Claims
Claim 120
In a digital computer system having digital data processing means for executing a plurality of digital computer programs for a computer user and memory means for storing digital program instructions and digital data, a method for providing improved computer security comprising the steps of:
a) storing digital authorization information in said memory means which restricts an associated program from accessing resources when executed by said digital data processing means which are accessible to said computer user; and
b) storing in at least one segment, digital data for associating said authorization information with at least one program to be executed by said processing means for said computer user.
