[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] In one embodiment, Figure 2As shown, a watermark method is provided, and the method is applied to a terminal as an example for explanation. The terminal may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, and portable wearable devices, including the following steps:

[0044] Step S110, obtaining encryption parameters set by the user according to the personal electronic profile picture.

[0045] Among them, personal electronic data images include images of electronic data such as scanned copies of the user's ID card and bank card. The user enters encryption parameters through a terminal such as a computer or a mobile phone. The encryption parameters include Chinese characters, English letters, Greek letters or numbers. The encryption parameters are equivalent to the password set by the user to distinguish them from the encryption parameters set by others. The particularity of the set encryption parameters makes the generated watermark different from the watermarks set by others. For example, the encryption parameter is a six-digit password, specifically "000000".

[0046] Step S120, encoding the encryption parameter to obtain the encoding parameter.

[0047] The encoding may be ASCII code, and the encryption parameter is encoded as binary data, that is, the encoding parameter is binary data. Of course, the encoding may also be encoded in other ways, such as Unicode, GBK, GB2312, UTF-8, etc. For example, the encryption parameter is "000000", and the encoding parameter obtained after encoding is "110100111010".

[0048] Step S130, performing a splitting operation on the coding parameters to obtain discrete point information; the discrete point information includes the position of the discrete point in the personal electronic profile picture and the RGB value of the discrete point.

[0049] Among them, the splitting operation is to convert the coding parameter into discrete points. For example, the coding parameter is "110100111010", and the splitting operation can be segmented according to the coding parameter (binary data) in a fixed format, then the coding parameter "110100111010" is split into 110100, 111010, 110100 is converted into decimal 52, 111010 is converted into decimal 58, 52 is used to represent the position of the discrete point in the image, and 58 is used to represent the RGB value of the discrete point. Of course, 52 cannot directly represent the position of the discrete point in the image, and a mapping table can be formulated to achieve it. Similarly, 58 cannot directly represent the RGB value of the discrete point, and it can be achieved through another mapping table. Of course, the splitting operation can also be in other forms, which can be set as needed, and will not be repeated here.

[0050] Step S140: generating a ciphertext watermark image on the personal electronic profile picture page according to the position of the discrete point in the discrete point information and the RGB value of the discrete point.

[0051] Wherein, the ciphertext watermark image generated by the discrete point information on the personal electronic profile picture page is dot matrix information, and the dot matrix information includes a scannable QR code image or a barcode image. The ciphertext watermark image can overlap with the content of the personal electronic profile picture, or it can be in the blank space of the personal electronic profile picture. When the ciphertext watermark image overlaps with the content of the personal electronic profile picture, the ciphertext watermark image is distinguished from the content of the personal electronic profile picture by the RGB value. Wherein, the saturation, brightness and contrast of the ciphertext watermark image can be set by setting the RGB value, that is, the saturation, brightness and contrast of the ciphertext watermark image are distinguished from the content of the personal electronic profile picture by the saturation, brightness and contrast of the ciphertext watermark image.

[0052] In the above-mentioned watermark data processing method, the encryption parameter input by the user can be a password set by himself, and a ciphertext watermark image is generated according to the encryption parameter to distinguish it from the watermark set by other people. Compared with the stereotyped watermark method of setting text watermarks such as "limited to patent application purposes" in the prior art, the watermark setting method of the present application is not easily copied by others, can be realized for different people, and improves the security of watermark encryption of personal electronic data images.

[0053] In one of the embodiments, the step of encoding the encryption parameter to obtain the encoding parameter includes: encoding the encryption parameter using an encryption key to obtain the encoding parameter.

[0054] The encryption key is used to encrypt the encryption parameters, and the specific encoding method can be encoded using an existing encryption algorithm. The encryption key can be determined by the data user, and the subsequent data user decrypts the encryption parameters using the encryption key to determine that the current data is provided by the correct data provider.

[0055] In one embodiment, if Figure 2 As shown, the step of performing a splitting operation on the coding parameter to obtain discrete point information includes: S131, determining whether the length of the coding parameter is greater than a preset value; S132, if the length of the coding parameter is greater than the preset value, performing a splitting operation on the coding parameter to obtain discrete point information.

[0056] The length of the encryption parameter is proportional to the length of the encoding parameter. The longer the length of the encryption parameter is, the less likely it is to be copied by someone, and the more secure it is. The preset value can be set as needed. Generally, if the length of the encoding parameter is greater than the preset value, it means that the encryption parameter corresponding to the encoding parameter is secure.

