Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The information era comes, application programs used by users are abundant, and users can communicate in a screenshot mode or a direct sharing mode, so that the contents which the users want to express can be expressed more accurately. However, the page data may include important information, and if a user modifies the important information by some means and issues some articles, unnecessary loss is caused, so that it is important to take measures to protect the page data. For example, for a certain shopping program, it is common that the user shares a page containing item prices, because price information is the most concerned content of the user, but price information is also very sensitive information. If the user modifies the price on the commodity page through some means and issues some articles, unnecessary loss is caused, and some price protection measures need to be taken on the commodity page, so that the loss can be reduced.
At present, for the page data with modified information, the picture can be scanned through professional picture analysis software to generate a binary code, and a damaged trace in the binary code is searched to determine whether the page data is modified once. For example, for a commodity picture with a modified price, the picture is scanned through professional picture analysis software to generate a binary code, and a damaged trace in the binary code is searched to determine whether the price of the commodity picture is modified once.
However, professional picture analysis software needs professional personnel to perform analysis operation, is difficult to implement, cannot respond quickly and determine the correctness of current shared page data due to too long search time, and cannot reduce the negative influence generated by modified content in time. In order to solve the above problem, an embodiment of the present invention provides a method for processing and verifying page data. The page data includes data to be protected, and the page data processing method can be used for processing the page data to generate a protection layer corresponding to the page data, so as to achieve the effect of protecting the data to be protected. The page data checking method can be used for processing the data processed by the page data processing method and analyzing the data needing to be protected in the original page data, so that whether the original page data is modified or not can be determined, the effect of protecting the page data is achieved, and the loss caused by data modification is reduced.
Fig. 1 is a schematic diagram of main steps of a page data processing method according to an embodiment of the present invention, and as shown in fig. 1, the page data processing method according to the embodiment of the present invention may include:
step S101: acquiring page data to be processed according to the page data processing request, and extracting data to be protected in the page data to be processed;
step S102: based on a color deepening algorithm, generating a protection layer corresponding to the page data to be processed according to the page data to be processed and the data to be protected;
step S103: and adding the protection layer corresponding to the page data to be processed into the sub-image layer of the page data to be processed so as to complete the processing of the page data.
It can be seen that in the method for processing page data in the embodiment of the present invention, data to be protected needs to be extracted from the page data to be processed, for example, the page data to be processed is a page that includes item price information and is shared by a user, and then the data to be protected is the item price information. And after the data to be protected is extracted, processing the page data to be processed and the data to be protected by combining a color deepening algorithm principle to obtain a protection layer corresponding to the page data to be processed. And finally, adding the obtained protection layer into a sub-graph layer of the page data to be processed, wherein the sub-graph layer can be the topmost layer of the page data to be processed, and the page data intercepted or shared by a user comprises the generated protection layer, so that the processed page data can be protected to the data needing to be protected in the page data.
In consideration of the technical scheme of processing and verifying the page data in the embodiment of the invention, the technical scheme is based on the color deepening algorithm, so that the color deepening algorithm is introduced for convenience of understanding. The RGB color scheme is a color standard in the industry, and various colors are obtained by changing three color channels of red (R), green (G) and blue (B) and superimposing the three color channels, and currently, the RGB color standard is adopted for displaying various colors on page data. Wherein, white is RGB (255 ), black is RGB (0, 0), if white RBG (255 ) three color channels subtract 1 to get RGB (254 ), and can not distinguish the color value difference of RGB (254 ) and RGB (255 ) with naked eyes. If the three color channels of black RBG (0, 0) are added with 1 respectively, RGB (1, 1) is obtained, and it is visually indistinguishable from black RGB (1, 1) by the naked eye. Since white is RGB (255 ), and the difference between RGB (254 ) and white is 1, RBG (255 ) and RGB (254 ) are visually indiscriminate and can be regarded as white, and similarly, since the difference between black RGB (0, 0) and RGB (1, 1) is 1, RGB (1, 1) and RGB (0, 0) color values are visually indiscriminate and can be regarded as black.
The color deepening algorithm is a mixed mode in computer world image software Adobe photoshop, and the specific color deepening algorithm formula is as follows:
primary color- ((255-primary color x (255-mixed color))/mixed color ═ result color
Assuming that the primary colors are (255, 254, 255), the mixed colors are (1, 2, 3), the value of the R channel in the obtained result color is 255- ((255-.
