mobile Wallet

1. Start with Secure App Architecture

Security begins with the foundation. Develop an architecture that isolates sensitive components and follows the principles of least privilege. Critical elements such as authentication, encryption, and transaction processing should be separated into secure modules.

Choosing a layered security approach, also known as "defense in depth," is a common strategy in software development fintech projects.

2. Implement Strong Authentication Methods

Authentication ensures that only legitimate users access the wallet. Modern mobile wallets must use:

Multi-Factor Authentication (MFA): Combining passwords with biometrics (fingerprint, facial recognition) or OTPs (One-Time Passwords).

Device Binding: Tying the user account to a specific device to prevent unauthorized access.

Behavioral Biometrics: Monitoring patterns such as typing speed or device handling for additional authentication layers.

These authentication methods significantly lower the risk of unauthorized access.

3. Use End-to-End Data Encryption

All sensitive information must be encrypted both at rest and in transit. Implement strong encryption protocols like AES-256 for data storage and TLS 1.3 for data transmission. In addition, sensitive information such as card details should never be stored on the device unless absolutely necessary.

Tokenization — replacing real data with unique identifiers — is another popular strategy in fintech services to protect data from being exposed during transactions.

4. Enable Real-Time Fraud Detection

Mobile wallets should be equipped with real-time fraud monitoring systems. Integrate AI and machine learning algorithms to detect unusual patterns such as:

Multiple login attempts

Transactions from unknown devices or locations

Rapid, repeated transaction requests

Instant alerts and transaction blocking mechanisms help to prevent fraud before it escalates.

5. Stay Compliant with Regulatory Standards

Mobile wallets must comply with financial industry standards and regulations such as:

PCI-DSS (Payment Card Industry Data Security Standard)

GDPR (General Data Protection Regulation)

PSD2 (Payment Services Directive 2)

Meeting compliance requirements not only protects users but also shields the company from legal penalties.

6. Conduct Regular Security Audits and Penetration Testing

Security is not a one-time implementation. Mobile wallets must undergo continuous security audits and third-party penetration tests. Vulnerabilities should be patched quickly, and users must be updated with newer, more secure versions of the app regularly.

Engaging a dedicated security team, either internally or externally, is a common practice among leaders in software development fintech.

7. Educate Users

No matter how secure a mobile wallet is, user behavior can still pose risks. Provide users with best practices for protecting their accounts, such as:

Using strong passwords

Avoiding public Wi-Fi for transactions

Keeping their devices updated

Educational prompts within the app or email campaigns can go a long way toward improving overall security.

Best Practices for Mobile Wallet Security

Minimize Data Storage: Store only what is absolutely necessary.

Use Secure APIs: Ensure all external API integrations follow secure coding standards.

Implement Session Timeouts: Log users out automatically after periods of inactivity.

Adopt Secure Coding Practices: Prevent common vulnerabilities like SQL injection, cross-site scripting (XSS), and insecure data storage.

Top Security Features Every Business Application Should Have

It’s not enough to just provide functionality and usability in today’s digital-first business environment and build really great applications. It has become imperative to keep security at the top of the priority list. All businesses, big or small, are getting caught in the rising tide of cyber-attacks, which threaten everything from daily operations to customer trust and long-term reputation at any given moment.

Application security may be important for every industry-finance, healthcare, e-commerce, logistics, or otherwise. No matter which trade you belong to in terms of being identified as dependent on a digital platform-your application security policy has to be non-negotiable. Simply installing or plugging a few off-the-shelf solutions and hoping for the best is obsolete. Well-structured, proactive security solutions must be integrated the moment the idea is conceived.

In this blog, we will dissect the most important security features every business application must have-what this means for operations, customers, and the bottom line.

Strong Authentication and Access Controls

One of the first lines of defense in any application is verifying who can access it and what they can do once inside. Robust authentication ensures that only authorized users get into them, while access control limits what they can see or manipulate according to their roles.

Modern business applications should incorporate:

Multi-Factor Authentication (MFA) affords the confirmation of users’ identity against passwords, biometrics, and OTP.

Single Sign-On (SSO) allows people to have approved, secure entry to more than one system with a single set of credentials.

