emit... I was just reading the new patent app. It's completely different than Henson's. e.Digital is totally leaning on the ability of it's patented data segment structure. The main focus is to leave the storage media....ie: HDD....in its normal state....without any hardware modification at all. The patent surrounds..."10 digital storage security module" One component is the heart of it....along with a predetermined file format and modified bit stream for the files that are to be secured. Time period file existence can also be predetermined....utilizing clock. IMO...this process does not have to be specific to a PED device....it could be an expansion card for a PC.STB....or what ever. It's an open system.....leaning on their data segment ability. "[0019] A digital storage security module 10 can be placed between the media bridge 108 and the digital storage medium 114 to provide secure access to the digital media files. The digital storage security module can secure a data stream that includes the digital media files and digital storage medium format information before it is stored on the digital storage medium. Interfacing with the media bridge 108 or media processor 116 can require that transferred data to or from the digital storage medium be preceded by commands. The digital storage medium, being an unsecured device, is not able to process commands that have been secured. The digital storage security module can be configured to monitor the data stream and distinguish commands from data; leaving hardware commands unsecured while securing the data. For example, if the digital storage medium is an ATA hard drive, the digital storage security module can leave the commands necessary to operate the ATA hard drive unsecured. By Securing only the data, and not the commands to the digital storage medium, the digital storage security module can enable the digital media files and format information to be securely stored on the digital storage medium without requiring specialized chips to send, receive, and store the secured data." doni