If white RGB (255 ) is used as the primary colors and black RGB (1, 1) is used as the mixed color, the resultant color obtained by the color deepening algorithm formula is RGB (255 ) that is white, and if white RGB (254 ) is used as the primary colors, black RGB (1, 1) is used as the mixed color and the resultant color obtained by the color deepening algorithm formula is RGB (0, 0) that is black. Therefore, RGB (255 ) and RGB (254 ) are known to have a large contrast with the resultant color obtained by color deepening RGB (1, 1). Fig. 2 is a schematic diagram of the effect obtained by the color deepening algorithm, in fig. 2, the upper left corners of the primary colors are white RGB (254 ), and the other regions are white RGB (255 ), and it can be known from the above analysis that the upper left corners of the white RGB (254 ) and the other regions of the white RGB (255 ) are not distinguishable by naked eyes. The mixed color in fig. 2 is black RGB (1, 1), the upper left corner of the resulting color is black RGB (0, 0), and the other regions are white RGB (255 ). Therefore, in the method for processing page data of the embodiment of the present invention, the protection layer corresponding to the page data to be processed and the page data to be processed may be mixed, so that the information of the data to be protected on the protection layer is superimposed on the white area of the page data to be processed, and then the color is white RGB (254 ), and the color is white RGB (255 ), and then in the method for verifying page data, the color deepening operation is performed on the processed page data and the black RGB (1, 1), and then the data to be protected may be displayed.
The analysis shows that the generation of the protection layer corresponding to the page data to be processed based on the color deepening algorithm is an important starting point of the embodiment of the invention. Therefore, as a reference embodiment of the present invention, generating a protection layer corresponding to the page data to be processed according to the page data to be processed and the data to be protected based on the color deepening algorithm may include:
step S1021: generating a background layer corresponding to the page data to be processed according to the size information of the page data to be processed;
step S1022: setting the color of the background layer as a first black color and setting the transparency of the background layer as a first transparency based on a color deepening algorithm;
step S1023: generating drawn text data corresponding to the data to be protected, setting the color of the drawn text data to be first black based on a color deepening algorithm, and setting the transparency of a background layer to be second transparency;
step S1024: and generating a protection layer corresponding to the page data to be processed according to the background layer and the drawn text data.
According to the analysis, in the protection layer corresponding to the generated page data to be processed, the protection layer corresponding to the data to be protected and the white data of the page data to be processed are superimposed to form white RGB (254 ), and the protection layers corresponding to other data and the white data of the page data to be processed are superimposed to form white RGB (255 ). Therefore, in step S1021, a layer with the same size as the page data to be processed is created through the provided layer drawing capability, the generated layer is a background layer corresponding to the page data to be processed, then the color of the background layer is set to be the first black RGB (0, 0), and the transparency of the background layer is set to be the first transparency 0, that is, there is no background color, so that the generated background layer and the white area of the page data to be processed are overlapped to be the white RGB (255 ), and the purpose of not affecting the visual effect of the page data to be processed can be achieved. In order to make the white data of the page data to be processed and the protection layer corresponding to the data to be protected superposed into white RGB (254 ), it is necessary to generate rendering text data corresponding to the data to be protected, set the color of the rendering text data to be first black RGB (0, 0), and set the transparency of the background layer to be second transparency 0.002, and the set color value and transparency are superposed with other colors without causing visual influence on other colors, so that the white RGB (254 ) obtained by superposing the white areas of the rendering text data and the page data to be processed can be satisfied, and the visual effect can be not influenced. And finally, drawing text data corresponding to the data to be protected into a background layer corresponding to the page data to be processed, so that a protection layer corresponding to the page data to be processed can be obtained.
In addition, in view of the fact that in the page data processing method according to the embodiment of the present invention, white RGB (254 ) is obtained after the drawn text data corresponding to the to-be-protected data is superimposed on the white area of the to-be-processed page data, and in view of the fact that positions of the white areas of different page data are different, it is necessary to draw a plurality of drawn text data corresponding to the to-be-protected data in the background layer, in the embodiment of the present invention, generating the protection layer corresponding to the to-be-processed page data according to the background layer and the drawn text data may include: and drawing the drawn text data on the background layer according to a multi-row and multi-column mode to obtain a protection layer corresponding to the page data to be processed.
