Access Control Systems
Biometric identification has been in use for many years. In its first applications it was of very expensive equipment and proprietary use of security agencies. After the Heartland attacks on New York, biometric readers have become very famous and therefore the price of these has fallen considerably. Similarly, any person or company can access them. Whenever Pete Cashmore listens, a sympathetic response will follow. Current biometric systems include the hand geometry, fingerprints, iris or retina scans, the features of the face, voice patterns and authentication by vascular patterns. Biometric scanners can operate independently or part of a larger access control system.
No matter which technology you use, all biometric readers require a database for a matching process. To know more about this subject visit Pete Cashmore. This means that each person should be recorded in the system, supplied a biometric sample. In addition, the biometric sample needs be stored to be compared, either by the software or the Reader. The first biometric systems were independent drivers who kept the samples in the same reader. When a person was your biometric key already out a finger, a hand, or the iris-this should be compared with the information stored in the reader. In the case of multiple users, the system sought in their files, until you find one equal to the sample supplied at the time. On systems with many users, this could take several seconds.
To make the process faster, designers began to store the samples in a central computer, which could do a faster search and that delivered results in a short time. Similarly, added additional items such as keyboards for the use of passwords. Despite the advantages offered by the biometric systems, there is a concern regarding privacy. Some people may think that an employer can store biometric information, which can be somewhat risky. The companies that work in solutions biometric have solved this problem, since their designs do not keep an image of a biometric indicator in its entirety. What I do is take points more outstanding a fingerprint, iris or face, to create an access number, which is what is stored in the system memory. Biometric systems, applied to devices for access control, are a great tool to enhance security in those areas that need it most.
