[0082] The server 105 may be a server that provides various services, such as a background server that provides support for web pages displayed on the terminal devices 101 , 102 , and 103 .

[0083] It should be noted that the watermark processing method provided in the embodiment of the present application is generally executed by a server / terminal device, and accordingly, the watermark processing device is generally arranged in the server / terminal device.

[0084] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0085] Continue to refer Figure 2 , shows a flow chart of an embodiment of the watermark processing method according to the present application. According to different requirements, the order of the steps in the flow chart can be changed, and some steps can be omitted. The watermark processing method provided in the embodiment of the present application can be applied to any scenario where product recommendation is required, and the watermark processing method can be applied to products in these scenarios, for example, product recommendation in the financial insurance field. The watermark processing method comprises the following steps:

[0086] Step S201, obtaining watermark content to be processed.

[0087] In this embodiment, the electronic device (eg Figure 1The server / terminal device shown in the figure) can obtain the watermark content to be processed through a wired connection or a wireless connection. It should be pointed out that the above-mentioned wireless connection method may include but is not limited to 3G / 4G / 5G connection, WiFi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (ultra wideband) connection, and other wireless connection methods currently known or to be developed in the future. The above-mentioned watermark content to be processed is the watermark that needs to be filled in the target page. The above-mentioned target page refers to the page that needs to be processed with a watermark added to the above-mentioned watermark content. In the field of finance and insurance, the above-mentioned target pages may include auto insurance pages, claims pages, life insurance pages, and so on. Among them, the specific content of the watermark can be determined according to actual needs, such as simple patterns, etc. And due to the robustness of the blind watermark and user experience considerations, the watermark content should be as concise as possible.

[0088] Step S202: encrypt the watermark content based on a preset encryption algorithm to obtain corresponding first watermark content.

[0089] In this embodiment, the specific implementation process of encrypting the watermark content based on the preset encryption algorithm to obtain the corresponding first watermark content will be further described in detail in subsequent specific embodiments of the present application and will not be elaborated on here.

[0090] Step S203: performing grayscale conversion processing on the first watermark content to obtain corresponding second watermark content.

[0091] In this embodiment, the grayscale image conversion process of the first watermark content is performed to obtain the corresponding second watermark content. This application will further describe this in detail in the subsequent specific embodiments, and will not be elaborated on here. In addition, after obtaining the second watermark content, a matching HTTP cache header, such as Cache-Control and ETag, can be set for the second watermark content, so that the browser can cache the image and directly use the cached version in subsequent requests, reducing the number of server requests and bandwidth consumption.

[0092] Step S204: calling a pre-built watermark component.

[0093] In this embodiment, the watermark component is specifically a Web Components component. The structure of the watermark component is defined in advance using HTML and JavaScript, including creating a custom element corresponding to the watermark component and a shadow document object model of the watermark component, also known as Shadow DOM. The pre-built watermark component has the function of encapsulating the watermark element. After the construction of the watermark component is completed, the component mode needs to be configured. Including setting the grayscale mode: setting the component mode to grey-mode through JavaScript or HTML attributes. This mode can be a custom attribute or a state variable inside the component, which is used to instruct the watermark component to use a grayscale image to process the watermark. Optimizing performance processing: ensuring that the loading and rendering of the image are handled well inside the watermark component to optimize performance and user experience. In addition, the watermark component can also be processed asynchronously. Including asynchronous loading of components: if the watermark component depends on external resources (such as JavaScript libraries or style sheets), ensure that these resources are loaded asynchronously in advance to avoid blocking the rendering of the page. Asynchronous updates: If the watermark component needs to update content based on some asynchronous operations (such as data returned from the server), ensure in advance that these update operations will not block the main thread. In addition, you can also use performance analysis tools to monitor and debug the watermark component. Specifically, use the browser's developer tools (such as the Performance panel of Chrome DevTools) to monitor the performance of the watermark component. Analyze the loading time, execution time, and rendering time to find performance bottlenecks. And check the memory usage of the watermark component to ensure that there are no memory leaks. Then use the browser's memory analysis tool to track and fix the corresponding problems.

