Method and system for secure network-based distribution of content

A system comprising:

• a memory;
• and
• a processing system, operatively coupled to the memory, to:
• receive, from a client device, a selection of a media file from a plurality of media files;
• identify a user key associated with a user of the client device;
• generate a random content key;
• encrypt the media file using the random content key;
• encrypt the random content key using the identified user key;
• modify the encrypted media file to include a reference to the identified user key and the encrypted random content key;
• and
• transmit the modified encrypted media file comprising the reference to the identified user key and the encrypted random content key to the client device.

A method comprising:

• receiving, from a client device, a selection of a media file from a plurality of media files;
• identifying a user key associated with a user of the client device;
• generating a random content key;
• encrypting the media file using the random content key;
• encrypting the random content key using the identified user key;
• modifying, by a processing system, the encrypted media file to include a reference to the identified user key and the encrypted random content key;
• and
• transmitting the modified encrypted media file comprising the reference to the identified user key and the encrypted random content key to the client device.

A non-transitory computer readable medium including one or more sequences of instructions which, when executed by a processing system of a computing device, cause the computing device to:

• receive, from a client device, a selection of a media file from a plurality of media files;
• identify a user key associated with a user of the client device;
• generate a random content key;
• encrypt the media file using the random content key;
• encrypt the random content key using the identified user key;
• modify the encrypted media file to include a reference to the identified user key and the encrypted random content key;
• and
• transmit the modified encrypted media file comprising the reference to the identified user key and the encrypted random content key to the client device.
