Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 provides a data processing method for performing content auditing according to an embodiment of the present application, and includes the following steps S1 to S4:
s1, acquiring first characteristic information corresponding to first multimedia data played by a monitored object; wherein the first characteristic information is information for characterizing uniqueness of the first multimedia data.
Specifically, the first feature information may be non-modifiable unique information corresponding to the first multimedia data. Alternatively, the hash value may be calculated by an encryption means such as MD 5.
The multimedia data may be: one or more of video data, audio data, or image data.
The hash value functions as follows: the primary use of HASH values, i.e., HASH values, is for file verification or signing. It is because of this feature that it is often used to determine whether two files are identical.
For example, when two files exist, the hash values of the two files are compared, and if the two files are the same, the two files are completely consistent; and if not, it indicates that the two files are not identical.
Further, the first characteristic information may be obtained by performing hash value calculation on a full file of the first multimedia data; when the first multimedia data is video data or image data, the first feature information may also be obtained by performing hash value calculation on one or more captured pictures of the first multimedia data according to a preset image frame capture strategy (for example, capturing one frame every 10 frames, or capturing one frame every second, etc.); when the first multimedia data is audio data, the first feature information may also be obtained by performing a hash value calculation on one or more audio segments of the audio data obtained by intercepting the audio data at preset time intervals (for example, obtaining an audio segment with a duration of one second every 15 seconds, and the like).
S2, acquiring second characteristic information corresponding to the monitored object in a preset block chain; the second characteristic information is information for representing uniqueness of second multimedia data delivered to the monitored object.
Specifically, the second multimedia data is multimedia data delivered to the monitoring object in advance according to a preset plan, so that the monitoring object plays the second multimedia data. Optionally, the second multimedia data may include one or more second multimedia data, and the second multimedia data is stored in different blocks according to the distribution time when the second multimedia data is stored in the block chain; when a plurality of multimedia data are simultaneously distributed, hash values respectively corresponding to each multimedia data may be stored in the same tile.
The establishment of one optional block chain can adopt linux system deployment, the kernel is more than 2.7x, the dominant frequency is more than 2.0GHz, the single-node memory is 64G, the hard disk capacity is more than 200G, the property is distributed nodes, and the node specification is 2f +1 fault-tolerant deployment; the configuration of each block link point may adopt: each main participant corresponds to a cluster; and the project deployment can be completed by logging in a blockchain server in sequence, starting a deployment script, establishing three-way communication of an agent, a gateway and a consensus node, establishing communication between the node and a local rocksDB database (an embeddable and durable key-value storage database), backing up encrypted information such as public and private keys and testing an interface.
And S3, comparing the first characteristic information with the second characteristic information to obtain a consistency relation between the first multimedia data and the second multimedia data.
Specifically, on the basis of the example given in the foregoing step, the first feature information and the second feature information are both hash values as an example; since the hash value is a binary value with a specific length (e.g., 128 bits), the first characteristic information and the second characteristic information can be compared character by character to obtain a consistency relationship between the first characteristic information and the second characteristic information.
The consistency relation is used for representing whether the first characteristic information is consistent with the second characteristic information; for example, to facilitate computer identification; when the first feature information and the second feature information are consistent, the obtained consistency relationship may be information indicating that both are consistent, such as "0", and when both are not consistent, the obtained consistency relationship may be "1".
Further, when there is only one second feature information delivered to the monitored object, the consistency relationship may be whether the first feature information and the second feature information are completely consistent. When the second feature information includes a plurality of pieces, the first feature information may be compared with each piece of second feature information one by one to obtain a consistency relationship with each piece of second feature information, and optionally, when the first feature information is consistent with one piece of second feature information, it is determined that the first feature information satisfies the consistency relationship; and when the first characteristic information is inconsistent with any second characteristic information, judging that the first characteristic information and the second characteristic information do not meet the consistency relation.
And S4, determining an auditing result corresponding to the monitored object according to the consistency relation.
Specifically, the monitoring object is monitored to determine whether multimedia data played by the monitoring object is consistent with the multimedia data requested to be played.
The auditing result can be used for judging whether the playing behavior of the monitored object meets the preset requirement.
Therefore, determining the auditing result corresponding to the monitored object according to the consistency relationship may be: after the consistency relationship is obtained, whether the multimedia data played by the monitoring object is consistent with the preset playing is determined according to the consistency relationship, and then an auditing result corresponding to the monitoring object can be obtained.