For example, fig. 3 is a schematic diagram taking page data as an article page as an example, it can be seen that the article page displays many information contents related to an article, such as an article picture, preferential information, a title, a price, and the like, data to be protected is price information, it should be noted that the price information in the schematic diagrams of fig. 3, 4, and 7 is retained, and other information is fuzzified. It can also be found by observing fig. 3 that multiple regions of the article page are blank, so that it can be known from the above analysis principle that the drawn text data corresponding to the price information to be drawn intersects with the white region of the article page, and therefore drawn text data corresponding to multiple rows and multiple columns of price information need to be drawn on the background layer corresponding to the article page, so that drawn text data corresponding to multiple price information is drawn as shown in fig. 4, where fig. 4 is a schematic diagram of drawn text data corresponding to price information of an article, taking page data as an example of the article page. It should be noted that fig. 4 is only a schematic diagram, because the color RGB (0, 0) of the rendered text data corresponding to the rendered price information has a transparency of 0.002, and the rendered content is not actually seen by naked eyes, fig. 4 is to show the rendered text data in black for clearly observing the rendered text data corresponding to the price information.
Therefore, as another referential embodiment of the present invention, before extracting the data to be protected in the page data to be processed, the page data processing method may further include: and judging whether the page data to be processed comprises data needing to be protected or not, and if so, determining the data needing to be protected as the data to be protected. That is, after the page data to be processed is obtained, it is necessary to determine whether the page data to be processed includes data that needs to be protected, if so, the data that needs to be protected may be directly determined as the data that needs to be protected, and then a protection layer of the data that needs to be processed is generated, and if it is known that there is no data that needs to be protected, then subsequent processing is not required.
Fig. 5 is a schematic diagram of a main flow of a page data processing method according to an embodiment of the present invention. As shown in fig. 5, the main flow of the page data processing method according to the embodiment of the present invention may include:
step S501: acquiring page data to be processed according to the page data processing request;
step S502: judging whether the page data to be processed includes data needing protection, if so, executing a step S503;
step S503: determining data needing to be protected as data to be protected, and extracting the data to be protected;
step S504: generating a background layer corresponding to the page data to be processed according to the size information of the page data to be processed, setting the color of the background layer to be first black RGB (0, 0) based on a color deepening algorithm, and setting the transparency of the background layer to be first transparency 0;
step S505: generating drawing text data corresponding to the data to be protected, setting the color of the drawing text data to be first black RGB (0, 0) based on a color deepening algorithm, and setting the transparency of the drawing text data to be second transparency 0.002;
step S506: drawing the drawn text data on a background layer according to a multi-row and multi-column mode to obtain a protection layer corresponding to the page data to be processed;
step S507: and adding the protection layer corresponding to the page data to be processed into the sub-image layer of the page data to be processed so as to complete the processing of the page data.
It should be noted that the execution order of the step S505 and the step S506 may be adjusted, the step S506 may be executed first, and then the step S505 is executed, or the step S505 and the step S506 may be executed simultaneously, which is not limited herein.
According to the processing scheme of the page data, the data to be protected in the page data to be processed can be obtained, then the protection layer without visual perception is generated by combining the color deepening algorithm, the protection layer is added into the layer of the page data to be processed, the effect of protecting the page data is achieved, and meanwhile the display of the page data is not influenced.
The verification method of the page data in the embodiment of the present invention corresponds to the processing method of the page data in the embodiment of the present invention, and the page data processed by the processing method of the page data in the embodiment of the present invention may be verified by the verification method of the page data in the embodiment of the present invention. In short, the page data to be verified in the page data verification request of the embodiment of the present invention is the page data processed according to the page data processing method of the embodiment of the present invention. For example, after the item page is processed by the page data processing method, a user shares the processed item page to other users through screenshot or other manners, and the other users modify the obtained price information on the item page and then use the item page with the modified price information for other purposes, which may cause loss. Fig. 6 is a schematic diagram of main steps of a verification method of page data according to an embodiment of the present invention. As shown in fig. 6, the main steps of the method for checking page data according to the embodiment of the present invention may include:
step S601: acquiring page data to be verified according to a page data verification request, and extracting at least one pixel point corresponding to the page data to be verified, wherein the page data to be verified is obtained by processing the page data according to the page data processing method of the embodiment of the invention;
step S602: based on a color deepening algorithm, generating comparison page data corresponding to the page data to be verified according to at least one pixel point and the second black;
step S603: and comparing and checking the page data to be checked and the comparison page data to obtain a checking result so as to complete checking of the page data.
