Detailed Description
In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiment(s) may be practiced without these specific details.
Specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Example 1
In order to describe the image detection method based on the Hybrid App page watermark provided by the present invention, fig. 1 shows a flow of the image detection method based on the Hybrid App page watermark provided by the present invention.
As shown in fig. 1, the method for detecting an image based on a Hybrid App page watermark provided by the present invention includes: the method comprises an original watermarking process and a picture detection process, wherein the original watermarking process comprises the following steps:
s110: when the Hybrid App creates or jumps to a new page view, whether the new page view needs to be added with a watermark is judged based on a preset watermark adding file.
It should be noted that, in order to implement the watermark addition of the page view in the Hybrid App, when the Hybrid App is started, the system automatically and asynchronously pulls and updates the preset watermark addition file deployed by the server according to the service requirement. The watermark adding file comprises a name of a page to be added with a watermark (corresponding to the name of the page to be added with the watermark accurately according to service requirements), a page type corresponding to the name of the page to be added with the watermark, and a watermark adding style, wherein the page type comprises a Native page and an H5 page, and the watermark adding style comprises full page adding and sub-view adding.
Specifically, in the process of determining whether the new page view needs to be watermarked based on the watermark adding file, if the name of the new page view corresponds to any one of the names of the pages to be watermarked in the watermark adding file, it is determined that the new page view needs to be watermarked.
It should be noted that, in the process of actually displaying the page by the Hybrid App, the page is displayed one by one (i.e., the page is skipped to the next page from the current page), so that after the watermark adding file is pulled, the watermark adding file is analyzed in advance to analyze all information contained in the watermark adding file, mainly the name of the page to be added with the watermark, then when the Hybrid App creates or jumps to a new page view, whether the name of the page to be added with the watermark in the watermark adding file is consistent with the name of the new page view is directly judged, if so, it is judged that the new page view needs to be added with the watermark layer, and the watermark is added to the page according to the subsequent steps; if not, the new page view is judged not to need to be added with the watermark. Further, with the continuous adjustment of creating or jumping new page views by the Hybrid App, the addition of watermarks to most page views in the Hybrid App can be realized.
It should be further explained that whether the page view in the Hybrid App needs to be watermarked or not needs to be set according to the service needs, for example, if the service is mainly related to identification of the id card information, only the page view containing the id card information needs to be watermarked, and other types of page identification do not need to be watermarked. In addition, since the pictures uploaded to the preset detection server by the Hybrid App need to be called by the Hybrid App at least once in advance (in the process of creation or jumping), and since the pictures are necessarily displayed in the corresponding page view in the calling process, the addition of the corresponding watermarks can be realized on the pictures along with the addition of the page view watermarks, and when the detection server receives the pictures, the anti-counterfeiting identification detection can be performed based on the watermarks on the pictures.
S120: and if the new page view needs to judge the watermark, determining the page type of the new page view based on the watermark adding file, and configuring a corresponding watermark adding scheme for the new page view based on the page type, wherein the page type comprises a Native page and an H5 page.
Specifically, the page types of the Hybrid App mainly include a Native page and an H5 page, and the two types of pages have completely different attributes, so that the page types are easily distinguished, and a specific distinguishing method can select a packet capturing technology, a client display layout query mode and the like, wherein the packet capturing technology is used for judging whether the request has information of the html resource. The client display layout query is with the client's settings-display layout boundaries. Of course, there are other methods of differentiation, which are commonly used in the art, and the detailed description of the procedures is omitted here.
After the page type of the new page view is determined, a corresponding watermarking scheme can be configured for the new page view based on the page type. Specifically, if the page type of the new page view is a Native page, determining a watermark adding style of the new page view based on the watermark adding file;
if the watermark adding style of the new page view is full page adding, adding a corresponding watermark on the full page of the new page view according to the watermark adding scheme; and if the watermark adding style of the new page view is the sub-view adding, traversing all the picture sub-views in the new page view, selecting corresponding sub-views to be added and printed from all the picture sub-views based on a preset screening rule, and adding corresponding watermarks on the sub-views to be added and printed according to the watermark adding scheme.
If the page type of the new page view is the H5 page, configuring a corresponding watermarking scheme for the new page view based on the page type and adding a corresponding watermark to the new page view according to the watermarking scheme collectively include:
acquiring all picture sub-views in the new page view based on all img tags of the new page view;
selecting corresponding sub-views to be overprinted from all the sub-views of the picture based on the preset screening rule;
newly building Canvas, and using the sub-view to be overprinted as a bottom plate of the Canvas;
adding corresponding watermarks on the bottom plate of the Canvas according to the watermark adding scheme;
the Canvas is converted into an overprinted picture, and the overprinted picture is displayed back to the corresponding position of the new page view.
It should be noted that, in the process of obtaining all the picture sub-views in the new page view based on all the img tags in the new page view, getElementByTagName (a function) may be used to obtain the img tags first, and the getElementsByTagName () function can obtain the img tags from the H5 page and return the img tag class elements, where the order of the elements is the order of the elements in the document, and if a special character string "+" is passed to the getElementsByTagName () function, it will return the list of all the elements in the document, and the order of the elements arrangement is the order of the elements in the document, so all the img tags in the new page view can be obtained in sequence. While img tags are used to link images from the page (i.e., picture sub-views). Therefore, one img label corresponds to a picture sub-view in a new page view, and all picture sub-views in the H5 page can be obtained in this way.
