Claim 3:
4. The anomaly detection method according to claim 2, wherein
a Levenshtein distance between the plurality of detection target data is calculated for each pair of detection target data that are P data apart from each other in the detection target data stream, and the calculation is applied in units of Q bits to at least a portion of bit strings included in the data parts, wherein P is an integer greater than or equal to 1, wherein Q is an integer between 1 and 16, inclusive, and
in the calculating of the plurality of distances, a distance is calculated for each pair of the detection target packets that are P data apart from each other in the detection target data stream to calculate the plurality of distances.
