The Role of Biometric Technology in Access Control Systems
Biometric security measures such as fingerprints, iris patterns and facial features offer superior protection compared to access cards that can easily be copied or stolen, and passwords that can easily be cracked - thus making them the ideal solution for high-security facilities. These solutions also create an audit trail and increase employee accountability by eliminating the need for employees to carry access cards or recall PIN codes. Identification Biometrics can be used to accurately identify individuals either actively, with user participation, or passively (such as in surveillance applications). A biometric device must include at least one sensor which measures physical characteristics like fingerprints, faces, iris and vein patterns - along with software which digitizes this data and compares it with an identity template stored within its system. Once the identity template has been registered in the system, it can be compared with biometric data presented by the user during acc...
