The digital watermark is protection information embedded into the carrier file by using a computer algorithm, can be identified and recognized by others by embedding the digital watermark into the digital carrier, and does not influence the use value of the carrier file. Through the digital watermark, the purpose of confirming the content creator can be achieved. However, the digital watermark generated by the related art is easily tampered and imitated by others, so that the data is easily stolen and used by others, and the security of the data is not high.
In view of the above drawbacks of the related art, embodiments of the present invention provide a watermark adding method, which can prevent a watermark from being tampered, and improve data security. In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart of an implementation process of a watermarking method according to an embodiment of the present invention, where an execution subject of the method is a first device, and the first device includes: computers, tablets, servers, etc. As shown in fig. 1, the watermarking method includes:
s101, when detecting that a second device is connected to a communication interface of a first device, acquiring user information from the second device; the user information is user information of an application program installed in the first device; the second device is used for carrying out hardware encryption on the application program.
In the embodiment of the present invention, the second device may be connected to the communication interface of the first device, the second device stores therein user information of the application installed in the first device, and the user information may be identity information, such as a user name and a company name, registered when the user uses the application. In practical application, when a user performs identity registration, the second device is connected to the communication interface of the first device, the first device stores user information in the second device, and then the first device hides or deletes the local user information of the first device. Therefore, only by combining the first device and the second device, the first device can acquire the user information, so that the user information can be prevented from being forged by other people by using the first device.
In practical applications, the second device may be a hardware dongle, which is an intelligent hardware tool with application protection function provided for application developers, and includes hardware for connecting to a communication interface of a computer, such as a parallel port or a Universal Serial Bus (USB). The computer can check whether the hardware encryption lock is connected to the communication interface by exchanging data (namely reading and writing the hardware encryption lock) through the interface function and the hardware encryption lock; the computer may also encrypt the application's files using the tools attached to the hardware encryption lock. The computer can set multiple application program locks in the application program, and the hardware encryption locks are used as keys to open the application program locks. If the hardware encryption lock is not connected to the communication interface of the computer, the computer cannot open the application program lock set by the application program, and the application program cannot be executed normally. The hardware encryption lock is based on a hardware protection technology, and aims to protect an application program and data in the application program and prevent the data from being illegally used.
In practical application, the application program may be computer aided Design software (AutoCAD), an installation program of the AutoCAD is stored in the hardware encryption lock, when the AutoCAD needs to be installed in the computer, the hardware encryption lock is inserted into the USB interface of the computer, and the AutoCAD is automatically installed after the computer obtains the installation program of the AutoCAD from the hardware encryption lock. After the AutoCAD installation is completed, registration and activation are required for use. When the user registers, the computer sends the registered user information to the hardware encryption lock for storage, and then the user information of the computer is hidden or deleted. After the AutoCAD is installed, the activation is needed, and if the activation is not done, all functions of the AutoCAD cannot be used. The activation code of the AutoCAD is stored in the hardware encryption lock, when the AutoCAD needs to be activated, the hardware encryption lock is inserted into a USB interface of the computer, the hardware encryption lock sends the activation code to the computer, and the computer receives the activation code and then activates the AutoCAD.
When the watermark needs to be generated, whether a second device is connected to the communication interface of the first device needs to be detected, and when the second device is detected to be connected to the communication interface of the first device, user information is obtained from the second device.
Further, referring to fig. 2, in an embodiment, the obtaining user information from the second device when it is detected that the second device is connected to the communication interface of the first device includes:
s201, when detecting that the second device is connected to the communication interface of the first device, acquiring the verification code sent by the second device.
In the embodiment of the present invention, the second device and the application program on the first device have a binding relationship, one application program is correspondingly bound to one second device, and only when the second device having the binding relationship with the application program is connected, the first device can open and run the corresponding application program. Where the verification code sent by the second device is used to verify that the second device has a binding relationship with the application on the first device. The second device is equivalent to the key of the application program, and the first device can run the application program only by connecting the correct second device.
