Handwritten signatures serve as a well known way for identity verification, delivering distinctive biometric feature for personal identification. The complexity and variety of signatures offer substantial obstacles in attaining reliable verification. This work proposes a unique technique to handwritten signature substantiation using CNNs. The purpose is to harness authority of vast knowledge to boost accuracy & reliability of signature verification system. CNNs are used due to their amazing capabilities in image processing & feature extraction. Proposed system adopts a Siamese network design, comprised of twin CNNs sharing similar parameters. These twin networks are trained to extract relevant information from signature photos, learning to discriminate among legitimate & phony signature. The design incorporates many convolutional layers for feature extraction, pooling layers for dimensionality reduction, and dense layers for decision making. A distance metric, such as Euclidean distance, is employed to assess feature vectors created by the twin networks, yielding a similarity score that validates the legitimacy of the signatures.