[0057] In one of the embodiments, the step of performing a splitting operation on the coding parameter to obtain discrete point information includes: when the length of the coding parameter is greater than a preset value, intercepting data of the preset value length of the coding parameter; and performing a splitting operation on the data of the preset value length to obtain discrete point information.

[0058] Among them, the encoding parameter is truncated with data of a preset value length, that is, the encryption parameter is selected with data of a preset value length, and the encoding parameter with the preset value length is easy to encode. After the encoding parameter has the data of the preset value length, the user who inputs the encryption parameter can be notified to select data of the preset value length from the encryption parameter, so that subsequent users can verify the encrypted watermark content of the personal electronic data picture.

[0059] In one of the embodiments, the watermark data processing method further includes: scanning the ciphertext watermark image to obtain encryption parameters; the encryption parameters are used to verify the authenticity of the personal electronic profile image.

[0060] The ciphertext watermark image is scanned by a scanning terminal, and the scanning terminal may be a terminal used by the data user, such as a mobile phone used by the data user. For example, the ciphertext watermark image is a QR code, and the data user obtains encryption parameters by scanning the QR code image, and determines whether the data provided by the data provider is correct through the encryption parameters.

[0061] In one of the embodiments, the step of scanning the ciphertext watermark image to obtain encryption parameters includes: scanning the ciphertext watermark image to obtain discrete point information; the discrete point information includes the position of the discrete point in the personal electronic profile picture and the RGB value of the discrete point; according to the position of the discrete point in the personal electronic profile picture and the RGB value of the discrete point in the discrete point information, the encoding parameters are calculated; and the encryption parameters are calculated according to the encoding parameters.

[0062] Among them, the process of scanning the ciphertext watermark image to obtain the encryption parameters is the opposite of the process of generating the ciphertext watermark image according to the encryption parameters. The ciphertext watermark image is scanned by a scanning terminal, and the ciphertext watermark image is subjected to image processing to obtain discrete point information; according to the position of the discrete points in the personal electronic data image and the RGB value of the discrete points in the discrete point information, the encoding parameters are calculated by a merging operation, and the calculation process of the merging operation is opposite to that of the splitting operation; and then the encryption parameters are obtained by inverse encoding according to the encoding parameters. This embodiment obtains the encryption parameters by scanning with a scanning terminal, which is convenient for users to use.

[0063] In one of the embodiments, the step of scanning the ciphertext watermark image to obtain encryption parameters includes: scanning the ciphertext watermark image to obtain encryption parameters according to an input encryption key.

[0064] The ciphertext watermark image is scanned by a scanning terminal, and the scanning terminal is a terminal used by the data user. After obtaining the encryption parameters, the data user can use the encryption parameters to authenticate its own identity. For example, if the data user is an insurance collector, when collecting fees from the data provider, it can use the encryption parameters to indicate its own identity. Similarly, when the data provider receives the insurance fee notification, it can determine whether it is the correct insurance collector based on the encryption parameters provided by the other party. For example, after scanning the ciphertext watermark image, the scanning terminal displays a prompt message for inputting the encryption key. According to the prompt message, the user inputs the encryption key, and the scanning terminal decrypts the encryption parameters based on the encryption key.

[0065] The scanning terminal is a terminal used by the data provider, such as a mobile phone. In the case of a personal electronic data image being leaked, the data provider can obtain the encryption parameter by scanning the ciphertext watermark image of the leaked data, and can know who leaked the personal electronic data image. Because the encryption parameter is unique, the data provider sets a unique encryption parameter when providing the personal electronic data image with the encrypted watermark image. According to the encryption parameter, it can be known what the personal electronic data image is used for, and the data user for this purpose is also unique.

[0066] It should be understood that although Figure 2-3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-3 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.

[0067] In a specific embodiment, the user inputs encryption parameters in the terminal, and the terminal processes the encryption parameters into discrete point information. According to the position of the discrete point in the personal electronic profile picture and the RGB value of the discrete point in the discrete point information, the discrete point is displayed at the corresponding position of the personal electronic profile picture. When the RGB value is red, a red point is displayed in the personal electronic profile picture, and when the RGB value is gray, a gray point is displayed in the personal electronic profile picture, and different encryption parameters correspond to different discrete point positions.

