Biometric Signature Technology

Take legally valid digital signatures from your tablet and mobile phone.

What is a biometric signature?

Biometric signature Verification technology uses hand-written signature behavior Biometers to authenticate a computer user. Biometric signature verification is done by analyzing the shape, speed, impact, pen pressure and timing information during the signing process.  Biometric signature verification, instead of a password or PIN number, is a biometric technology that is used to accurately identify a person’s handwriting signature.

DocCastle Biometric signature scanning technology uses different aspects of the signature to authenticate people. In contrast to the comparison of visual images of the DocCastle signatures, it examines the behavioral components of the signature, such as the stroke sequence, speed and pressure. Unlike traditional signature comparison technologies, signature screening measures the physical activity of signing. In this way, the signature is verified only by the signature owner.