By the method in the embodiment, the multimedia data played by the monitored object can be verified through the block chain, and the auditing result is obtained; compared with manual inspection, the efficiency can be effectively improved, and the time and the labor cost are saved; the multimedia data monitoring is carried out without adding extra monitoring equipment, the cost can be effectively reduced, the second multimedia information is stored in the block chain, the anti-counterfeiting, non-repudiation and traceability characteristics can be given to the historical records, and the follow-up maintenance and inspection work is guaranteed.
As shown in fig. 2, in some embodiments, the data processing method further includes steps P1 to P4 as follows:
and P1, acquiring all second multimedia data needing to be delivered to the monitored object.
And P2, determining second characteristic information corresponding to each second multimedia data.
Step P3, determining the block information of the block written with the second characteristic information; the block chain comprises a plurality of blocks.
And P4, establishing a corresponding relation between the block information and the monitored object.
Specifically, all the second multimedia data delivered to the monitored object can be obtained by uploading multimedia data to a device for implementing the method of the present application by an initiator having a delivery requirement; and the associated second multimedia data may be stored in a specific database or cache. And then, carrying out hash value calculation on the second multimedia data to obtain second characteristic information.
In addition, the initiator can also directly send the second feature information to the terminal, and then the second feature information obtained by calculation is uploaded to a device for implementing the method of the present application and stored in a cache.
In particular, the block information may be height information of the block, i.e. information characterizing the order in which the block is written into the block chain. And typically, in a blockchain, one block is generated for each transaction and then synchronized to other blockchain nodes after consensus is achieved. Therefore, each time the multimedia information is released (i.e. the multimedia information is sent to the playing terminal (including the monitoring object)), a corresponding block is generated.
Further, each block may store related information corresponding to the release behavior, including at least: identification information of the monitoring object (for example, ID of the monitoring object, address of the monitoring object, etc.) and characteristic information corresponding to the multimedia information.
After the identification information of the monitoring object is written in the block, the corresponding relation between the height information of the block and the identification information of the monitoring object can be established and written in a specific data table, so that the purpose of establishing the corresponding relation between the block information and the monitoring object is achieved.
By the method in the embodiment, the block can be conveniently positioned in the later stage, and the second characteristic information corresponding to the monitored object can be quickly inquired to improve the verification efficiency.
In some embodiments, as in the foregoing data processing method, the step S2 of obtaining the second feature information corresponding to the monitored object in the preset block chain includes the following steps S21 and S22:
and S21, inquiring all block information corresponding to the monitored object according to the corresponding relation.
Specifically, on the basis of the example given in the foregoing embodiment, when the corresponding relationship is the corresponding relationship between the height information of the block and the identification information of the monitoring object established in the specific data table; the method comprises the steps of acquiring first characteristic information corresponding to first multimedia data played by a monitored object and acquiring identification information of the monitored object; and further, the identification information of the monitored object can be inquired in the data table to obtain all block information in which the relevant information of the monitored object is stored, so that the corresponding block can be positioned in the block chain according to the block information.
And S22, calling and obtaining all second characteristic information in the corresponding block according to the block information.
Specifically, after the block information is obtained, the block storing the related information of the monitored object can be located and obtained; and then, second characteristic information of all multimedia data sent to the monitored object can be obtained from the block.
Furthermore, since the blocks are generated in sequence according to the transaction time, when a plurality of multimedia data are sent to the monitoring object through a plurality of operations, a plurality of blocks need to be obtained according to the block information positioning, and the second characteristic information is obtained from the plurality of blocks respectively.
In some embodiments, as in the foregoing data processing method, the step S1 of obtaining the first feature information corresponding to the first multimedia data played by the monitored object includes the following steps S11 and S12:
and S11, receiving encryption information for encrypting the third characteristic information through a private key and signature information for digitally signing the encryption information.
Specifically, the third characteristic information may be characteristic information that is directly obtained by the monitoring object and corresponds to the played multimedia data.
The receiving of the information sent by the monitored object end includes: encryption information encrypted by a private key and signature information digitally signed on the encryption information.
In general, the encryption information may be: and encrypting the third characteristic information through a private key to obtain the information.
Optionally, the method for performing digital signature may be: and signing the encrypted information by using a SHA1 signing method to obtain signed information. The received information may be information obtained by packaging signature information and encrypted information.
And S12, after the signature information is verified and passes the verification, decrypting the encrypted information through a public key corresponding to the private key to obtain first characteristic information.
Specifically, the signature information is verified, that is, the signature information is used for verifying whether the identity of the sender of the encrypted information is a specified object; further, the public key and the private key are a key pair obtained by an algorithm, so that the public key and the private key can be decrypted with each other.
