Methods, Devices, and Systems for Preventing Rendering Content from CDN to Unauthorized Users

Techniques for preventing rendering content from content delivery network (CDN) to unauthorized users are described herein. In accordance with various embodiments, a CDN includes one or more processors and a non-transitory memory. The CDN receives a request from a client device for a media content item, where the request indicates an identifier of a client. The CDN further provisions an encrypted media content item corresponding to the media content item for the client, where at least a portion of the encrypted media content item is encrypted using at least one personalized key assigned to the client. The CDN also facilitates obtaining a manifest corresponding to the encrypted media content item, where the manifest specifies encryption metadata for retrieving the at least one personalized key by the client. The CDN additionally sends the encrypted media content item and the manifest to the client device.
