Palmprint Authentication Based Access Control System

Identification refers to the modern automatic identification technology, automatic identification technology is able to automatically identify verification, and identification information into the computer of a modern detection methods. In communications technology and computer technology based on the full development of the formation of an integrated technology.Biometric identification technology as a modern one of the main means of getting more and more widely used in industries. Biometric technology is, through the computer and optics, acoustics, biological sensors and other high-tech biometric principles closely, using the inherent physiological characteristics of human behavioral characteristics and personal capacity to carry out identification technology.With the current increase people's safety awareness, identity and identification requirements are also increasing. The traditional identification methods, including identity items (such as keys, certificates, ATM cards, etc.) and identity of knowledge (such as user names and passwords) but since the main use of external objects, as if to prove the identity of stolen goods and identify knowledge or forgotten, its identity to impersonate others, or easily replaced.Biometric methods of identification than the traditional and more security, confidentiality and convenience. The main advantages of biometrics is to a large extent to reduce and eliminate counterfeit identity, while reducing administrative costs, replacing the artificial identity authentication process, largely to facilitate the user to reduce or eliminate the use of cards key or password to bring trouble. Biometrics with difficult forgotten, security performance, easy to counterfeit or stolen portable "portable" and the advantages available anywhere.Biometric technology through years of development, now has become part of daily life for the well-known biometrics, including: fingerprint identification, face recognition, voice recognition, iris recognition and other technological means, and for those existing means of identification, one of acceptance, and cost vary, so a large extent, restricted the development of the technology.Today's society a high degree of information networks, information security and demonstrate the importance of an unprecedented, personal identification technology is a very important value. Biometrics its unique stability, uniqueness and convenience provided us with a safer, more convenient and cost-personally identifiable manner. Given this under the influence of an application as biometrics, access control systems in the industries, the traditional access control system is used in most card recognition technology to design the proposed access control system design approach is based on palmprint recognition method of access control systems, compared to traditional access control system has the following advantages: First, as tested by testing the palmprint image, and therefore do not have the identification cards designed to save a part identification card the cost approach, and secondly, thanks to the way that palmprint recognition, there is no traditional way of forgetting to happen at the same time there is no SIM card missing after the trouble. Rapid development in technology today, people growing awareness of information security, in this context, identity recognition technology more and more applications to various industries, reflecting the identification of significant value. Identification technology, biometric technology driven forward, because the stability of biological characteristics, uniqueness, universality, which makes it an identifiable area of the main means of identification. Palmprint as a biometric, with easy access, features clear, stable and strong features can be analyzed, while the palmprint recognition system with an intuitive, friendly interface, so that collectors have a high degree of acceptance, so , palmprint recognition technology in recent years has been widely applied and development.This study was designed to simulate the palmprint authentication based access control system, mainly from the palmprint identification and access control systems to make both of the control circuit. Palmprint recognition, a move the palm of the location, feature extraction, feature matching combined with practical application of the concept of doing analysis and demonstration, in the full study of the location and palmprint recognition under the premise of understanding the actual palm prints collection process there are public safety and the environment unstable environment objective problems after imaging, access control system for the proposed use of hand contour information, and refers to the root point in the contour chain code of the location positioning method of contour feature points, the interception of the corresponding metacarpal grain region of interest (ROI), using 2D-Gabor method of palmprint feature extraction, to achieve the palm of the recognition process. Access control system, mainly the control circuit is designed. The main purpose of this study is to improve the traditional means of identification, biometric technology as an application.To better simulate the working process of access control systems, this paper provides Matlab Image Acquisition Toolbox and GUI features designed and implemented a set of palmprint authentication based on-line access simulation system to achieve the online palmprint image acquisition, preprocessing, feature extraction and feature matching process, and a corresponding identification experiment to simulate the working process of the access control system, simulation system has a high recognition rate. Simulation System Design and Implementation of access control systems help to shorten the development cycle, the foundation for future applications. The design of this issue through that area in the access control using the new means of palmprint recognition application with good results, for future application to palmprint recognition technology to other industries to do a very good bedding.
