Signature is one of the characteristics of every person. Signatures are widely used as a condition for ratifying legal documents. This becomes problematic if a transaction is problematic or fails due to signature forgery, of course this is very detrimental, so it is very important to verify the signature. One way to be able to identify a match signature is by utilizing image processing techniques. To get the identification of the signature match, the RIPEMD160 method is used which prioritizes processing the Hash value of a digital image to provide special characteristics for a digital image data, and at the same time as a data that will be used as a verifier for the authenticity of digital image data by processing the signature image and provides information that only the original signature would have. The result of this process will indicate that a signature matches or does not match and can distinguish itself from a signature that has an original verification and is not.
