Encryption and compression are different. Mathematically, it seems there is no way to make compressed versions of data equally amenable to transformations as uncompressed versions (without making many of those transformations very expensive, and essentially requiring decompression and recompression)....
But if there are specific transformations that interest you, you could maybe design a compression algorithm so that *those* specific transformations are efficiently do-able on the compressed data... -- Ben G On Sun, Nov 30, 2014 at 9:31 AM, Jim Bromer via AGI <[email protected]> wrote: > Well maybe compression systems just have to be designed so that > transformation functions can be applied without decompressing the > data.
