Claim Text:
1. A method for determining an identifier for a segment of a document, the method comprising: sequentially processing the individual elements of the segment in a plurality of memories comprising a shift register, a first memory and a last memory; subdividing the segment into a number of portions equal to a number of individual elements in the segment plus one; storing the individual elements in the plurality of memories by shifting the elements from the first memory to the last memory, when an index of the individual element in the last memory is less than or equal to a first result multiplied by a second result, the first result being equal to an index of an individual element currently being processed divided by the number of portions, the second result being equal to the number of portions divided by two; extracting from the plurality of memories an individual element from the segment that is most centrally positioned between a first individual element and a last individual element of the segment; and assigning the most centrally positioned individual element of the segment as the identifier of the segment.
