Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, a schematic diagram of a system architecture according to the technical scheme of the present application is shown. The system architecture may include: a provider device 11, a content platform 12 and a consumer device 13.
The provider device 11 refers to a device used by a provider of display content for generating and distributing the display content to the content platform 12 so that consumers acquire the display content from the content platform 12 for viewing. The provider device 11 may be an electronic device such as a PC (Personal Computer ) or a server.
The content platform 12 is for receiving display content from the provider device 11 and providing the display content to the consumer device 13. The content platform 12 is an independent physical server, may be a server cluster or a distributed system formed by a plurality of physical servers, or may be a cloud server providing cloud computing services.
Consumer device 13 refers to a device that obtains and presents the display content described above. The consumer device 13 is used by a consumer (also referred to as a user) displaying content, and the consumer device 13 may be an electronic device such as a cell phone, tablet computer, multimedia player device, wearable device, PC, etc., which is not limited in this embodiment of the present application.
The content platform 12 may communicate with the provider device 11 and the consumer device 13, respectively, over a network.
Optionally, as shown in fig. 1, the system architecture may further include: a database 14.
Database 14 may be used to store some data related to the display content in content platform 12, such as the display content itself or some associated data.
The content platform 12 may interface with the database 14, be able to store data into the database 14, and also be able to retrieve desired data from the database 14.
In a typical application scenario, the system architecture shown in fig. 1 may be implemented as a publication and presentation system for a web page. The provider device 11 may be a device used by a developer of a web page, and the developed web page may be released to the content platform 12 for storage, and the consumer device 13 may obtain the web page from the content platform 12 and display the web page when necessary.
Of course, the display content provided in the embodiments of the present application may be a web page, or any other content capable of being displayed on a device, such as text, pictures, video, or other data, which is not limited in the embodiments of the present application.
In addition, the content platform 12 may be considered a server for providing services to clients, such as distribution and presentation of content. The client of the consumer device 13 may install a target application program, which may be a browser, or any application program with content display requirements, such as an IM (Instant Messaging ) application, a social application, a network purchase application, a video application, and the like. Correspondingly, the server is a background server of the target application program and is used for providing background service for the client.
In the technical scheme provided by the embodiment of the application, in the process of generating the content information of the target display content, segmenting the content data of the target display content, determining the identification of each data segment, and adding the identification of each data segment into the content information; accordingly, in the analysis process of the target display content, after the content data is segmented, whether the identification of each data segment is accurate or not is checked, and the data segment with inaccurate identification is regarded as a problem data segment to be removed, so that even if malicious tampering occurs in the analysis process, the malicious tampering can be successfully detected through checking the accuracy of the identification, a better tamper-proof effect is achieved, and normal display of the target display content is ensured as much as possible.
The following describes the technical scheme of the application through several embodiments.
Referring to fig. 2, a flowchart of a content generation method according to an embodiment of the present application is shown, and the method may be applied to the content platform 12 of the system architecture shown in fig. 1. The method may comprise the following steps (201-204):
in step 201, content data of target display content is acquired.
The target display content may be a web page, or any other content that can be displayed on a device, such as text, pictures, video, or other data, which is not limited in this embodiment of the present application.
The content data of the target display content refers to data included in the target display content, that is, data to be displayed by the target display content. Taking the target display content as a target web page for example, the content data of the target display content includes a web page file of the target web page, such as an HTML (HyperText Mark-up Language) file. The content data of the target display content may be a file in text form or a file in non-text form, which is not limited in the embodiment of the present application.
Step 202, dividing the content data into a plurality of data segments.
Each data segment is a part of data in the content data. In the embodiment of the present application, the content data is divided into a plurality of data segments, and the lengths (such as the contained data amounts or the character amounts) of the respective data segments may be the same or different.
In one example, content data is partitioned into a plurality of data segments according to a specified partitioning rule. The specified division rule refers to a predetermined rule for segmenting the content data. Optionally, the specified partitioning rule is a partitioning rule agreed between the provider and the consumer of the target display content. That is, both the provider and the consumer of the target display content need to learn the specified partitioning rule, and the provider segments the content data of the target display content by adopting the specified partitioning rule in the process of generating the content information of the target display content; accordingly, the consumer also employs the specified partitioning rule to segment the content data of the target display content during the process of displaying the target display content. Therefore, the provider and the consumer can adopt the same division rule to carry out the segmentation operation on the content data, and the consistency of the provider and the consumer in the segmentation mode is ensured.
