System and methods for permitting open access to data objects and for securing data within the data objects
First Claim
1. A method for streaming media over a network, comprising:
- receiving in a first device an openly accessible data object comprising digital data and file format information;
said first device embedding independent data into the openly accessible data object and then scrambling the openly accessible data object to perceptibly degrade the openly accessible data object to a predetermined signal quality level where at least a portion of the independent data can be decoded from the scrambled openly accessible data object;
said first device repeatedly performing the steps of embedding and scrambling until a predetermined condition is met wherein the predetermined condition comprises reaching a desired signal quality level of the openly accessible data object, the repeated steps resulting in generation of an openly accessible data object having the desired signal quality;
said first device transmitting said openly accessible data object having the desired signal quality over a network;
a second device receiving over the network a signal stream comprising the said openly accessible data object having the desired signal quality;
said second device receiving a first key;
said second device applying 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
said second device generating at least one of an audible and a visual signal, based upon said signal stream descrambling algorithm output signal.

Abstract
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.
