1. A computer-implemented method of determining the resemblance of a plurality of data objects, comprising the steps of: parsing each data object into a canonical sequence of tokens; grouping overlapping sequences of the tokens of each data object into shingles; assigning a unique identification element to each shingle; permuting the elements of the data objects to form image sets; selecting a predetermined number of minimum elements from each image to form a sketch; partitioning the selected elements of each sketch into a plurality of groups; and assigning another unique identification to each group to generate the features of each data object to determine a level of resemblance of the plurality of data objects.
