摘要：In the modern world of technology, Digital signature processing is most popular in the field of image forgery. We are using online signature recognition and verification technique of image forgery detection in which the signature is acquired from Digital signature pad or similar devices, and the image is compared to the signature which is already saved in the database, using various techniques. Signatures are of two types: Online and Offline. Now a day online signature is most frequently used technique in any era of signature recognition and verification, where image forgery is reduced and chances of malfunctions are less. We are preprocessing the signatures so it becomes easy to verify signature accurately at the end, in the same process it does the feature extraction by which signature is extracted in such a way that input signature will be in the easier form to be recognize. This paper verifies signature using pixel based approach in which the stored image and entered image are matched and if the matching factor is high enough or nearer to threshold value then the signature is accepted otherwise rejected.
