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

A method for using a device to render content to provide at least one of an audible signal and a 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;
• applying, in said device, to said signal stream and a first key, a first algorithm to produce a first algorithm output;
• applying, in said device, to said first algorithm output and at least one second key, a second algorithm to produce a second algorithm output which is unscrambled;
• generating, in said device, at least one of an audible signal and a visual signal, from said second algorithm output.

A device for rendering content to provide at least one of an audible and a visual signal for perception by a person, comprising:

• said device structured to receive a signal stream comprising content in which the content in said signal stream is scrambled;
• said device, designed to apply to said signal stream and a first key, a first algorithm to produce a first algorithm output;
• said device designed to apply to said first algorithm output and at least one second key, a second algorithm to produce a second algorithm output which is unscrambled;
• said device comprising a transducer for generating at least one of an audible and a visual signal, from said second algorithm output.
