Fast pattern matching for compressed data get more important as the compressed data size gets lager. It also improves dependability of the compressed data by providing fast virus scanning for the compressed data. Compressed Pattern Matching, or CPM, is a class of fast pattern matching method and is executed without initial decompression of the compressed data. CPM for PPM compression, which is based on context matching and achieves good compression ratio, however, has not been proposed yet. This paper proposed CPM for PPM compression. The proposed method adds information on tree structure which is constructed in compression to the compressed data. CPM is executed by scanning the additional information. Computer simulation says that proposed method requires 0.12% – 5% file size overhead for half of the sample files. |
