Patent number: 11038693Abstract: The invention relates to a method for validating message strings through a decentralized network. Said method also makes it possible to manage the validations of messages relating to a message chain in a unitary and asynchronous manner thus rendering the process unlimited in terms of performance. The method also allows enhanced security and confidentiality, in particular by integrating the number and geolocation constraints of message validations. The method thus makes it possible, through a decentralized network of trusted third parties with limited confidence, to restore real trust to the users.Type: GrantFiled: September 18, 2018Date of Patent: June 15, 2021Inventor: Sebastien Dupont