Role-Based Access Control (RBAC) minimizes driver threats inside the company by assigning permissions relative to job roles.

Working with a reputable software company gives access to end-user customization and development of access control systems under internal policy and workflow. This ensures that sensitive information remains confidential from unauthorized personnel and has an audit trail of who did what and when.

Comprehensive Data Encryption

Encryption is necessary for securing business as well as individual data. All stored data, whether in a database or transmitted over networks, should be scrambled so that it would not be intelligible to unauthorized parties.

In this case, Encryption at Rest protects the stored data in the hard drives or cloud storage.

Encryption in Transit secures data sent across the internet or internal networks.

Having standards set for data storage, such as AES-256, and data transmission like TLS 1.3 will result in making any data collected during the breach useless to attackers. It protects the organization’s data but also ensures that it abides by related legal frameworks such as GDPR, HIPAA, and CCPA.

Most companies prefer developing customized software in-house so that it becomes easier to manage encryption. Though generic tools can provide a few features, specific software can embed encryption within the individual layers of the application based on how sensitive this particular data environment is structured.

Secure API Integrations

Currently, APIs (Application Program Interfaces) have become very important for any business application to communicate effectively with third-party tools, services, and internal systems. However, unsecured APIs may turn out to be one of the most significant loopholes.

To safeguard the API endpoints, the businesses should have:

Token-based authentication (OAuth2)

Throttling and rate limiting

Validating the inputs

API gateways

It ensures that only authenticated users can perform any operation over the application data and services. These measures would reduce the risks of denial-of-service (DoS) attacks, scraping of data, or unauthorized access to data.

Custom APIs, again, part of custom software solutions, tend to be more secure since they’re built for a purpose and typically don’t leave much room for errors or compatibility problems with other platforms.

Routine Patching and Update Mechanisms

Flaws in software are bound to appear somewhere in its life cycle. However, the extent to which your application reacts fast and effectively to such flaws greatly affects the security posture. Known exploits not patched in time have the potential for catastrophic breaches.

A secure application:

I. Accommodate seamless update mechanisms.

II. Applies patches without downtime.

III. Sends real-time alerts when vulnerabilities are discovered.

That is why, when tied to a professional software development company, businesses can make sure that their applications aren’t merely monitored for hitches but also kept with a current patch level to quickly seal holes from known attack vectors.

Input Validation and Injection Prevention

User input areas for applications — especially those for forms or search boxes — are prone to injection attacks. SQL injection, cross-site scripting (XSS), and command injection can become disastrous attacks by enabling the attacker to manipulate the application to behave in an unintended manner and/or expose sensitive information.

Some fundamental practices include:

Input format validation (e.g., email, phone number)

Input sanitization to remove dangerous characters

Output escaping to inhibit code injection

By building these validations natively into your codebase, you lower dependency on third-party libraries and significantly reduce the risk of compromise for the applications.

One of many good things about custom software solutions is that you can define validation rules based on specific business logic and user flows. Thus, resulting in more secure and reliable applications.

Advanced Logging and Real-Time Monitoring

Security not only views itself as a barrier against disruptive forces but must also tend to detect and respond to them instantaneously. Tools for logging and monitoring can record user activities, detect anomalies, and send alerts based on observed irregularities in behavior.

CNSA 2.0 Algorithms: OpenSSL 3.5’s Q-Safe Group Selection

The CNSA 2.0 Algorithm

To prioritise quantum-safe cryptographic methods, OpenSSL 3.5 improves TLS 1.3 per NSA CNSA 2.0 recommendations. With these changes, servers and clients can prefer Q-safe algorithms during the TLS handshake.

OpenSSL employs unique configuration methods to do this without modifying TLS. For instance, servers use a delimiter to sort algorithms by security level while clients use a prefix to indicate key sharing.

These changes provide backward compatibility and reduce network round trips to enable a smooth transition to post-quantum cryptography while maintaining the “prefer” criterion for Q-safe algorithms. This version of OpenSSL is the first major TLS library to completely implement CNSA 2.0, and its long-term support makes it likely to be widely deployed.