In another example, in a case where the target display content is a target web page, the content data of the target display content includes a web page file of the target web page, the web page file is divided into a plurality of data pieces in units of web page tags. Wherein each data segment corresponds to a web page tag. For example, if a web page file includes 100 web page tags, the web page file may be divided into 100 data segments, each corresponding to a web page tag. The webpage elements lead the text out of the document through webpage tags, and the webpage tags consist of elements wrapped in "<" and ">". In addition, the web page tag can contain attributes for describing the web page tag, and support developer custom attributes. Web page tags may also be referred to as HTML tags.
Of course, in some other examples, a plurality of web page tags may be divided into one data segment, so long as the provider and the consumer are guaranteed to use the same division rule to perform the segmentation operation on the web page file, which is not limited in the embodiment of the present application.
Step 203, determining the segment identifier of each data segment, and determining the segment identifier as the first segment identifier.
After segmenting the content data, a first segment identification of each data segment is determined. In the embodiment of the present application, the segment identifier generated by the provider is referred to as a first segment identifier, and the segment identifier generated by the consumer is referred to as a second segment identifier.
In one example, the first segment identity of each data segment is the same. For example, a random string may be generated that is identified as the first segment of each data segment. Alternatively, a predetermined fixed string may be selected as the first segment identifier of each data segment. The adoption of the random character string as the segment identifier is relatively higher in safety and is not easy to crack or forge compared with the adoption of the fixed character string as the segment identifier.
In another example, the first segment identification of each data segment is different. Optionally, generating a random string corresponding to the target display content, for a target data segment in the content data, splicing the random string with the target data segment to obtain spliced data, and determining a hash value of the spliced data as a first segment identifier of the target data segment. Assuming that a random character string corresponding to target display content is S, a target data segment is A, splicing the random character string S and the target data segment A to obtain spliced data A1, calculating a Hash value F1 of the spliced data A1 by adopting a Hash algorithm, and taking the F1 as a first segment identifier of the target data segment A. The Hash algorithm is adopted to calculate the segment identification of the data segment, so that on one hand, the controllable length of the segment identification can be ensured, the overlong length of the segment identification is avoided, and on the other hand, the uniqueness of the segment identification can be ensured, and the Hash values generated by the Hash algorithm aiming at different data are different, so that the difficulty of cracking or forging the segment identification can be further improved. In addition, in the embodiment of the present application, the specific type of the Hash algorithm is not limited, such as SHA256 (Secure Hash Algorithm ) algorithm, MD5 (Message Digest) algorithm, and the like, which is not limited in the embodiment of the present application.
In addition, the random character string referred to in the embodiment of the present application refers to a character string that is randomly generated, for example, a character string generated by a random number generator. The random string may include at least one of a number, a letter, and a symbol.
In addition, the method of splicing the random string and the target data segment may be to splice the random string at the head of the target data segment, splice the random string at the tail of the target data segment, or splice the random string at the middle of the target data segment. Optionally, according to a specified splicing rule, splicing the random character string with the target data segment to obtain spliced data. The specified splicing rules are predetermined rules for splicing the random character strings and the data fragments. Optionally, the specified splice rule is a splice rule agreed between the provider and the consumer of the target display content.
In addition, the target data segment may be any one of a plurality of data segments divided from the content data, and any one of the data segments may determine the corresponding first segment identifier in the manner described above.
In step 204, content information of the target display content is generated, where the content information includes content data and the first segment identifier used for verifying the content data.
Alternatively, the first segment identification of each data segment may be added to the content information of the target display content as attribute information of the target display content. If the first segment identifiers of the respective data segments are identical, only one first segment identifier need be included in the content information. If the first segment identifications of the respective data segments are different, then the content information needs to include the respective first segment identifications of the respective data segments. Alternatively, the first segment identifications of the respective data segments may be recorded in the content information in order of the data segments so that the consumer can determine what the first segment identification of each data segment is; alternatively, the data segments may be numbered and then the number of the data segment is recorded in the content information in correspondence with the first segment identification thereof.
