Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a data verification method, apparatus, device, and storage medium. Background Technology

[0002] With the development of the internet, real-time multimedia applications have gradually become an indispensable part of the internet. Multimedia technology plays a crucial role in many application areas.

[0003] Currently, existing multimedia data verification technologies are mainly applied to the detection of video content tampering, lacking other aspects of content verification. One method used in existing technologies is to extract features from keyframes in the video for verification. This method requires accurate identification and extraction of keyframes, which is complex to implement and prone to missed detections and errors. Another data verification method often uses the same link for multimedia data transmission and verification. When there is a large amount of data in the channel, it can affect network transmission performance, easily leading to data reuse, transmission chaos, and verification errors. There is also a risk of network interruption due to equipment failure. Summary of the Invention

[0004] This invention provides a data verification method, apparatus, device, and storage medium that achieves real-time verification of audio and video data through bypass deployment without frame extraction, ensuring the real-time performance and accuracy of audio and video data verification, as well as the smoothness and stability of audio and video data transmission.

[0018] This invention discloses a data verification method, apparatus, device, and storage medium.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0031] It should be noted that the terms "first," "second," and "target," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0032] Example 1

[0033] Figure 1 This is a flowchart of a data verification method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of real-time verification of audio and video encoded data. The method can be executed by a data verification device, which can be implemented in hardware and / or software.

[0034] like Figure 1 As shown, the method includes:

[0035] S101. Obtain the target audio and video data packets corresponding to the target audio and video encoding in the given original transmission channel.

[0036] In this embodiment, the target audio / video encoding can be understood as the audio and video encoded data to be transmitted or being transmitted. The given original transmission channel can be understood as the data transmission channel used to transmit the target audio / video encoding. The target audio / video data packet can be understood as a data packet encapsulated based on the target audio / video encoding and its corresponding basic parameter data.

[0037] Specifically, after the sending device responds to the corresponding audio and video encoding acquisition request and sends the target audio and video data packet corresponding to the target audio and video encoding according to the given original transmission channel, a data verification device of this embodiment is executed to obtain the target audio and video data packet corresponding to the target audio and video encoding from the given original transmission channel.

[0038] It is understood that the target audio and video data packets are encapsulated and transmitted according to a preset communication protocol, and this embodiment does not limit the type of communication protocol.

[0039] S102. Allocate a verification channel for the target audio and video data packet, and generate the current fingerprint data packet encoded by the target audio and video data packet in the verification channel.

[0040] In this embodiment, the verification channel can be understood as a channel used for feature extraction and verification based on the target audio / video data packet; it is a physical channel separately allocated for performing data feature extraction and verification. The current fingerprint data packet can be understood as a data packet generated based on the fingerprint features after fingerprint feature extraction from the target audio / video data packet in the verification channel.

[0041] Specifically, a corresponding verification channel is allocated to the target audio and video data packets. This allows the target audio and video data packets to be transmitted from the given original transmission channel while feature extraction and real-time verification are performed within the allocated verification channel. A fingerprint feature extraction module is deployed in the verification channel. When the fingerprint feature extraction module receives the target audio and video data packets in the verification channel, it extracts fingerprint features from the target audio and video data packets to obtain the fingerprint feature information corresponding to the target audio and video encoding. This fingerprint feature information is then encapsulated to obtain the current fingerprint data packet.

[0042] It is understandable that the fingerprint feature information in the current fingerprint data packet is standard fingerprint feature information, which can be used to verify the data.

[0043] S103. During the data packet transmission process through the original transmission channel, the target audio and video data packet is verified in the verification channel based on the current fingerprint data packet to determine the verification result of the target audio and video encoding.

[0044] In this embodiment, the verification result can be understood as the result of whether the target audio and video codec has been tampered with during the transmission process, including two results: the target audio and video codec has been tampered with and the target audio and video codec has not been tampered with.

[0045] Specifically, a fingerprint feature verification module is deployed in the verification channel. During the transmission of data packets through the given original transmission channel, corresponding fingerprint feature information is generated in the verification channel based on the target audio and video data packets transmitted through the original transmission channel. The fingerprint feature verification module compares the generated new fingerprint feature information with the fingerprint feature information in the current fingerprint data packet, and determines whether the target audio and video encoding has been tampered with based on the comparison result.

[0046] In this embodiment, the target audio and video data packet corresponding to the target audio and video encoding in a given original transmission channel is obtained; a verification channel is allocated to the target audio and video data packet, and a current fingerprint data packet of the target audio and video encoding is generated in the verification channel based on the target audio and video data packet; during the data packet transmission through the original transmission channel, the target audio and video data packet is verified in the verification channel based on the current fingerprint data packet to determine the verification result of the target audio and video encoding. The above technical solution uses two channels to separately implement the transmission and verification of audio and video data, enabling real-time verification of audio and video data while the audio and video data is being transmitted. Therefore, this solution can achieve real-time verification of audio and video data through a bypass deployment without frame extraction, ensuring the real-time performance and accuracy of audio and video data verification, as well as the smoothness and stability of audio and video data transmission.

