In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0046] The video association method provided in the embodiment of the present application can determine the target data unit that meets the predefined unit type from the video to be released uploaded by the client, and extract the device identification from the target data unit to perform video association, without the need to receive other user information in addition. Related application scenarios may include: user portrait construction, video association recommendation, application data analysis, etc. The several application scenarios listed above are only exemplary and explanatory. In actual applications, the video association method can also be used in video association in other scenarios, and the embodiment of the present application does not limit this. The video association method, device, equipment, storage medium and program product provided in the embodiment of the present application are intended to solve the problem that the related technology needs to connect the identity system between different video applications or transmit user-related information separately, which affects the original data transmission process, has high complexity and low processing efficiency.

[0047] In the video association method provided in the embodiment of the present application, the executor of each step can be a computer device, which refers to any electronic device with data calculation, processing and storage capabilities, such as PC (Personal Computer), tablet computer and other terminal devices, and can also be servers and other devices, which are not limited in the embodiment of the present application.

[0048] Figure 1 A flowchart of a video association method provided in an embodiment of the present application. The video association method is applied to the server, such as Figure 1 As shown, the following steps are included:

[0049] Step S101: obtaining a video to be published uploaded by a client, and determining a target data unit that meets a predefined unit type from a plurality of data units into which the video to be published has been divided.

[0050] Among them, the video to be released can be obtained by inserting a pre-built target data unit that conforms to a predefined unit type into the original video by the client. The original video can be produced by different video applications according to their own established production processes, and the original video is composed of multiple data units with specific functions and structures. For example, for the original video in MP4 format, the corresponding data unit is a box unit, and for the original video in MOV format, the corresponding data unit is an atom unit. Of course, there can also be original videos in other video file formats, which are not limited in this application. Taking the original video in MP4 format as an example, it can include multiple box units of different unit types. For example, a box unit of moov type can store the overall information of media data, such as track information, time information, etc., and a box unit of trak type can store media data and its metadata. Different from the data unit of the original unit type in the original video, the target data unit is a predefined unit type, which is used to store encrypted content data containing a reference check value and a device identifier of the client. As a result, the multiple data units into which the video to be released has been divided contain both the original data unit of the original unit type and the target data unit of the predefined unit type. In one embodiment, the video file format of the received video to be published is a fixed format, and the preset field value corresponding to the predefined unit type can be directly compared with the field value of the unit type field corresponding to multiple data units to filter out the target data unit whose field value is the same as the preset field value. For example, for the video to be published in MP4 format, the unit type field box type of its data unit is 4 bytes in size, which is different from the original moov, trak and other field values. The preset field value can be customized to be xxxx. If the data unit with the field value of xxxx is determined through traversal, then the data unit can be regarded as the target data unit. In one embodiment, the video file format of the received video to be published can be different, and the customization methods and byte sizes of different video file formats and the corresponding unit type fields may be different. Therefore, the field values ​​of the predefined unit type settings corresponding to different video file formats may be different. Therefore, the target field value of the associated unit type field can be determined by querying according to the video file format, and then the multiple data units currently divided by the video to be published are traversed based on the target field value to filter out the target data unit whose field value of the unit type field is the target field value.

[0051] Step S102: extract the encrypted content data from the target data unit, decrypt the encrypted content data, and obtain a reference check value and a device identifier of the client.

[0052] Among them, the encrypted content data can be obtained by the client encrypting the reference check value and the device identification. The encryption process can be a symmetric encryption algorithm or an asymmetric encryption algorithm, for example, AES (Advanced Encryption Standard) algorithm, DSA (Digital Signature Algorithm), etc., which is not limited in this application. The encryption process can be used to prevent data theft. Accordingly, the server needs to deploy a decryption process that matches the encryption process performed by the client. The reference check value can be obtained by the client performing hash mapping processing on multiple data units that have been divided into the original video, which is used to detect whether the video to be released has been illegally tampered with or abnormally missing during the transmission process. The device identification can be a unique identifier of the terminal device to which the client belongs, specifically a 128-bit digital sequence. The device identification is generated when the device is initialized and can be used to distinguish it from other terminal devices.

[0053] Step S103: Perform hash mapping processing on other data units in the multiple data units excluding the target data unit to obtain a current check value, and compare the current check value with the reference check value.