Q Safe

Quantum-Safe Cryptography and Quantum Computer Danger

The possibility that quantum computers may break asymmetric encryption drives this research.

“Future quantum computers will break the asymmetric cryptographic algorithms widely used online.”

To secure internet communication, quantum-safe (Q-safe) cryptographic methods must be used.

CNSA 2.0's NSA Major Initiator mandate

The NSA's Commercial National Security Algorithm Suite 2.0 (CNSA 2.0) lists authorised quantum-safe algorithms and their implementation timetable. TLS allows ML-KEM (FIPS-203) for key agreements and ML-DSA or SPINCS+ for certificates.

The CNSA 2.0 requirement requires systems to “prefer CNSA 2.0 algorithms” during transition and “accept only CNSA 2.0 algorithms” as products develop. This two-phase method aims for a gradual transition.

The TLS “Preference” Implementation Challenge

TLS (RFC 8446) clients and servers can freely pick post quantum cryptography methods without a preference mechanism. The TLS protocol does not need this decision. The TLS standard allows clients and servers wide freedom in choosing encryption techniques.

A way to set up TLS connections to favour CNSA 2.0 algorithms is urgently needed. One must figure out method to favour Q-safe algorithms without modifying the TLS protocol.

OpenSSL v3.5 Improves Configuration Features

Developers focused on increasing OpenSSL's configuration capabilities since altering the TLS standard was not possible. The goal was to let OpenSSL-using programs like cURL, HAproxy, and Nginx use the new preference choices without modifying their code.

Client-Side Solution: Prefix Characters for Preference

Clients can provide Q-safe algorithms in OpenSSL v3.5 by prefixing the algorithm name with a special character (”) before the algorithm name in the colon-separated list. The ClientHello message asks the client to generate and deliver key shares for ML-KEM-1024 and x25519, showing support for four algorithms.

A client can submit a maximum of four key shares, which can be modified using a build option, to minimise network congestion from Q-safe key shares' increased size. This architecture should allow completely Q-safe, hybrid, legacy, and spare algorithms.

For backward compatibility, the first algorithm in the list receives a single key share if no ‘*’ prefix is supplied.

Server-Side Solution: Preference Hierarchy Algorithm Tuples

The server-side technique overcomes TLS's lack of a native “preference” mechanism by declaring the server's preferred algorithm order using tuples delimited by the ‘/’ character in the colon-separated list of algorithms.

The server can pick algorithms using a three-level priority scheme.

Tuple processing from left to right is most important.

Second priority is client-provided key sharing overlap inside a tuple.

Third, overlap within a tuple using client-supported methods without key sharing.

Example: ML-KEM-768 / X25519MLKEM768

Three tuples are defined by x25519 / SecP256r1MLKEM768. Within each tuple, the server prioritises algorithms from previous tuples, then key share availability, and finally general support.

Even with a vintage algorithm with a readily available key share, this solution ensures that the server favours Q-safe algorithms despite the risk of a HelloRetryRequest (HRR) penalty: The prefer requirement of CNSA 2.0 prioritises Q-safe algorithms, even at the risk of a round-trip penalty that is fully eliminated by the new specification syntax.

Keep Backward Compatibility and Reduce Impact on Current Systems

Designing for backward compatibility was crucial for a smooth transition. The new configuration format doesn't need code changes for existing apps. To avoid disrupting other features, OpenSSL codebase tweaks were carefully made in “a few pinpointed locations” of the huge codebase.

Additional Implementation Considerations

A “?” prefix was added to ignore unknown algorithm names, handle pseudo-algorithm names like “DEFAULT,” and allow the client and server to use the same specification string (requiring the client to ignore server-specific delimiters and the server to ignore client-specific prefixes).

OpenSSL v3.5's Collaboration and Importance

Development involved considerable consultation and collaboration with the OpenSSL maintainer team and other expertise. The paragraph praises the “excellent interactions” throughout development.

OpenSSL v3.5 is “the first TLS library to fully adhere to the CNSA 2.0 mandate to prefer Q-safe algorithms.” Due to its Long-Term Support (LTS) status, Linux distributions are expected to adopt OpenSSL v3.5 more extensively, making these quantum-safe communication capabilities available.

