摘要：The encroachment of information is considered the most importantattack thataffectsthe performance of thenetwork. Biometric based authentications have emerged as promising components of information security.Biometricisusedfor two majorpurposes:identification and authentication. We propose a palm based authentication method that uses handimages to define a set of referencing points considered as invariable and unique in the authentication process.The method ofcircular histogramanalysis has been used to enable the definition of the angular orientation of palm representation and thecorner of turn where it is necessary to turn the image for correct determination of supporting points which is based on two-dimensional discrete differentiationsof image with the next analysis of given points of brightness projections forming thecurves of peaks and cavities of hand-fingers and facilitating the searching process for such given points. The system of signs-recognition, which allows authentication of identity, regardless of palm location and its position withinthe limits of thescanning fieldhas been used and proved to be economic and capable of improving the operability of the authentication system
