[0007] Embodiment 1:

[0008] A method for fusion of infrared temperature measurement data, the method comprising:

[0009] S1, the splitting end sends a data transmission request to the reassembling end;

[0010] S2. The recombining end generates the asymmetric encryption key in response to the data transmission request, and sends the public key in the asymmetric encryption key to the splitting end;

[0011] S3, the split end uses the public key to encrypt the pre-generated symmetric encryption key;

[0012] S4. The recombinant end uses the asymmetric encryption private key to decrypt the symmetric encryption key generated by the split end;

[0013] S5, the splitting end encrypts the video data to obtain a transmission unit, and sends it to the reassembling end. The reassembling end uses the asymmetric encryption private key to decrypt the symmetric encryption key generated by the splitting end;

[0014] S6. The reassembly end uses the symmetric encryption key to parse the transmission unit to obtain the video data.

[0015] The splitting end (client) may be a node that splits, encrypts and sends H.264 encoded data, and such nodes include but are not limited to ordinary computers, smart phones, IoT devices and other terminals. The role of this node is to split, encrypt and send H.264 video encoded data, and the relevant code will be deployed on this node. The reorganization end (server) may be a node that reorganizes the data from the splitting end to restore it to the original complete data. The role of this node is to decrypt and reorganize the data from the splitting end, as well as handle some error situations, and the relevant code will be deployed on this node.

[0016] In a possible implementation, the symmetric encryption key can be a symmetric encryption key generated by the split end for the shard data, and the encryption key is used to symmetrically encrypt the shard data. The asymmetric encryption key can be a public key and a private key for asymmetric encryption generated by the recombinant end, and the public key is transmitted to the split end, the public key is used to encrypt the symmetric encryption key, and the private key is used to decrypt the symmetric encryption key encrypted by the public key.

[0017] In a possible implementation, the transmission unit includes an encrypted slice data sequence number, an encrypted slice data length, and an encrypted slice data pointer. During the parsing process, the video data can be obtained according to the encrypted slice data sequence number, the encrypted slice data length, and the encrypted slice data pointer.

[0018] In this implementation, for an H.264 encoded video file at the split end, the split end first obtains the asymmetric encryption public key from the reassembly end, then generates a symmetric encryption key by itself, and sends the asymmetric encryption key to the split end. Then, for the H.264 encoded video file to be transmitted, the split end splits each frame data according to the frame header feature (0x00000001 or 0x000001), thereby obtaining a number of fragmented data.

[0019] During the splitting process, each fragmented data is encrypted using a symmetric encryption key to obtain encrypted fragmented data. The splitting end encapsulates the encrypted fragmented data, adds a serial number tag to form a transmission unit, and transmits it to the reassembly end through a carrier. After receiving several transmission units, the reassembly end decrypts the encrypted data in the transmission unit using a symmetric encryption key, and reassembles according to the serial number in the transmission unit, and finally obtains the H.264 encoded data at the splitting end.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