S202, verifying the verification code to obtain a verification result.
And the application program verifies the verification code and judges whether the second equipment has a binding relationship with the application program. For example, the second device and the application both have a same serial number, when the second device is inserted into the second device, the second device sends the serial number to the first device, the first device compares the serial number with the serial number in the application, and if the serial numbers of the two parties are the same, the authentication is successful.
The verification result comprises verification success and verification failure of the verification code, the verification success represents that the second device has a binding relationship with the application program, and the verification failure represents that the second device does not have a binding relationship with the application program.
S203, acquiring user information from the second device under the condition that the verification result represents that the verification of the verification code is successful.
And if the verification of the verification code is successful, the second equipment and the application program have a binding relationship, and the first equipment acquires the user information from the second equipment.
Here, the obtaining of the user information from the second device may be that the first device sends a user information obtaining request to the second device, and the second device returns the corresponding user information to the first device according to the request. The first device may send the verification result to the second device, the second device analyzes the verification result, and the second device sends the user information to the first device when the verification result represents that the verification code is successfully verified.
The second device is usually verified, and the user information can be obtained only through the second device which has a binding relationship with the application program, so that the user information is prevented from being obtained through the forged second device by other people, and the authenticity and the counterfeiting difficulty of the watermark information are enhanced.
S102, generating a watermark image at least comprising the user information and the equipment information of the first equipment.
In this embodiment of the present invention, the device information of the first device is device identification information of the first device, and the device identification information can uniquely identify the first device, such as a media access control address (MAC).
In practical application, a plurality of application programs generally need to be registered to be normally used, when the application programs are registered, the application programs bind the unique device identification of the computer with the application programs, when watermark images need to be generated, the first terminal obtains the unique device identification bound by the application programs, and the watermark images are generated based on user information and the unique device identification.
Further, referring to fig. 3, in an embodiment, the generating a watermark image including at least the user information and the device information of the first device includes:
s301, determining the information content category needing to be encrypted and displayed in the watermark image; the information content category includes at least one of the user information and the device information.
Here, the information content category includes at least one of the user information and the device information. That is, if the user does not want others to see some of the user information and the device information, the information is encrypted. For example, if the user does not want to expose the user information, the user information is displayed encrypted in the watermark image.
S302, coding the information corresponding to the information content category through a set algorithm to obtain encrypted information.
In the embodiment of the present invention, the setting algorithm is an encryption algorithm, and is configured to encode the information corresponding to the information content category, and encode the information corresponding to the information content category into encrypted information. The information corresponding to the information content category is encoded in order to prevent others from imitating the same watermark in order to avoid exposing the information.
S303, generating a watermark image at least including the user information and the device information of the first device; and displaying the information corresponding to the information content category as the encrypted information in the generated watermark image.
On the generated watermark image, the information corresponding to the information content category is displayed as encrypted information, so that the information corresponding to the original information content category is hidden, and all the information cannot be exposed by the watermark image. A part of information is encrypted and displayed, so that the privacy of a user can be protected; a part of the information is disclosed and displayed, which can indicate the identity of the content creator and protect the copyright of the content creator.
In practical application, the internal clock of the hardware dongle can provide time information, and the watermark image can be generated from the time information, the user information and the device information of the first device. According to the watermark image, the user, the use place and the use time can be traced, and the intellectual property rights are protected.
S103, adding at least one watermark image on an interface view of the application program; the at least one watermark image overlays an interface view of the application.
Further, referring to fig. 4, in an embodiment, the adding at least one watermark image on the interface view of the application program includes:
s401, determining configuration information of the watermark image; the configuration information represents the display effect of the watermark image on the interface view.
The configuration information represents the display effect of the watermark image on the interface view of the application program, and comprises any one of the following items: a transparency of each of the at least one of the watermark images; a size of each of the at least one of the watermark images.
