ABSTRACT:
The present invention provides for a method and system for providing a type of Managed/Secured File Transfer between one or more computers arraigned in server-client or peer-to-peer configuration. This method and system takes digital content in the form of a file, shreds this file into separate pieces and encrypts each piece separately. Once encrypted, each piece is stored into a database. Client applications can then access these pieces of digital content over a network, decrypt and reassemble each piece to be played in the case of audio/video content, or viewed in the case of visual content. In some embodiments, the content requested by the client application is stored into a second database in a shredded and encrypted format, whereas in other embodiments the content is reassembled into the original non-encrypted and non-shredded file format. This method and system can reside on a computer system, hand held device, or other device.
