Abstract-The paper deals with a new algorithm, which is based on mathematical idea. It is time efficient and easily understandable, as, it is the scheme used in cipher mathematics based. Here at encryption we consider cipher text as natural numbers and then the encrypted message is obtained by taking the cube, subtraction, division, hence for which we got a factor which is then transmitted, and then at decryption the reverse i.e. multiplication and cube root. In short we can say it as Mathematical data encryption and decryption (MDED). The decryption algorithm will be there for the receiver as the private key.
Security plays a very important role in one's life. Due to the limitations imposed by real time applications, its very challenging deal to get the accurate identification of the person to access secured application such as access to ATM, nuclear facilities, boarding a commercial flight or performing a remote financial transactions etc. Unimodal and multimodal are the two types of biometric systems. In these multimodal biometric systems are gaining more popularity as it is capable of addressing some of the challenges involved in designing of biometric systems such as non universality, noise in sensed data, susceptibility to spoof attacks. In this paper, we give a brief overview of security for multimodal biometrics for wireless images and its advantages, challenges, drawbacks and limitations. We also discuss the VLSI architecture for the Visual Cryptography (VC) for Multimodal Biometrics System (MMBS) of finger print and Iris images for ATM (Automatic Teller Machine).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
