For this reason, the misuse of financial data has increased, leading to extensive research on the secure storage, sharing, and exchange of data. One of the methodologies used in this field is blockchain. To effectively combat these risks, businesses are turning to innovative solutions such as blockchain technology and digital signatures. These advanced technologies provide strong transaction authentication and provide enhanced defense. Digital signatures and blockchain technology work together to increase the security and reliability of digital transactions. Blockchain provides essential elements such as transparency, immutability, and consensus, while digital signatures work to verify authenticity and integrity. Combining these two powerful tools creates a robust solution that creates secure and reliable digital interactions that minimize the risk of fraud and foster trust in the digital ecosystem. This paper explores digital signatures and blockchain technology and explore how they can help improve security. In this study, we have designed a model based on blockchain and digital signature to improve data security by examining existing system models and data exchange security methods. Finally, this research has improved blockchain security for the transfer of financial documents.</p> https://journals.kmanpub.com/index.php/aitechbesosci/article/download/3124/4560
