Automated fingerprint identification systems (AFIS) in law enforcement and border control applications have increased the need to ensure that these systems are not compromised. Although several issues related to the security of the fingerprint system have been studied, including the use of fake fingerprints to mask identity, the problem of tampering or obscuring fingerprints has received very little attention. attention. Fingerprint obfuscation refers to the deliberate modification of the fingerprint pattern by an individual in an attempt to obscure their identity. Several cases of hiding fingerprints have been reported in the press. The NFIQ algorithm is also used to evaluate the large database of altered fingerprints. We also proposed the NFIQ2.0 algorithm to examine the fingerprint. This algorithm follows the steps 1. Improve the quality of the image (fingerprint) from the database 2. Convert them to high quality fingerprints. Then the process similar to the NFIQ. This result shows the feasibility of the proposed NFIQ2.0 approach to detect altered fingerprints.1 INTRODUCTIONFingerprint recognition has been successfully used by law enforcement agencies to identify suspects and victims for almost 100 years old. Recent advances in automated fingerprint identification technology, coupled with the growing need for reliable identification of people, have resulted in increased use of fingerprints in government and civilian applications such as border control, security verification, professional background and secure access to facilities. The success of fingerprint recognition systems in accurately identifying individuals has prompted some individuals to take extreme measures to circumvent these systems. The main purpose of altering fingerprints...... middle of paper ...... has prompted some people to take extreme measures to evade identification by altering their fingerprints. The problem of tampering or obfuscation of fingerprints is very different from that of fingerprint theft, where an individual uses a false fingerprint in order to adopt the identity of another individual. Although the problem of identity theft has received considerable attention in the literature, the problem of obfuscation has not been addressed in the biometric literature, despite many documented cases of fingerprint modification in the aim of evading identification. Although obfuscation can be experienced with other biometric modalities (such as face and iris), this problem is particularly significant in the case of fingerprints due to the widespread deployment of AFIS in government and government applications. civil rights and the ease with which fingerprints can be obscured..