Conclusion

OpenSSL v3.5 must have the Q-safe algorithm preference to safeguard internet communication from quantum computers. The developers satisfied the NSA's CNSA 2.0 criteria by cleverly increasing OpenSSL's configuration features without requiring large code modifications in OpenSSL-reliant applications or TLS standard changes.

Client-side prefix and server-side tuple-based preference systems give quantum-resistant cryptography precedence in a backward-compatible way, enabling a safe digital future. OpenSSL v3.5's LTS status ensures its widespread use, enabling quantum-safe communication on many computers.

Binary Copy (for direct file transfers)

Delimited Text & JSON (for structured data)

Table-based Movement (for databases like SQL Server, Snowflake, etc.)

2. Data Flow Types in ADF

2.1 ETL vs. ELT Approach

ETL (Extract, Transform, Load): Data is extracted, transformed in a staging area, then loaded into the target system.

ELT (Extract, Load, Transform): Data is extracted, loaded into the target system first, then transformed in-place.

ADF supports both ETL and ELT, but ELT is more scalable for large datasets when combined with services like Azure Synapse Analytics.

2.2 Batch vs. Real-Time Data Movement

Batch Processing: Scheduled or triggered executions of data movement (e.g., nightly ETL jobs).

Real-Time Streaming: Continuous data movement (e.g., IoT, event-driven architectures).

ADF primarily supports batch processing, but for real-time processing, it integrates with Azure Stream Analytics or Event Hub.

3. Best Practices for Data Movement in ADF

3.1 Performance Optimization

✅ Optimize Data Partitioning — Use parallelism and partitioning in Copy Activity to speed up large transfers.  ✅ Choose the Right Integration Runtime — Use self-hosted IR for on-prem data and Azure IR for cloud-native sources.  ✅ Enable Compression — Compress data during transfer to reduce latency and costs.  ✅ Use Staging for Large Data — Store intermediate results in Azure Blob or ADLS Gen2 for faster processing.

3.2 Security Best Practices

🔒 Use Managed Identities & Service Principals — Avoid using credentials in linked services.  🔒 Encrypt Data in Transit & at Rest — Use TLS for transfers and Azure Key Vault for secrets.  🔒 Restrict Network Access — Use Private Endpoints and VNet Integration to prevent data exposure.

3.3 Cost Optimization

💰 Monitor & Optimize Data Transfers — Use Azure Monitor to track pipeline costs and adjust accordingly.  💰 Leverage Data Flow Debugging — Reduce unnecessary runs by debugging pipelines before full execution.  💰 Use Incremental Data Loads — Avoid full data reloads by moving only changed records.

4. Common Pitfalls & How to Avoid Them

❌ Overusing Copy Activity without Parallelism — Always enable parallel copy for large datasets.  ❌ Ignoring Data Skew in Partitioning — Ensure even data distribution when using partitioned copy.  ❌ Not Handling Failures with Retry Logic — Use error handling mechanisms in ADF for automatic retries.  ❌ Lack of Logging & Monitoring — Enable Activity Runs, Alerts, and Diagnostics Logs to track performance.

Conclusion

Data movement in Azure Data Factory is a key component of modern data engineering, enabling seamless integration between cloud, on-premises, and hybrid environments. By understanding the core concepts, data flow types, and best practices, you can design efficient, secure, and cost-effective pipelines.

Fighting Cloudflare 2025 Risk Control: Disassembly of JA4 Fingerprint Disguise Technology of Dynamic Residential Proxy

Today in 2025, with the growing demand for web crawler technology and data capture, the risk control systems of major websites are also constantly upgrading. Among them, Cloudflare, as an industry-leading security service provider, has a particularly powerful risk control system. In order to effectively fight Cloudflare's 2025 risk control mechanism, dynamic residential proxy combined with JA4 fingerprint disguise technology has become the preferred strategy for many crawler developers. This article will disassemble the implementation principle and application method of this technology in detail.

