Coset decomposition method for storing and decoding fingerprint data
نویسنده
چکیده
Biometrics such as fingerprints, irises, faces, voice, gait and hands are often used for access control, authentication and encryption instead of PIN and passwords. In this paper a syndrome decoding technique is proposed to provide a secure means of storing and matching various biometrics data. We apply an algebraic coding technique called coset decomposition to the model of fingerprint biometrics. The algorithm which reveals the matching between registered and probe fingerprints is modeled and implemented using MATLAB.

Coset Decomposition Method for Decoding Linear Codes
We introduced an application of the decomposition of a group into cosets of a subgroup to the theory of error detecting and correcting codes. The proposed approach is based on the general method for decoding linear codes known as syndrome decoding. Mathematics Subject Classification: 20A05; 20B05; 20B40
متن کاملA Spatial Method for Watermarking of Fingerprint Images
This paper extends the watermarking method introduced in [1] in order to embed watermark data into fingerprint images, without corrupting their features. Two methods are proposed. The first method inserts watermark data after feature extraction thus prevents watermarking of regions used for fingerprint classification. The method utilizes an image adaptive strength adjustment technique which res...
متن کاملOn the Pless Construction and ML Decoding of the Quadratic Residue Code
We present a method for maximumlikelihood decoding of the quadratic residue code This method is based on projecting the code onto a subcode with an acyclic Tanner graph and representing the set of coset leaders by a trellis diagram This results in a two level coset decoding which can be considered a systematic generalization of the Wagner rule We show that unlike the Golay code the code does no...
متن کاملA Novel Approach for Detection of Fingerprint by Constructing Relational Graph using Singular Points
Fingerprint is the dominant trait between different biometrics like iris, retina, and face. A fingerprint is the pattern of ridges and valleys on the surface on a fingertip. Now days itself this method is very powerful because of their immutability and uniqueness of patterns .immutability means the patterns by ridges and valleys are permanent and unchanged. Many techniques have been proposed fo...
متن کاملOn Step-by-Step Complete Decoding Triple-Error-Correcting Binary BCH Codes
The decoding beyond the Bose-Chaudhuri-Hocquenghem (BCH) bound is always an interesting research topic in block error correction codes. However, searching a complete decoding algorithm is not easy since all the error patterns that belong to the coset leaders of the standard array need to be correctable [1]. Both the well-known standard algebraic method and the step-by-step method can be used to...
