Digital content distribution and subscription system

摘要

Digital content distribution systems and methods are provided for distributing for digital data files, such as digital audio and video data files. In accordance with one implementation, a token-based authentication system is provided that does not require knowledge of the individual user requesting the download of digital content data or real-time access to user account information. Instead, the token-based authentication system embeds the authentication information, or token, in the download request information itself. In this way, the download or content server authenticates the download request using the token contained in the download request information and therefore does not require any additional information to carry out this authentication, such as access to user account information.

主权项

1. A token-based system for distributing digital content, the token-based system comprising:
a memory device that stores a set of instructions; at least one processor that executes the set of instructions; a token generator, executing on the at least one processor, that generates a plurality of tokens and distributes the tokens to one or more servers, the tokens including a first token and a second token; an application server that; receives the second token distributed by the token generator, encodes the second token, generates, in response to a first download request for digital content from a client, a download address of the digital content using the encoded second token and at least one of a content file name or content identifier, and provides the download address to the client; and a content server that:
receives the first token distributed by the token generator,encodes the first token,receives, from the client, a second download request including the download address,extracts the encoded second token from the received download address, andauthenticates the second download request by comparing the encoded first token with the encoded second token.
