Use of Multimodal Biometric System for the Authentication and Security

Abstract

We know that security is the main challenge of the modern era, there may be many techniques and methods used for providing the security of any system or data. The biometric system is the widely used method for security. The biometric security is more secure method then others like passwords, card etc. In biometric the part of the body with some uniqueness use as the input image. But now a day the use of single biometric is not more secure, so the alternative or solution of this problem is to use the Multimodal biometric system. In a multimodal system more than one biometric trait used for providing security and authentication to a system. The images are stored in the database by using different operations on the images for compare it by input images. There are some steps used in processing of multimodal biometric system like as ROI, feature extraction and matching.
