Embodiment Construction

[0047] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. The two-dimensional code secret sharing method based on visual password, its specific steps are described as follows figure 1 Shown in S1~S4. Wherein, the specific steps of the code word adjustment method based on visual password are described as follows: image 3 Shown:

[0048] Step 1: Read the carrier QR code C separately 1 ,C 2 ,...,C n information, and according to their version number and verification level, using the standard two-dimensional code coding process, through data analysis, data coding, redundant coding, code word filling and other operations, the M 1 , M 2 ,...,M n Content codeword.

[0049] In this embodiment, set n=10, 10 carrier two-dimensional codes and secret two-dimensional code images refer to figure 2 . Among them, the versions of 10 QR codes are all 4-H, and they contain meaningful content infor...

Abstract

The invention provides a QR code secret sharing method based on a visual password. The method comprises the steps: designing a 0-1 planning strategy by analyzing secret unrecoverable conditions of a shared subset, and then constructing a secret sharing matrix; based on the secret sharing matrix, adjusting the content code words of the carrier QR code by using an XOR visual password technology; andfinally, generating a secret sharing copy QR code according to the adjusted carrier QR code content code word, thereby realizing sharing of a secret QR code image. The method not only inherits the advantages of easy realization of visual cipher technology coding and low decoding calculation complexity, but also is superior to other existing methods in robustness, and the secret image has better security.

Description

technical field [0001] The invention belongs to the field of secret information sharing, and in particular relates to a two-dimension code secret sharing method based on a visual password. Background technique [0002] As the core sensing technology of the Internet of Things and an important information portal of the Internet, two-dimensional codes have gradually penetrated into various fields of my country's national economy and social life, becoming an important part of the country's real economy and an important strategic fulcrum for the competition of the global emerging information industry. However, with the rapid popularization of QR codes, security issues have become increasingly prominent, especially in the fields of O2O e-commerce and mobile payment. Since the two-dimensional code adopts the international common codec technology standard, criminals can easily steal the information in it when it is transmitted on an open channel or stored in an open network environm...