[0094] Step S205: creating a shadow document object model corresponding to the watermark element in the watermark component.

[0095] In this embodiment, the specific implementation process of creating the shadow document object model corresponding to the watermark element in the watermark component will be described in further detail in subsequent specific embodiments of the present application, and will not be elaborated on here.

[0096] Step S206: embed the second watermark content in the shadow document object model to obtain a corresponding target watermark component.

[0097] In this embodiment, the specific implementation process of embedding the second watermark content in the shadow document object model to obtain the corresponding target watermark component will be further described in detail in subsequent specific embodiments of the present application and will not be elaborated on here.

[0098] Step S207: Integrate the target watermark component into a preset target page.

[0099] In this embodiment, the specific implementation process of integrating the target watermark component into the preset target page will be described in further detail in subsequent specific embodiments of the present application, and will not be elaborated on here.

[0100] This application first obtains the watermark content to be processed; then encrypts the watermark content based on a preset encryption algorithm to obtain the corresponding first watermark content; then performs grayscale conversion on the first watermark content to obtain the corresponding second watermark content; subsequently calls a pre-built watermark component, and creates a shadow document object model corresponding to the watermark element in the watermark component; further embeds the second watermark content in the shadow document object model to obtain the corresponding target watermark component; finally, integrates the target watermark component into a preset target page. The present application generates a second watermark content by processing the acquired watermark content to be processed based on the use of an encryption algorithm and a grayscale image conversion method, and then uses a watermark component to create a shadow document object model corresponding to the watermark element, and embeds the second watermark content in the shadow document object model to obtain the corresponding target watermark component, and finally integrates the target watermark component into a preset target page, thereby realizing a safe and efficient blind watermark generation scheme, which can not only dynamically generate watermarks on web pages, but also effectively prevent watermarks from being tampered with, thereby providing strong support for the protection of watermark content, effectively solving the security problem of watermark generation, and ensuring the authenticity and credibility of the watermark content.

[0101] In some optional implementations, step S202 includes the following steps:

[0102] Determine the target encryption algorithm from multiple preset encryption algorithms.

[0103] In this embodiment, the encryption algorithm may include at least symmetric encryption algorithms such as DES algorithm, AES algorithm, etc., and asymmetric encryption algorithms such as RSA algorithm, DSA algorithm, ECC algorithm, etc. A symmetric encryption algorithm may be first determined from a variety of encryption algorithms because the symmetric encryption algorithm has a faster encryption and decryption speed. Then, an algorithm is randomly selected from all symmetric encryption algorithms as the target encryption algorithm.

[0104] Generate a key based on a preset encryption library.

[0105] In this embodiment, for the symmetric encryption algorithm, a key needs to be generated. This key will be used to encrypt and decrypt the watermark content. The key should be randomly generated and the length should be long enough to ensure security. Specifically, an encryption library (such as CryptoJS, OpenSSL, etc.) can be used to generate the key.

[0106] The watermark content is encrypted based on the target encryption algorithm and the key to obtain encrypted watermark content.

[0107] In this embodiment, the watermark content is encrypted by using the selected target encryption algorithm and the generated key. Specifically, the watermark content is used as the input of the target encryption algorithm, and the encrypted watermark content is output. The encrypted watermark content is random and has no obvious pattern, so as to protect the confidentiality of the watermark content.

[0108] The encrypted watermark content is used as the first watermark content.

[0109] The present application determines a target encryption algorithm from a plurality of preset encryption algorithms; then generates a key based on a preset encryption library; then encrypts the watermark content based on the target encryption algorithm and the key to obtain the encrypted watermark content; and subsequently uses the encrypted watermark content as the first watermark content. The present application uses a target encryption algorithm determined from a plurality of encryption algorithms and a key generated based on an encryption library to encrypt the watermark content, thereby achieving fast and accurate completion of the encryption processing of the watermark content, improving the processing efficiency of the encryption processing of the watermark content, and ensuring the confidentiality of the obtained first watermark content.

