%0 Patent %D 2010 %T Data hiding in compiled program binaries for supplementing computer functionality %A M. Wu %A Swaminathan,Ashwin %A Mao,Yinian %E University of Maryland %X Bit reductions in program instructions are achieved by determining the set of bit patterns in bit locations of the instructions. If only a subset of bit patterns is present in the instructions, they may be represented by an index value having a smaller number of bits. The index value may be substituted into the instruction and later used in decoding by referencing a corresponding bit pattern in a lookup table. The bit-reduction in the instruction makes way for supplemental data bits which may then be embedded. %V 11/445,374 %8 2010/11/23/ %G eng %U http://www.google.com/patents?id=tNHbAAAAEBAJ %N 7840789
