Problems solved by technology

[0005] However, the above-mentioned literature only considers the issue of employee information leakage from the perspective of the enterprise. As a result, although employees publish screenshots including enterprise certification watermarks, these images do not involve leaked content at all, but the enterprise is at the risk of self-interest. Considering that these screenshots will be used to find the corresponding employee, so as to privately retaliate against the employee, which has caused the company to use its advantages in technology and resources to damage the interests of the employee

Embodiment 1

[0069] like figure 2 As shown, the present invention provides a blockchain-based intelligent terminal cooperative screen capture method, the method comprising the following steps:

[0070] S1. Obtain the screenshot operation of the user on the first terminal to identify the first application on the current interface. If the first application is a preset authenticated confidential application, perform step S2; otherwise, directly acquire the The screenshot of the current interface; it should be noted that in the existing technology, enterprises often have internal social software platforms, such as corporate WeChat and other clients, for employees to communicate at work; The internal social software interface automatically adds plaintext watermark or ciphertext watermark and other types of digital watermarks when taking screenshots. Among them, the watermarks that cannot be viewed intuitively by the user are blind watermarks. For the method of adding blind watermarks, see fig...

Embodiment 2

[0098] like image 3 As shown, the present invention provides a blockchain-based intelligent terminal cooperative screen capture system, the system includes the following modules:

[0099] The first judging module is used to acquire the screenshot operation of the user on the first terminal, identify the first application program on the current interface, and execute the second judging module if the first application program is a preset authenticated secret-related application program ; Otherwise, directly obtain the screenshot of the current interface; it should be noted that in the prior art, enterprises often have internal social software platforms, such as enterprise WeChat and other clients, for employees to communicate at work; and in order to protect the enterprise Benefits, usually when the user takes a screenshot of the internal social software interface, a clear text watermark or a cipher text watermark and other types of digital watermarks are automatically added. A...

Embodiment 3

[0127] As another embodiment, the present invention provides an electronic device, including a memory, a processor, and a computer program stored on the memory and operable on the processor, wherein, when the processor executes the program, the The above-mentioned block chain-based intelligent terminal cooperative screen capture method.

Abstract

The invention provides an intelligent terminal collaborative screen capture method and system based on blockchain, an electronic device and a computer readable storage medium, and the method comprisesthe steps: searching printing equipment connected with a first terminal, and distinguishing the types of PDF files which can be printed by the printing equipment; if the permission of printing the interface content as the text PDF exists, printing the interface content as the text PDF, wherein at the moment, the text PDF obtained through printing does not contain blind watermark information, thenthe printing equipment converts the text PDF into the first screenshot picture, and the first screenshot picture is obtained through the second screenshot picture. Therefore, the extraction of all displayable contents of the current interface and the storage of the picture form are realized, so that the effect of obtaining the screenshot without executing the screenshot operation is achieved. Otherwise, the picture PDF is scanned, the information of the blind watermark in the picture in the picture PDF after scanning can be ignored, and the obtained first screenshot picture can effectively delete the information of the blind watermark.

Description

technical field [0001] The present application relates to the technical field of the present invention involving blockchain and smart terminal collaborative screen capture, and in particular to a blockchain-based smart terminal collaborative screen capture method and system. Background technique [0002] Digital watermarking technology is to embed some identification information, that is, digital watermark, directly into the digital carrier, or indirectly express it, without affecting the use value of the original carrier, and at the same time, it is not easy to be detected and modified again. But it can be identified and identified by the producer. Through the information hidden in the carrier, the purpose of confirming the disseminator of information, transmitting secret information or judging whether the carrier has been tampered with can be achieved. The so-called blind watermark refers to a watermark that cannot be perceived by humans, including invisible or inaudibl...