[0047] As a first optional embodiment of the embodiments, based on the above embodiments, this first optional embodiment further optimizes and adds: when the verification result indicates that the target audio and video encoding has been tampered with, an alarm message is generated and sent to the corresponding receiving device.

[0048] In this embodiment, the alarm information can be understood as an alarm automatically issued when the target audio and video codec is detected to have been tampered with, which includes the verification result, the tampering status of the target audio and video codec, and the location where the target audio and video codec has been tampered with.

[0049] Specifically, when the verification result indicates that the target audio / video encoding has been tampered with, a corresponding alarm message is automatically generated at that location and sent to the receiving device corresponding to the target audio / video data packet. This allows the receiving device to locate the location of the tampering event based on the alarm message reported in real time, and to execute corresponding countermeasures locally according to the pre-set anomaly response plan to correct the data tampering behavior during transmission.

[0050] Example 2

[0051] Figure 2 This is a flowchart of a data verification method provided in Embodiment 2 of the present invention. This embodiment is a further optimization of any of the above embodiments and can be applied to the situation of real-time verification of audio and video encoded data. The method can be executed by a data verification device, which can be implemented in hardware and / or software.

[0052] like Figure 2 As shown, the method includes:

[0053] S201. Obtain the target audio and video data packets corresponding to the target audio and video encoding in the given original transmission channel.

[0054] S202. Allocate the first interactive network port and the second interactive network port to the target audio and video data packets to form a verification channel.

[0055] In this embodiment, both the first interactive network port and the second interactive network port can be understood as network ports used for data interaction between the original transmission channel and the verification channel. The first interactive network port is the network port that receives data from the original transmission channel into the verification channel. The second interactive network port is the network port that receives data from the verification channel back to the original transmission channel.

[0056] It is understandable that during data transmission, multiple network ports can exist to facilitate data interaction between the two channels. The network port through which data flows from the original transmission channel to the verification channel is collectively referred to as the first interaction network port, and the network port through which data flows from the verification channel to the original transmission channel is collectively referred to as the second interaction network port. It is not that there are only two network ports.

[0057] Specifically, a first interactive network port and a second interactive network port are allocated to the target audio and video data packets to form a verification channel for feature extraction and verification of the target audio and video.

[0058] S203. Input the current original file data packet into the verification channel, and extract features from the current original file data packet to generate the current fingerprint data packet of the target audio and video encoding.

[0059] In this embodiment, the current original file data packet is transmitted to the verification channel through a pre-allocated network port. In the verification channel, the current original file data is subjected to feature extraction to obtain the fingerprint feature information of the target audio and video data packet, and the target audio and video encoded current fingerprint data packet is generated based on the fingerprint feature information.

[0060] Optionally, inputting the current original file data packet to the verification channel includes: mirroring the target audio and video data packet from the original transmission channel to the verification channel through the first interactive network port.

[0061] Specifically, the target audio and video data packets are mirrored from the original transmission channel to the verification channel via the first interactive network port. At this time, the target audio and video data packets are still stored and transmitted in the original transmission channel, and the mirrored target audio and video data packets also exist in the verification channel.

[0062] By using mirror transmission, the target audio and video data packets transmitted in the original transmission channel remain unchanged, reducing the possibility of mutations in the target audio and video data packets during transmission and verification. This also ensures the stability and smoothness of data transmission, reducing the occurrence of audio and video stuttering.

[0063] Optionally, feature extraction is performed on the current original file data packet to generate the current fingerprint data packet encoded with the target audio and video, including:

[0064] S2031. Extract the five-tuple information, data packet sequence number, data packet timestamp, and data packet length from the target audio and video data packet.

[0065] In this embodiment, the five-tuple information, sequence number, and timestamp of the target audio / video data packet are extracted from the target audio / video data packet header. Before transmitting the target audio / video data packet, there may be historical audio / video data packets of the target audio / video encoding that have already been transmitted. The data length of the target audio / video encoding transmitted based on the historical audio / video data packets is calculated.