[0054] Among them, the hash mapping process can be to use a specific hash function to calculate the hash value, for example, MD5 (Message-Digest Algorithm 5), SHA-1 (Secure Hash Algorithm-1), SHA-256 (Secure Hash Algorithm-256), etc. The specific calculation process needs to be consistent with the hash mapping process performed by the client on the multiple data units into which the original video has been divided. In one embodiment, the client can group the multiple data units into which the original video has been divided to calculate the hash values ​​and accumulate them to obtain a reference check value. Referring to the hash mapping process performed by the client, the server can group the other data units excluding the target data unit in the multiple data units according to a preset number threshold, and perform hash calculation on the data units in each group to obtain the corresponding hash value, and finally accumulate the corresponding hash values ​​of each group to obtain the total hash value, which can be used as the current check value. In one embodiment, the client can calculate the hash values ​​of the multiple data units that the original video has been divided into one by one and accumulate them to obtain a reference check value. Referring to the hash mapping process performed by the client, the server can calculate the corresponding hash values ​​of the other data units excluding the target data unit in the multiple data units, and accumulate the hash values ​​corresponding to each data unit to obtain a total hash value, which can be used as the current check value. By comparing the current check value with the reference check value, it can be effectively determined whether the other data units excluding the target data unit in the video to be released are consistent with the content of the multiple data units that the original video has been divided into, and then determine whether the video data has been illegally tampered with or abnormally missing.

[0055] Step S104: when the current check value is consistent with the reference check value, a first association relationship is established between the video to be released and the associated video corresponding to the device identifier.

[0056] Among them, if the current check value is inconsistent with the reference check value, it can be regarded that the video content of the video to be released may have been illegally tampered with or abnormally missing, and the video abnormality information needs to be fed back to the client. If the current check value is consistent with the reference check value, it can be regarded that the video content of the video to be released is consistent with the original video, and the device identifier is valid. A first association relationship between the video to be released and the associated video corresponding to the device identifier can be established. Specifically, the basic information of the video to be released, the device identifier, and multiple basic information of the associated videos corresponding to the device identifier can be associated and stored through lists, mapping tables, etc. The basic information may include video identifier, video size, video file format, creation time, video content description, etc., which is not limited in this application.

[0057] In the above, by obtaining the video to be released uploaded by the client, a target data unit that meets the predefined unit type is determined from the multiple data units into which the video to be released has been divided; the encrypted content data is extracted from the target data unit, and the encrypted content data is decrypted to obtain a reference verification value and a device identification of the client; other data units excluding the target data unit in the multiple data units are hash mapped to obtain a current verification value, and the current verification value is compared with the reference verification value; when the current verification value is consistent with the reference verification value, a first association relationship between the video to be released and the associated video corresponding to the device identification is established. In the above scheme, by determining the target data unit that meets the predefined unit type from the multiple data units that the video to be released has been divided into, the target data unit containing the device identification that the client additionally constructs can be effectively identified. By decrypting the encrypted content data, the reference check value and the client's device identification can be obtained to ensure the security and reliability of the data source. By comparing the current check value with the reference check value, it is possible to effectively check whether the video data has problems such as illegal tampering or abnormal missing, ensure the integrity and authenticity of the video to be released that needs to be associated, and when the current check value is consistent with the reference check value, construct a first association relationship between the video to be released and the associated video corresponding to the device identification. Video association can be completed by only receiving the video to be released uploaded by the client, and the videos produced on the same device on multiple video applications can be associated without receiving other user information separately. The data transmission process of the original video application is maintained, the association complexity is reduced, and the processing efficiency is improved.

[0058] Figure 2 A flowchart of a video association method including a process of determining a target data unit that conforms to a predefined unit type is provided in an embodiment of the present application. Figure 2 As shown, the following steps are included:

[0059] Step S201: Obtain the video to be published uploaded by the client.

[0060] Step S202: querying according to the video file format of the video to be released to determine the target field value of the associated unit type field.

[0061] The target field value is used to characterize the predefined unit type. In order to meet the video file format requirements of different application scenarios, the video file formats of different videos to be published uploaded by the same client may be different, and the field values ​​of the unit type fields set for the corresponding predefined unit types may be different. Therefore, it is necessary to query the relevant lists or mapping tables according to the video file format of each video to be published, so as to determine the target field value of the associated unit type field. For example, for a video to be published in MP4 format, the corresponding unit type field is box-type, and the corresponding field value can be xxxx.1 For a video to be released in MOV format, the corresponding unit type field is atom-type, and the corresponding field value can be xxxx 2 Specifically, the developer can set the field value of the corresponding predefined unit type according to different video file formats, and this application does not limit this.

