A biometric signature is a solution that allows you to sign documents with a handwritten signature on any mobile device (tablet, smartphone) with full legal validity.
The Docuten mobile application sends the signed document with the biometric information encrypted in the document itself, providing complete legal guarantees. This ensures the inalterability of the document since it’s impossible to modify it after signature.
The biometric information of a signature is made up of: speed in x, speed in y, acceleration in x, acceleration in y, angular accelerations, pressure variation, pseudo pressure, number of strokes, order of strokes, trace durations, etc.
Biometric data is encrypted in the application itself with the public component of an encryption key. The private component is stored by the certification authority or notary that generated it, and only upon court request is this used to decrypt the biometric information.