In addition, if the random character string corresponding to the target display content is generated, the correspondence between the identification information of the target display content and the random character string may be stored in the database, so that the consumer can acquire the random character string corresponding to the target display content for use in verification.
Alternatively, in some other examples, a random string may be added to the content information, which does not require an additional database, but the random string may be obtained directly after the content information is obtained, resulting in a reduced difficulty in obtaining the random string. In practical applications, a suitable manner may be selected to provide the random string to the consumer in conjunction with the actual requirement, which is not limited in this embodiment of the present application.
In summary, according to the technical scheme provided by the embodiment of the application, in the process of generating the content information of the target display content, the content data of the target display content is segmented, the segment identifiers of all the data segments are determined, and the segment identifiers of all the data segments are added to the content information, so that a consumer can determine the problem data segment which is maliciously tampered by the consumer by checking whether the segment identifiers of all the data segments are accurate in the process of analyzing the target display content, and even if the malicious tampering occurs in the process of analyzing, the problem data segment can be successfully detected by checking the accuracy of the segment identifiers, thereby achieving a better tamper-proof effect and ensuring the normal display of the target display content as much as possible.
In addition, after the random character string is generated and the data fragments are spliced, the corresponding fragment identification is obtained by carrying out Hash calculation on the spliced data, so that on one hand, the length of the fragment identification can be ensured to be controllable, the length of the fragment identification is not too long, and on the other hand, the uniqueness of the fragment identification can be ensured, and because Hash values generated by a Hash algorithm aiming at different data are different, the fragment identification generated by combining the Hash algorithm with the random character string has the characteristic of non-forging, and the hijacking party can be prevented from cheating and checking by forging the fragment identification or using legal fragment identifications of other data fragments, thereby further improving the safety.
In addition, the content data is segmented by fine granularity, for example, a single webpage label is used as granularity for a webpage file, and a segment identifier is added to each webpage label, so that the condition that a hijacking party falsifies original normal content to cause large-area webpage content to be identified as illegal content and removed can be prevented, and the influence of hijacking is reduced.
Referring to fig. 3, a flowchart of a content display method according to an embodiment of the present application is shown, and the method may be applied to the consumer device 13 of the system architecture shown in fig. 1. The method may comprise the following steps (301-306):
Step 301, obtaining content information of a target display content, wherein the content information comprises content data of the target display content and at least one first segment identifier for verifying the content data.
For description of the content information about the target display content, refer to the embodiment of fig. 2, which is not described in detail in this embodiment.
The consumer device may actively obtain the target display content from the content platform, e.g., upon receiving a display instruction for the target display content, the consumer device requests the content platform to obtain content information for the target display content. Alternatively, the content platform may actively push the target display content to the consumer device, e.g., the content platform sends content information of the target display content to the consumer device when the set push condition is satisfied.
Step 302, the content data is divided into a plurality of data segments.
After the content information of the target display content is acquired, the content data of the target display content is acquired therefrom, and then the content data is segmented. Each data segment is a part of data in the content data. In the embodiment of the present application, the content data is divided into a plurality of data segments, and the lengths (such as the contained data amounts) of the respective data segments may be the same or different.
In one example, the content data is partitioned into a plurality of data segments according to a specified partitioning rule. The specified division rule refers to a predetermined rule for segmenting the content data. Optionally, the specified partitioning rule is a partitioning rule agreed between the provider and the consumer of the target display content. That is, both the provider and the consumer of the target display content need to learn the specified partitioning rule, and the provider segments the content data of the target display content by adopting the specified partitioning rule in the process of generating the content information of the target display content; accordingly, the consumer also employs the specified partitioning rule to segment the content data of the target display content during the process of displaying the target display content. Therefore, the provider and the consumer can adopt the same division rule to carry out the segmentation operation on the content data, and the consistency of the provider and the consumer in the segmentation mode is ensured.
In another example, in a case where the target display content is a target web page, the content data of the target display content includes a web page file of the target web page, the web page file is divided into a plurality of data pieces in units of web page tags. Wherein each data segment corresponds to a web page tag. For example, if a web page file includes 100 web page tags, the web page file may be divided into 100 data segments, each corresponding to a web page tag. The webpage elements lead the text out of the document through webpage tags, and the webpage tags consist of elements wrapped in "<" and ">". In addition, the web page tag can contain attributes for describing the web page tag, and support developer custom attributes. Web page tags may also be referred to as HTML tags.
