After twenty years, a vulnerability in Lempel-Ziv-Oberhumer (LZO), an extremely efficient compression algorithm, has finally been patched. The flaw, a subtle integer overflow, existed for as long as ...

All compression algorithms utilize two basic functions. The first removes redundant or irrelevant information. Redundancy removal can be lossless or lossy. The second function, bit packing, packs the ...

When designers talk about data compression these days, typically they are thinking about highly-evolved lossy compression algorithms for particular media data types: MP-3 for audio, for example, or ...
