The VeriTOC family of patents covers "shift key-immune" protection, authentication,
fingerprinting and selective enablement of music CDs
Macrovision launched a comprehensive licensing program for its VeriTOC worldwide patent
family for music CDs. The VeriTOC family is comprised of 23 worldwide patents, many
obtained from and developed after Macrovision`s acquisitions of MidBar Tech (1998) Ltd. and
TTR Technologies, Ltd.
The term "passive" refers to the fact that these technologies are embedded in the optical
media, and do not involve installed software on an end-user`s PC to produce their desired
Licensing the VeriTOC worldwide patent family allows content owners, independent software
vendors, content-protection providers and optical media manufacturers to (1) offer music CD
fingerprinting; original-disc authentication; personal computer "shift key-immune" music
content protection; and secure pass-through access to original CD content, and (2) embed
these technologies onto the optical media of music CDs. Macrovision believes that
comprehensive licensing of its VeriTOC worldwide patent family will accelerate adoption and
development of these music CD technologies.
Macrovision`s market-leading CDS-300 CD content protection product employs technologies
derived from patents found in the VeriTOC family, which have been applied to over 450 million
commercially released CDs.