In the verification method of the page data of the embodiment of the invention, the page data to be verified is firstly obtained, and then each pixel point corresponding to the page data to be verified is extracted. As can be seen from the above analysis of the color deepening algorithm, in the method for processing page data according to the embodiment of the present invention, the protection layer corresponding to the page data to be processed and the page data to be processed may be mixed, so that the information of the data to be protected on the protection layer is white RGB (254 ) after being superimposed with the white area of the page data to be processed, the information except the data to be protected on the protection layer is white RGB (255 ) after being superimposed with the white area of the page data to be processed, then in the page data checking method, the processed page data and black RGB (1, 1) are processed to perform color deepening operation, so that the data to be protected can be displayed, therefore, in step S602, a color deepening algorithm is performed on each pixel point and the second black RGB (1, 1), so that comparison page data corresponding to the page data to be verified can be generated. And finally, the page data to be verified and the generated comparison page data can be compared and verified, and finally, a verification result is obtained, so that the verification of the page data can be completed.
It can be seen that the generation of the comparison page data in the verification method of the page data of the embodiment of the invention is a main innovation point. As another reference embodiment, based on the color deepening algorithm, generating comparison page data corresponding to the page data to be verified according to at least one pixel point and the second black color, may include:
step S6021: determining a new color value corresponding to each pixel point according to the color value of each pixel point and the second black color according to a color deepening algorithm;
step S6022: and replacing the position of the color value of each pixel point in the page data to be verified by using the new color value corresponding to each pixel point, and generating comparison page data.
In the embodiment of the present invention, determining a new color value corresponding to each pixel point according to the color value of each pixel point and the second black color according to a color deepening algorithm may include: setting the color value of each pixel point as a primary color, and setting a second black color as a mixed color; and substituting the set primary colors and the set mixed color into a color deepening algorithm formula to obtain a result color, and determining the result color as a new color value corresponding to each pixel point.
After the page data to be verified is obtained, analyzing the color value RGB of each pixel point on the page data to be verified, taking the obtained color value RGB of each pixel point as a primary color and a mixed color RGB (1, 1) to perform a color deepening algorithm, and obtaining a result color which is a new color value RGB corresponding to each pixel point. And then, the new color value can replace the position of the pixel point principle color value, and the obtained new page data is comparison page data corresponding to the data to be verified. Fig. 7 is a schematic diagram of comparison page data generated by taking page data as an article page as an example. As can be seen from fig. 7, the drawn text data corresponding to the price information corresponding to the item page is displayed on the comparison page data in a dark-colored result color, and in addition, because each pixel on the data to be verified is subjected to a color deepening algorithm, a black item image appears, which also shows the advantage that the drawn text data corresponding to the data to be protected is drawn into the background image layer in a multi-row and multi-column manner in the page data processing method of the embodiment of the present invention, so that the data to be protected can be prevented from being covered, and the data to be protected can be accurately acquired.
In addition, in the embodiment of the present invention, comparing and verifying the page data to be verified and the comparison page data to obtain the verification result, the comparing and verifying may include: extracting data to be protected in the page data to be processed, and extracting dark color result data in the page data to be compared; and judging whether the data to be protected is the same as the dark color result data, if so, confirming that the data to be protected is not processed, and if not, confirming that the data to be protected is processed.
It can be known that the drawn text data generated by the page data processing method of the embodiment of the present invention on the data to be protected in the page data is the dark color result data in the comparison page data obtained by the page data verification method of the embodiment of the present invention, so that the dark color result data and the data to be protected can be compared, if the dark color result data and the data to be protected are the same, the data to be protected is considered to be not processed, otherwise, the data to be protected is considered to be processed. This is because the protection layer generated in the page data processing method of the embodiment of the present invention is a layer that cannot be seen with naked eyes, and therefore, even if a user modifies page data, there is no way to modify the layer that cannot be seen with naked eyes, so that data that needs to be protected can be known by comparing dark color result data in the page data, and the data that needs to be protected is compared with data to be protected visually displayed in the page data to be verified, so that the correctness of the page data to be verified can be quickly located.
