> Technological Protection Measures (TPMs) (also known as copy protection measures or DRM) are often used to protect copyright works, for example, through encryption on DVDs. TPMs can have a important role in enabling copyright owners (rightsholders) to offer content to consumers in different ways, as well as protecting against unlawful copying (piracy). UK law protects the right of copyright owners to use TPMs to protect their works, and circumvention of such technology is illegal.