More specifically, the preset screening rule includes:
judging whether the length and the width of each picture sub-view are both within a preset range;
and if one of the length and the width of the picture sub-view is not in the preset range, not setting the picture sub-view as the sub-view to be overprinted.
It should be noted here that, for the same new page view, since the sub-views of each picture have larger size difference, some of the sub-views are larger, and some of the sub-views are smaller, for the smaller sub-views, since the information implicit therein is substantially zero, the sub-views can be directly ignored, and the watermark is not added thereto, wherein the size of the preset range is set according to actual needs.
In addition, it should be emphasized that, in order to further ensure the privacy and security of the above-mentioned watermarking file and the data in the later-described watermark, both the watermarking file and the watermark may be stored in the nodes of the block chain.
S130: and adding the corresponding original watermark to the new page view according to the watermark adding scheme.
Specifically, the process of adding the corresponding watermark to the new page view according to the watermark adding scheme includes:
scaling the size of the watermark layers in an equal ratio according to the size of the new page view or the sub-view to be overprinted so as to set a preset number of watermark layers in the new page view or the sub-view to be overprinted;
adding a corresponding watermark in the watermark image layer; wherein the watermark is stored in a chain of blocks, and wherein the watermark comprises:
and the name, the current time, desensitized user account information and other information of the new page view.
More specifically, the watermark layer is a transparent watermark layer, and the corresponding watermarks are added in an interval oblique line manner, and the watermarks are added at four corner positions of the watermark layer.
The method can realize the addition of the watermark of the new page view or the sub-view to be overprinted, certainly, because the picture uploaded to the preset detection server by the Hybrid App needs to be called by the Hybrid App at least once in advance, and because the picture is necessarily displayed in the corresponding page view in the calling process, the addition of the corresponding watermark can be realized on the picture along with the addition of the page view watermark, and in the later period, when the detection server receives the picture, the anti-counterfeiting identification detection can be carried out based on the name of the new page view, the current time, the desensitized user account information and other information on the picture, and when the information passes the detection, the detection of the picture through the detection server can be judged.
In addition, in order to further improve the anti-counterfeiting detection effect of the picture, the watermark also comprises MD5 information; the MD5 information is obtained by RSA encrypting the name of the new page view, the current time, and the desensitized user account information.
It should be noted that, an MD5 Message Digest Algorithm (english: MD5 Message-Digest Algorithm), a widely used cryptographic hash function, can generate a 128-bit (16-byte) hash value (hash value) to ensure the Message transmission is complete and consistent. The programming of this set of algorithms is specified in the RFC 1321 standard. The algorithm has high safety, so that the algorithm is used as verification information to be arranged in the watermark image layer, and the anti-counterfeiting effect of the page can be obviously improved.
The picture detection process comprises the following steps: s140: and acquiring the picture to be detected uploaded by the Hybrid App through a preset detection server, and detecting whether the watermark of the picture to be detected is the original watermark or not based on a preset watermark detection rule, so as to realize the anti-counterfeiting identification detection of the picture to be detected.
It should be noted that after steps S110 to S130, the original watermarks of all page views or picture sub-views (the views include all pictures to be uploaded to the detection server) on the Hybrid App related to the detection service can be added, so that the anti-counterfeit identification detection can be performed on the picture to be detected based on the obtained watermark of the picture to be detected uploaded by the Hybrid App at a later stage.
Further, when the watermark includes MD5 information, the preset watermark detection rule may include: and analyzing the real watermark of the uppermost layer of the picture to be detected, identifying the information of the four corners of the watermark layer according to the analyzed real watermark of the uppermost layer, and finally calculating the MD5 value of RSA (picture name + time + account). Judging whether the calculated MD5 value is consistent with the MD5 of the preset original watermark; and if the picture to be detected is consistent with the picture to be detected, judging that the uploaded picture to be detected is real and effective, and if the picture to be detected is inconsistent with the picture to be detected, judging that the uploaded picture to be detected is invalid.
In addition, in order to further improve the anti-counterfeiting detection effect of the picture to be detected uploaded by the Hybrid App, the screenshot operation triggered by the Hybrid App can be monitored in real time, the current page view can be automatically drawn, then the corresponding watermark is added according to the steps, and the user album is cached.
According to the image detection method based on the Hybrid App page watermark, the watermark of the image in the Hybrid App is added in time in a mode of adding the watermark in the page of the Hybrid App, the preset detection server can conveniently check the image uploaded by the Hybrid App based on the watermark added by the image, and a user or even a third party is prevented from making fake on the aspects of processing and modifying the image in the process of uploading the image by the Hybrid App. In addition, by the scheme that the Hybrid App automatically updates the watermark adding file when the Hybrid App is started next time, the watermark meets the corresponding page scene, and the flexibility is high; in addition, when the user or the third party sees the relevant watermark layer, the intention of the user or the third party to continue to make a picture fake can be effectively reduced; meanwhile, by adding the calculation information (MD5 information and the like) of the watermark layer, the server can identify the vulnerability risk in the service approval process by checking the authenticity of the picture uploaded by the user again, improve the service risk level and ensure the normal operation of the service.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
