Biometric fusion is the use of multiple biometric traits from different sources obeserved by Bahaa Abdul Hussein. Fusion makes biometric authentication secure, enhancing its integrity. While biometric fusion is conceptually a sound system, there are many challenges involved in its implementation. Read on to know the challenges and solutions to take on these challenges.
Challenges in implementing Biometric fusion
Biometric fusion implementation has increased with increasing in attacks like spoofing and virtual identity authentication. Using multiple biometric traits in biometric fusion ensures greater level of security. Technology advancements have ensured that biometrics has become easier to use. It is also convenient for users and offers them a better user experience.
However, there are challenges involved in biometric fusion implementation. These include:
- Developing a multi biometric system for biometric fusion requires investments in equipment and software.
- Spoofing remains a concern with attempts being made to spoof the system using fake data. The system designed needs to prevent spoofing.
- The biggest challenge in biometric fusion implementation is privacy. Whenever biometrics of users are collected, there is a risk of their privacy being breached. Users are concerned over confidential data being leaked. User identification may also be misused for surveillance and other purposes.
- Two major technical challenges involved in biometric implementation are FAR and FRR. FAR stands for False Acceptance Rate where an unauthorised user is authenticated due to an error. FRR is the converse where an authorised user is refused access due to error in recognising the user.
The above challenges are major issues and must be addressed while creating a system for biometric fusion implementation.
Solution for tacking challenges in implementing biometric fusion
To overcome the challenge of privacy, it is very important to develop a robust system. The system must address privacy concerns and ensure that user data access is not given to anyone who does not need them. Database protection needs to be secure to prevent access by unauthorized persons.
Technical errors like FAR and FRR can crop up due to various reasons. Strengthening the authentication algorithm is a solution to manage this major challenge. Also proper guidelines for collecting biometric data ensures that the data is properly captured to avoid problems later at the authentication stage.
With advances in technology, biometric systems have become robust. Features like liveness detection has ensured that spoofing is almost impossible. Advances in technology and competition has brought down prices making it easier for businesses to invest in this technology.
