The claimed solution consists in the steps of generating, issuing and validating a security code (112) in QRCode format (11) or Data Matrix format (12) which can be printed on physical media (21), displayed on an electronic screen (22), or stored in electronic chips (23) by radio frequency identification (RFID) (13) or near-field communication (NFC) (14) technologies. The code is generated using encryption (8), authenticated cryptography (9) and digital identities or certificates issued according to the public key infrastructure (PKI) standard by a trusted certification authority (111), allowing the code to be validated, either with (online) or without (offline) connectivity to a data network (115), by means of an installed application (120), by a process of reading (31), crytographic validation (34) and decryption (35) which allows the content of the security code (112) to be released. Optionally, it is possible to obtain the geolocation of the issuance (3) and validation (33) of the security code (112), together with the identification of the end user (32). |
