Secure Authentication via Encrypted QR Code

In this research study, a secure client-to-client communication system using QR code encryption and one-time passwords (OTPs) is introduced. The report discusses how modern applications are becoming more and more dependent on strong data security. The paper presents a thorough system architecture by investigating encryption methods, creating QR codes, and decryption procedures. The selection of encryption methods, key management techniques, and temporal and data integrity concerns are covered. The implementation and validation details offer valuable insights, and the advantages of the proposed method are emphasized by a comparative analysis with current systems. A discussion of possible uses and directions for further study rounds out the report.
