Embodiment 1

[0027] This embodiment provides an information hiding method based on a two-dimensional code, and its execution body may be an electronic device with computing and processing capabilities. Such as figure 1 As shown, the information hiding method includes the following steps.

[0028] Step 11. Obtain the information to be hidden, and the information to be hidden includes hidden text information.

[0029] Stealth information is information that the user wants to hide, such as information used to prove that the QR code is a QR code issued by an authorized party.

[0030] Step 12. Modulate the preselected data module in the first two-dimensional code according to the preset data module size modulation rule according to the information to be hidden, so as to obtain the second two-dimensional code containing both hidden information and plaintext information; the first two The two-dimensional code is a two-dimensional code generated according to the plaintext information, and the p...

Embodiment 2

[0056] This embodiment provides an information hiding device based on a two-dimensional code. Such as figure 2 As shown, the information hiding device includes:

[0057] The information hiding device includes:

[0058] An acquisition unit 21, configured to acquire information to be hidden, where the information to be hidden includes hidden text information;

[0059] The modulation unit 22 is used to modulate the preselected data module in the first two-dimensional code according to the preset data module size modulation rule according to the information to be concealed, so as to obtain the 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 data amount of the hidden text information; wherein,

[0060] The hidden text information...

Embodiment 3

[0064] This embodiment provides an electronic device, and the electronic device includes: a processor 31 and a memory 32; the memory 32 stores codes; the processor 31 executes the codes to execute the information described in Embodiment 1 Hide method.

[0065]The electronic device provided by this embodiment of the present invention has the following advantages: the two-dimensional code containing hidden text information also contains plain text information, and non-specific readers can recognize the plain text information, so the two-dimensional code surface It is still a normal QR code on the screen, and it is not suspected of being a special QR 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 electronic equipment. 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 size modulation rule to obtain a second two-dimensional code containing hidden text information and 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 size 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 field of information security technology, and in particular to a two-dimensional code-based information hiding method, device, and electronic equipment. Background technique [0002] At present, two-dimensional code technology has become the most important hot technology in the development of technologies and applications such as automatic identification technology and commodity 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, which distinguishes the two-dimensional code from other two-dimensional codes and has It consists of a characteristic graphic frame of macroscopic features and a sequence or combination of data modules distributed within the graphic frame with specific information arrangement and coding definitions. The dat...
