A copy-resistant read-only digital optical disc having encrypted digital data. The copy-resistant read-only digital optical disc includes a digital work, a variable user data format encoding said digital work after encryption with a variable software algorithm, an implementation of said variable software algorithm, and an implementation of said variable user data format encoded in a default format. The encrypted digital data is read on an adaptable digital optical disc player, which is adaptable to a user data format described on said copy-resistant read-only digital optical disc made in accordance with this invention. A copy-resistant read-only digital optical disc made in accordance with this invention will provide necessary user data format information on the disc in a default format, which is always accessible by an adaptable player.

The user circles the fax number or name of the receiving party and the system then uses the circled number or name to dial the receiving party's fax machine to initiate the transmission. The system scans the first page or cover page of the document to be faxed and uses a computer-implemented algorithm to detect the user-circled region. The image within the user-circled region is then extracted and optical character recognition performed to ascertain the fax number. Alternatively, the user-circled region may contain a name or other information to access a database where the fax number is stored.
