[0002] With the development of video encoding and transmission technology, various medical information platforms often use medical videos for technical explanations or medical diagnoses, leading to increasing emphasis on the copyright protection of medical video resources.

[0022] If the transformation unit to which authentication and decryption are performed is not the target transformation unit, then the video encoded bitstream is destroyed.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0046] Currently, medical video resources held by medical information platforms can be easily obtained through various means and channels, leading to video copyright theft. This makes it difficult to protect the professional copyrights and intellectual property rights of medical video resources. At present, the only solution to this problem is human intervention, specifically effective protection within high-traffic companies. However, this method has weak anti-theft capabilities and high costs.

[0047] To address the above problems, in one embodiment, such as Figure 1 As shown, a video encryption processing method is provided. Taking the application of this method on the server side as an example, the method includes the following steps:

[0048] 101. Obtain the video encoding data of the original video, wherein the video encoding data is obtained by compressing and encoding the original video, and the video encoding data contains multiple transform units.

[0049] Specifically, video encoded data can be obtained by compressing and encoding the original video using video encoding technology. Please refer to [link / reference]. Figure 2 , Figure 2 A video encoding flowchart using H.264 video encoding technology as an example is given, such as... Figure 2 As shown: The original video is used as the input signal. After transformation, scaling, and quantization, video encoded data including multiple transform units (TUs) is generated. Subsequently, the transform units, filter control data, motion data, and intra-frame prediction data are encoded using header information encoding and entropy encoding (CABAC) to generate an encoded bitstream, i.e., the video encoded bitstream. The receiving end decodes the video encoded bitstream to obtain the original video. In the embodiments of this application, the process data of the original video after transformation, scaling, and quantization, but before entropy encoding, can be obtained as video encoded data. Simultaneously, multiple transform units in the video encoded data are obtained as the basis for subsequent steps. It should be noted that this embodiment uses the H.264 video encoding process as an example for illustration; other different video encoding technologies are also applicable to this embodiment.

[0050] 102. Obtain the blockchain fingerprint and encrypt the blockchain fingerprint based on a preset encryption algorithm to obtain the authentication fingerprint, wherein the blockchain fingerprint and the fingerprint stripping data corresponding to the blockchain fingerprint are pre-stored in the blockchain.

[0051] The blockchain fingerprint and its corresponding fingerprint stripping data are pre-stored in the blockchain, and the fingerprint stripping data can be a binary address. Furthermore, the blockchain fingerprint can be a binary string, with a unique correspondence between it and the binary address. The binary address can be obtained by verifying and auditing the blockchain address on the blockchain. The blockchain fingerprint can be embedded in the transformation unit corresponding to the original video for purposes such as ownership verification, copyright protection, video integrity, anti-copying, and tracking. The blockchain fingerprint can only be stripped from the transformation unit based on the fingerprint stripping data in the blockchain, thus preventing other thieves from stripping the blockchain fingerprint from the video using forged fingerprint stripping data, ensuring the anti-theft capability of the video work. Simultaneously, after the decoder obtains the video encoded bitstream generated by video encoding technology from the original video and performs entropy decoding, if it detects the presence of a transformation unit with a blockchain fingerprint, it cannot perform further decoding to obtain the original video, thereby preventing thieves without fingerprint stripping data from decoding the video and avoiding the theft of the original video. After generating the blockchain fingerprint and the corresponding fingerprint stripping data, both can be added to the blockchain. When the original video needs to be encoded, the pre-generated blockchain fingerprint can be obtained to perform the subsequent encoding process.

[0052] Specifically, the encryption algorithm can be RSA encryption, generating an encryption public key and a decryption private key. By encrypting the blockchain fingerprint using the RSA-encrypted public key, an authentication fingerprint can be obtained. Further, when video decoding is required, a user with video viewing permissions uses the obtained decryption private key to authenticate and decrypt the authentication fingerprint, obtaining the blockchain fingerprint. This blockchain fingerprint is then verified on the blockchain. Once verified, fingerprint stripping data corresponding to this blockchain fingerprint is obtained. This fingerprint is then stripped in the transformation module, allowing for further decoding of the video to obtain the original video. Conversely, if a user does not have video viewing permissions, they cannot use the decryption private key and therefore cannot decode the original video.

[0053] 103. Select a target transformation unit from the plurality of transformation units, and embed the authentication fingerprint into the target transformation unit to obtain process video data.

