METHOD OF CREATING ELECTRONIC DOCUMENT Russian patent published in 2014 - IPC G06K19/00 H04L9/36 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to legally valid electronic document management. In the method, a certification centre places, in the body of an electronic document, an additional authentic label on the security level of accessing a personal key of a person registered at the certification centre. The centre verifies the electronic signature of the sent document with a signed hash and creates a security level label containing a label number, a document hash, a current time stamp, information on security parameters of the personal key, then signs the label with a key of the certification centre and returns the signed label. Signature verification can be performed based on biometric authentication of the person that has signed the document, and the security level label of the personal key further includes information on the time and parameters of biometric authentication, which ensures more accurate determination of the time of possible compromise of the personal key.

EFFECT: high reliability of electronic documents.
