Novel Template Protection Scheme for Multimodal Data

A popular form of technology used for securing data is ‘biometrics’. Biometrics are stored as templates, which are nothing but a digital reference of the unique characteristics extracted from the biometric, usually stored in a database which are used for authorizations and encryption. The concern for security of storage of templates is mainly due to the fact that the templates may not always be securely stored, and if a hacker does manage to crack the database, the attacker may find all the data stored in the template use it pilfer other important data or obtain access to confidential secrets. This paper suggests a novel scheme where in the fingerprint are stored safely using multi-modal biometric, namely iris, salting and chunking. It also proposes an efficient way to detect presentation attacks which using salt.
