Information Encryption Mechanism Based on QR Code

With the rapid development of Internet of things technology, more and more attention has been paid to the security protection of personal information. This paper proposes an information encryption mechanism based on QR code to solve the problem of information leakage in data communication. The error correction mechanism of the QR code allows it to record information normally even if it is partially damaged. Taking advantage of this feature, this paper records secret information by changing limited data bits without destroying the original QR code. In addition, the secret sharing algorithm is introduced in this paper to divide the secret information into multiple parts for storage and transmission, and the original secret information can only be reproduced when all the information fragments are collected, further enhancing the security of information transmission. By combining the error correctionmechanism of the QR code with the secret sharing algorithm, the secret information can be transmitted safely. The encryption mechanism can effectively reduce the suspicion of the attacker on the secret information, and has the advantages of large storage capacity and flexible storage.
