Abstract

The method is implemented in a computer system deployed through the internet and interacts with a blockchain (BKC). Document issuers and validators are connected to the system. The method comprises generating a master key (MK) assigned to an issuer, certifying a document (DocData) through a first process (P2) including generating a document persistence key (PK), encrypting document data (CredData) with an encryption algorithm (AES) and an encryption key (KAES) derived (partial) from the master key, the document persistence key and an intermediate key (IK), registering encrypted document data (EncData) in the blockchain, and generating a web address (URL) carrying recovery information of the certified document; reading the document through a second process (P3) accessible to the web address, the second process including recovering the encrypted data in the blockchain and an access to the three keys, decrypting the encrypted data using the encryption key derived from the three keys, and displaying the document; and upon request from a legitimate holder of the document erase the persistence key.

Description

technical field [0001] The technology herein relates to computer systems and computer-based methods designed to ensure the authenticity and integrity of documents such as academic documents and diplomas, as well as citizenship, official and other sensitive documents. More specifically, the techniques in this paper relate to computer systems and processes that associate blockchains with advanced cryptography to authenticate documents in a secure and sustainable manner in compliance with regulations on personal data and the right to be forgotten. Background technique [0002] In today's digital and networked society, the necessity of preventing document forgery is becoming increasingly prominent. Many departments, agencies and organizations are faced with the scourge of falsified documents. For example, the impersonation of fake diplomas or falsified qualifications on resumes and social media is a fact of life affecting schools, universities, graduates and employers. Diploma...
