First Claim
Patent Images
1. A method of generating at least one derived identity of an individual (1) to be used by a service supplier, the method comprising the following steps:
- generating a first identifier (id1) from biometric data (5) of the individual using a user device;
defining a serial number (ns) associated with the individual by a service supplier device;
generating first check data (ctrl1) by the service supplier device for verifying consistency between the first identifier (id1) and the serial number (ns);
concatenating the serial number (ns), the first identifier (id1), and the first check data (ctrl1) by the service supplier device in such a manner as to form a first derived identity (ident1) of the individual; and
storing the first derived identity in the user device, whereinwhen the individual gains access to a service of the service supplier using the first derived identity stored in the user device, it is not possible to identify the individual from data of the individual stored in the service supplier device.
