Denuvo
Denuvo Anti-Tamper, or Denuvo, is an anti-tamper technology developed by Denuvo Software Solutions GmbH, a company formed through the management buyout (MBO) of Sony DADC DigitalWorks. The technology, although not a digital rights management (DRM) solution, is designed to slow down attacks on DRM, such as Origin and Steam.
==Technology==
Early reports suggested that Denuvo Anti-Tamper "continuously encrypts and decrypts itself so that it is impossible to crack."〔 Denuvo Software Solutions has stated that the technology "does not continuously encrypt and decrypt any data on storage media. To do so would be of no benefit in terms of security or performance." The company has not revealed how Denuvo Anti-Tamper works.〔 An independent Chinese warez group known as 3DM claimed to have defeated Denuvo Anti-Tamper on December 1, 2014. The group suggested that the technology involves a "64-bit encryption machine" that requires cryptographic keys unique to the specific hardware of each installed system. Later, in early December, the same group released a crack for the video game ''Dragon Age: Inquisition'', which uses Denuvo Anti-Tamper to protect Electronic Arts' Origin Online Access DRM. Asked about the development, Denuvo acknowledged that "every protected game eventually gets cracked".〔