[0062] Step S203: Filter out target data units whose field values ​​satisfy the unit type field as target field values ​​from the multiple data units currently divided into the to-be-published video.

[0063] Among them, if the field value of the unit type field of a data unit among the multiple data units currently divided into which the video to be released is consistent with the target field value, the data unit can be regarded as a target data unit autonomously constructed by the client, and the target data unit stores encrypted content data including a reference verification value and the client's device identification.

[0064] Step S204: extract the encrypted content data from the target data unit, decrypt the encrypted content data, and obtain a reference check value and a device identifier of the client.

[0065] Step S205: Perform hash mapping processing on other data units in the multiple data units excluding the target data unit to obtain a current check value, and compare the current check value with the reference check value.

[0066] Step S206: When the current check value is consistent with the reference check value, a first association relationship is established between the video to be released and the associated video corresponding to the device identifier.

[0067] As described above, by querying according to the video file format of the video to be released to determine the target field value of the associated unit type field, the field value of the predefined unit type corresponding to different video file formats can be effectively matched and determined, and the target data unit whose field value satisfies the unit type field as the target field value is screened out, the client's device identifier can be accurately extracted from the videos to be released in different video file formats, and video association can be effectively adapted to different video file formats.

[0068] Figure 3 A flowchart of a video association method including a process of performing hash mapping processing to obtain a current check value is provided in an embodiment of the present application. Figure 3 As shown, the following steps are included:

[0069] Step S301: Obtain a video to be published uploaded by a client, and determine a target data unit that meets a predefined unit type from a plurality of data units into which the video to be published has been divided.

[0070] Step S302: extract the encrypted content data from the target data unit, decrypt the encrypted content data, and obtain a reference check value and a device identifier of the client.

[0071] Step S303: respectively calculate the hash values ​​of other data units excluding the target data unit in the multiple data units, and accumulate the multiple hash values ​​corresponding to the other data units to obtain the current check value.

[0072] Among them, if the client calculates the hash values ​​of the multiple data units into which the original video has been divided one by one and accumulates them to obtain a reference verification value, referring to the hash mapping processing process performed by the client, in this embodiment, the same hash algorithm as the client can be used to calculate the hash values ​​of other data units in the multiple data units excluding the target data unit. The hash algorithm can be MD5, SHA-1, SHA-256 and other methods, which are not limited in this application, and the multiple hash values ​​corresponding to the other data units are accumulated to obtain the current verification value, which can be used to compare with the reference verification value to check whether the video to be released has any illegal tampering or abnormal missing during the data transmission process.

[0073] Step S304: compare the current check value with the reference check value, and when the current check value is consistent with the reference check value, establish a first association relationship between the video to be released and the associated video corresponding to the device identifier.

[0074] As mentioned above, by respectively calculating the hash values ​​of other data units excluding the target data unit in multiple data units, and accumulating multiple hash values ​​corresponding to other data units to obtain the current verification value, the current verification value that is compatible with the process of the client generating the reference verification value can be effectively determined, which is used for subsequent comparison to determine whether the video to be released has any abnormal video content problems.

[0075] Figure 4 A flowchart of a video association method including a process of determining a second association relationship is provided in an embodiment of the present application. Figure 4 As shown, the following steps are included:

[0076] Step S401: Obtain a video to be published uploaded by a client, and determine a target data unit that meets a predefined unit type from a plurality of data units into which the video to be published has been divided.

[0077] Step S402: extract the encrypted content data from the target data unit, decrypt the encrypted content data, and obtain a reference check value and a device identifier of the client.

[0078] Step S403: Perform hash mapping processing on other data units in the multiple data units excluding the target data unit to obtain a current check value, and compare the current check value with the reference check value.

[0079] Step S404: when the current check value is consistent with the reference check value, a first association relationship is established between the video to be released and the associated video corresponding to the device identifier.

[0080] Step S405: query the set database according to the device identification to obtain multiple currently associated videos.

[0081] Among them, after steps S401-S404 complete the construction of the first association relationship between one or more videos to be published uploaded by the client and the associated videos corresponding to the device identifier, the set database can be queried according to the device identifier to determine the latest associated multiple videos for classification association of subsequent videos.

[0082] Step S406: Perform content recognition on each video to obtain key content information, and determine at least one target video corresponding to the set classification label from multiple videos according to the key content information.