Step 303, determining the segment identifier of each data segment, and determining the segment identifier as the second segment identifier.
After segmenting the content data, a second segment identification of each data segment is determined. In the embodiment of the present application, the segment identifier generated by the provider is referred to as a first segment identifier, and the segment identifier generated by the consumer is referred to as a second segment identifier.
In one example, the second segment identity of each data segment is the same. For example, in the case that the second segment identifiers of the data segments are the same and are random character strings, the consumer device obtains the random character string corresponding to the target display content as the second segment identifier. In addition, if the identifiers of the data segments are the same and are all fixed character strings, the consumer device acquires the fixed character strings as the second segment identifiers.
Alternatively, if the random character string is stored in the database, the random character string corresponding to the target display content may be acquired from the database. The database stores the corresponding relation between the identification information of the target display content and the random character string. For example, the consumer device may send a request separately to the content platform, such as a so-called string acquisition request, where the string acquisition request is used to request to acquire a random string corresponding to the target display content, where the string acquisition request may include identification information of the target display content, and after receiving the string acquisition request, the content platform acquires the random string corresponding to the target display content from the database and sends the random string to the consumer device. Of course, in some other embodiments, the consumer device may also directly request to obtain the random string corresponding to the target display content from the database, or obtain the random string corresponding to the target display content through other ways, which is not limited in the embodiments of the present application.
Alternatively, if the random string is added to the content information, the consumer device may directly obtain the random string corresponding to the target display content from the content information of the target display content.
In another example, the second segment identification of each data segment is different. Optionally, the step 303 may include the following sub-steps:
1. acquiring a random character string corresponding to target display content;
2. for a target data segment in the content data, splicing the random character strings with the target data segment to obtain spliced data;
3. and determining the hash value of the spliced data as a second segment identifier of the target data segment.
As shown in fig. 4, assuming that the random string corresponding to the target display content is S, the target data segment is a, the spliced data obtained by splicing the random string S and the target data segment a is A2 (in the case that the target data segment a is not tampered, the A2 should be the same as A1 in the embodiment of fig. 2, but if the target data segment a is tampered, the A2 is different from the A1), then a Hash algorithm is used to calculate a Hash value F2 of the spliced data A2, where the F2 is the second segment identifier of the target data segment a.
In addition, when the random character string is spliced with the target data segment, the splicing mode adopted between the provider and the consumer of the target display content should be consistent, so as to ensure the consistency between the provider and the consumer and the accuracy of the verification result aiming at the identification.
In addition, the target data segment may be any one of a plurality of data segments divided from the content data, and any one of the data segments may determine the corresponding second segment identifier in the manner described above.
Step 304, for the target data segment in the content data, checking whether the target data segment belongs to the problem data segment according to the first segment identifier and the second segment identifier of the target data segment.
In the embodiment of the application, the data segments are checked based on the segment identifiers to determine whether each data segment belongs to a problem data segment. The problem data segments refer to original data segments provided by a provider, and may be data segments after the original data segments are modified by a third party or data segments newly added by the third party, and the problem data segments may carry information such as advertisements, fraud and the like, so that the normal display and the security of target display content are affected.
In one case, if the first segment identifier of the target data segment does not exist in the content information, it is determined that the target data segment belongs to the problem data segment. That is, if some third parties add or modify some data in the content data of the target display content, but for these added or modified data, the third parties do not adaptively forge the addition of the corresponding first segment identification in the content information, then for these data segments for which the first segment identification does not exist, the consumer device may directly determine it as a problem data segment.
In another case, if the first segment identifier of the target data segment exists in the content information and the first segment identifier of the target data segment is the same as the second segment identifier of the target data segment, it is determined that the target data segment does not belong to the problem data segment. If the first segment identifier of the target data segment exists in the content information and the first segment identifier of the target data segment is different from the second segment identifier of the target data segment, determining that the target data segment belongs to the problem data segment.
For example, the first segment of the target data segment a included in the content information is identified as F1, the second segment of the target data segment a calculated by the consumer device is identified as F2, and then, if the F1 and the F2 are the same, it is determined that the target data segment a does not belong to the problem data segment if the F1 and the F2 are the same, and if the F1 and the F2 are different, it is determined that the target data segment a belongs to the problem data segment.
