Mobile phone two-dimensional code safe use method based on information hiding

Abstract

The invention discloses a mobile phone two-dimensional code safe use method based on information hiding. With the development of information technology and Internet technology, people pay more attention to the convenient and environmental-friendly two-dimensional code technology, and the use of the two-dimensional code is wider and wider. However, a traditional mobile phone two-dimensional code is lack of a necessary security mechanism, people can use a two-dimensional code as long as the people have the two-dimensional code, and the security of the private information of the user is invaded. The method is based on the information hiding technology, the cryptography theory and bar code technology are utilized, through a method of embedding user secret information in encoding and carrying out extraction, operation and comparison in decoding, the safe use problem of the mobile phone two-dimensional code is solved, the leakage and stealing of the information are prevented, and the integrity and confidentiality of the information are ensured. The method is simple and practical, with the gradual popularization of the Internet technology at the present age, and method plays an important role for the security of the information.

Description

technical field [0001] The invention belongs to the intersecting field of Internet of Things technology and information security technology. Involving information hiding technology, cryptography theory and barcode technology, it mainly solves the problem of safe use of mobile phone QR codes, and plays an important role in information security in the era when Internet of Things technology is gradually popularized. [0002] Background technique [0003] In the era of information technology, new technologies and new equipment allow information to be expressed in various forms, and the carrier of information is also changing. The two-dimensional code technology that was born a long time ago has "blossomed" in various fields in recent years. Two-dimensional code is a new generation of barcode technology that records data symbol information in a black and white rectangular matrix distributed on a plane (two-dimensional direction) according to certain rules. It consists of a two-d...

Problems solved by technology

[0006] However, while mobile phone QR codes give us convenience, they are not all advantages and no disadvantages.

The first is the issue of information leakage

QR codes have the characteristics of a large amount of information, but this is a double-edged sword. While we can obtain more information through QR codes, it is also possible that our personal information will be leaked because of this small QR code.

In the application of these two-dimensional codes, mobile phones that can receive multimedia messages can receive the two-dimensional code. At this time, if the multimedia message is forwarded by criminals, criminals can also use the two-dimensional code to steal other people's identities to board the plane or watch movies , shopping, and meeting sign-in, seriously infringing on the rights and interests of others
