1. A method for tracing a digital information element in a computer system comprising electronic devices of a plurality of users and an archiving system for archiving digital information elements comprising a first blockchain-type distributed database, the method comprising:
receiving the digital information element from an electronic device of a user of the plurality of users, wherein the digital information element includes digital information of technical information in a form of text and drawings of a timepiece,
archiving said digital information element, said archiving step comprising generating an identification element indicating a version of the digital information element including the digital information of the timepiece, wherein the archiving step comprises storing both the digital information element and the generated identification element in a second database of the archiving system to which the electronic devices of the users are connected, the second database being different from the first database, and
adding, to the first database, the generated identification element having been signed using a secure element, being a key or a certificate, associated with said user and/or the electronic device, said adding step comprising encrypting the generated identification element using a cryptographic algorithm and the secure element, the cryptographic algorithm using at least one metric variable associated with the user to encrypt the generated identification element,
wherein the at least one metric variable used by the cryptographic algorithm includes a date on which the adding step is initiated and a biometric variable relating to biological characteristics of the user and is different from the secure element used in the signing of the generated identification element.
