Abstract

Disclosed is the writing of a system-unique identification sequence, such as the serial number of a system, into the header information of a file written by the system to a storage device. This method can be used to identify the source for files, whether limited to data or containing executable code, stored in diskette drives, optical drives, and hardfiles with removable or non-removable media. The serial number or other identifier can be obtained from the Vital Product Data (VPD) area of the system. This method can be applied to a variety of information processing devices, such as computers, word processors, hand held data organizers, banking systems, and intelligent appliances.

Method for Tracking Programs and Data Storage Media

      Disclosed is the writing of a system-unique identification
sequence, such as the serial number of a system, into the header
information of a file written by the system to a storage device.
This method can be used to identify the source for files, whether
limited to data or containing executable code, stored in diskette
drives, optical drives, and hardfiles with removable or non-removable
media.  The serial number or other identifier can be obtained from
the Vital Product Data (VPD) area of the system.  This method can be
applied to a variety of information processing devices, such as
computers, word processors, hand held data organizers, banking
systems, and intelligent appliances.

      When a file is transmitted by means of a Local Area Network
(LAN), SCSI bus, cellular telephone system, modem, or similar method,
the header information of the file contains the identifier of the
system which originated the file.  When a system formats removable
media, such as a diskette, the system writes its identifier onto the
header of the formatted diskette.  Whenever a system writes to a
storage device, the system writes its identifier in the area
containing the file directory.  This can be done, for example, in the
File Allocation Table (FAT) of the storage device.  Furthermore,
additional fields in the file directory  may be allocated for the
identification number of the system which first created the file, of
the system which...
