A Review: Safer Document Exchange Protecting Documents using OTP, Authentication, and QR Codes

Abstract—Sensitive document communication must be done securely in the digital age. Conventional approaches frequently fail to provide enough protection against tampering and un- wanted access. By combining One-Time Passwords (OTPs) with authentication methods and Quick Response (QR) codes, this article suggests an improved document protection solution. By using OTPs as a dynamic authentication factor, the suggested solution makes sure that every access request is verified with a distinct, time-sensitive code. The technique enables quick and easy authentication when combined with QR codes, which act as a secure connection between the user and the document. An OTP is generated when users use a mobile device to scan the QR code. Only those who are authorized can see or download the content because access to the document is allowed upon entering the OTP. This two-pronged strategy greatly reduces the chances of data breaches, phishing scams, and illegal access. Additionally, user experience is given top priority in the system’s design, which strikes a compromise between strong security features and usability. While OTPs offer an extra degree of protection, QR code integration streamlines the authentication procedure. This study shows how well OTPs and QR code- based authentication work together to improve document security through thorough analysis and application. The suggested system provides a scalable solution that may be applied to a variety of industries where document secrecy is essential, such as gov- ernment, healthcare, and finance. Organisations can strengthen their digital document exchange procedures against new security threats by implementing this integrated approach.
