Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 2, a watermarking method is provided, which is described by taking the method as an example applied to a terminal, which can be but is not limited to various personal computers, notebook computers, smart phones, tablet computers and portable wearable devices, and includes the following steps:
step S110, obtaining the encryption parameter set by the user according to the personal electronic data picture.
The personal electronic data picture comprises pictures of electronic data such as an identity card scanning piece, a bank card scanning piece and the like of a user. The user inputs encryption parameters through a computer, a mobile phone and other terminals, wherein the encryption parameters comprise Chinese characters, English letters, Greek letters or numbers. The encryption parameter is equivalent to a password set by a user and is different from the encryption parameter set by others, and the generated watermark is different from the watermark set by others through the particularity of the set encryption parameter. For example, the encryption parameter is a six-digit password, specifically "000000".
And step S120, encoding the encryption parameters to obtain encoding parameters.
The encoding can adopt ASC LL code, the encoding parameter is binary data after being encoded, that is, the encoding parameter is binary data, of course, the encoding can also adopt other encoding modes, such as Unicode, GBK, GB2312, UTF-8 and the like, for example, the encoding parameter is "000000", and the encoding parameter is "110100111010" after being encoded.
Step S130, carrying out splitting operation on the coding parameters to obtain discrete point information; the discrete point information includes a position of the discrete point in the picture of the personal electronic material and RGB values of the discrete point.
Wherein the splitting operation is to convert the encoding parameters into discrete points. For example, if the encoding parameter is "110100111010", the splitting operation may be performed according to a fixed format based on the encoding parameter (binary data), and the encoding parameter "110100111010" is split into 110100, 111010, 110100, 52 and 58, where 52 and 58 are decimal numbers, 52 is used to represent the position of a discrete point in an image, and 58 is used to represent the RGB value of the discrete point, and of course, 52 cannot directly represent the position of the discrete point in the image, and a mapping table may be prepared to implement this, and similarly 58 cannot directly represent the RGB value of the discrete point, and this may be implemented by another mapping table. Of course, the splitting operation may also be in other forms, and may be set as needed, which is not described herein again.
Step S140, generating a ciphertext watermark image on the page of the personal electronic material picture according to the position of the discrete point in the personal electronic material picture in the discrete point information and the RGB value of the discrete point.
And the ciphertext watermark image generated by the discrete point information on the personal electronic data picture page is dot matrix information, and the dot matrix information comprises a two-dimensional code image or a bar code image which can be scanned. The ciphertext watermark image can be superposed with the content of the personal electronic material picture or can be positioned in the blank of the personal electronic material picture. When the ciphertext watermark image is coincident with the content of the personal electronic data picture, the ciphertext watermark image is distinguished from the content of the personal electronic data picture through the RGB value. The saturation, brightness and contrast of the ciphertext watermark image can be set by setting the RGB value, namely, the saturation, brightness and contrast of the ciphertext watermark image are distinguished from the content of the personal electronic data picture.
In the watermark data processing method, the encryption parameter input by the user can be a password set by the user, the ciphertext watermark image is generated according to the encryption parameter so as to be distinguished from watermarks set by other people, and compared with a uniform watermark mode in the prior art, such as 'patent application limited only', the watermark setting mode is not easy to be copied by other people, thousands of people can be realized, and the watermark encryption safety of the personal electronic data image is improved.
In one embodiment, the step of obtaining the encoding parameters after encoding the encryption parameters includes: and obtaining the coding parameters after coding the encryption parameters through the encryption key.
The encryption key is used for encrypting and encoding the encryption parameter, and the specific encoding mode can adopt the existing encryption algorithm for encoding. The encryption key may be determined by the material user, and the subsequent material user decrypts the encryption parameter with the encryption key to determine that the current material is provided by the correct material provider.
In one embodiment, as shown in fig. 2, the step of performing a splitting operation on the encoding parameter to obtain discrete point information includes: s131, judging whether the length of the coding parameter is larger than a preset value; s132, if the length of the coding parameter is larger than a preset value, splitting operation is carried out on the coding parameter to obtain discrete point information.
