US Patent 9626493 Continuous digital content protection

Data from one or more sensors of a computing device can be employed to provide continuous protection of digital content. After user authentication and authorization, sensor data can be utilized to control access to protected content. More specifically, sensor data can be employed as a basis for initially providing an authorized user access to protected content and subsequently terminating access to the protected content. For additional security, content can be embedded with user identifying information in the form of a watermark. Further, such user identifying information can be provided to a content owner identifying one or more users who viewed the content.
