Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The embodiment of the invention provides an information leakage tracking method for mobile terminal office chat software, which comprises the following steps of 101 to 104:
step 101, intercepting a screenshot action when it is monitored that a user captures a screenshot of an interface of office chat software of the mobile terminal, and acquiring a first image captured by the screenshot action.
When the screenshot action of the user is monitored, for example, a screenshot gesture is scribed or a screenshot shortcut key is pressed on a screen of the mobile terminal, the screenshot action is intercepted, so that the action of subsequently storing the intercepted image is interrupted, the operation step of adding the invisible watermark is carried out, when the adding of the invisible watermark is completed, the screenshot action is continuously stored after a second image is obtained, and the second image is used as the image of the screenshot of the user for storing.
In the embodiment of the invention, when the user captures the image, the watermark is added in the image capture, so that the slow running of the mobile phone software caused by embedding the watermark in all pages can be prevented.
Considering that a part of users need to add a screenshot without a watermark due to normal work needs, in order to meet the needs of the part of users, in the embodiment of the present invention, after the step 101 is performed to obtain the first image captured by the screenshot action, as shown in fig. 2, the following steps 201 to 203 may also be performed:
step 201, determining a user of office chat software according to a login account of the office chat software;
step 202, determining whether a user has the authority of not adding the watermark according to a preset white list;
and 203, if the user has the authority not to add the watermark, outputting the first image as the image intercepted by the user at this time.
The login account in the office chat software is bound with the personal information of the user, so that the user using the office chat software can be determined through the login account.
The white list records the employee list with the authority of not adding the watermark, and if the user has the authority of not adding the watermark, the first image can be directly output as the image intercepted at this time, so that the requirement that the user acquires a screenshot without the watermark in the white list is met.
Certainly, the employee list in the white list needs to be determined by the responsible person of the enterprise to which the user belongs, so as to reduce the risk that the divulgence tracing cannot be performed as much as possible.
Step 102, identifying the content of the first image, and determining a content area in the first image, wherein the content area comprises an area where the chat characters are located and an area where the chat pictures are located.
The chat texts and the chat pictures are generally main communication contents in the mobile terminal office chat software, and key information for avoiding disclosure is included in the main communication contents. In the invention, the content of the first image is identified, the content area in the first image is determined, the content area is the area where the chat characters and the chat pictures are located, invisible watermarks are added into the content area, and the invisible watermarks can be arranged on the information which is possibly leaked. Meanwhile, the invisible watermark can not be added in the non-content area due to the low risk of disclosure, so that the processing resource consumed in the process of adding the watermark is saved.
It should be noted that the chat characters and chat pictures referred in the embodiments of the present invention refer not only to the characters or pictures sent by the user during communication, but also to the characters, images, and image thumbnails in the file when the user opens the file or image thumbnail sent by the office chat software. For example, an attendance record Excel document is sent to a B by office chat software, the attendance record Excel document is opened in the office chat software for viewing by the B, and a screenshot action is made in the viewing process, so that an invisible watermark can be added in a screenshot content area.
Step 103, adding invisible watermarks in each content area of the first image to obtain a second image.
Compared with the traditional watermark, the invisible watermark cannot be perceived by a viewer and does not influence the picture effect. The watermark can not be perceived by a user and can not be removed by a common watermark removing method, but the watermark can be analyzed by a special watermark analyzing device to obtain the information recorded in the watermark.
And 104, outputting the second image as the image intercepted by the user at this time.
In the embodiment of the invention, if the user is not recorded in the white list, the user is determined not to have the authority of not adding the watermark, and at the moment, the employee identification of the user of the office chat software is determined according to the login account of the office chat software; and then adding invisible watermarks comprising employee identifications and screenshot operation time into each content area of the first image to obtain a second image.
The employee identification is used for uniquely identifying the user, the employee identification can be an employee name, an employee number or other identification information set for the employee, the identification information can be characters, numbers, letters and the like, and the specific expression form is set by the enterprise to which the user belongs.
The employee identification and the screenshot operation time are added in the content area, so that the source of the divulgence information can be conveniently determined, and the divulgence person directly responsible and the divulgence time can be found, thereby realizing rapid and effective tracing and greatly increasing the success rate of tracing.
As described above, after the step 104 is executed to output the second image as the image captured this time by the user, as shown in fig. 3, the following steps 301 and 302 may be executed:
step 301, extracting a divulged watermark from a content area of the divulged image;
step 302, extracting the employee identification and the screen-capturing operation time from the secret-divulging watermark, and determining a person responsible for secret divulging and the secret divulging time according to the employee identification and the screen-capturing operation time.
The second image obtained by processing the invisible watermark technology is invisible, and is not easy to be perceived by a divulging person, so that the probability of extracting the complete recognizable divulging watermark from the content area of the divulging image is greatly increased, and the tracing becomes simple and easy to operate.
In the embodiment of the invention, when the screenshot action of a user in the mobile terminal office chat software is monitored, the screenshot action is intercepted to obtain the first image, the content of the first image is identified to obtain the content area in the first image, the content area is the area where key information such as chat characters or chat pictures is located, invisible watermarks are added to the content area of the first image, so that the invisible watermarks can be ensured to be added to the key information, and compared with the prior art in which watermarks are added to a complete image, the invisible watermarks added to the key information cannot be removed or modified into other watermark contents which cannot be divulged and tracked in a cutting or tampering mode, so that the divulging and tracking can be effectively carried out; meanwhile, for the image which needs to be intercepted for work, the invisible watermark can not influence the normal reading of the chat characters or the chat pictures in the image. In addition, invisible watermarks are not added in the areas without the chatting characters or pictures, so that processing resources consumed when the invisible watermarks are added are saved.
The embodiment of the invention also provides an information divulgence tracking device of the mobile terminal office chat software, which is described in the following embodiment.
