Further, in order to reduce the interaction times of video monitoring equipment and video monitoring server, video monitoring equipment can according to the multiple original sequence number of self-encryption Summing Factor, once ask multiple encryption key to video monitoring server, respectively corresponding video monitoring data is encrypted to utilize multiple encryption key.
Such as, video monitoring equipment is by all original sequence number 1 between encryption factor aa57b525179bda9 and 12:00 to 13:00,86,122,9, once send to video monitoring server, the time point of this reception of interocclusal record when video monitoring server is current according to self, and preserve the time point of this reception and the corresponding relation of first original sequence number, thus determine the corresponding relation of other original sequence numbers in all original sequence number that video monitoring equipment sends except first original sequence number and time point.Video monitoring server is according to cryptographic algorithm, dynamic calculation goes out the encryption key that between 12:00 to 13:00, all original sequence numbers are corresponding respectively, and the encryption key that original sequence numbers all between 12:00 to 13:00 are corresponding is respectively returned to video monitoring equipment, respectively video monitoring data is encrypted according to multiple encryption key to make video monitoring equipment.
Step 204: video monitoring equipment is encrypted video monitoring data according to described encryption key.
In embodiments of the present invention, NALU (Network Abstract Layer Unit, the network abstraction layer unit) type of the video monitoring data of video monitoring equipment is defined, wherein, defines NALU type in H264 agreement, as shown in Figure 4.Wherein, when NALU type is 0 or 24 ~ 31, the content of NALU is not specified, and when NALU type is 13 ~ 23, retains the content of NALU, and when NALU type is 1 ~ 12, NALU content is given content.The embodiment of the present invention can set NALU type, and as 30, this NALU content can comprise the type code of 8bit and the original sequence number of 64bit.
Such as, one section of original video monitor data is: 00 00 00 01 67 42 00 1E F1 61 62 62 00 00 00 01 68 C8 A1 43 88 00, wherein, 00 00 00 01 is the beginning label of NALU, and 67 42 00 1E F1 61 62 62 are the RBSP (raw byte sequence layer) of NALU.By the original sequence number of the 64bit of above-mentioned data, as 12 34 56 78 12 34 56 78 12 34 56 78 12 34 56 78 add in above-mentioned original video monitor data, the video monitoring data after interpolation is: 00 00 00 01 1E 00 12 34 56 78 12 34 56 78 12 34 56 78 12 34 56 78 67 42 00 1E F1 61 62 62 00 00 00 01 68 C8 A1 43 88 00.Wherein, 1E 00 is NALU head, for identifying the type of NALU.Original sequence number is added on after this NALU type by video monitoring equipment, recycles encryption key afterwards and is encrypted video monitoring data.
Step 205: video monitoring client terminal obtains video monitoring data, and reads the original sequence number in video monitoring data.
Wherein, the mode of video monitoring client terminal acquisition video monitoring data comprises: 1. to video monitoring equipment acquisition request live video monitor data; 2. to video monitoring equipment acquisition request history video monitoring data; 3. obtain video monitoring data by copy mode.

Wherein, Authority Verification comprises the following steps:
A, verifies that described current login user identity is legal.
Such as, the current login user identify label of video monitoring client terminal is: zhangsan.Video monitoring server determines whether self preserves this User Identity, if so, shows that current login user identity is legal; Otherwise illegal, and ignore the request of this video monitoring client terminal.
B, verifies that current login user has the authority of the corresponding video monitoring data of accessing video watch-dog.
Such as, current login user is designated zhangsan, to the video monitoring data that the video monitoring server request access encryption factor is the video monitoring equipment of aa57b525179bda9, video monitoring server, according to the authority configuration of self, determines whether zhangsan has permission this video monitoring equipment of access.
C, verifies that current login user has the authority of the corresponding time video monitoring data of accessing video watch-dog.
Such as, current login user is zhangsan, to the video monitoring data of 1 day October in 2014 between 12:00-13:00 that the video monitoring server request access encryption factor is the video monitoring equipment of aa57b525179bda9, video monitoring server, according to the authority configuration of self, determines whether zhangsan has permission this video monitoring equipment of access.
Further, to the checking of this condition c, the swindle of video monitoring client terminal can be prevented, such as, active user is zhangsan, the request access encryption factor is the video monitoring data on January 1st, 2014 in the video monitoring equipment of aa57b525179bda9, wherein, the authority of video monitoring server is configured to the video monitoring data that zhangsan has permission the 1 day January in 2014 of this video monitoring equipment of access, if zhangsan is according to the original sequence number of video monitoring data on January 1st, 2014, to the decruption key that the video monitoring data in this video monitoring equipment of video monitoring server request on January 2nd, 2014 is corresponding, video monitoring server is according to sequence number original in cipher key relation table and the corresponding relation of time, the configuration that defines the competence is that zhangsan does not have authority to access the video monitoring data in the 2 days January in 2014 of this video monitoring equipment, therefore the request of this video monitoring client terminal is ignored.
It should be noted that, video monitoring equipment by original sequence number and encryption the factor to video monitoring server encryption key request time, video monitoring server preserves the corresponding relation of the time of original sequence number and this original sequence number of reception, the time interval generating this original sequence number due to time of the original sequence number of this reception and video monitoring equipment is relatively little, and generate an original sequence number every preset time period, and the time interval that video monitoring server receives between two original sequence numbers is identical with the time interval generating two original sequence numbers, therefore the time of this original sequence number will can be received as the time generating this original sequence number.Therefore video monitoring server preserves the corresponding relation that original sequence number and server receive the original sequence number time.
In addition, video monitoring equipment is when utilizing original sequence number to video monitoring server request decruption key, video monitoring server needs receive the corresponding relation of original sequence number time according to the original sequence number of self preserving and server, determine that whether the original sequence number of video monitoring equipment and corresponding time correct, thus prevent video monitoring equipment in the corresponding time inaccurate and artificially revised cause dangerous.
When above-mentioned three steps are all verified, show that Authority Verification is legal.Otherwise video monitoring server ignores the request of this video monitoring client terminal.Step 207: after Authority Verification is legal, video monitoring server returns decruption key.
After Authority Verification is legal, video monitoring server, according to the cipher key relation table self preserved, utilizes decipherment algorithm, generating solution decryption key, and the decruption key that the video monitoring data of being accessed by video monitoring client terminal is corresponding returns to video monitoring client terminal.
Step 208: video monitoring client terminal is decrypted video monitoring data according to decruption key.
In order to reduce the interaction times between video monitoring client terminal and video monitoring server, video monitoring client terminal also according to current login user identify label and multiple original sequence number, can once ask multiple encryption key to video monitoring server.
According to such scheme, video monitoring equipment generates original sequence number according to the corresponding Time dynamic of video monitoring data, and according to self-encryption Summing Factor original sequence number request dynamic encryption key, the original sequence number of this encryption key and video monitoring data and to encrypt the factor corresponding, this video monitoring data is got at video monitoring client terminal, after needing video monitoring server legal to its Authority Verification, just return the decruption key of this video monitoring data.Thus ensure that the fail safe of video monitoring data.
