Abstract: An embodiment of the invention describes a method for detecting tampering with copy restrictions on a media playback device that includes identifying locations within playback application executable files on a playback device that contain instructions for application programming interface (API) calls, modifying the API call locations to insert pieces of tamper detection code, where the pieces of tamper detection code when executed collects monitoring data about characteristics of the playback device and content being played, collecting monitoring data when API calls are performed by the API call locations, generating a confidence level of tampering from the collected monitoring data, and performing a remediation action in response to the confidence level exceeding a predetermined threshold, where the predetermined threshold is set based on types of monitoring data that was collected.

Abstract: An approach for protecting digital contents includes a content delivery phase wherein a client stores digital contents or retrieves them in streaming, transmits to a user device the digital content in a protected format along with an enabling code for enabling the user device to access or read the protected digital content. The approach includes a key generation phase in a DRM (Digital Right Management) server which derives at least one key for encrypting the digital contents. A key transmission phase involves the derived key being transmitted from the DRM server to the client. For decrypting the digital content, the user device requests the key from the DRM server, with the request including a key identification defined by the enabling code transmitted by the client to the user device which is used by the DRM server to derive the key for the user device.

Abstract: The invention relates to a method of treating a mixture (5) containing at least one ester compound having at least one ester bond, in order to enable a dissociation of the ester bond and a re-esterification of the ester compound. The invention also relates to a chemical processing equipment (1) and a mixture (5) containing an ester compound.
