DATA MEDIUM FOR THE CONTROL OF ENTITIES, AND DEVICE AND METHOD FOR THE CONTROL OF ENTITIES
First Claim
1. Data medium (1) comprising at least one identity zone (3) capable of storing identity data relating to the identity of the entity (6a, 6b) to which is intended to be assigned, wherein said identity data is capable of being accessible only by at least one qualified identity control unit (11), characterized in that it comprises at least one electronic chip (2) equipped with at least one group zone (4) capable of storing group data relating to the belonging of said entity (6a, 6b) to at least one group (5a, 5b), said group data being protected by at least one gate so as to be accessible only by at least one qualified group control unit (13) having an access key for said gate, said group zone (4) being capable of being updated only by means of a qualified updating unit (12) having an access key for said gate, with the updating being performed by the addition of at least one complementary group data item incrementing, without altering, said group data previously stored on the basis of the passage of said entity (6a, 6b) from one group (5a, 5b) to another group (5b, 5a) so as to generate a history of belonging of said entity (6a, 6b) to said successive groups (5a, 5b), with said group zone (4) being capable of preserving said history.

Abstract
The invention relates to a data medium (1) comprising an electronic chip provided with an identity zone storing identity data relating to the entity (6a, 6b) and a group zone storing group data relating to the membership of the entity (6a, 6b) to at least one group (5a, 5b). The invention also relates to a device (10) for controlling entities, comprising: data media (1); an identity control unit (11) enabled and able to recognize the identity data; an updating unit (12) enabled and able to update the group data as a function of the movement of the entity (6a, 6b) from one group (5a, 5b) to another, in order to generate a log; a group control unit (13) authorised and able to control the group data of each entity (6a, 6b); and alert means that can be triggered as a function of said controlled group data.
