Feature Extraction Of Dorsal Hand Vein Pattern Using A Fast Modified Pca Algorithm Based On Cholesky Decomposition And Lanczos Technique

Palm-Vein Biometric Authentication system is a physiological pattern recognition technique that uses the vein patterns of an individual's palm for providing authentication. This paper presents a comprehensive comparative study of basic transforms: PCA (Principal Component Analysis), DCT, DST, Walsh-Hadamard and Slant for Palm Vein recognition. These transforms were implemented on a database consisting of 576 images, containing unmodified as well as modified images after noise introduction, brightness and contrast changes in the original images. Performance evaluation metrics FAR (False Acceptance rate), FRR (False Rejection Rate) and EER (Equal Error Rate) have been obtained. Then, comparative analysis of these methods has been done on the basis of performance evaluation metrics obtained, robustness of implemented system, feature vector size and time taken for execution. Results obtained showed that Walsh-Hadamard transform performs the best and can be successfully used for Palm Vein biometrics.

A biometric is defined as a unique, measurable, biological characteristic or trait for automatically recognizing or verifying the identity of a human being. Statistically analyzing these biological characteristics has become known as the science of biometrics. These days, biometric technologies are typically used to analyze human characteristics for security purposes. In this paper we describe a method for integrating together cryptography and steganography through image processing. In particular, we present a system able to perform steganography and cryptography at the same time using images as cover objects for steganography and as keys for cryptography. In this paper we will present some schemes for strengthening personal authentication over insecure channels with biometric concepts or how to securely transfer or use vein biometric characteristics. Our concept can be applied on any biometric authentication scheme and is universal for all systems
