DC CAFCFirst Claim
1. A method comprising:
- receiving a digital signal in a system including at least one processor;
selecting, using said at least one processor, at least one signal characteristic of the digital signal;
manipulating, using said at least one processor, the at least one signal characteristic to degrade the digital signal;
associating, using said at least one processor, at least one digital watermark with the degraded digital 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. The additional steps of descrambling and decoding may be performed until a predetermined condition is met. The predetermined condition may include, for example, reaching a desired signal quality of the data object.
