英文摘要 | The development of the Internet has provided great convenience to people’s lives, but there are also many problems. Among them, the information security problem is particularly serious. As an important online and offline information communication medium in the Internet, Quick Response (QR) Code has also begun to stand out in the Internet field. This paper uses the combination of two-dimensional code and information hiding technology as the core of secure communication. This method makes use of the large amount of information encoded by the QR code and the high anti-fouling characteristic. Firstly, the secret message is encoded to improve the hidden capacity and the secret message is anti-offensive. Then, according to the image steganography technology of adjacent pixel to an absolute value (AVAP), the steganography of secret message is carried out by comparing with corresponding data bits to ensure the image quality. The experimental results show that compared with the existing LSB steganography methods, the steganographic images not only have better quality, but also have a higher payload. In addition, this method solves the security problem in the field of information hiding by implementing double encryption from the perspective of secret message and carrier. |
