Abstract: A major concern nowadays for any biometric credential management system is its potential vulnerability to protect its information sources; i.e., protecting a genuine user’s template from both internal and external threats. These days’ biometric authentication systems face various risks. One of the most serious threats is the vulnerability of the template's database. An attacker with access to a reference template could try to impersonate a legitimate user by reconstructing the biometric sample and by creating a physical spoof. Susceptibility of the database can have a disastrous impact on the whole authentication system. The potential disclosure of digitally stored biometric data raises serious concerns about privacy and data protection. Therefore, a method which would integrate conventional cryptography techniques with biometrics is proposed. In this research, a biometric crypto system is presented which encrypts the biometric template and the encryption is done by generating pseudo random numbers, based on non-linear dynamics.