[0066] The data packet consists of a header and a payload. The header includes the protocol version number, payload type, packet sequence number, packet timestamp, and synchronization source identifier. The 5-tuple information includes the source IP address, source port, destination IP address, destination port, and protocol version number. The packet sequence number identifies the sequence number of the target audio / video data packet sent by the sending device, and increments by 1 for each data packet sent. The receiving device can use the sequence number to detect the loss of target audio / video data packets, reorder the packets, and recover the data. The packet timestamp reflects the sampling time of the first octet of the target audio / video data packet. The receiving device can use the timestamp to calculate latency and jitter, and perform synchronization control.

[0067] S2032. Based on the quintuple information, data packet sequence number, data packet timestamp, and data packet length, determine the current fingerprint feature information corresponding to the target audio / video data packet.

[0068] In this embodiment, the current fingerprint feature information can be understood as the fingerprint feature information determined after feature extraction of the target audio and video data packet, which is the summary information of the target audio and video data packet.

[0069] Specifically, in terms of data storage, different multimedia content corresponds to different lengths and binary content. Since the transmitted target audio and video encoding may contain a large amount of information, the digest information of the transmitted target audio and video encoding is calculated using a preset digest algorithm based on the five-tuple information in the packet header, the packet sequence number, the packet timestamp, and the length of the target audio and video encoding packets transmitted before the target audio and video packet. This digest information is used as a unique fingerprint for each transmission and serves as a correct reference for the current transmitted content.

[0070] The preset digest algorithm can be Cyclic Redundancy Check (CRC), MD5 message digest algorithm, Secure Hash Algorithm (SHA1), SHA256 and related variant algorithms. This embodiment does not limit this.

[0071] It is understandable that in certain situations, encrypted computation can be introduced during the calculation of the digest value of the transmitted content. The computation result can be protected by pre-deployed certificates / signatures or real-time negotiated keys. The specific encryption algorithm can be selected according to the actual computing power and deployment scenario. This embodiment does not limit this.

[0072] S2033. Encapsulate the current fingerprint feature information into a current fingerprint data packet.

[0073] In this embodiment, since the current fingerprint feature information cannot be directly transmitted within the channel, the current fingerprint feature information is encapsulated into a current fingerprint data packet to facilitate information transmission.

[0074] S204. Input the current fingerprint data packet to the original transmission channel via the second interactive network port of the verification channel, and transmit the target audio and video data packet and the current fingerprint data packet through the original transmission channel.

[0075] In this embodiment, after extracting the fingerprint features of the current data packet and generating the current fingerprint data packet, the current fingerprint data packet is transmitted from the verification channel to the original transmission channel through the second interactive network port. Within the original transmission channel, the target audio / video data packet and the current fingerprint data packet are transmitted together. The transmission of the current fingerprint data packet from the verification channel to the original transmission channel through the second interactive network port can be either mirror transmission or direct transmission; this embodiment does not impose any limitations on this.

[0076] S205. During the transmission process through the original transmission channel, generate fingerprint feature information to be verified based on the target audio and video data packets in the verification channel.

[0077] In this embodiment, during the transmission of the target audio / video data packet and the current fingerprint data packet through the original transmission channel, when a verification requirement arises, the target audio / video data packet and the current fingerprint data packet are mirrored from the original transmission channel to the verification channel via the first interactive network port. Within the verification channel, corresponding fingerprint feature information to be verified is generated based on the target audio / video data packet. The steps for generating the fingerprint information to be verified are the same as those for generating the current fingerprint feature information, and will not be described again in this embodiment.

[0078] S206. Compare the current fingerprint feature information in the current fingerprint data packet with the fingerprint feature information to be verified to determine the verification result of the target audio and video encoding.

[0079] In this embodiment, if the target audio and video encoding to be transmitted changes, the corresponding fingerprint feature information related to the transmitted content will also change. Therefore, the current fingerprint feature information in the current fingerprint data packet is compared with the fingerprint feature information to be verified to determine the comparison result. Based on the comparison result, it is determined whether the target audio and video encoding has been tampered with, and the verification result is obtained.

[0080] Optionally, the current fingerprint feature information in the current fingerprint data packet is compared with the fingerprint feature information to be verified to determine the verification result of the target audio / video encoding, including:

[0081] S2061. Compare the current fingerprint feature information in the current fingerprint data packet with the fingerprint feature information to be verified, and determine whether the current fingerprint feature information and the fingerprint feature information to be verified are consistent.

[0082] The current fingerprint feature information in the current fingerprint data packet is compared with the fingerprint feature information to be verified. The comparison result is determined to determine whether the current fingerprint feature information and the fingerprint feature information to be verified are consistent.

[0083] S2062. If so, confirm that the verification result indicates that the target audio / video encoding has not been tampered with.

[0084] In this embodiment, if the comparison result shows that the current fingerprint feature information is consistent with the fingerprint feature information to be verified, it means that the target audio and video encoding in the currently received target audio and video data packet has not been tampered with during transmission.