The length of the encryption parameter is in direct proportion to the length of the coding parameter, and the longer the length of the encryption parameter is, the less easily the encryption parameter is copied by people and the safer the encryption parameter is. The preset value can be set according to needs, and if the length of a general encoding parameter is greater than the preset value, it indicates that the encryption parameter corresponding to the encoding parameter is safe.
In one embodiment, the step of performing a splitting operation on the encoding parameters to obtain discrete point information includes: when the length of the coding parameter is larger than a preset value, intercepting data of the preset value length of the coding parameter; and carrying out splitting operation on the data with the preset value length to obtain discrete point information.
The data with the preset length is intercepted from the coding parameters, namely the data with the preset length is selected from the encryption parameters, the coding parameters with the preset length are easy to code, and after the data with the preset length of the coding parameters are coded, a user who inputs the encryption parameters can be informed to select the data with the preset length from the encryption parameters, so that the subsequent user can verify the encrypted watermark content of the personal electronic data picture.
In one embodiment, the watermark data processing method further includes: scanning the ciphertext watermark image to obtain an encryption parameter; the encryption parameter is used for verifying the authenticity of the personal electronic material picture.
The scanning terminal can be a terminal used by a data user, such as a mobile phone used by the data user. For example, the ciphertext watermark image is a two-dimensional code, the data user obtains an encryption parameter by scanning the two-dimensional code image, and judges whether the ciphertext watermark image is the correct data provided by the data provider according to the encryption parameter.
In one embodiment, the step of scanning the ciphertext watermark image to obtain an encryption parameter includes: scanning the ciphertext watermark image to obtain discrete point information; the discrete point information comprises the position of the discrete point in the personal electronic material picture and the RGB value of the discrete point; calculating to obtain coding parameters according to the positions of the discrete points in the personal electronic data pictures and the RGB values of the discrete points in the discrete point information; and calculating to obtain an encryption parameter according to the coding parameter.
The process of scanning the ciphertext watermark image to obtain the encryption parameters is opposite to the process of generating the ciphertext watermark image according to the encryption parameters. Scanning the ciphertext watermark image through a scanning terminal, and carrying out image processing on the ciphertext watermark image to obtain discrete point information; according to the position of the discrete point in the discrete point information in the personal electronic data picture and the RGB value of the discrete point, obtaining a coding parameter through combination operation calculation, wherein the calculation process of the combination operation is opposite to that of the splitting operation; and then, carrying out inverse coding according to the coding parameters to obtain the encryption parameters. The embodiment obtains the encryption parameters through scanning by the scanning terminal, and can be convenient for users to use.
In one embodiment, the step of scanning the ciphertext watermark image to obtain an encryption parameter includes: and scanning the ciphertext watermark image, and acquiring an encryption parameter according to an input encryption key.
The scanning terminal is used by a data user, and the data user can use the encryption parameter to authenticate the identity of the data user after obtaining the encryption parameter, for example, the data user is an insurance charging party and can indicate the identity of the data user according to the encryption parameter when charging is urged by a data provider; similarly, when receiving the insurance charging notification, the data provider can determine whether the data provider is the correct insurance charging party according to the encryption parameter provided by the other party. For example, after scanning the ciphertext watermark image, the scanning terminal displays prompt information for inputting the encryption key, the user inputs the encryption key according to the prompt information, and the scanning terminal decrypts the encryption parameter according to the encryption key.
The scanning terminal is a terminal used by a material provider, for example, the terminal used by the material provider is a mobile phone. In the case that the personal electronic material picture is leaked, the material provider can know who the personal electronic material picture is leaked by scanning the ciphertext watermark image of the leaked material to obtain the encryption parameter, because the encryption parameter has uniqueness, the material provider can set the unique encryption parameter when providing the personal electronic material picture with the encrypted watermark image, and can know the purpose of the personal electronic material picture according to the encryption parameter, and the material user who uses the personal electronic material picture as the purpose is also unique.
