Macrovision says it's acquiring BD+ technology from Cryptographic Research, Inc.
“We are a research organization dedicated to solving difficult cryptography problems,“ commented Paul Kocher, President and Chief Scientist of Cryptography Research Inc. “We developed SPDC to enable consumers to experience content across a broad range of devices while simultaneously providing content owners with the control to manage the security of content in this dynamic environment. Macrovision shares this goal and now that SPDC has entered commercialization, we are confident Macrovision will take it to the next level.”
Unlike previous DVD security technologies, a critical advantage of BD+ is its ability to respond dynamically to security threats. Similar to Macrovision’s ACP technology, BD+ resides both in devices and on the media. Title-specific security code is embedded in each BD+ protected disc. On the device side, BD+ utilizes an embedded virtual machine and APIs that are integrated directly into the media player, which communicate with the code from the discs. As a result, new titles can carry unique security code to address emerging threats, thus providing content producers the ability to respond to security breaches without impacting legitimate consumers.
