FIG. 2 schematically shows a flow chart of a page data protection method according to an embodiment of the disclosure.
As shown in fig. 2, the method includes operations S210 to S220.
In operation S210, in response to obtaining a request for saving page data, a user-specific watermark including handwriting is obtained. According to the embodiment of the disclosure, the handwriting comes from a user, and the user can electronize the handwriting through equipment such as a display canvas and the like so as to conveniently upload the handwriting to a network. And then generating a user-specific watermark according to the handwriting. For example, the user's handwriting may be generated by generating a canvas.
The generation canvas may be a client, an applet, or the like loaded on a user terminal device, and its generation file is readable to a terminal device or a server that executes the page data protection method. The generating canvas can support a straight line drawing method from a starting point to an end point, a cursor moves on the canvas, a plurality of points are determined from a moving track, and the plurality of points are connected in sequence to form the handwriting of the user. The generating canvas can also be set as an electronic device with a screen, a user can move on the screen by using an electronic pen and the like, a plurality of points are determined from a moving track, and the handwriting of the user can be formed by connecting the plurality of points in sequence.
In operation S220, the page data is processed based on the user-specific watermark to store the page data including the user-specific watermark, wherein the user is prohibited from storing the page data if the user-specific watermark including the handwriting is not successfully obtained. In this embodiment of the present disclosure, the processing of the page data based on the user-specific watermark may be to use the page data as a first image layer, use the user-specific watermark as a second image layer, and superimpose the first image layer and the second image layer, thereby obtaining the page data including the user-specific watermark, and a user may download the page data including the user-specific watermark. And if the user specific watermark fails to be acquired and the page data containing the user specific watermark cannot be acquired, the user is prohibited from downloading or storing the page data.
The method can prevent other users from imitating by setting the exclusive watermark of the user for the downloading user, can distinguish the identity of the downloading user, and sets the exclusive watermark of the user on the page data to be saved by the user, thereby protecting the own rights and interests of the downloading user and ensuring the rights and interests of companies.
Fig. 3 schematically shows a flow chart of a page protection method according to another embodiment of the present disclosure.
As shown in fig. 3, the method includes operations S310 to S340.
In operation S310, a save page data request is acquired. For example, the user downloads the data resources in the company database through the terminal device, and can acquire the request for saving the page data after clicking a save, download or save as another button.
In operation S320, a user-specific watermark is generated. The user-specific watermark may be a user's signature, job number, or user-defined symbol, etc. The user-specific watermark can be a user-specific watermark collected and preset by a company in a system, and at the moment, the pre-stored user-specific watermark is called after a user page data saving request is received. Or user-specific watermarks which are added by a user in real time after the user submits, clicks, saves or stores as buttons and are generated in real time according to the signature, the job number or the user-defined symbol and the like of the user.
The special watermark of the user can be made through a computer plug-in, a client or an applet and the like. For example, the Canvas is an added element of HTML5, and is used for drawing graphics on a webpage, and it is like a Canvas, and can be played on the Canvas as desired by JavaScript, so as to achieve the desired effect.
<canvas id＝"myCanvas″height＝"500px″width＝"500px″></canvas>
As indicated above, a Canvas tag may be defined in a page to obtain a Canvas const ctx ═ document, getelementbyid ("myccanvas"), getContext ("2 d"). Wherein ctx is the acquired canvas. Canvas provides a method of drawing a straight line, for example, defining two points, one being a start point and one being an end point, the coordinates of the start point being (0, 0), and the coordinates of the end point being (150, 0). Then, a cxt.stroke () command is executed to connect the start point and the end point into a straight line. According to the principle, a user can click points in a screen through a mouse in a certain sequence, the screen has countless points, the positions of clicking, dragging and lifting of the mouse are detected in real time in a code layer, and then the countless points are connected in sequence. As shown in fig. 4 and 5 below, fig. 4 schematically illustrates a schematic diagram with two-point handwriting according to an embodiment of the disclosure. FIG. 5 schematically shows a schematic diagram with multiple point handwriting in accordance with an embodiment of the disclosure. As shown in fig. 4, a start point (x, y) is defined, and an end point (m, n) can be connected between the two points to form a straight line. When a plurality of points are added between two points and connected in sequence, the handwriting as shown in the following figure 5 is generated. Although a straight line is still formed between every two points, the whole curve is formed, when n points are added between every two points and then the points are sequentially linked, the curve is curved in effect, a mouse can be used as a pen to draw a brush at will, and people know that the traditional signature with the pen has uniqueness, no matter whether the user signs a bill, uses a credit card and signs a contract, the traditional signature cannot be replaced by any other people because the handwriting of each person is unique. The mouse replaces a pen to realize various writing and drawing, and the uniqueness intention can be achieved. The thickness of the drawn stroke can also be adjusted by the lineWidth attribute, and the color of the brush can be adjusted by stroke style.
In operation S330, a user-specific watermark is disposed in the page data. In the embodiment of the present invention, the page data may be understood as an image layer, which is defined as a first image layer here. The user-specific watermark is understood to be a further layer, here positioned as the second layer. And arranging the second layer on the first layer. For example cs positioning may be used to position the user-specific watermark to the appropriate location of the page data.
In operation S340, it is determined whether the user-specific watermark is successfully arranged. And if the arrangement is successful, allowing the user to download the corresponding page data. For example, the page data carrying the user-specific watermark to be downloaded is acquired, and then the entire page data is converted into a Canvas object by using an html2Canvas library, and the web page can be converted into a document in a picture or pdf format by using a Canvas. If the arrangement is unsuccessful, the user is not allowed to download or issue a download failure command.
After the steps S310 to S340 are executed, the user can obtain the page data containing the user-specific watermark.
