Abstract
In today's digitized world, the verification and authentication of documents play a pivotal role in safeguarding financial transactions, legal agreements, and personal identities. This research paper presents a comprehensive review of existing document verification techniques, their challenges, and practical implementations across diverse domains. The paper surveys techniques such as signature verification, stamp verification, image processing, and machine learning, all designed to ensure the authenticity and integrity of documents. Document verification systems face various real-world challenges, including scalability, accuracy, and security concerns. These challenges are explored in depth, shedding light on the limitations and opportunities for improvement. The paper further investigates practical implementations of document verification methods in sectors ranging from financial institutions to legal practices and identity verification systems, evaluating their effectiveness in reducing fraud, minimizing errors, and enhancing operational efficiency. Moreover, the paper discusses the potential for integration, proposing a unified document verification framework that accommodates both electronic and printed documents. This framework aims to provide robust document authenticity, integrity, and non-repudiation across multiple applications. By synthesizing the wealth of knowledge and experience in document verification, this research paper serves as a valuable resource for practitioners and researchers seeking insights into document security and authentication. It offers a holistic view of the field, highlighting areas ripe for advancement and offering practical guidance for improving document verification systems in the digital age.