[0110] In some optional implementations of this embodiment, step S203 includes the following steps:

[0111] Obtain image display information of the first watermark content.

[0112] In this embodiment, the image display information of the first watermark content can be obtained by performing image analysis on the first watermark content. The image display information may include various information types such as binary images that are either black or white, grayscale images, color RGB images, RGBA images, etc. Among them, binary images that are either black or white: 1 bit can represent 1 pixel (two states of black and white). So 1 byte can represent 8 pixels. Grayscale image: 1 pixel has 256 states (2 to the 8th power), which requires 8 bytes, that is, 1 character. Color RGB image: There are three channels of R / G / B, each channel has 256 states, which are represented by 1 byte, and a total of 3 bytes are required to represent 1 pixel. RGBA image: On the basis of the three channels of R / G / B, a transparency channel is added, with 256 states, and an additional 1 byte is required, and a total of 4 bytes are required to represent one pixel.

[0113] Determine whether the image display information is grayscale image information.

[0114] In this embodiment, the image display information can be matched with the information corresponding to the grayscale image to obtain a corresponding matching result. If the matching result is a successful match, the image display information is determined to be grayscale image information, and if the matching result is a failed match, the image display information is determined not to be grayscale image information.

[0115] If not, a preset image processing tool is called to convert the first watermark content into a corresponding target grayscale image.

[0116] In this embodiment, the image processing tool may be image processing software or a programming library (such as Pillow for Python). If it is detected that the image display information is not grayscale information, the first watermark content is converted into a corresponding target grayscale image by the image processing tool.

[0117] The target grayscale image is used as the second watermark content.

[0118] In this embodiment, since the blind watermark does not need to support color and multi-color scenes, the first watermark content is converted into a corresponding target grayscale image, namely, the second watermark content, thereby effectively improving the processing speed and performance of the watermark processing.

[0119] The present application obtains the image display information of the first watermark content; then determines whether the image display information is grayscale information; if not, calls a preset image processing tool to convert the first watermark content into a corresponding target grayscale image; and subsequently uses the target grayscale image as the second watermark content. The present application obtains the image display information of the first watermark content, and when it is detected that the image display information is not grayscale information, intelligently calls an image processing tool to convert the first watermark content into a corresponding target grayscale image and uses it as the second watermark content, thereby effectively improving the processing speed and processing performance of watermark processing.

[0120] In some optional implementations, step S205 includes the following steps:

[0121] Gets the custom element corresponding to the watermark component.

[0122] In this embodiment, the watermark component is specifically a Web Components component. A custom element is predefined, which is the basis of Web Components. A custom element is a new element that inherits the HTMLElement class (or any class that inherits from HTMLElement) and is registered in the browser. A suitable element name can be determined according to actual business needs, such as <watermark-element>as the custom element above.

[0123] Construct a constructor corresponding to the custom element.

[0124] In this embodiment, a constructor is further written for the custom element in JavaScript, which initializes the custom element and prepares to attach the shadow document object model, namely Shadow DOM, to the constructor.

[0125] Gets the creation method of a preset.

[0126] In this embodiment, the above preset creation method can specifically adopt Element.attachShadow({mode:'open'}) or {mode:'closed'} method.

[0127] In the constructor, the shadow document object model corresponding to the watermark element is created using the creation method.

