Classification: CPC G | IPC G

Claim 7:
8. An apparatus comprising:
a wavefront post-transform processor having inputs and outputs and configured to transform input data at the inputs to output data at the outputs using a wavefront post-processing transform;
an input switching circuit configured to dynamically connect, based on an input mapping table configurable to change an input connection pattern, input streams to the inputs of the wavefront post-transform processor;
an output switching circuit configured to dynamically connect, based on an output mapping table configurable to change an output connection pattern, the output data at the outputs to retrieval streams;
a controller configured to control, 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
a timer/counter coupled to the controller, configured to generate a timing interval or a count for number of downloads by a user, to control duration of availability of a known a priori backdoor data stream to the wavefront post-transform processor;
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.