[0083] Among them, content recognition for each video can be performed by using a set multimodal large model to process the video to obtain key content information, or it can be performed by identifying and extracting semantic information from the audio content of the video to obtain key content information. The key content information may include one or more of character description information, scene description information, high-frequency vocabulary information, etc., which are not limited in this application. The classification label can be an identifier for classifying videos set in advance by the developer according to the actual application scenario, for example, science and technology, teaching, entertainment, etc. By matching the key content information of each video with the classification label for semantic similarity, at least one target video that meets the preset similarity corresponding to each classification label can be determined, so as to classify multiple videos associated with the device identifier into different preset categories.

[0084] Step S407: construct a second association relationship between the classification label and the corresponding at least one target video.

[0085] Among them, a second association relationship between a classification label and at least one corresponding target video is constructed. Specifically, the basic information of at least one target video and the classification label can be associated and stored in a list, a mapping table, etc. The basic information may include video ID, video size, video file format, creation time, video content description, etc., which is not limited in this application.

[0086] As described above, by constructing a second association relationship between a classification tag and at least one corresponding target video, multiple videos associated with the device identifier can be further classified to establish content connections between the videos.

[0087] Figure 5Flow chart of another video association method provided in an embodiment of the present application. The video association method is applied to a client, such as Figure 5 As shown, the following steps are included:

[0088] Step S501: obtain the original video and the device identification, and perform hash mapping processing on the multiple data units into which the original video has been divided to obtain a reference check value.

[0089] Among them, the original video can be created by the user according to the content materials and editing functions provided by different video applications, and produced by different video applications according to their own established production processes. The original video is composed of multiple data units with specific functions and structures. For example, for the original video in MP4 format, the corresponding data unit is a box unit, and for the original video in MOV format, the corresponding data unit is an atom unit. Of course, there can also be original videos in other video file formats, which are not limited in this application. The device identifier can be a unique identifier of the terminal device to which the client belongs, and can specifically be a 128-bit digital sequence. The device identifier is generated when the device is initialized and can be used to distinguish it from other terminal devices. The hash mapping process can be a hash value calculation using a specific hash function, such as MD5, SHA-1, SHA-256 and other methods. In one embodiment, the client can group the multiple data units into which the original video has been divided to calculate the hash value and accumulate it to obtain a reference check value. In one embodiment, the client can calculate the hash value of the multiple data units into which the original video has been divided one by one and accumulate it to obtain a reference check value. The reference check value can be provided to the server to determine whether the video data has been illegally tampered with or abnormally missing during the data transmission process, so as to ensure the security and effectiveness of the video content and device identification.

[0090] Step S502: encrypt the device identification and the reference check value to obtain encrypted content data.

[0091] The encryption process may be performed by using a symmetric encryption algorithm or an asymmetric encryption algorithm, such as AES, DSA and other algorithms, which are not limited in this application.

[0092] Step S503: construct a target data unit that conforms to the predefined unit type, and fill the encrypted content data into the target data unit.

[0093] Among them, taking the original video in MP4 format as an example, it can include multiple box units of different unit types. For example, the moov type box unit can store the overall information of the media data, such as track information, time information, etc., and the trak type box unit can store the stored media data and its metadata. Different from the data unit of the original unit type in the original video, a target data unit of a predefined unit type can be constructed to store encrypted content data, which can carry the device identification and reference check value without affecting the content playback of the original video.

[0094] Step S504: insert the target data unit into the preset unit position of the original video to obtain the video to be published, and upload the video to be published to the server, so that the server can build a first association relationship between the video to be published and the associated video corresponding to the device identifier.

[0095] Taking the original video in MP4 format as an example, the preset unit position can be the end position of the moov type box unit, so that the insertion of the target data unit does not affect the content playback of the original video. Uploading the video to be published to the server can enable the server to build a first association relationship between the video to be published and the associated video corresponding to the device identifier, thereby realizing video association of the same device.

[0096] In the above, by obtaining the original video and the device identification, the multiple data units into which the original video has been divided are hash mapped to obtain a reference check value; the device identification and the reference check value are encrypted to obtain encrypted content data; a target data unit that conforms to a predefined unit type is constructed, and the encrypted content data is filled into the target data unit; the target data unit is inserted into a preset unit position of the original video to obtain a video to be published, and the video to be published is uploaded to a server, so that the server can construct a first association relationship between the video to be published and an associated video corresponding to the device identification. In the above scheme, by performing hash mapping processing on multiple data units into which the original video has been divided to obtain a reference check value, the server can be provided with reference information for verifying whether the video data has been illegally tampered with or abnormally missing, so as to ensure the integrity and authenticity of the video to be published that needs to be associated. By encrypting the device identification and the reference check value to obtain encrypted content data, it can be ensured that the device identification and the reference check value are not stolen or tampered with during the video transmission process. By constructing a target data unit that conforms to a predefined unit type, and filling the encrypted content data into the target data unit, and inserting the target data unit into the preset unit position of the original video to obtain the video to be published, the encrypted content data for video association can be reasonably inserted without affecting the content playback of the original video, without affecting the original production process and data transmission process of the original video, reducing the complexity of association and improving processing efficiency.