In step 305, the problem data segments in the content data are removed.
For the problem data segment, the part of the problem data segment is removed before content display is carried out, so that the problem data segment cannot be displayed.
And 306, displaying the target display content based on the content data after the problem data fragments are removed.
And analyzing and rendering and displaying the content data with the problem data fragments removed, so as to realize the display of the target display content.
In summary, in the technical solution provided in the embodiments of the present application, after content data is segmented in the parsing process of the target display content, whether the data segment belongs to the problem data segment is checked according to the segment identifier, and the problem data segment is removed, so that even if malicious tampering occurs in the parsing process, the malicious tampering can be successfully detected through checking the accuracy of the segment identifier, so as to achieve a better tamper-proof effect. In addition, through removing the problem data fragments and then displaying, normal display of target display contents can be ensured as much as possible, malicious added contents (such as advertisements or fraud information) are avoided, and browsing experience of users is improved.
In addition, the cost of hijacking prevention is low, complex encryption process is not required to be configured, who is hijacked is not required to be positioned, and the hijacking is not required to be avoided by manually switching transmission schemes. The normal display content can be restored only by checking and comparing whether the segment identification of each data segment is accurate or not by the client.
In the following, the technical scheme of the application is described by taking the generation and display process of the web page as an example.
As shown in fig. 5, in the process of generating the content information of the web page, the web page file of the web page is divided into a plurality of data segments (or referred to as page segments) by taking a web tag as a unit, a random string is spliced on each data segment to obtain spliced data, and a hash value of the spliced data is calculated as an id (identity) of the data segment (corresponding to the first segment identifier above). And then, packaging the content information of the webpage and then publishing the packaged content information to a server, wherein the server stores the content information of the webpage, and the content information comprises a webpage file of the webpage and ids of all data fragments in the webpage file. In addition, the page address of the webpage and the random character string can be correspondingly stored in a database.
Assuming that a single web page tag is used as granularity for segmentation, for a certain web page tag P1 in a web page file, splicing a random character string S on the web page tag P1 to obtain spliced data Q1, and calculating the hash value of the spliced data Q1 to be S1, wherein the id of the web page tag P1 is S1. The next web page tag of the web page tag P1 is P2, a random string S is spliced on the web page tag P2 to obtain spliced data Q2, and the hash value of the spliced data Q2 is calculated to be S2, so that the id of the web page tag P2 is S2.
The server sends the content information of the webpage to the client (such as a browser) for display, and in the transmission process of the content information or in the analysis process after the client receives the content information, a malicious third party may add some content (such as advertisement or fraud information) in the webpage file of the webpage. In this example, assume that a third party adds a web page tag C behind web page tag P1.
The client uses the same segmentation method to segment the web page file of the web page into a plurality of data segments (or called page segments). In addition, the client can acquire the random character string corresponding to the webpage from the database. For each data segment, concatenating the random string over the data segment to obtain concatenated data, and calculating a hash value of the concatenated data as an alignment id (corresponding to the second segment identifier above) of the data segment. And then comparing the comparison id of the data segment with the id contained in the content information of the webpage to determine whether the data segment is a problem data segment. And eliminating the problem data fragments, and analyzing and rendering the webpage file after eliminating the problem data fragments, so that the webpage is restored and displayed.
For example, for the web tag P1, the client concatenates the random string S on the web tag P1 to obtain the concatenated data Q1' (in the case that the web tag P1 is not tampered, the Q1' should be the same as Q1, but if the web tag P1 is tampered, the Q1' is different from Q1), and then calculates the Hash value of the concatenated data Q1' as S1' using the Hash algorithm. If the id of the web page tag P1 included in the content information is S1 and the comparison finds that S1 is the same as S1', then the web page tag P1 is determined to be legal content.
Further, the client obtains the next web page tag of the web page tag P1, since the third party is behind the web page tag P1If a web page tag C is added, the client acquires the web page tag C at the moment, splices a random character string S on the web page tag C to obtain spliced data D, and then calculates a Hash value of the spliced data D to be S by adopting a Hash algorithm 0 . The client finds that the id of which web page tag in the content information is S 0 . The client can determine the web page tag C as illegal content and reject it.
