System and methods for permitting open access to data objects and for securing data within the data objects

摘要

A system and methods for permitting open access to data objects and for securing data within the data objects is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. The method includes the steps of (1) providing a data object comprising digital data and file format information; (2) embedding independent data into a data object; and (3) scrambling the data object to degrade the data object to a predetermined signal quality level. The steps of embedding and scrambling may be performed until a predetermined condition is met. The method may also include the steps of descrambling the data object to upgrade the data object to a predetermined signal quality level, and decoding the embedded independent data.

主权项

1. A method for using a device to render content to provide at least one of an audible and visual signal for perception by a person, comprising:
receiving in said device a signal stream comprising content in which the content in said signal stream is scrambled; receiving in said device a first key; applying, in said device a key based descrambling algorithm which takes as inputs at least one key and a signal stream and produces as output a descrambling algorithm output signal, to said first key and said signal stream, to produce a signal stream descrambling algorithm output signal; and generating, in said device, at least one of an audible and a visual signal, based upon said signal stream descrambling algorithm output signal.
