|A Logistics Privacy Protection System Based on Quick-Response Barcodes Steganography
|With the continuous development of the logistics industry, express delivery has played an important role in society. Businesses and individuals can easily send and receive items through express delivery. In the process of express delivery, QR code is usually used as express labels to transmit express information. However, unprotected express labels may lead to the leakage of user privacy. Aiming at protecting the leakage of companies and personal privacy in the current logistics system, we propose and implement a logistics privacy protection system based on QR code steganography and multi-level encryption. Without changing the QR code scanning results, the system uses the error correction capability of the QR code to realize the steganography of encrypted data into the logistics QR code. The proposed system uses the AES algorithm as the encryption algorithm for private information, and the MD5 hash algorithm as the key derivation algorithm to achieve multi-level encryption and restricted privacy access rights; the RSA algorithm is used to ensure that the encrypted key can only be decrypted by the recipient. The QR code that hides the encrypted data is almost the same as the original QR code and the decoded result is the same, which effectively protects the privacy of the recipient/sender from the user’s perspective and hides the existence of steganographic data. As far as we know, this is the first effective solution designed for companies that require high privacy and confidentiality to protect their sensitive logistics information. The experiments demonstrate the effectiveness of the proposed system in logistics privacy information protection. The capacity experiment shows that our system can accommodate up to 9720 bits of secret data, and the robustness experiment shows that the steganographic QR code is robust against different physical noises (e.g., natural texture, angle, and distance). To promote the development of express logistics privacy protection, we release the source code of our program on Gitee.
