This procedure is a software lock which prevents system access or tampering. This is accomplished by encrypting the user identification (ID) and password (PW) information in an internal list of a compiled program. This User ID/Password program is self-compiling, leaving no user readable source code on the system. After compilation, the object code, which is readable only by the computer, is all that remains. The program has been fully tested on a graphics system and proved to be fully functional. Other versions of User ID/Password programs decode external files, sometimes accessible to the user, containing User IDs and Passwords. These procedures are cumbersome, hard to modify, and usually take several minutes to decode, depending on the number of users. The new program takes an average of 3 seconds for full execution.