[0054] In this process, after the original video undergoes transformation, scaling, and quantization, each frame of the resulting video encoded data will contain a corresponding number of transformation units.

[0055] Specifically, a predetermined number of transformation units can be selected from multiple transformation units in the acquired video encoded data as target transformation units for embedding the authentication fingerprint. Further, the authentication fingerprint is embedded into the selected target transformation units to obtain the process video data.

[0056] 104. Perform entropy encoding on the target video data to obtain a video encoded bitstream, and send the video encoded bitstream to the client so that the client can decode the video encoded bitstream based on the fingerprint stripping data to obtain the original video.

[0057] The client can be a client that sends a request to the server to play the original video. After receiving the playback request from the client, the server can send the encoded video bitstream to the client. Furthermore, the client can be a customized player from the video resource provider, integrating features to determine whether the user has permission to play the requested original video.

[0058] The video encryption method provided in this embodiment can set a blockchain fingerprint on the video resource. By verifying the blockchain fingerprint on the blockchain, unique fingerprint stripping data can be obtained. Only after stripping the blockchain fingerprint using the unique fingerprint stripping data can the video resource that can be decoded and viewed be obtained. Setting the fingerprint stripping data on the blockchain can ensure the uniqueness of the fingerprint stripping data, effectively preventing the fingerprint stripping data from being tampered with, thereby avoiding the theft of video resources and enhancing the anti-theft protection capability of video resources. Furthermore, this application can avoid deleting the blockchain fingerprint on the video resource, ensuring the traceability capability of video resource copies. In addition, encrypting the blockchain fingerprint of the video resource based on an encryption algorithm can ensure that users with video playback permissions can decrypt the blockchain fingerprint according to the encryption algorithm, obtain the blockchain fingerprint, and perform subsequent decoding operations, enhancing the authentication capability of video resource playback permissions and further enhancing the anti-theft protection capability of video resources.

[0059] In one embodiment, step 102 can be implemented as follows: First, obtain the blockchain fingerprint and a preset encryption public key and decryption private key. The decryption private key is used to authenticate and decrypt the authentication fingerprint to obtain the blockchain fingerprint. Further, the encryption algorithm can be the RSA encryption algorithm. Specifically, a pre-generated blockchain fingerprint can be obtained, and an encryption public key and decryption private key can be randomly generated based on the RSA encryption algorithm. Then, the decryption private key is sent to the client. The client can be a customized player from the video resource provider, used to decode and play video resources sent by the server. After receiving the decryption key, the client verifies the user's identity information to determine if the user has permission to play the video resource. If the user has permission to play the video resource, the obtained decryption private key is allowed to authenticate and decrypt the authentication fingerprint for subsequent video decoding; if the user does not have permission to play the video resource, the obtained decryption private key is not allowed to authenticate and decrypt the authentication fingerprint, preventing the user from playing the video. Finally, the blockchain fingerprint is encrypted based on the encryption public key to obtain the authentication fingerprint. In the embodiments of this application, the blockchain fingerprint is encrypted to obtain the authentication fingerprint, which can prevent users without video playback permissions from decrypting the authentication fingerprint into a blockchain fingerprint and obtaining the fingerprint stripping data on the blockchain in order to decode the video encoded bitstream into the original video, thus ensuring that the video resources are not stolen.

[0060] In one embodiment, the method for selecting a target transform unit from the plurality of transform units in step 103 is as follows: First, an identification identifier is set for all transform units in the video encoded data. Specifically, all transform units in the compressed and decoded video encoded data can be obtained, and a number identifier or location information identifier can be set for each transform unit so that each transform unit can be quickly located based on the number identifier or location information identifier during decoding. Then, a target transform unit is selected from the transform units, and the identification identifier corresponding to the target transform unit is sent to the client. The identification identifier corresponding to the target transform unit is used to enable the client to determine the target transform unit from all the transform units. Specifically, a preset number of transform units can be selected as target transform units from the transform units after setting the identification identifier, according to a preset number of transform units that need to embed authentication fingerprints. Further, the identification identifier corresponding to the target transform unit can be sent to the client. The client can be a customized player of the video resource provider, used to decode and play video resources sent by the server. After receiving the identification identifier corresponding to the target transform unit, the client will verify the user's identity information to determine whether the user has the permission to play the video resource. If the user has permission to play the video resource, they are allowed to use the identification identifier corresponding to the obtained target transform unit to filter the target transform unit embedded with the authentication fingerprint from other transform units. This allows for quick location of the target transform unit and faster authentication and decryption of the authentication fingerprint, thereby accelerating the decoding speed of the video resource. In the embodiments of this application, an identification identifier is set in the transform unit, and the identification identifier of the target transform unit with the embedded authentication fingerprint is sent to the client, enabling the client to quickly locate the target transform unit and increase the efficiency of video decoding.

