Patent ID: 8769373

Claim:
A method of identifying and protecting the integrity of a set of source data, comprising the steps of: (a) passing the source data through a transformation utilizing at least one of an interleaver comprising a Forney interleaver, a 2-bit rotation, a criss-cross wiring matrix, a serial-to-parallel data converter whose output is interleaved by a criss-cross wiring matrix, a serial-to-parallel data converter whose output is interleaved by an M-by-N FLASH memory, parallel data lines input to an M-by-N FLASH whose output is interleaved by an M-by-N FLASH memory, an interleaver comprising a serial-to-parallel data converter whose output is interleaved by an M-by-N RAM memory, or parallel data lines input to an M-by-N RAM memory whose output is interleaved by an M-by-N RAM memory to produce a transformed set of source data, where m<n, m>n, or m=n; (b) distorting said transformed set of source data with a distortion function to produce an intermediate set of source data; and (c) passing the intermediate set of source data through an error detection and correction (EDAC) algorithm to produce a remainder and attaching said remainder to the set of source data to produce an encoded set of source data.
