In the area of behavioral biometrics are voice recognition technologies that provide telephone authentication. One system uses extraction and pattern-matching algorithms embedded on computer chips to analyze voices. The system needs a scanner and a smart "voice card," but producers are looking ahead to wiring its system into the Internet, where it can be configured as a verification server. Users favor voice verification. Several large corporations employ voice verification to protect computer, office, lab, and vault access. In addition, several s

Signature verification is the process used to recognize an individual’s hand-written signature. Dynamic signature verification is a biometric technology that is used to positively identify a person from their handwritten signature. This is done by analyzing the shape, speed, stroke, and pen pressure and timing information during the act of signing the signature. The key in signature dynamics is to differentiate between the parts of the signature that are habitual and those that vary with almost every signing. Some devices also factor in the static image of the signature, and some can capture a static image of the signature for records or reproduction. Static signature capture is becoming quite popular as a replacement for pen and paper signing in bankcard, PC and delivery-service applications. Generally, verification devices use wired pens, pressure-sensitive tablets, or a combination of both. Devices using wired pens are less expensive and take up less room but are potentially less durable. To date, the financial community has been slow to
