摘要：These paper agreements with by the numbers,electronic being owner with the help of by numbers, electronicwatermarking getting fixed attack algorithm. For putting in anybeing owner information in any form inside the image oranything by which something is done like viewing part, audio,video etc, we need a by numbers, electronic watermarkinggetting fixed and extraction algorithm, so owner of the bynumbers, electronic purpose will be able to make out and putforwards as a fact his/her rights when any illegal person putforward as a fact his/her false rights on that purpose by gettingfrom the watermark. In this make observation paper ,we give acomparison between two watermarking algorithm based onDWT one on able to be put in addition getting fixed secretdesign so that substance mixed in algorithm and second one onmultiplicative getting fixed secret is MULTIPLICATIVEalgorithm. Being strong in limited stretch of time of GaussianNoise attack of both the algorithm & tested in terms of PSNRand SNR and compared
