Embodiment 1

[0031] This embodiment provides an information hiding method based on a two-dimensional code, and the execution subject may be an electronic device with computing and processing capabilities. Such as figure 1 As shown, the information hiding method includes the following steps.

[0032] Step 11. Obtain information to be hidden, where the information to be hidden includes hidden text information.

[0033] Hidden text information is information that the user wants to hide, for example, information used to prove that the QR code is a QR code issued by an authorized party.

[0034] Step 12. According to the information to be hidden, the preselected data module in the first two-dimensional code is modulated according to the preset data module color modulation rule to obtain a second two-dimensional code containing both hidden text information and plain text information; The dimensional code is a two-dimensional code generated according to the plaintext information, and the pre-data modu...

Embodiment 2

[0076] This embodiment provides an information hiding device based on a two-dimensional code. Such as figure 2 As shown, the information hiding device includes:

[0077] The information hiding device includes:

[0078] The obtaining unit 21 is configured to obtain information to be hidden, and the information to be hidden includes hidden text information;

[0079] The modulation unit 22 is configured to modulate the preselected data module in the first two-dimensional code according to the preset data module color modulation rule according to the information to be hidden, so as to obtain a second two-dimensional code containing both hidden text information and plain text information; The first two-dimensional code is a two-dimensional code generated according to the plaintext information, and the pre-data module is a module selected from the first two-dimensional code according to the amount of data of the implicit information; wherein,

[0080] The hidden text information in the se...

Embodiment 3

[0084] This embodiment provides an electronic device. The electronic device includes: a processor 31 and a memory 32; the memory 32 stores code; the processor 31 executes the code for executing the information described in Embodiment 1. Hide method.

[0085] The electronic device provided by the embodiment of the present invention provided in this embodiment has the following advantages: the two-dimensional code containing hidden text information also contains the plain text information, and the non-specific reader can recognize the plain text information, so the surface of the two-dimensional code The above is still a normal two-dimensional code, and is not suspected of being a special two-dimensional code, so that it will not attract the attention of the attacker, thus avoiding the possibility of being attacked from the source.

Abstract

The embodiment of the invention relates to the technical field of information security, in particular to an information hiding method and device based on a two-dimensional code and an electronic device. The information hiding method comprises the steps of obtaining to-be-hidden information, wherein the to-be-hidden information comprises hidden text information; modulating a pre-selected data module in the first two-dimensional code according to the to-be-hidden information and a preset data module color modulation rule to obtain a second two-dimensional code containing hidden text informationand plaintext information at the same time; wherein the first two-dimensional code is a two-dimensional code generated according to the plaintext information, and the pre-data module is a module selected from the first two-dimensional code according to the data size of the ciphertext information; wherein the ciphertext information in the second two-dimensional code can be identified by a preset identifier according to a preset data module color modulation rule. The embodiment of the invention has the advantages that the two-dimensional code cannot be suspected to be a special two-dimensional code, so that the attention of an attacker cannot be caused, and the attack possibility is avoided from the source.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of information security, and in particular to a method, device and electronic equipment for information hiding based on a two-dimensional code. Background technique [0002] At present, two-dimensional code technology has become the most important hot spot technology in the development of technologies and applications such as automatic identification technology and product identification, mobile marketing, and product traceability. Two-dimensional code technology, especially the matrix two-dimensional code represented by Hanxin code and QR code, is essentially a special structured graphic that distinguishes the two-dimensional code from other two-dimensional codes. The characteristic graphic frame of the macroscopic features and the data module sequence or combination which is distributed in the graphic frame and has a specific information arrangement and code definition. The data colle...