[0068] In one embodiment, Figure 3As shown, a watermark data processing device is provided, comprising: an encryption parameter acquisition module 210, an encoding module 220, a splitting operation module 230 and a watermark image generation module 240, wherein:

[0069] The encryption parameter acquisition module 210 is used to obtain the encryption parameters set by the user according to the personal electronic profile picture.

[0070] The user inputs encryption parameters through a terminal such as a computer or a mobile phone, and the encryption parameters include Chinese characters, English letters, Greek letters or numbers. The encryption parameters are equivalent to the password set by the user to distinguish them from the encryption parameters set by others. The particularity of the set encryption parameters makes the generated watermark different from the watermarks set by others.

[0071] The encoding module 220 is used to encode the encryption parameters to obtain encoding parameters.

[0072] The encoding may be ASCII code, and the encryption parameter is encoded as binary data, that is, the encoding parameter is binary data. Of course, the encoding may also be encoded in other ways, such as Unicode, GBK, GB2312, UTF-8, etc.

[0073] The splitting operation module 230 is used to perform a splitting operation on the encoding parameters to obtain discrete point information; the discrete point information includes the position of the discrete point in the personal electronic data picture and the RGB value of the discrete point.

[0074] The splitting operation is to convert the encoding parameters into discrete points.

[0075] The watermark image generation module 240 is used to generate a ciphertext watermark image on the personal electronic profile picture page according to the position of the discrete point in the personal electronic profile picture and the RGB value of the discrete point in the discrete point information.

[0076] Wherein, the discrete point information generates a ciphertext watermark image on the personal electronic profile picture page as dot matrix information or a QR code image. The ciphertext watermark image can overlap with the content of the personal electronic profile picture, or can be in a blank space of the personal electronic profile picture. When the ciphertext watermark image overlaps with the content of the personal electronic profile picture, the ciphertext watermark image is distinguished from the content in the personal electronic profile picture by the RGB value of the image. Wherein, by setting the RGB value, the saturation, brightness and contrast of the ciphertext watermark image can be set, that is, the saturation, brightness and contrast of the ciphertext watermark image are distinguished from the content of the personal electronic profile picture.

[0077] In one embodiment, the encoding module 220 is further used to obtain the encoding parameters after encoding the encryption parameters through the encryption key. The encryption key is used to encrypt the encryption parameters, and the specific encoding method can be encoded using an existing encryption algorithm. The encryption key can be determined by the data user, and the subsequent data user decrypts the encryption parameters through the encryption key to determine that the current data is provided by the correct data provider.

The length of the encryption parameter is proportional to the length of the coding parameter. The longer the length of the encryption parameter is, the less likely it is to be copied by someone, and the more secure it is. The preset value can be set as needed. Generally, if the length of the coding parameter is greater than the preset value, it means that the encryption parameter corresponding to the coding parameter is secure.

[0079] In one embodiment, the splitting operation module 230 includes: a truncation unit, used to truncate data of a preset value length of the encoding parameter when the length of the encoding parameter is greater than a preset value; and a splitting operation unit, used to perform a splitting operation on the data of the preset value length to obtain discrete point information.

[0080] Among them, the encoding parameter is truncated with data of a preset value length, that is, the encryption parameter is selected with data of a preset value length, and the encoding parameter with the preset value length is easy to encode. After the encoding parameter has the data of the preset value length, the user who inputs the encryption parameter can be notified to select data of the preset value length from the encryption parameter, so that subsequent users can verify the encrypted watermark content of the personal electronic data picture.

[0081] In one embodiment, the watermark data processing device further includes: a scanning module for scanning the ciphertext watermark image to obtain encryption parameters; the encryption parameters are used to verify the authenticity of the personal electronic data image. The scanning module can be a terminal used by the data user, such as a mobile phone used by the data user.

[0083] Among them, the process of scanning the ciphertext watermark image to obtain the encryption parameters is the opposite of the process of generating the ciphertext watermark image according to the encryption parameters. The ciphertext watermark image is scanned by a scanning terminal, and the ciphertext watermark image is processed to obtain discrete point information; according to the position of the discrete points in the personal electronic data image and the RGB value of the discrete points in the discrete point information, the encoding parameters are calculated by merging operation, and the calculation process of the merging operation is opposite to that of the splitting operation; and then the encryption parameters are obtained by reverse encoding according to the encoding parameters.
