Cheque leaf authentication is a process of verifying the authenticity and validity of a cheque. Artificial intelligence can help to perform cheque leaf authentication by using various methods and techniques that can analyze and compare handwritten signatures. AI can use geometrical features, such as shape, size, angle, or curvature, to identify the signature and its variations. AI can also use machine learning models, such as neural networks, to learn from a large number of samples of genuine and forged signatures, and to detect any anomalies or discrepancies. By using AI, cheque leaf authentication can be improved and fraud can be prevented.
