Abstract:
A method of detecting the likelihood of the presence of any of a first set of known data traits in a data string, by use of a second set G of generic features and a third set S of signatures, wherein the generic features and the signatures are characteristic of said first set of data traits, said method comprising the steps of:a) loading the set G into a memory of a computer,b) locating occurrences within the data string of each generic feature in said set G,c) applying a first mapping from the occurrences located during step b) to obtain a subset S* of S,d) loading all signatures from the subset S* into a memory of said computer,e) locating occurrences within said data string of all signatures from the subset S*, andf) applying a second mapping from the occurrences located during step e) to identify a set of data traits that are likely to be present in the data string.
