Data medium for the control of entities, and device and method for the control of entities

Device (10) for controlling entities, comprising a plurality of data media (1), each data medium (1) comprising identity data relating to the entity (6a, 6b) to which it is assigned, said device (10) comprising control means (11, 13) equipped with at least one identity control unit (11) capable of accessing said identity data, characterized in that it comprises a plurality of data media (1) according to any one of the previous claims, at least one qualified updating unit (12) comprising at least one access key for said gate protecting access to said group data and capable of updating said group data 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 history being preserved by said group zone (4), in that said control means also comprise at least one qualified group control unit (13) comprising at least one access key for said gate protecting access to said group data and capable of accessing said group data of each entity (6a, 6b) and of controlling it, in that said device (10) comprises alert means coupled at least with said group control unit (13) and capable of triggering an alert on the basis of said group data controlled by said group control unit (13).

Method for controlling entities (6a, 6b) in which said entity (6a, 6b) is assigned at least one data medium comprising data relating to the identity of said entity (6a, 6b), characterized in that

• a 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 reserving said history;
• and
• a device (10) for controlling entities, comprising a plurality of data media (1), each data medium (1) comprising identity data relating to the entity (6a, 6b) to which it is assigned, said device (10) comprising control means (11, 13) equipped with at least one identity control unit (11) capable of accessing said identity data, characterized in that it comprises a plurality of data media (1) according to any one of the previous claims, at least one qualified updating unit (12) comprising at least one access key for said gate protecting access to said group data and capable of updating said group data 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 history being preserved by said group zone (4), in that said control means also comprise at least one qualified group control unit (13) comprising at least one access key for said gate protecting access to said group data and capable of accessing said group data of each entity (6a, 6b) and of controlling it, in that said device (10) comprises alert means coupled at least with said group control unit (13) and capable of triggering an alert on the basis of said group data controlled by said group control unit (13)
• are used, said method also comprising at least the following steps:
• the updating, recording and storage on said data medium (1) of group data relating to the change in group (5a, 5b) of said entity (6a, 6b), in order to create, by means of updates, a history of said groups (5a, 5b) to which said entity (6a, 6b) has belonged,
• the control and filtering of said group data of said entity (6a, 6b) in order to verify said history and, on the basis of said controlled group data, to validate said control or not.
