Claim 16:
17. A method comprising:
transforming input data at inputs of a wavefront post-transform processor to output data at outputs of the wavefront post-transform processor using a wavefront post-processing transform;
dynamically connecting, based on an input mapping table configurable to change an input connection pattern, input streams to the inputs of the wavefront post-transform processor using an input switching circuit;
dynamically connecting, based on an output mapping table configurable to change an output connection pattern, the output data at the outputs of the wavefront post-transform processor to retrieval streams using an output switching circuit;
controlling, based on a wiping command, at least one of the input and output switching circuits to alter at least one of the input and output mapping tables such that the at least one of the input and output switching circuits is disabled for connection; and
controlling, based on a timing interval or a count for number of downloads by a user generated by a timer/counter, duration of availability of a known a priori backdoor data stream to the input switching circuit;
wherein a first subset of the input streams operates in a foreground mode available to the user and is retrieved from remote storage sites at a network and a second subset of the input streams operates in a background mode available to an administrator and is not retrieved from the remote storage sites.
