Abstract

AbstractIn this paper, a new scheme for biometric data security has been proposed.Fingerprint minutiae havebeen hidden in face templatesat feature level rather than image level.Facial templates areconstructedby extracting small block of coefficients matrix resulting from applying DCT on face images. First,we propose a new encryption algorithm based on arithmetic coding to encrypt the fingerprint minutiaepoints. Then, minutiae codes are embedded in facial feature vectors using a new embedding methodbased on XOR to produce a stego-template. The influence of hiding process on the performance offace recognition system was tested. The experiments showed that the degradation was not raised insystem accuracy. So, the proposed scheme can be implementedto secure the sensitive data in amultibiometric system that combines face and fingerprint to authenticate individuals.

Abstract

In this paper, Framelet and Walsh transform are proposed for transformation, and then using arithmetic coding for compress an image. The goal is to achieve higher compression ratio by applying two levels Framelet transform (FLT), and then apply 2D Walsh-Hadamard transform (WHT) on each 8x8 block of the low frequency sub-band, while all other sub-bands are ignored. Experimental results show that the proposed algorithm gets best possible solution for tradeoff between compression ratio (size of image) and quality of compressed image, Peak Signal to Noise Ratio (PSNR). The simulation was carried using MATLAB software package version 2014. In this work, experiments were carried out on the gray scale and colored images.
