Copy-Protection Mechanism Using ID Number On Diskette

      Disclosed is a method to protect program diskettes from illegal
reproduction.  This method is implemented based on ID numbers
assigned to diskettes.  For example, volume-serial numbers on
diskettes.

Three mechanisms described below consists of the following:
  o  Program Diskette Generator
  o  Protected Program Installer
  o  ID Verifier
  1.  Program Diskette Generator - This is a mechanism to copy a
       program product into a target diskette, and write an ID number
of
       the diskette into a specific area of the program product.  ID
       number written in the specific area of the program product is
       called Program ID.  Using this mechanism, Program ID is
identical
       to ID number assigned to the diskette.
  2.  Protected Program Installer - This is a mechanism to install
the
       program product into a hard disk of a target computer.  This
       mechanism writes an ID number of the target computer into the
       specific area of the program product in the diskette, and
       installs the program product into the target computer.  This
       mechanism alters the ID number of the diskette after
       installation.  Using this mechanism, Program ID in the
diskette,
       Program ID installed in the target computer, and the ID number
of
       the target computer are identical after installati...
