Screen display data protection method

Abstract

The invention discloses a screen display data protection method and belongs to the field of computer information safety. The method includes that the triggering mechanism and the watermark information of secret-associated data and a screen data protection system are set; a user accesses the secret-associated data and trigger the screen data protection system; the screen data protection system extracts current user information, generates watermark and displays the information; a secret divulging user is searched according to the watermark information on the secret divulging document. The protection system is triggered when the user accesses the secret-associated data and generates the protection watermark with the information of the current user to display the watermark on the screen, the possibility of stealing the secret-associated data and documents through camera shooting, screenshot, picture recording and the like is effectively reduced. Once the data are disclosed, the secret divulging source can be tracked quickly according to the user information recorded by the watermark in the secret divulging document. The watermark is set to be a two-dimensional code or a bar code, the user information can be hidden, the fact that the user who steals the information avoid or remove the watermark on purpose is avoided, and the safety coefficient of the secret-associated data is further improved.

Description

technical field [0001] The invention relates to a method for protecting electronic data, in particular to a method for protecting data displayed on a screen, and belongs to the field of computer information security. Background technique [0002] With the continuous development of computer technology and network technology, more and more data materials are used, stored and transmitted in the form of electronic files. However, while electronic files provide quick and convenient services, they also face the threat of being illegally used or embezzled. Therefore, people pay more and more attention to the security and protection of data, especially in the popularization of portable camera equipment today, it is easy to steal confidential data by taking pictures on the screen; Willfully steal and disseminate confidential data. [0003] In view of the above situation, the method of printing protection information is widely used at home and abroad to protect confidential data, th...

Problems solved by technology

This method can protect the confidential data to a certain extent, reducing the risk of the confidential data being stolen; For all the secret-related content, the stealer can deliberately avoid the watermark and steal other parts of the secret-related data; secondly, when accessing the privacy-related data in the browser and database, due to the particularity of these data formats, in the data There are many inconveniences in embedding watermarks, and private data is more likely to be leaked through screen photos, videos, or screenshots; finally, after a leak occurs, it is impossible to quickly locate and find the source of the leak for timely and necessary processing and protection improvements
