Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. It is to be understood that the embodiments described in this specification are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention discloses a watermarking method based on an application program, exemplarily, as shown in fig. 1, the method comprises the following specific steps:
the method comprises the following steps: and logging in the application software client.
And the user logs in the application software client by using the login information. The login information may be a password, a user name, an authentication code, a job number, and the like.
And the application software client side receives the login information and then verifies the login information. Illustratively, the application client compares the received login information with its own stored password, username authentication code, job number, etc. And allowing the user to log in the application software client in the case of consistent comparison results. The present invention is not limited to the above verification manner, and for example, the application client may send the received login information to the cloud server, and the cloud server determines the validity of the user based on the verification algorithm according to the received login information.
Specifically, the application software client includes, but is not limited to, an Android client, an IOS client, a Windows client, a Mac client, and a Linux client.
Step two: watermark information is generated periodically.
Exemplarily, fig. 2 shows a schematic diagram of information interaction between an application software client and a background server according to an embodiment of the present invention. As shown in fig. 2, after the user completes login, the application client sends an application message to the background server. And after receiving the application information sent by the application software client, the background server generates a traceability identifier according to the application information. Wherein the application information includes a user ID. And the background server generates a tracing identifier according to the user ID. The USER ID is a unique identifier (USER Identification, abbreviated as USER ID) of the USER identity. Each user corresponds to one user ID, and the uniqueness of each user ID is guaranteed.
Table 1 tracing identifier table
| User ID | Tracing identifier |
| 101116 | A10B11C16 |
| 111214 | A11B12C14 |
| 122115 | A12B21C15 |
| 132217 | A13B22C17 |
| 142319 | A14B23C19 |
| 152411 | A15B24C11 |
| 211412 | A21B14C12 |
| 221513 | A22B15C13 |
Exemplarily, as shown in table 1, a tracing identifier table is stored in the background server in advance, the tracing identifier is a character string, and each user ID in the table corresponds to a specific tracing identifier. For example: the application software client sends application information, wherein the user ID in the application information is as follows: 101116, the background server matches the user ID with the tracing identifier table, and retrieves the tracing identifier: a10B11C 16. The application software client sends application information, wherein the user ID in the application information is as follows: 221513, the background server matches the user ID with the tracing identifier table, and calls the tracing identifier: a22B15C 13.
The method for generating and acquiring the tracing identifier is not limited to the method based on the tracing identifier table, and may also be implemented by other tracing identifier generation methods, for example, by using a two-dimensional code generation rule, the background server converts the received user ID into a two-dimensional code, where the two-dimensional code is the tracing identifier corresponding to the user ID.
The tracing identifier has a one-to-one correspondence relationship with the user ID, and the tracing identifier has uniqueness in the same system.
And the background server side sends the generated tracing identifier to the application software client side. And after receiving the tracing identifier issued by the background server, the application software client sends user information to the background server. And after receiving the user information, the background server binds the user information and the source tracing identifier.
Specifically, the user information includes N different types of information, and the traceability identifier can be divided into N parts. And the background server establishes a one-to-one corresponding binding relationship between the N pieces of information in the user information and the N pieces of the tracing identifier. Illustratively, the tracing identifier generated by the background server is: a10B11C 16. The user information received by the background server comprises: enterprise identification of device registration: company A; employee name: opening to small three; job number: 001. the background server binds the "A10" in the traceability identifier "A10B 11C 16" with the enterprise identifier "company A" registered by the equipment in the user information, binds the "B11" in the traceability identifier "A10B 11C 16" with the employee name "Zhang Xiao III" in the user information, and binds the "C16" in the traceability identifier "A10B 11C 16" with the job number "001" in the user information.
After the information is bound, the background server side can inquire the corresponding user information through the source tracing identifier. This way a divulgence tracing is performed. For example: after the information is bound, the background server can inquire an enterprise identifier 'company A' of the device registration through 'A10'; the background server can inquire the name of the employee, namely Zhang Xiao III, through the name of B11.
The step of binding the user information and the tracing identifier can also be realized by an application software client.
