Abstract: Robust, computationally-efficient and secure systems, devices and automated processes are described for storing content on a disk drive or other storage device that is supplied to a media encoder or other host device. The user-supplied drive may be used, for example, to store content in a digital video recorder (DVR) or the like. The host device creates two separate digital identifiers that separately identify the host device and the user, respectively, so that subsequent pairing can be performed based upon either identifier. The two identifiers are stored on the storage device and rendered upon subsequent pairing for validation by the host device.

Abstract: Systems, devices and automated processes provide robust, computationally-efficient and secure protection of media content or other electronic data stored on a user-supplied storage device through the use of efficient file system encryption. Only certain portions of the content are encrypted by the host device, thereby reducing the computational demand in comparison to encrypting all of the content. By selecting the particular portions to encrypt, the formatting and structure of the stored data can be concealed, thereby making the use of the unencrypted content very difficult, if not impossible. In implementations based upon the XFS file system, for example, the superblocks that store header information about the files stored on the drive can be encrypted, thereby rendering the unencrypted content
