In the digital age, ensuring the authenticity and integrity of electronic documents is paramount. This paper presents a novel digital signature validation system integrating facial verification to prevent misuse and unauthorized access. The system leverages advanced cryptographic techniques to generate digital signature certificates, ensuring data integrity and non-repudiation. Existing digital signature solutions are often embedded in complex software or limited to blockchain-based document authorization within organizations. This solution introduces an openly available system with high usability, allowing integration with multiple document types and handling multiple signatories using a single SHA-256 hash code. Each signatory requires prior registration before being added to the signature certificate by the creator. Facial recognition technology further enhances security by verifying the signatory’s identity, mitigating the risk of forgery and unauthorized access. The signatory's live image is compared with stored biometric data for authentication. This integration of cryptographic security and biometric verification provides a comprehensive solution for secure digital transactions, making it ideal for finance, legal, and other high-security applications.
