Abstract
Embodiments of a system and method for detecting a security compromise on a device are described. Embodiments may be implemented by a content consumption application configured to protect content decryption keys on a device, such as a computer system (e.g., a desktop or notebook computer) or a mobile device (e.g., a smartphone or tablet). For instance, the content consumption application may be configured to provide decryption keys for respective content to a media component (or another component of the operating system) if multiple conditions have been met. For instance, in various embodiments, the content consumption application may pass the key to the media component after ensuring that i) one or more security mechanisms of the device operating system have not been compromised and ii) one or more executable instructions of the content consumption application have not been tampered (e.g., instructions corresponding to a function that handles the decryption key(s)).