After the signature information is verified, the description information is not tampered, and therefore the encrypted information is decrypted through the corresponding public key to obtain the first characteristic information. When the signature information is not verified, the sender is not the specified object, so that the hash value is checked without continuously decrypting.
Furthermore, the third verification information may be information obtained by encoding the hash value, and the encoded information may have good robustness, security and legibility in view of an EXtensible Markup Language (XML), which is a Markup Language and can conveniently implement common functions such as data exchange, system configuration, content management, and the like; the XML encoding mode may be selected to encode the hash value.
Therefore, in step S12, it is also necessary to decode the decrypted information by using the corresponding XML decoding method to obtain the first feature information.
In addition, because the size of each data packet is limited when data is sent, and in order to avoid ensuring the efficiency of data communication, the monitoring object end can inject encryption information and signature information into a protocol (i.e., protocol buffers, which is a method for language-independent, platform-independent and extensible serialized structured data, and can be used for communication protocols, data storage and the like) to obtain a data packet to be sent; a preset splitting strategy is adopted to perform sub-packaging and packing operations on data to be sent; and packaging the data packets into a plurality of data packets to be sent and then sending the data packets. The packet body of the protobuf protocol is small, light and more suitable for communication among services.
Correspondingly, in step S11, the received data packet needs to be processed (generally, including packetizing and depacketizing) to obtain the encryption information and the signature information.
One of the optional implementations may be: a terminal is implanted with a specific SDK (for obtaining the currently played content of a monitored object), and establishes MQTT (Message Queuing Telemetry Transport protocol), which is a Message protocol based on a publish/subscribe paradigm under ISO standard (ISO/IEC PRF 20922), long-link communication with a monitoring server (a server implementing the method of this embodiment), so that, in view of the fact that XML-encoded information can have good robustness, security and legibility, broadcast control data is encoded through XML, then private key signatures are sequentially performed after SHA1 signatures (for obtaining hash values) are performed, and the private key signatures are injected into protobuf codes to be converted into a binary format, and then binary components are packaged into data packets to be sent through packetizing and packaging operations, and the data packets are directly sent to the network monitoring server through MQTT long-link.
The monitoring server receives the data packet in real time, converts the data packet into a normalized character array through packet unpacking, decodes the normalized character array through protobuf, and decrypts the data packet through an encryption public key after the signature verification is successful; and then, carrying out secondary decoding on the decrypted information through XML to obtain final data to be verified (namely first characteristic information).
The third characteristic information is encrypted through a private key, so that data leakage can be effectively prevented; meanwhile, digital signature is carried out, so that illegal personnel such as hackers can be prevented from tampering information uploaded by the monitored object; and the data security can be guaranteed from multiple aspects. In some embodiments, as the foregoing data processing method, after obtaining the consistency relationship between the first multimedia data and the second multimedia data in step S3, the method further includes steps S5 and S6 as follows:
and S5, generating an alarm instruction when the consistency relationship represents that the first characteristic information is inconsistent with the second characteristic information.
And S6, sending the alarm instruction to the monitored object so that the monitored object stops playing the first multimedia data according to the alarm instruction.
That is to say, when the first characteristic information is inconsistent with the second characteristic information, the first multimedia data representing the playing of the monitoring object is not the multimedia data whose playing is controlled in advance.
Generating the corresponding alarm instruction may include: the instruction executes the content (e.g., stops playing) and issues the address (i.e., the address of the monitored object).
After the alarm instruction is sent to the monitoring object according to the issued address, the alarm instruction can be analyzed through the SDK arranged at the local end of the monitoring object to obtain instruction execution content, and the playing of the first multimedia data is stopped.
In addition, the alert instruction may further include: platform alarm instructions (e.g., push information or sound and light alarm); the method and the device are used for pushing alarm information to a related management end according to a platform alarm instruction, so that management end personnel know that the first multimedia data played by the monitored object violates the rule, and further can perform manual processing under the condition that the terminal cannot automatically process the data.
As shown in fig. 3, in some embodiments, after the alarm instruction is sent to the monitoring object, the data processing method further includes steps S7 to S9 as follows:
and S7, after a preset time period, acquiring third multimedia data played by the monitored object.
And S8, generating a shutdown instruction when the third multimedia data is inconsistent with the second multimedia data.
And S9, sending a shutdown instruction to the monitored object so as to forcibly shut down the monitored object.
The length of the preset time period can be adaptively adjusted according to factors such as the execution time required for switching videos or stopping playing videos in practical application.
The third multimedia data is multimedia data which is generated by issuing the generated alarm instruction to the monitoring object and is played by the monitoring object after a preset time period; therefore, the third multimedia data may or may not be identical to the first multimedia data.
