The widespread use of biometrics and its increased popularity introduces privacy risks. In order to mitigate these risks, solutions such as the helper-data system, fuzzy vault, fuzzy extractors, and cancelable biometrics were introduced, also known as the field of template protection. Besides these developments, fusion of multiple sources of biometric information have shown to improve the verif...

Multi-biometric systems are being increasingly deployed in many large biometric applications, because they have several advantages such as lower error rates. Multi-biometric systems require storage of multiple biometric templates (e.g., fingerprint, iris and face) for each user, which results in increased user privacy and system security. The features of fingerprint, iris and face are obtained....

Irrevocability is one major issue in existing bio-cryptosystems. In this paper, we proposed a cancellable bio-cryptosystem by taking the full advantage of cancellable and non-invertible properties of bio-hashing biometrics. Specifically, two transformed templates are generated by using the bio-hashing algorithm and applied into two different secure sketches, fuzzy commitment sketch and fuzzy va...

Biometric systems are subjected to a variety of attacks. Stored biometric template attack is very severe compared to all other attacks. Providing security to biometric templates is an important issue in building a reliable personal identification system. Multi biometric systems are more resistive towards spoof attacks compared to unibiometric counterpart. Soft biometric are ancillary informatio...

In this paper, we revisit the Forgotten Secret Recovering Scheme for k users, referred to as FSRS(k) previously proposed by the present author. FSRS(k) takes advantage of the fact that Reed-Solomon code used in FSRS(k) is constructed in a form of systematic code. We show that a particular class of FSRS(k), FSRS(1), can be successfully applied to the various cryptoscheme including Fuzzy Vault Sc...

the result of transvaginal sacrospinous ligament fixation technique, as part of the vaginal repair procedure for massive uterovaginal (pelvic organ prolapse stage iii and stage iv and vault prolapse) is evaluated. a total of 32 women were included in the present case series. marked uterovaginal prolapse was present in 28 women and four had vault prolapse following hysterectomy. patients with va...

Personal identification and authentication is very crucial in the current scenario. Biometrics plays an important role in this area. Biometric based authentication has proved superior compared to traditional password based authentication. Anyhow biometrics is permanent feature of a person and cannot be reissued when compromised as passwords. To over come this problem, instead of storing the ori...