And after receiving the tracing identifier issued by the background server, the application software client generates watermark information according to the tracing identifier.
Illustratively, the watermark information is generated in three ways including, but not limited to, the following three ways:
the first method is as follows: a method for generating a matrix watermark of a dot matrix.
After receiving a tracing identifier issued by a background server, an application software client combines the tracing identifier, a terminal IMEI number, local time and other information to generate watermark information, and sets a plurality of dot matrix matrixes according to the watermark information. The bitmap at different positions contains different specific watermark information. As shown in fig. 3, the watermark information includes: tracing identification, terminal IMEI number and local time, and the application software client generates three bitmap matrixes according to the watermark information. The upper left bitmap contains enterprise information "A10", the middle right bitmap contains employee information "B11", and the lower left bitmap contains local time information "10: 16".
The second method comprises the following steps: and generating the special font type watermark.
After receiving the tracing identifier issued by the background server, the application software client combines the tracing identifier, the IMEI number of the terminal, the local time and other information to generate watermark information, and then sets the watermark information into a special font. For example, the watermark information includes the tracing identifier, the terminal IMEI number, and the local time, and the watermark information is set to be in a light gray inclined font. As shown in fig. 4, the watermark information is shown as "a 10B11C 16E 2010: 16" and in a light gray slanted font. Wherein "A10B 11C 16" represents the tracing identifier, "E20" represents the terminal IMEI number, and "10: 16" represents the local time.
The third method comprises the following steps: a vector diagram watermark generation method.
After receiving the tracing identifier issued by the background server, the application software client combines the tracing identifier, the IMEI number of the terminal, the local time and other information to generate watermark information. The application software client side respectively encodes various types of information in the watermark information into vector diagrams with fixed lengths M, divides the watermark into a plurality of equally divided information blocks, divides the inside of each information block into M pixel areas according to a preset rule, and sequentially fills the M pixel areas into the vector diagrams which are designed in advance. Illustratively, as shown in fig. 5, the watermark information includes a tracing identifier, a terminal IMEI number and a local time. The application software client encodes the watermark into three vector diagrams with the same length, and the three vector diagrams respectively represent the tracing identifier, the IMEI number of the terminal and the local time. The application software client divides the watermark into 3 information blocks, and respectively introduces vector diagrams corresponding to a tracing identifier 'A10B 11C 16', a terminal IMEI number 'E16' and local time '10: 16' into the 3 information blocks.
The watermark generated by the embodiment of the invention can be an invisible watermark.
The method for generating the watermark information can update the watermark information periodically according to a preset time period. Illustratively, every 1 minute, the application client regenerates the watermark information.
The watermark information generation step can also be realized by a background server, and the background server directly sends the generated watermark information to the software client.
Step three: a masking layer is obtained or created.
If the display interface of the current application program has the cover layer, the application software client acquires the cover layer; and if the display interface of the current application program does not have the covering layer, the application software client side creates the covering layer.
Specifically, the cover layer refers to a view displayed on the application display interface. For example, the cover layer includes, but is not limited to, a floating window and the view of the uppermost layer in the root view system.
Specifically, the root view is the top-most view system on the display interface relative to the child views. The root view hierarchy is created at the same time as the display interface is created, with the purpose of storing all the child views. By analogy to a "one" view tree, the root of the tree is its root (root view hierarchy).
Illustratively, based on the Android platform, when a floating window and a root view system exist in a display interface of a current application program at the same time, an application software client acquires the floating window as a cover layer.
Based on the Android platform, in a display interface of a current application program, a floating window is absent and a root view system is provided, and an application software client acquires the view of the uppermost layer in the root view system as a covering layer.
For another example, when the application is based on the Android platform, in the display interface of the current application, there is no floating window and there is a root view system, and the application client creates a floating window as a cover layer.
When the IOS platform is based, no floating window exists and a root view system exists in the display interface of the current application program. And the application software client acquires the view of the uppermost layer in the root view system as a covering layer.
As can be seen from the above, in the display interface of the current application program, the root view system necessarily exists; the floating window is a viewing layer independent of the root view system. When the suspension window and the root view system exist simultaneously, the suspension window is always above the view of the uppermost layer in the root view system, and the suspension window is selected as the covering layer.
