Signature biometrics
How does a signature biometric system work
Biometric signature recognition systems will measure and analyze the physical activity of signing, such as the stroke order, the pressure applied and the speed. Some systems may also compare visual images of signatures, but the core of a signature biometric system is behavioral, i.e. how it is signed rather than visual, i.e. the image of the signature.
Benefits of signature biometric systems
- While it is easy to copy the image of a signature, it is extremely difficult to mimick the behavior of signing
- Low False Acceptance Rates (FAR)
- People are used to sign documents, so signature recognition systems are not perceived to be invasive
Weaknesses of signature biometric systems
- People may not always sign in a consistent manner
