  • METHODS, SYSTEMS AND COMPUTER-READABLE MEDIA FOR COMPRESSING DATA
    Publication number: 20070139227
    Abstract: An approach is described for the compression of input data, and particularly one which is suited for providing a lossless method for compressing random input data. Both a compression algorithm is described, as well as a decompression algorithm for restoring the original uncompressed data. The decompression algorithm allows for its parameters to be adjusted to suit one's needs as they relate, for example, to the ratio of compression as a function of the decompression speed.

  • Methods for categorizing input data
    Publication number: 20070116267
    Abstract: Methods are provided for categorizing input data into a selected data type category. Exemplary embodiments are directed to the categorization of binary input data, for example random input data, as either compressed or encrypted based on statistical analysis. To this end, at least a portion of the input data is analyzed to derive a statistical test result for the portion that is indicative of a degree of randomness of the data. The data is then categorized as either compressed or encrypted based on the statistical test result.