[0128] In this embodiment, in the constructor of the custom element, use Element.attachShadow({mode:'open'}) or {mode:'closed'} to create Shadow DOM. If you need to access Shadow DOM from external JavaScript, select the 'open' mode, or if you want better encapsulation and isolation, select the 'closed' mode. The 'closed' mode is preferred. In addition, after completing the construction of Shadow DOM, you also need to build an HTML structure in Shadow DOM to display the watermark. Specifically, you can create some DOM nodes (such as div, span, or img, etc.) and attach them to the root element of ShadowDOM. Among them, if you choose to use If you want to embed a grayscale watermark using the tag, you need to create an img element, set its src attribute to the URL of the watermark image, and then add it to the Shadow DOM. Alternatively, you can use other elements (such as canvas) to dynamically draw the watermark image. Finally, use the customElements.define() method to register the generated custom element to the browser. This method accepts two parameters: the name of the custom element (including the hyphen before the tag name) and the constructor of the custom element. And once the custom element is registered, you can use it in the HTML document like any other HTML element. Just change <watermark-element>(or any name you choose) to the corresponding HTML, the browser will automatically instantiate this element using the defined constructor and Shadow DOM.

[0129] Specifically, Shadow DOM will be used as the private DOM tree of the watermark element to encapsulate and isolate the HTML, CSS, and JavaScript code of the watermark content. After creating Shadow DOM, you can design the watermark content in Shadow DOM. Specifically, you can create an HTML element (such as 、 , , etc.) to carry the watermark content, and add CSS styles to it to control the display method (such as position, size, transparency, etc.). If you choose to use an image as the watermark content, you also need to include the image file as a resource in your web application and reference it through the src attribute in the HTML element.

[0130] The process of using Shadow DOM to achieve watermark isolation includes: 1. Use the Element.attachShadow method to attach the Shadow root to any element tree (Shadow T ree). 2. The element tree accepts the mode attribute, and the Shadow DOM can be obtained through the javascript method in the page. 3. Shadow DOM implements the close attribute, which achieves isolation by flattening the tree structure and exposing only the Shadow host to the outside.

[0131] The features of Shadow DOM include: 1. Encapsulation: Shadow DOM allows developers to encapsulate the internal structure, style, and behavior of components to isolate them from the external DOM tree. In this way, the internal implementation of the component will not be affected by external styles and scripts, nor will it affect other external elements. 2. Isolation: The styles and scripts defined in Shadow DOM are only valid for its internal elements, will not leak into external documents, and will not be affected by styles and scripts in external documents. This isolation helps reduce style conflicts and code pollution. 3. Scoped CSS: The style rules in Shadow DOM only apply to the internal elements of the component, which can avoid global style conflicts. It also allows common style class names to be used within the component without worrying about conflicts with class names in external documents.

[0132] The present application obtains a custom element corresponding to the watermark component; then constructs a constructor corresponding to the custom element; then obtains a preset creation method; and subsequently, in the constructor, uses the creation method to create the shadow document object model corresponding to the watermark element. The present application constructs a constructor corresponding to the obtained custom element corresponding to the watermark component, and then in the constructor, uses the obtained creation method to create the shadow document object model corresponding to the watermark element, thereby realizing the rapid and intelligent creation of the shadow document object model corresponding to the watermark element in the watermark component, thereby improving the creation efficiency and creation intelligence of the shadow document object model.

[0133] In some optional implementations, step S206 includes the following steps:

[0134] The second watermark content is embedded in the shadow document object model to obtain the corresponding first watermark component.

[0135] In this embodiment, by using the shadow document object model Tags or other suitable elements are used to embed the processed grayscale image watermark, that is, the above-mentioned second watermark content, so as to obtain the corresponding first watermark component.

[0136] Obtain a target display mode corresponding to the watermark content.

[0137] In this embodiment, the target display mode is to control the display mode of the watermark content. The specific display mode can be set according to the actual business use requirements.

[0138] Based on the target display mode, style processing is added in the shadow document object model in the first watermark component to obtain a corresponding second watermark component.

[0139] In this embodiment, the display mode of the watermark can be controlled by using CSS classes to define styles within Shadow DOM, that is, the above-mentioned target display mode. Specifically, the watermark display mode can be controlled by creating <style>元素并将其添加到Shadow DOM中来定义CSS样式。通过使用CSS类来控制水印的显示方式，而不是直接修改元素的style属性。这样可以利用浏览器的CSS优化机制，进而提高性能。
