.~ Digital data (e.g., software program protection, data encryption)
DEFINITION
Classification: 380/4
Digital data (e.g., software program protection, data encryption):
(under subclass 3) Subject matter which prevents duplication of, or unauthorized access to, information stored as a group of discrete pulses.
(1) Note. Such information often includes a set of programmed instruction for computing equipment.
(2) Note. For classification herein encryption of data or instructions is required. Data or program protection using an instruction, such as a control signal which deletes data or disables a recording or control function, is not classified herein, but rather in the appropriate storage or computing equipment class.
