All datasare stored individually, in Individual Data Blocks : the IDBs. IDBs are NOT organized in records nor files.
An IDBis anonymous, encrypted and electronically signed (and includes the signature of his author).
An IDBincludes a parametered descriptor, used for statistical analysis and to determine who may access to the IDB.This descriptor contains informations about the date of creation, the author and a key that guarantees the integrity of the IDB and of his header. It can indicate the "place" of the data of the IDB in a more complex structure, such as a medical record.
An IDBincludes a « FASE » electronic key computed with the electronic identifier of his owner . This key permits to link the IDB with his owner.
It is impossibleto include an IDB in a FASE ODB if a smartcard is not present, because the smartcard is used to calculate the header of the IDB, the FASE descriptor and key and the address of the IDB in the ODB.
