The importance of security in mobile apps is undeniable and in the blog post on the application security issues to avoid we have already explained a little about it. In this article we are going to tell you about the advantages of including biometric systems in apps and how it is a fundamental solution.

Importance of Security in Mobile Applications

In an era dominated by digital interactions, the protection of sensitive data within mobile applications is paramount. Growing privacy concerns require advanced security measures.

Biometric Systems in Apps

Biometric systems in applications offer a state-of-the-art solution to security challenges. These systems leverage unique biological traits for user identification, adding an additional layer of protection.

What are Biometric Systems

Understanding the fundamentals of biometric systems is key to appreciating their role in application security.


Biometric systems are mechanisms that identify individuals according to their unique physiological or behavioural characteristics. These systems have proven to be highly effective in improving security protocols.

Types of Biometric Systems

Exploring the various types of biometric systems provides insight into their versatility and application.

Fingerprint recognition

Fingerprint recognition is a widely adopted biometric method, which offers a fast and reliable way of user authentication.

Facial Recognition

Facial recognition adds a layer of convenience and security by analysing facial features for user verification.

Voice Recognition

Voice recognition technology uses unique voice patterns, offering a hands-free and secure method of authentication.

Recognition of Iris

Iris recognition scans the unique patterns of the iris, providing a highly accurate form of biometric authentication.

Behavioural Pattern Recognition

Analysing behavioural patterns, such as handwriting dynamics, offers a nuanced approach to biometric identification.

Advantages of Incorporating Biometric Systems

The integration of biometric systems in mobile applications brings a multitude of advantages.

Improving Security

Biometric authentication improves security by replacing traditional methods such as passwords, reducing the risk of unauthorised access.

Improved User Experience

The seamless and user-friendly nature of biometrics improves the overall user experience, eliminating the need for complex passwords.

Fraud Prevention

Biometric measures act as a formidable deterrent to fraudulent activities, as duplicating unique biological traits is exceptionally difficult.

Regulatory Compliance

Complying with regulatory standards becomes more affordable with the implementation of robust biometric security measures.


Successful integration of biometric systems requires careful consideration of the technical aspects.

Technical Considerations: Hardware and Software Requirements

Ensuring compatibility with appropriate hardware and software is crucial for the effective operation of biometric systems.

Mobile Application Integration: In-House Development vs. Third-Party and Compatible Platforms

The decision between in-house development and third party integration depends on factors such as budget, expertise and time constraints.

Today, there are a number of third-party biometric solutions that can be easily integrated into mobile applications to enhance security and user experience.

  • Microsoft Azure Face API: Azure Face API, of Microsoft, offers accurate and fast facial recognition. It can identify and verify faces in images and videos, making it ideal for applications that require a strong authentication system.
  • Google Cloud Voice API: Google Cloud Speech API enables real-time speech recognition integration. Perfect for applications seeking voice authentication, it provides a seamless and secure experience.
  • VeriSpeak Voice Recognition SDK: VeriSpeak, an SDK from Neurotechnology, is known for its speech recognition accuracy. It can be integrated into applications for voice-based biometric authentication with high security standards.
  • BioID Facial Recognition: BioID offers a cloud-based facial recognition service. Its API allows for easy integration into applications, providing an additional layer of security through face verification.

These examples are a sample of the many options available to developers looking to implement biometric systems in their applications. The choice will depend on the specific needs and compatibility with the security vision of the application.

Security Factors: Biometric Data Storage and Authentication Processes

Protecting biometric data and establishing secure authentication processes are key to maintaining the integrity of the system. In addition, the correct handling of biometric data and the implementation of secure authentication processes are essential to ensure the robustness and reliability of a biometric system in mobile applications.

Biometric Data Storage

The secure storage of biometric data involves the implementation of advanced measures to protect the most sensitive user information. Here are some key issues to consider:

  • Strong Encryption: Implementing strong encryption techniques is essential. Biometric information must be encrypted both at rest and during transmission, using state-of-the-art algorithms to prevent unauthorised access.
  • Decentralised Storage: Opting for a decentralised storage approach can reduce the risk of massive vulnerabilities. Distributing biometric data in different locations strengthens security and makes unauthorised access more difficult.
  • Rigorous Access Management: Establishing rigorous access management ensures that only authorised persons have the ability to access biometric data. This includes implementing measures such as two-factor authentication for staff with access permissions.

Secure Authentication Processes

Authentication is at the heart of biometric security. Developing robust and secure processes ensures that user identification is reliable and resistant to fraudulent attempts.

  • Multi-factor: Incorporating multi-factor authentication adds additional layers of security. In addition to biometric data, the combination with another form of authentication, such as a password or a temporary code, enhances overall security.
  • Continuous Monitoring: Implementing continuous monitoring of system activity is crucial. Detection of unusual patterns or repeated authentication attempts can alert to potential threats and enable immediate responses.
  • Periodic Updates: Keeping authentication processes up to date is essential to cope with evolving threats. Periodic updates may include improvements to biometric algorithms and adjustments to security settings.


In conclusion, the integration of biometric systems in mobile applications is a strategic move towards enhanced security and a superior user experience. At Yapiko we are aware that as technology advances, incorporating these innovative solutions is not just a choice, but a necessity to maintain security in app development.
