A method of storing and retrieving a utilization data ((CC#) or applicative data for instance) associated to a sensitive information (CC#) which requires to be secured in an environment comprising a plurality of application systems (ASi i=1..n ) that can use said information (CC#), characterized in that storing said information (CC#) comprises the following steps:
€¢ at a given application system (AS j ) of said plurality of application systems (A8i ¡=1 .. n ): receiving said information (CC#) (21), generating from said information (CC#) an extracted data (C(CC#)) and a complementary data (A(CC#)), generating an encoded information (H(CC#)) from said information (CC#), sending the extracted data (C(CC#)) and the encoded information (H(CC#)) to a server system (SS) (22),
€¢ at the server system (SS): generating an index (ID) and assigning this index (ID) to the encoded information (H(CC#)) and the extracted data (C(CC#)), storing the encoded information (H(CC#)), the extracted data (C(CC#)), and the index (ID) in a database (DB ss ) associated to the server system (SS) (23, 24), forwarding the index (ID) to the given application system (AS j ) of the plurality of application systems (A8i i=1 .. n ) (25),
€¢ at said given application system (AS j ): assigning the index (ID) to an application stored data (A(CC#), applicative data) related to the information (CC#), storing the index (ID) along with said application stored data (A(CC#), applicative data) in a database (DB ASj ) associated to said given application server (AS j ) (26). |