Overview of Cloudflare 2025 Risk Control Mechanism

Cloudflare's risk control system uses a series of complex algorithms and rules to identify and block potential malicious requests. These requests may include automated crawlers, DDoS attacks, malware propagation, etc. In order to deal with these threats, Cloudflare continues to update its risk control strategies, including but not limited to IP blocking, behavioral analysis, TLS fingerprint detection, etc. Among them, TLS fingerprint detection is one of the important means for Cloudflare to identify abnormal requests.

Technical Positioning of Dynamic Residential Proxy

The value of Dynamic Residential Proxy has been upgraded from "IP anonymity" to full-link environment simulation. Its core capabilities include:

JA4 fingerprint camouflage technology dismantling

1. JA4 fingerprint generation logic

Cloudflare JA4 fingerprint generates a unique identifier by hashing the TLS handshake features. Key parameters include:

TLS version: TLS 1.3 is mandatory (version 1.2 and below will be eliminated in 2025);

Cipher suite order: browser default suite priority (such as TLS_AES_256_GCM_SHA384 takes precedence over TLS_CHACHA20_POLY1305_SHA256);

Extended field camouflage: SNI(Server Name Indication) and ALPN (Application Layer Protocol Negotiation) must be exactly the same as the browser.

Sample code: Python TLS client configuration

2. Collaborative strategy of dynamic proxy and JA4‌

Step 1: Pre-screening of proxy pools‌

Use ‌ASN library verification‌ (such as ipinfo.io) to keep only IPs of residential ISPs (such as Comcast, AT&T); Inject real user network noise (such as random packet loss rate of 0.1%-2%).

‌Step 2: Dynamic fingerprinting‌

Assign an ‌independent TLS profile‌ to each proxy IP (simulating different browsers/device models);

Use the ja4x tool to generate fingerprint hashes to ensure that they match the whitelist of the target website.

‌Step 3: Request link encryption‌

Deploy a ‌traffic obfuscation module‌ (such as uTLS-based protocol camouflage) on the proxy server side;

Encrypt the WebSocket transport layer to bypass man-in-the-middle sniffing (MITM).

Countermeasures and risk assessment

1. Measured data (January-February 2025)

2. Legal and risk control red lines

Compliance: Avoid collecting privacy data protected by GDPR/CCPA (such as user identity and biometric information); Countermeasures: Cloudflare has introduced JA5 fingerprinting (based on the TCP handshake mechanism), and the camouflage algorithm needs to be updated in real time.

Precautions in practical application

When applying dynamic residential proxy combined with JA4 fingerprint camouflage technology to fight against Cloudflare risk control, the following points should also be noted:

‌

Proxy quality selection‌: Select high-quality and stable dynamic residential proxy services to ensure the effectiveness and anonymity of the proxy IP.

‌Fingerprint camouflage strategy adjustment‌: According to the update of the target website and Cloudflare risk control system, timely adjust the JA4 fingerprint camouflage strategy to maintain the effectiveness of the camouflage effect.

‌Comply with laws and regulations‌: During the data crawling process, it is necessary to comply with relevant laws and regulations and the terms of use of the website to avoid infringing on the privacy and rights of others.

‌Risk assessment and response‌: When using this technology, the risks that may be faced should be fully assessed, and corresponding response measures should be formulated to ensure the legality and security of data crawling activities.

Conclusion

Dynamic residential proxy combined with JA4 fingerprint camouflage technology is an effective means to fight Cloudflare 2025 risk control. By hiding the real IP address, simulating real user behavior and TLS fingerprints, we can reduce the risk of being identified by the risk control system and improve the success rate and efficiency of data crawling. However, when implementing this strategy, we also need to pay attention to issues such as the selection of agent quality, the adjustment of fingerprint disguise strategies, and compliance with laws and regulations to ensure the legality and security of data scraping activities.

Cloud SQL Auth Proxy: Securing Your Cloud SQL Instances

Cloud SQL Auth Proxy

In this blog they will explain how to utilise the Cloud SQL Auth Proxy to create safe, encrypted data, and authorised connections to your instances. To connect to Cloud SQL from the App Engine standard environment or App Engine flexible environment, you do not need to configure SSL or use the Cloud SQL Auth Proxy.

