Handwritten Signature Verification with Neural Networks. We've created a framework to identify Handwritten Signature fraud in checks and contracts in which, after being scanned, they can automatically be standardized and inserted into an algorithm that would verify if the analyzed document is authentic or a fraud Abstract Handwritten signatures are very important in our social and legal life for verification and authentication. A signature can be accepted only if it is from the intended person. The probability of two signatures made by the same person being the same is very less. Many properties of the signature may vary even when two signatures are made by the same person. So, detecting a forgery.