[0085] S2063. If not, the verification result is determined to be an event of tampering with the target audio / video encoding.

[0086] In this embodiment, if the comparison result shows that the current fingerprint feature information is inconsistent with the fingerprint feature information to be verified, it indicates that the target audio and video encoding in the currently received target audio and video data packet has been tampered with during transmission.

[0087] In this embodiment, the target audio and video data packets corresponding to the target audio and video encoding in a given original transmission channel are obtained; a first interactive network port and a second interactive network port are allocated to the target audio and video data packets to form a verification channel; the current original file data packet is input to the verification channel, and feature extraction is performed on the current original file data packet to generate the current fingerprint data packet of the target audio and video encoding; the current fingerprint data packet is input to the original transmission channel via the second interactive network port of the verification channel, and the target audio and video data packet and the current fingerprint data packet are transmitted through the original transmission channel; during the transmission through the original transmission channel, fingerprint feature information to be verified is generated in the verification channel based on the target audio and video data packet; the current fingerprint feature information in the current fingerprint data packet is compared with the fingerprint feature information to be verified to determine the verification result of the target audio and video encoding. In the above technical solution, data transmission is performed in the original transmission channel, and data packet verification is performed in the verification channel. Mirror transmission of data between the two channels is achieved according to the preset network port, which enables real-time verification of the target audio and video encoding and ensures the consistency of data packet transmission. Therefore, the above scheme can achieve real-time verification of audio and video data through bypass deployment without frame extraction, ensuring the real-time performance and accuracy of audio and video data verification, as well as the smoothness and stability of audio and video data transmission.

[0088] To more clearly explain a data verification method according to an embodiment of the present invention, Figure 3 This is an example illustration of the transmission process involved in a data verification method provided in Embodiment 2 of the present invention, as shown in the diagram. Figure 3 As shown, the receiving end device receives the target audio / video data packet sent by the sending end device, allocates a verification channel for the target audio / video data packet, mirrors the target audio / video data packet from the original transmission channel to the verification channel, extracts features from the target audio / video data packet from the verification channel, and transmits the generated current fingerprint data packet to the original transmission channel along with the target audio / video data packet. When a verification requirement arises, the target audio / video data packet and the current fingerprint data packet are mirrored to the verification channel for verification and the verification result is determined. If the verification result indicates that no tampering event has occurred, no action is taken; if a tampering event occurs along the transmission route, the real-time verification result is determined to indicate that a tampering event has occurred, and an alarm message is reported to the receiving end device.

[0089] Figure 4 This is an example illustration of feature extraction involved in a data verification method provided in Embodiment 2 of the present invention. Figure 4As shown, the target audio and video data packet flows into the original transmission channel. While the target audio and video data packet is being transmitted in the original transmission channel (from port 1 to port 5), the target audio and video data packet is mirrored from the original transmission channel to the verification channel via the first interactive port (mirrored from port 1 to the first interactive port). The fingerprint feature extraction module extracts features to generate the current fingerprint data packet. The current fingerprint data packet is transmitted from the second interactive port to the original transmission channel (from the second interactive port to port 2). The current fingerprint data packet is then transmitted in the original transmission channel (from port 2 to port 5). Finally, the target audio and video data packet and the current fingerprint data packet are transmitted together into the network via port 5.

[0090] Because audio and video data can be transmitted bidirectionally. Figure 5 This is another example illustration of feature extraction involved in a data verification method provided in Embodiment 2 of the present invention. The specific extraction method is the same as... Figure 4 Similarly.

[0091] Figure 6 This is an example illustration of data verification involved in a data verification method provided in Embodiment 2 of the present invention, as shown in the figure. Figure 6 As shown, the target audio / video data packet and the current fingerprint data packet are transmitted in the original transmission channel. Simultaneously, while the target audio / video data packet is being transmitted in the original transmission channel (from port 1 to port 5), the target audio / video data packet and the current fingerprint data packet are mirrored from the original transmission channel to the verification channel via the first interactive port (mirrored from port 1 to the first interactive port). Feature extraction is performed on the target audio / video data packet to generate fingerprint feature information to be verified. The fingerprint feature verification module compares the current fingerprint feature information in the current fingerprint data packet with the fingerprint data information to be verified to determine the verification result of the target audio / video encoding. If the verification result indicates a tampering event, an alarm message is reported to the receiving device. The target audio / video data packet and the current fingerprint data packet continue to be transmitted together into the network via port 5.

[0092] Because audio and video data can be transmitted bidirectionally. Figure 7 This is another example illustration of data verification involved in a data verification method provided in Embodiment 2 of the present invention. The specific verification method is the same as... Figure 6 Similarly.
