Hervé Cadieu started the Grapho-Lock project in 1998 as a way to certify one's identity with a dynamic signature verification algorithm Grapho-Lock project has evolved. We have then decided to blend the legacy graphical handwritten signature with the new digital signature so that there is no more confusion between what is a signature to author and seal a dematerialized document with a reliable time-stamp.
Laurent Cadieu joined the project in 2006 as early investor and manager.
Sylvain Bruyere has led the project coding developpements since late 2006.
Nowadays Grapho-Lock allows to : Identify securely a user, (by mean of his fingerprints or by dynamic signature authentication, or by password), then to let this known user sign any Microsoft® Office documents with the graphical handwritten signature binded to his user profile sealed automatically with a PKI X509 digital signature, this operation is time-stamped with a reliable time-stamp provided by Grapho-lock web service to guarantee when this process has taken place.
Biometric technologies to identify the user, then providing a wrapper in Microsoft® Office softwares in order to smooth the digital signature adoption. Digital signature becomes as easy as signing a papersheet.
We adapt the new technologies implementation to your behaviour and habits instead asking you to change the way you are working.
