Secure remote delegation method for a biometric recognition system

A remote delegation method for a biometric recognition system comprising a computer device of the delegator, a server and an object to be protected, the method comprising:

• 01-D01:
• the computer device of the delegator constructing a profile of the delegatee, said profile comprising a first biometric capture of the delegatee and a smartphone number of the delegatee;
• 02-D02:
• the computer device of the delegator configuring usage parameters of the delegatee and adding them to the profile of the delegatee;
• 03-D03:
• the computer device of the delegator transmitting the profile of the delegatee to the server;
• 04-S01:
• the server creating an encryption key;
• 05-S02:
• the server transmitting the profile of the delegatee and the encryption key to the object to be protected;
• 06-V01:
• the object to be protected extracting a first biometric template from the first biometric capture of the delegatee and the object to be protected creating a first unique identifier for the delegatee assigned a “pending validation” status;
• 07-V02:
• the object to be protected transmitting the first identifier to the server and deleting the first biometric capture;
• 08-V03:
• the object to be protected authorizing the reading of a graphic code by its sensor;
• 09-S03:
• the server encrypting the first identifier using the encryption key and the server creating a graphic code containing the encrypted first identifier;
• 10-S04:
• the server transmitting the graphic code to the smartphone of the delegatee, using its number;
• and
• 11-S05:
• the server destroying the encryption key.
