Biometric Authentication

Biometric authentication refers to the identification of humans based on physical or behavioural characteristics. Examples of biometric modalities include face, fingerprint, retina and iris identification. The choice of modality depends on the requirements of the application, e.g. the desired level of security, the acceptable level of intrusiveness, and the maximum hardware and software cost. For example, fingerprint scanners are typically used for computer logon while face and gait recognition are the most suitable modalities for CCTV surveillance applications. The company staff has more than 15 years of experience in applying computer vision technology in the domain of biometric authentication.

Example application: Hand geometry identification

Hand geometry identification systems were the first widely spread biometric systems, introduced already in the mid 1980s. The hand geometry devices perform the identification by extracting and comparing basic features such as distances between different landmarks on the hand. A camera captures either a top or bottom view of the hand, and in some cases also a profile view using an angled mirror. Features such as finger lengths, knuckle distances, hand thickness and height are combined into a compact template to be used in identification. The benefits of hand geometry systems include robustness, ease of use, low intrusiveness and straightforward integration. hands
