System and method for securely retrieving and playing digital media

摘要

A system for securely downloading and playing coherent digital content such as music and preventing its play by unauthorized users. The system may include mass server/storage devices for receiving and storing digital content having predetermined gaps; and client devices communicating with the server/storage devices, and providing authorization to proceed. During playing of the digital content by the client devices, the missing gaps may be filled into the appropriate places, to allow the play of the coherent digital content.

主权项

1. A method for securely playing coherent digital content and preventing its play by unauthorized users, the coherent digital content comprising extracted media content and incoherent digital content comprising segmented media content, comprising the steps of:
producing the segmented media content by first removing the extracted media content from the coherent digital content, leaving predetermined gaps in the segmented media content into which gaps audio distortion is inserted; upon the one or more client devices obtaining authorization of entitlement to receive the coherent digital content, temporarily returning and merging the extracted media content with the segmented media content using information comprising one or more reassembly algorithms, thereby instructing the merging of the extracted media content within the predetermined gaps of the segmented media content, and temporarily overwriting the audio distortion and enabling a temporary reconstitution of the extracted media content with the segmented media content to enable playing or execution of the reconstituted coherent digital content by the one or more authorized client devices, wherein the merger instructions are not contained in the extracted media content, and at least one of the extracted media content and the one or more reassembly algorithms do not remain permanently available to the one or more authorized client devices after playing or execution of the reconstituted coherent digital content.