The Cloud SQL Auth Proxy’s advantages

Without requiring authorised networks or SSL configuration, the Cloud SQL Auth Proxy is a Cloud SQL connection that offers secure access to your instances.

The following are some advantages of the Cloud SQL Auth Proxy and other Cloud SQL Connectors:

Secure connections:

TLS 1.3 with a 256-bit AES cypher is automatically used by this to encrypt traffic to and from the database. You won’t need to administer SSL certificates because they are used to validate the identities of clients and servers and are not dependent on database protocols.

Simpler authorization of connections:

IAM permissions are used by the Cloud SQL Auth Proxy to restrict who and what can connect to your Cloud SQL instances. Therefore, there is no need to supply static IP addresses because it manages authentication with Cloud SQL.

It depends on the IP connectivity that already exists; it does not offer a new way for connecting. The Cloud SQL Auth Proxy needs to be on a resource that has access to the same VPC network as the Cloud SQL instance in order to connect to it via private IP.

The operation of the Cloud SQL Auth Proxy

A local client that is operating in the local environment is required for the Cloud SQL Auth Proxy to function. Your application uses the common database protocol that your database uses to connect with the Cloud SQL Auth Proxy.

It communicates with its server-side partner process through a secure channel. One connection to the Cloud SQL instance is made for each connection made via the Cloud SQL Auth Proxy.

An application that connects to Cloud SQL Auth Proxy first determines if it can establish a connection to the target Cloud SQL instance. In the event that a connection is not established, it makes use of the Cloud SQL Admin APIs to acquire an ephemeral SSL certificate and connects to Cloud SQL using it. The expiration date of ephemeral SSL certificates is around one hour. These certificates are refreshed by Cloud SQL Auth Proxy prior to their expiration.

The only port on which the Cloud SQL Auth Proxy establishes outgoing or egress connections to your Cloud SQL instance is 3307. All egress TCP connections on port 443 must be permitted since Cloud SQL Auth Proxy uses the domain name sqladmin.googleapis.com to use APIs, which does not have a stable IP address. Make that your client computer’s outbound firewall policy permits outgoing connections to port 3307 on the IP address of your Cloud SQL instance.

Although it doesn’t offer connection pooling, it can be used in conjunction with other connection pools to boost productivity.

The connection between Cloud SQL Auth Proxy and Cloud SQL is depicted in the following diagram:

image credit to Google cloud

Use of the Cloud SQL Auth Proxy Requirements

The following conditions must be fulfilled in order for you to use the Cloud SQL Auth Proxy:

Enabling the Cloud SQL Admin API is necessary.

It is necessary to supply Google Cloud authentication credentials to this.

You need to supply a working database user account and password to this proxy.

The instance needs to be set up to use private IP or have a public IPv4 address.

It is not necessary for the public IP address to be added as an approved network address, nor does it need to be reachable from any external address.

Options for starting Cloud SQL Auth Proxy

You give the following details when you launch it:

Which Cloud SQL instances to connect to so that it can wait to receive data from your application that is sent to Cloud SQL

Where can it locate the login credentials needed to validate your application with Cloud SQL?

Which type of IP address to use, if necessary.

Whether it will listen on a TCP port or a Unix socket depends on the startup parameters you supply. It creates the socket at the specified location, which is often the /cloudsql/ directory, if it is listening on a Unix socket. The Cloud SQL Auth Proxy by default listens on localhost for TCP.

For authentication, use a service account

To authorise your connections to a Cloud SQL instance, you must authenticate as a Cloud SQL IAM identity using this Proxy.

For this purpose, the benefit of using a service account is that you may make a credential file particularly for the Cloud SQL Auth Proxy, and as long as it approach for production instances that aren’t operating on a Compute Engine instance is to use a service account

In the event that you require this to be invoked from several computers, you can replicate the credential file within a system image.

You have to make and maintain the credential file in order to use this method. The service account can only be created by users who possess the resourcemanager.projects.setIamPolicy permission, which includes project owners. You will need to get someone else to create the service account or find another way to authenticate this, if your Google Cloud user does not have this permission.
