Abstract
Generally, this disclosure provides systems, methods and computer readable media for secure sharing of user annotated subscription media content with trusted devices. The shared content may include user specified snapshots of the media along with user supplied annotations. The system may include a host processor configured to arrange a secure session with a server and to receive the subscription media content from the server in an encrypted format. The system may also include a trusted execution environment (TEE) comprising a secure processor and secure storage configured to decrypt and store the media content, based on a content encryption key obtained from the server. The system may further be configured to: receive a snapshot frame request and annotations from the user; generate a composite image of the snapshot and an overlay including the annotations; and encrypt the composite image for sharing with other users.
