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.
