A method for encryption, storage, decryption, and retrieval of encrypted data operates on the computer system (20), which also includes an information database (62) and a key database (44). The key database (44) is isolated from the information database (62). The security domain (22) includes a system key manager (84) operable to generate system keys with system key common names and an encryption key manager (24) operable to generate encryption keys having encryption key identifications. The key managers (24, 84) operate on a key server (40), which is mirrored by a secondary key server (42). A general security manager (82) also operates on the key server (40) to control access to the security domain (22). The security information attribute (32) is stored with a persistent data entity (30A) that is associated with the other data entities (30C, 30D) by a database schema. The security information attribute (32) includes the encryption key identification (112) for the encryption key used to encrypt the data entities (30C, 30D). The encryption key identification is encrypted by the system key, and the system key common name hash value (114) is also stored in the security information attribute (32).

Title: Method and apparatus for extracting a signal identifier, method and apparatus for creating a database from signal identifiers, and method and apparatus for referencing a search time signal
Inventor: KLEFENZ FRANK
IPC: G10L25/81
Filed: 2002-03-12
Abstract: The invention relates to a method for extracting a signal identifier from a time signal, according to which the temporal occurrence of signal edges is detected in the time signal (12), whereby a signal edge has a specified temporal length. In addition, the temporal interval between two selected detected signal edges is determined (14). A frequency value is calculated (16) from said determined interval and is assigned to a time of occurrence of the frequency value in the time signal in order to obtain a co-ordinate tuple from the frequency value and the time of occurrence for said frequency value. A  signal identifier is created from a plurality of co-ordinate tuples (18), each co-ordinate tuple containing a frequency value and a time of occurrence, in such a way that the signal identifier comprises a sequence of signal identifier values, which reproduce the temporal course of the time signal. The extracted signal identifier is based on signal edges of the time signal and reproduces the temporal course of the time signal. The signal identifier thus characterises the time signal and is stable in relation to changes to said time signal.