And if the display interface of the current application program has no floating window and has a root view system, but the operating system of the application program is operated to generate the floating window, and then the floating window is created as a cover layer.
And the top view of the display interface of the current application program is taken as a cover layer, so that the watermark information is ensured to be always displayed on the top.
Step four: and acquiring or newly building a watermark window, and importing the watermark information into the watermark window.
The window body is a data display carrier and is used for displaying watermark information. The creation of the watermark window and the introduction of the watermark information into the watermark window can be realized by corresponding codes.
And if the display interface of the current application program has a blank window, the application software client acquires the blank window as a watermark window. And the application software client-side fully tiles the watermark information in the watermark window.
And if the display interface of the current application program has no blank window, the application software client side creates a watermark window. And the application software client imports the watermark information into the watermark window.
Step five: and adding the watermark window into the cover layer.
And if no window body exists in the cover layer, the application software client imports the watermark window body into the cover layer.
And if the window exists in the cover layer, the application software client deletes the window and imports the watermark window into the cover layer.
Exemplarily, based on an Android platform, a floating window is arranged in a display view of a current application program and serves as a covering layer, and an application software client determines whether a window exists in the floating window.
And if the window exists in the floating window, the application software client deletes the window and imports the watermark window into the floating window. And if the floating window has no window, the application software client directly imports the watermark window into the floating window.
Based on the IOS platform, a root view system exists in a display view of a current application program, an uppermost view in the root view system serves as a covering layer, and an application software client judges whether a window exists in the uppermost view in the root view system.
And if the window exists in the view at the uppermost layer in the root view system, the application software client deletes the window and introduces the watermark window into the view at the uppermost layer in the root view system. And if no window exists in the top view in the root view system, the application software client directly imports the watermark window into the top view in the root view system.
Therefore, no matter based on the Android platform or the IOS platform, the watermark window is imported into the covering layer of the current application program display interface, namely, the watermark information is always displayed on the top of the display interface of the application software client. Therefore, the watermarking processing method provided by the invention has strong compatibility, is suitable for application programs of different systems, has good protection effect and cannot be covered by other display contents of the display page.
When illegal persons take candid shots or screen shots on the screen or equipment or application program protected by the method, the watermark information generated according to the method is embedded into the corresponding image, if the image is leaked out, the basic information of the divulged equipment can be decoded according to the method and the uniqueness of the association of the watermark information, the tracing identifier and the user information, and then the divulged people can be traced back to the related divulged people.
Because the generation of the watermark information is periodic, the watermark information can be periodically regenerated according to a preset period. Therefore, each time the watermark information is regenerated, the process of embedding the watermark information in the cover layer is newly performed. Illustratively, every 1 minute, the application software client regenerates the watermark information, and according to the method, the generated watermark information is added to the newly-built watermark window, and then the watermark window is added to the cover layer from which the original window is removed.
In summary, the process of embedding watermark information in the cover layer is shown in FIG. 6,
generating watermark information periodically according to the watermark generation mode;
judging whether a covering layer exists or not; specifically, whether a cover layer exists in the display view of the current application program is judged.
If the covering layer is not available, the covering layer is created; if the covering layer exists, the covering layer is obtained;
judging whether a window is added in the covering layer;
if the window body is already arranged in the covering layer, removing the original window body in the covering layer, and newly building a watermark window body; if no window body exists in the covering layer, a watermark window body is newly built; specifically, since the watermark information is updated periodically, the cover layer needs to be emptied before newly generated watermark information is introduced into the cover layer. And removing the original window body in the covering layer to prevent the watermark in the original window body from covering and ghosting the newly generated watermark.
Adding the newly generated watermark information into the watermark window;
and adding the watermark window into the cover layer.
After the watermark information embedding processing is completed, the watermark information is always displayed in the top of the current interface. In the process of embedding the watermark information into the cover layer, a newly-built watermark window body can be added into the cover layer without the window body, and then the watermark information is imported into the watermark window body.