[0061] In one embodiment, after step 104, the method further includes: First, monitoring the decoding result of the video encoded bitstream by the client. Specifically, the decoding result of the video encoded bitstream by the client can be monitored in real time through the network connection between the server and the client. Then, it is determined whether the video encoded bitstream has been decoded into the original video by the client. Finally, if the video encoded bitstream has been decoded into the original video by the client, the blockchain fingerprint and the fingerprint stripping data corresponding to the blockchain fingerprint in the blockchain are updated, and based on the updated blockchain fingerprint, the step of encrypting the blockchain fingerprint based on a preset encryption algorithm to obtain the authentication fingerprint is executed. Specifically, if the client successfully decodes the video encoded bitstream into the original video, the blockchain fingerprint and the fingerprint stripping data corresponding to the blockchain fingerprint are re-acquired, wherein the blockchain fingerprint and fingerprint stripping data are blockchain fingerprints and fingerprint stripping data that have never been used at the current location to ensure the validity of the blockchain fingerprint and fingerprint stripping data. Furthermore, the blockchain fingerprint can be encrypted again based on the encryption algorithm to obtain the authentication fingerprint. In the embodiments of this application, after the client decodes the video encoded bitstream into the original video, the blockchain fingerprint and fingerprint stripping data used in the original video encoding process are updated to prevent the fingerprint stripping data from being reused or used to decode other video encoded bitstreams obtained from the original video encoding, thereby preventing the theft of video resources.

[0062] The video encryption processing method provided in this embodiment can set a blockchain fingerprint on the video resource. By verifying the blockchain fingerprint on the blockchain, unique fingerprint stripping data can be obtained. Only after stripping the blockchain fingerprint using the unique fingerprint stripping data can the video resource that can be decoded and viewed be obtained. Setting the fingerprint stripping data on the blockchain can ensure the uniqueness of the fingerprint stripping data, effectively preventing the fingerprint stripping data from being tampered with, thereby avoiding the theft of video resources and enhancing the anti-theft protection capability of video resources. At the same time, this embodiment can set an identifier for the target transformation unit, speeding up the decoding efficiency of the video encoded bitstream by the client. Furthermore, this application can avoid deleting the blockchain fingerprint on the video resource, ensuring the traceability capability of the video resource copy. In addition, encrypting the blockchain fingerprint of the video resource based on an encryption algorithm can ensure that users with video playback permissions can decrypt the blockchain fingerprint according to the encryption algorithm, obtain the blockchain fingerprint, and perform subsequent decoding operations, enhancing the authentication capability of video resource playback permissions. Furthermore, the server can update the blockchain fingerprint and fingerprint stripping data based on the usage of the original video, preventing the fingerprint stripping data from being reused or used to decode other video encoded bitstreams obtained from the original video encoding, thus further enhancing the anti-theft protection capabilities for medical video resources.

[0063] In one embodiment, such as Figure 3 As shown, a video encryption processing method is provided. Taking the application of this method to a client as an example, the method includes the following steps:

[0064] 201. In response to the playback request of the original video, receive the video encoded bitstream corresponding to the original video from the server, and perform entropy decoding on the video encoded bitstream to obtain the process video data.

[0065] The client can be a customized player for the video resource provider, used to decode and play video resources sent by the server. It also receives user identity information and determines the user's video playback permissions.

[0066] Specifically, based on the user's request to play the original video, the server can send and retrieve the video encoded bitstream corresponding to the original video, and then perform entropy decoding on the video encoded bitstream to obtain the process video data.

[0067] 202. Determine the target transformation unit in the process video data, and authenticate and decrypt the authentication fingerprint in the target transformation unit based on a preset decryption algorithm to obtain the blockchain fingerprint.

[0068] The target transformation unit is a transformation unit embedded with an authentication fingerprint.

