Background of the technology

Certain forms of data storage, such as optical disk (CD/DVD/HDDVD and BD) or flash/RAM/ROM memory, may contain data, which is subject to copyright, and it is therefore desirable to prevent unauthorized copying of such data. The conventional data protection measures that are used to prevent unauthorized copying have been ineffective in combating this piracy.


One example of such conventional protection measures is to add a secure sector to the optical disc that cannot be copied by normal optical disk writers. This secure sector contains information that will enable the disk to be read. Thus, unless the secure sector is also copied to the new disc, the new disc cannot be read. This protection technique will only be effective as long as the secure sector is not rewritable by available CD or DVD copiers. Similar problems are encountered in protecting computer program instructions stored on other types of digital recording media.

Universal Data Protection Corporation’s patent pending technology for improved security of data storage and optical discs evolved from our microcontroller and microprocessor protection method.

Universal Data Protection Corporation (UDPi™) uses Double Axis Security™ and Stealth Data Delimiter™ technology for improving optical disc security.

The UDPi system requires that the hardware security be embedded in the processor during manufacturing. The reading device has one key (the microprocessor), the optical disc acts as the second key (the encoded data), and the third key is obtained when the unique reading device is matched with the unique optical disc. The UDPi process creates a “unique” identity for each individual optical disc and each individual reading device.

UDPi has created a consumer-friendly security technology, creating the opportunity to make back-up copies of optical discs and facilitates the use of multiple devices to play UDPi protected media. The goal of UDPi is not to prevent consumers from enjoying their various optical discs on all their reading devices, but is rather to prevent the mass distribution of copyrighted material.

Some other features of the UDPi solution for data piracy in data storage and optical discs include; low system overhead (no extra manufacturing costs), backwards compatibility for legacy optical discs, fast encryption/decryption, key time sensitive options (for rentals or other scenarios in which there is a desire to control the amount of time an optical disc can be accessed) and Active Consumers.

Applications: Software, Movies, Gaming Consoles, Hard-Drives, Flash Based Memory Sticks, Back-up Tapes, Audio CD’s, Portable Devices and many more.
