System and method for data compaction and security with extended functionality

A method for data conversion during decoding of data, comprising the steps of:

• receiving, at a computing device, training data for generation of a codebook;
• generating, using a codebook generator operating on the computing device, a codebook from the training data, the codebook comprising a plurality of sourceblocks;
• transmitting the codebook to a decoder operating on the same or a different computing device;
• receiving, at the decoder, encoded data which has been encoded into codeworks based on the codebook, each codeword referring to one of the sourceblocks in the codebook;
• decoding the encoded data using the codebook by identifying the sourceblock in the codebook to which each codeword of the encoded data refers;
• applying a rule to each sourceblock of the decoded data with which the rule is associated in the codebook to convert the sourceblock according to the rule;
• and
• outputting the decoded data as a sequence of its converted and unconverted sourceblocks.

A system for data conversion during decoding of data, comprising:

• a first computing device comprising a first processor and a first memory;
• a second computing device comprising a second processor and a second memory;
• a codebook generator comprising a first plurality of programming instructions stored in the first memory which, when operating on the first processor, causes the first computing device to:
• receive training data for generation of a codebook;
• generate a codebook from the training data, the codebook comprising a plurality of sourceblocks;
• transmit the codebook to a decoder operating on the second computing device;
• and
• the decoder operating comprising a second plurality of programming instructions stored in the second memory which, when operating on the second processor, causes the second computing device to:
• receive encoded data which has been encoded into codeworks based on the codebook, each codeword referring to one of the sourceblocks in the codebook;
• decode the encoded data using the codebook by identifying the sourceblock in the codebook to which each codeword of the encoded data refers;
• apply a rule to each sourceblock of the decoded data with which the rule is associated in the codebook to convert the sourceblock according to the rule;
• and
• output the decoded data as a sequence of its converted and unconverted sourceblocks.