[0069] Specifically, after obtaining the process video data, each transform unit in the process video data can be verified to see if an authentication fingerprint is embedded in the transform unit. Transform units with embedded authentication fingerprints are identified as target transform units for subsequent authentication and decryption. Furthermore, the decryption algorithm can be the RSA algorithm, using the decryption private key obtained from the server to authenticate and decrypt the authentication fingerprint, thus obtaining the blockchain fingerprint.

[0070] 203. Verify the blockchain fingerprint and obtain the fingerprint stripping data corresponding to the blockchain fingerprint on the blockchain.

[0071] Specifically, by verifying and auditing the blockchain fingerprint on the blockchain, fingerprint stripping data corresponding to that blockchain fingerprint can be obtained.

[0072] 204. Based on the fingerprint stripping data, perform fingerprint stripping operation on the target transformation unit of the process video data to obtain video encoded data, and decode the video encoded data to obtain the original video.

[0073] The decoding process of the original video is the reverse operation of the original video encoding. After entropy decoding of the video encoded bitstream, the resulting process video data contains the target transform unit. Authentication decoding of the authentication fingerprint in the process video data yields the blockchain fingerprint embedded in the target transform unit, allowing fingerprint stripping data to be obtained from the blockchain. Furthermore, after stripping the blockchain fingerprint based on the fingerprint stripping data, quantized video encoded data can be obtained. The original video can then be decoded from the video encoded data and other information obtained from the video encoded bitstream.

[0074] Specifically, stripping the blockchain fingerprint from the target transformation unit yields video encoded data that can be decoded into the original data. Further decoding of the video encoded data yields the original video.

[0075] The video encryption processing method provided in this embodiment can decode the video encoded bitstream in combination with the decryption private key to obtain fingerprint stripping data and remove the blockchain fingerprint embedded in the target transformation unit. It can quickly decode the video encoded bitstream sent by the server to obtain the original video that the user wants.

[0076] In one embodiment, the method for determining the target transformation unit in the video data in step 202 is as follows: First, the identification identifier corresponding to the target transformation unit sent by the server is received. Then, the user's identity information is detected to determine whether the user has permission to use the identification identifier corresponding to the target transformation unit. The user's identity information can be registration information, payment information, and permission information that can determine whether the user has permission to access the original video. Specifically, the user's identity information and preset identity information with the right to use the original video can be used for verification to determine whether the current user has permission to use the original video. If the user has permission to use the original video, it is determined that the user has permission to use the identification identifier corresponding to the target transformation unit. Conversely, if the user does not have permission to use the original video, it is determined that the user has not used the identification identifier corresponding to the target transformation unit. Finally, if the user has permission to use the identification identifier corresponding to the target transformation unit, the target transformation unit is determined from the transformation units based on the identification identifier corresponding to the target transformation unit. Conversely, if the user does not have permission to use the identification identifier corresponding to the target transformation unit, the use of the identification identifier corresponding to the target transformation unit sent by the server is prohibited. The identification identifier corresponding to the target transformation unit is set by the server for the transformation unit embedding the authentication fingerprint. Specifically, if the user has permission to use the identification identifier corresponding to the target transformation unit, the location of the transformation unit embedding the authentication fingerprint can be quickly located based on the identification identifier, enabling rapid subsequent authentication fingerprint decryption and accelerating decoding efficiency. Conversely, if the user does not have permission to use the identification identifier corresponding to the target transformation unit, multiple transformation units need to be judged one by one to locate the target transformation unit. In the embodiments of this application, obtaining the identification identifier corresponding to the target transformation unit and using the identification identifier corresponding to the target transformation unit based on user permissions enables rapid location of the target transformation unit and accelerates video decoding efficiency.

[0077] In one embodiment, the method for obtaining a blockchain fingerprint by authenticating and decrypting the authentication fingerprint in the target transformation unit based on a preset decryption algorithm in step 202 is as follows: First, obtain a decryption private key from the server. Then, detect the user's identity information to determine whether the user has permission to use the decryption private key to authenticate and decrypt the authentication fingerprint. The user's identity information can be registration information, payment information, and permission information that can determine whether the user has permission to access the original video. Specifically, the user's identity information and preset identity information with the right to use the original video can be used for verification to determine whether the current user has permission to use the original video. When the user has permission to use the original video, it is determined that the user has permission to use the decryption private key to authenticate and decrypt the authentication fingerprint. Conversely, if the user does not have permission to use the original video, it is determined that the user does not have permission to use the decryption private key to authenticate and decrypt the authentication fingerprint. Finally, if the user has permission to use the decryption private key to authenticate and decrypt the authentication fingerprint, then based on the decryption private key, the authentication fingerprint is authenticated and decrypted to obtain the blockchain fingerprint. Accordingly, if the user does not have permission to use the decryption private key to authenticate and decrypt the authentication fingerprint, then using the decryption private key to authenticate and decrypt the authentication fingerprint is prohibited. In the embodiments of this application, the system can receive the encryption private key sent by the server and determine whether the user has permission to use the original video based on the user's identity information. When the user has permission to use the original video, the authentication fingerprint is authenticated and decrypted based on the decryption private key to obtain the blockchain fingerprint for subsequent decoding operations, preventing unauthorized users from stealing the video resources.

