The defect of existing similarity measure in fingerprinting (watermarking) extraction is discussed, by using the similarity measure, it is found that two obviously different fingerprint (watermark) can be determined to be approximate or the same. According to the defect, an improved similarity measure is presented. The difference and relation between two measures are discussed and the analytic expression for deriving one from the other is also presented.
