This article describes a software method for restricting access to software other than in association with specific hardware. This protection is achieved without use of special hardware. When providing both hardware and software to access a particular data base, it is desirable to ensure that the software is used on the provided hardware and not taken to another system. Existing schemes provide a hardware feature that can be interrogated by the host for this purpose. In the method disclosed herein each user of the data base has an identification and probably a password, to establish connection to the host. These can be transported to another system. The protection mechanism has a special location in the program file that contains an additional access code. This code is not known by the user, only by the host program.