[0097] Figure 6 A flowchart of another video association method including a process of performing hash mapping processing to obtain a reference check value is provided in an embodiment of the present application. Figure 6 As shown, the following steps are included:

[0098] Step S601: Obtain original video and device identification.

[0099] Step S602: respectively calculate hash values ​​of the multiple data units into which the original video has been divided, and accumulate the multiple hash values ​​corresponding to the multiple data units to obtain a reference check value.

[0100] Among them, hash algorithms such as MD5, SHA-1, SHA-256, etc. can be used to calculate the hash values ​​of multiple data units into which the original video has been divided, respectively, and this application does not limit this.

[0101] Step S603: encrypt the device identification and the reference check value to obtain encrypted content data.

[0102] Step S604: construct a target data unit that conforms to the predefined unit type, and fill the encrypted content data into the target data unit.

[0103] Step S605: insert the target data unit into the preset unit position of the original video to obtain the video to be published, and upload the video to be published to the server, so that the server can build a first association relationship between the video to be published and the associated video corresponding to the device identifier.

[0104] As mentioned above, by respectively calculating the hash values ​​of the multiple data units into which the original video has been divided, and accumulating the multiple hash values ​​corresponding to the multiple data units to obtain a reference verification value, the server can be provided with reference information for verifying whether the video to be released has been illegally tampered with or abnormally missing during the data transmission process, and whether the device identification is valid, thereby ensuring the integrity and authenticity of the video to be released.

[0105] Figure 7 A flowchart of another video association method including a process of constructing a target data unit that conforms to a predefined unit type is provided in an embodiment of the present application. Figure 7 As shown, the following steps are included:

[0106] Step S701: obtain the original video and the device identification, and perform hash mapping processing on the multiple data units into which the original video has been divided to obtain a reference check value.

[0107] Step S702: encrypt the device identification and the reference check value to obtain encrypted content data.

[0108] Step S703: query according to the video file format of the original video to determine the target field value of the associated unit type field.

[0109] In order to meet the video file format requirements of different application scenarios, the video file formats of the original videos produced by different video applications may be different, and the field values ​​of the unit type fields corresponding to the predefined unit type settings may be different. Therefore, it is necessary to query the relevant lists or mapping tables according to the video file format of the original video to determine the target field value of the associated unit type field. For example, for the original video in MP4 format, the corresponding unit type field is box-type, and the corresponding field value can be xxxx 1 For the original video in MOV format, the corresponding unit type field is atom-type, and the corresponding field value can be xxxx 2 Specifically, the developer can set the field value of the corresponding predefined unit type according to different video file formats, and this application does not limit this.

[0110] Step S704: construct a target data unit whose field value satisfies the unit type field and is the target field value according to the data size of the encrypted content data, and fill the encrypted content data into the target data unit.

[0111] Among them, the target data unit can include three parts: unit size, unit type and unit data. The unit size is the data size of the encrypted content data, the field value of the unit type field corresponding to the unit type is the target field value, and the unit data is the encrypted content data filled in.

[0112] Step S705: insert the target data unit into the preset unit position of the original video to obtain the video to be published, and upload the video to be published to the server, so that the server can build a first association relationship between the video to be published and the associated video corresponding to the device identifier.

[0113] As described above, by querying according to the video file format of the original video to determine the target field value of the associated unit type field, the field value of the predefined unit type corresponding to different video file formats can be effectively matched and determined, and by constructing a target data unit whose field value satisfies the unit type field as the target field value according to the data size of the encrypted content data, a custom data unit that matches the original video can be effectively constructed, and the encrypted content data for video association can be reasonably inserted without affecting the video content structure of the original video.

In the above scheme, by determining the target data unit that meets the predefined unit type from the multiple data units that the video to be released has been divided into, the target data unit containing the device identification that the client additionally constructs can be effectively identified. By decrypting the encrypted content data, the reference check value and the client's device identification can be obtained to ensure the security and reliability of the data source.
