A screen information leakage tracing system and method

Abstract

The invention discloses a screen information leakage tracing system and a screen information leakage tracing method. A system architecture that client screen information carries out watermark embedding and a server cooperates with an original business system to carry out centralized management and control is provided. The system comprises a screen watermark generation module, a Screen watermark display module, a server management and control module, a watermark information extraction module and a watermark information query module, can encode the equipment number, the user information and thetime information, can generate a screen watermark image, update the screen watermark image in real time, link the screen watermark image with a service system, and control the screen watermark image to be displayed on a client screen when a client views or modifies sensitive information. When screen information leakage occurs, the screen watermark information in the screen information leakage is extracted according to the obtained screen shot and screen shot images, secret divulging personnel and secret divulging time can be reliably traced, and sensitive information safety of enterprises or departments is protected.

Description

technical field [0001] The invention belongs to the technical field of network security, information protection, and screen information leak tracking and traceability. It specifically involves the use of embedded digital watermark protection in order to prevent user screen information from being leaked by screenshots or screen shots in a network environment, and the traceability system and traceability method adopted for leaked information. Background technique [0002] With the development of smart handheld terminals and mobile Internet technologies, it is inevitable that there will be prominent problems such as screenshots of sensitive information and leakage of photos in paperless office. Only by adopting security protection measures such as access control, information encryption, and log auditing, it is difficult to trace the source of information leaked in this way, and it cannot prevent the outflow of sensitive information. Because the image information in the digital...

Only by adopting security protection measures such as access control, information encryption, and log auditing, it is difficult to trace the source of information leaked in this way, and it cannot prevent the outflow of sensitive information

Because the image information in the digital environment is transferred to other carriers through the computer by taking pictures, although the information content has not changed, the way the information is carried has changed greatly. The general traceability technology is due to its tracking information The life cycle of the image is short and the anti-attack ability of the image is weak, and it is impossible to continue to track and trace the source in the case of digital-to-analog conversion and analog-to-digital conversion, perspective changes, and noise attacks on the information carrier.
