Visual cryptography for MMBS of wireless images for ATM banking

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).