In practical applications, the configuration information of the watermark image includes a color, a font, a density, a transparency, a rotation angle, a size of a dimension, and the like of the watermark image. Determining the configuration information of the watermark image can ensure that the watermark image can be identified and recognized by others and the use value of the carrier file is not influenced.
S402, adding at least one watermark image on the interface view of the application program based on the configuration information.
For example, assuming that the configuration information is that the rotation angle of the watermark image is 45 degrees, the shape of the watermark image is rectangular, the size of the watermark image is 3 × 2, and the interval of each watermark image is 2 cm, then, the length or width of the watermark image is 45 degrees with respect to the horizontal direction of the window, and at least one watermark image is diffusion-filled into the whole interface view according to the size of 3 × 2, so that the interval between every two adjacent watermark images on the interface view is 2 cm.
Related art typically only adds a watermark image to a portion of an interface view, for example, in a word processing software, typically only adds a watermark image to a document page portion of a word processing application, and does not add a watermark image to the rest of the application interface, for example, a menu bar. In the embodiment of the present invention, the watermark image is added to the whole window view, as shown in fig. 5, the interface view of the application program includes the document part, and the embodiment of the present invention fills the watermark image in the whole interface view of the application program, so that the watermark image exists in the document part of the interface view or in other parts except the document part. Compared with the method that the watermark image is only displayed on the document part, the method and the device for displaying the watermark image display on the whole interface view can indicate the copyright of the document to the outside and warn others not to illegally use the document.
When detecting that a second device is connected to a communication interface of a first device, acquiring user information of an application program installed in the first device from the second device, generating a watermark image at least comprising the user information and the device information of the first device, and adding at least one watermark image on an interface view of the application program to enable the at least one watermark image to cover the interface view of the application program. The embodiment of the invention acquires the user information through the second equipment, can prevent other people from using the first equipment to forge the user information, and enhances the authenticity and the counterfeiting difficulty of the information on the watermark image. In addition, the watermark is added on the whole interface view, so that the copyright of the author can be indicated, and the illegal use of the labor achievement of the author by other people is prevented.
Referring to fig. 6, in one embodiment, the watermarking method further includes:
s601, acquiring the size change information of the interface view.
If the first device changes the size of the interface view of the application program, namely the user enlarges and reduces the interface view of the application program, the size change information of the interface view is obtained, and the size change information comprises the zoom times of the length and the zoom times of the width of the interface view.
S602, according to the size change information, any one of the following items is adjusted: a number of watermark images of the at least one watermark image; a size of each of the at least one watermark image.
And if the size of the interface view of the application program is changed, the size of the watermark image and the number of the watermark images on the interface view need to be correspondingly adjusted. For example, if the window is reduced, it may result in the text on the watermark image being obscured if the reduced watermark image is followed. At this time, the watermark images can be properly reduced, the number of the watermark images is reduced, the excessive number of the watermark images is prevented, the attractiveness of the watermark images is not influenced, and the normal identification of the watermark images is not influenced.
Further, when the application program outputs a visual file, at least one watermark image is added to each page of the visual file.
In practical application, when an application program prints or prints and previews, a watermark drawing function is called to realize synchronous output of watermark images, at least one watermark image is added to each page of a visual file, and a user is prevented from stealing file contents through a printing and print previewing interface.
Referring to fig. 7, a schematic diagram of a watermarking flow provided by an application embodiment of the present invention is shown.
And after the hardware encryption lock is inserted into the computer, the user information and the time information are acquired from the hardware encryption lock, and the application program acquires the equipment information of the computer. And the computer generates a watermark image according to the user information, the time information and the equipment information, and embeds the watermark image into the whole window view of the application program.
Referring to fig. 8, it shows a schematic flowchart of a watermarking method provided by an application embodiment of the present invention, where the watermarking flow includes:
s801, providing date and user information by the internal clock of the hardware encryption lock.
S802, the application program provides host computer information.