[0078] In one embodiment, after step 202, the method further includes: First, monitoring the decryption result of the authentication fingerprint in the target transformation unit. Specifically, during the decoding of the authentication fingerprint, it can be monitored in real time whether the authentication fingerprint being decrypted into a blockchain fingerprint. Then, it is determined whether the decryption result of the authentication fingerprint in the target transformation unit is the blockchain fingerprint. Specifically, it can be determined whether the authentication fingerprint is decrypted into a blockchain fingerprint based on the decryption private key. Further, if it is determined based on the user's identity information that the user has permission to use the original video, the client will use the decryption private key to decrypt the authentication fingerprint to obtain the blockchain fingerprint. Conversely, if it is determined based on the user's identity information that the user does not have permission to use the original video, and the user attempts to decrypt the authentication fingerprint through the client, it can be determined that the user is attempting to crack the blockchain fingerprint to steal the original video. Because the fingerprint stripping data is in the blockchain, the uniqueness of the fingerprint stripping data can be guaranteed, and the authentication fingerprint can only be decrypted using the decryption private key. Therefore, if the user attempts to crack the authentication fingerprint using other means, the blockchain fingerprint will not be obtained. Finally, if the decryption result of the authentication fingerprint in the target transformation unit is not the blockchain fingerprint, the video encoded bitstream is destroyed. Specifically, if the authentication fingerprint is not decrypted into a blockchain fingerprint, it indicates that a user without video access rights is using other technical means to crack the blockchain fingerprint. In this case, the video encoded bitstream received from the server is destroyed to prevent malicious theft of video resources. In the embodiments of this application, when it is discovered that a user has attempted to crack the blockchain fingerprint, the video encoded bitstream can be destroyed in a timely manner, completely avoiding the possibility of cracking the authentication fingerprint and thus stealing video resources.

[0079] In one embodiment, after step 202, the method further includes: first, monitoring the transformation units undergoing authentication and decryption. Specifically, it can monitor in real time which transformation units in the process video data are undergoing authentication and decryption operations. Then, it determines whether the transformation unit undergoing authentication and decryption is the target transformation unit. If the transformation unit undergoing authentication and decryption is not the target transformation unit, the video encoded bitstream is destroyed. Specifically, for users with permission to use the original video, the target transformation unit with embedded authentication fingerprint is directly located among multiple transformation units based on the identification identifier corresponding to the target transformation unit obtained from the server, without decrypting transformation units without embedded authentication fingerprint. For users without permission to use the original video, when they decrypt the authentication fingerprint in the process video data, since they cannot locate the target transformation unit among many transformation units, they will perform authentication and decryption on each transformation unit to filter out the target transformation unit. When the client performs authentication and decryption on a non-target transformation unit, it can be determined that the user is using other technical means to crack the blockchain fingerprint. At this time, the video encoded bitstream can be destroyed to prevent the video resources from being maliciously stolen. In the embodiments of this application, when it is discovered that a user has attempted to crack the blockchain fingerprint, the video encoding bitstream can be destroyed in a timely manner to completely prevent the possibility of cracking the blockchain fingerprint and thus stealing video resources.

[0080] The video encryption method provided in this embodiment can determine whether a user has permission to use the original video based on the user's identity information. When it is determined that the user has permission to use the original video, the target video data can be quickly located according to the identification identifier corresponding to the target transformation unit, and the blockchain fingerprint can be decrypted using the obtained decryption private key to further decode and obtain the original video. Furthermore, when it is determined that the user has attempted to crack and decode the original video, the video encoding bitstream will be destroyed immediately to prevent the theft of medical video resources.
