DIGITAL CONTENT RETRIEVAL UTILIZING DISPERSED STORAGE

摘要

A method begins by a DS processing module, when operable within a computing device, causing the computing device to receive a request for retrieval of a set of encoded content data slices from a dispersed storage network (DSN) memory, wherein the request includes at least the identity of the set of encoded content data slices. The method continues by determining user access rights based on a content timestamp. The method continues by determining the current timestamp and whether user access rights compare favorably to the content timestamp and current timestamp or can be modified to be favorable. The method continues by retrieving encoded data slices from the DSN memory and decoding the encoded data slices utilizing an error coding dispersed storage function and in accordance with the read operational parameters producing the content and sending the content and/or the encoded data slices to the requester.

1. A method for execution by one or more processing modules of a dispersed storage network (DSN), the method comprises:
receiving a request from a requester for retrieval of content previously stored within a DSN memory, wherein the request includes at least the identity of sets of encoded data slices representing the content; determining user access rights associated with the request based on a comparison of one or more timestamps associated with a user to a timestamp of the requested content; when the user access rights compare favorably, retrieving the sets of encoded data slices from the DSN memory and decoding the encoded data slices utilizing an error coding dispersed storage function to produce the content; and sending the content to the requester.
