Abstract: In one example, the present disclosure describes a device, computer-readable medium, and method for multi-phase protection of digital content. For instance, in one example, a method includes receiving a request for digital content from a client device, initiating a digital content protection process comprising a plurality of phases, where each phase of the plurality of phases includes verifying credentials provided by the client device, delivering a plurality of seeds to the client device, wherein each individual seed of the plurality of seeds is delivered to the client device upon a successful completion of one phase of the plurality of phases, encrypting the digital content, using an encryption key derived using the plurality of seeds, to generate encrypted content, and delivering the encrypted content to the client device.

Abstract: Aspects of the subject disclosure may include, for example, a local server coupled to a plurality of client devices. The local server may receive encrypted content from one or more content sources and provide the content to the client devices. The local server and client devices may be part of a multi-client environment such as a hotel or conference center. The local server does not decrypt and re-encrypt content, thereby allowing the use of low cost equipment. Other embodiments are disclosed.
