In order to which the interactive process of video anti-counterfeiting system interior joint is better described, Fig. 2 shows a kind of video anti-counterfeiting systems
The flow diagram of interactive process, wherein the following steps are included:
Step S202, first node obtain video flowing and are segmented to video flowing；For the N section video flowing obtained after segmentation
The first check value is generated respectively, and N is positive integer.
The video flowing that first node obtains can be to be obtained from camera-shooting and recording device, is also possible to store video flowing from other
Terminal in obtain.After first node obtains video flowing, by analyzing the information of video flowing, if acquired video flowing
Size be more than preset value, just acquired video flowing is compressed, video flowing is segmented after compression, make every section view
The size of frequency stream meets preset value, and every section of video flowing that size can be met preset value by first node generates corresponding first school
Test value.
Specifically, first node can generate the first verification corresponding with i-th section of video flowing according to specified hash function
Value, wherein the unique identification whether corresponding first check value of i-th section of video flowing is tampered as i-th section of video flowing of identification.
Wherein, hash function is the output by hashing algorithm by Input transformation at regular length, which is exactly to hash
Value.Briefly hash function is exactly a kind of function of the message compression by random length to a certain regular length.First node
Corresponding first check value of i-th section of video flowing is generated by specified hash function, this specifies hash function such as: MD5
(Message-Digest Algorithm, Message Digest 5), wherein the eap-message digest of MD5 file is exactly to pass through Hash letter
What number was calculated.Regardless of file size, its hash function calculate the result is that the numerical value of a regular length, MD5
This hash function is an irreversible one-way function.Such as the byte serial of random length is mapped as a 128bit by MD5
Numerical value, be highly difficult by the anti-original character string that pushes away of the numerical value of this 128bit, even if obtaining source program and algorithm, also without
The value of one MD5 is switched back to original character string by method.This specifies hash function for another example: SHA (Secure Hash
Algorithm, secure hash algorithm), this secure hash algorithm, which can calculate, to be arrived corresponding to a digital massage, and length is solid
Fixed eap-message digest, and if input message it is different, the probability of corresponding kinds of characters string is very high.
Using highly-safe hash algorithm, when such as MD5, SHA, two different files are almost impossible obtain it is identical
Hash result.Therefore, video flowing is indicated using the first check value that above-mentioned hash function generates, once video flowing is modified,
It will be detected.
Step S204, first node filter out selected second node from least one second node, and to selected second
Node sends i-th section of video flowing and corresponding first check value of i-th section of video flowing in N sections of video flowings, and i is less than or equal to N
Any positive integer.
Specifically, first node, when filtering out selected second node from least one second node, can first to
At least one second node sends the second instruction message respectively, and the second instruction message indicates that at least one second node provides respectively
The corresponding proof of work of i-th section of video flowing；Different second nodes calculates the difficulty of the corresponding proof of work of i-th section of video flowing
Degree is different.The second node for successfully calculating the corresponding proof of work of i-th section of video flowing is determined as selected second node.
Wherein, proof of work refers to the proof of workload, and proof of work is that second node is required to carry out some time-consumings
Complex calculation appropriate is simultaneously sent to first node, and answer can quickly be checked by first node, and first node can basis
Second node amount of calculation proves the consumed time etc., and selected second node is selected from from second node and stores i-th section
Video stream information and corresponding first check value.Time, equipment and the energy of consumption can be remembered as Cost of Guarantee, first node
Recording second node amount of calculation proves the information of consumed time, equipment and the energy, to ensure that selected second node is to need
I-th section of Video stream information and corresponding first check value are wanted, simultaneously because providing i-th section of Video stream information and corresponding first
Be to the loss of equipment, time and the energy when proof of work of check value it is very big, first node can select equipment, the time and
The loss of the energy all maximum selected second node stores i-th section of Video stream information and corresponding first check value, workload
Proof ensure that selected second node will not distort i-th section of video flowing letter after obtaining i-th section of Video stream information from first node
Breath, because in this case, the loss to equipment, time and the energy is huge, even if this selected second node is distorted
I-th section of Video stream information, third node also can judge i-th section of video by the second check value of generation in access later
Stream information is tampered.
Wherein, selected second node is at least two second node, in this way when selected second node corresponding one
The video flowing that a server occurs in delay machine or one of them selected corresponding server of second node is tampered, and can also be protected
The integrality and authenticity of the i-th section of Video stream information recorded in card block chain network.
The difficulty that different second nodes calculates the corresponding proof of work of i-th section of video flowing is different, proof of work
What difficulty can be adjusted according to previous piece of time-consuming dynamic, the difficulty that proof of work generates can reflect in block chain network
The quantity of second node adjusts the redundancy backup number of every section of video flowing according to the number of nodes in network, but should at least have one

Step S208, third node obtain in N sections of video flowings from from j-th of selected second node in selected second node
I-th section of video flowing and corresponding first check value.
The first instruction message that third node is sent according to selected second node finds i-th section of video flowing of storage and the
The selected second node of j-th of one check value, j-th of selected second node are any one storages i-th in selected second node
The node of section video flowing and the first check value.
Step S210, third node generate corresponding second check value of i-th section of video flowing.
I-th section of video flowing that third node will acquire generates corresponding second check value of i-th section of video flowing, the second verification
The principle of the generating process of value and the generating process of the first check value be it is identical, may refer to description above here.
Step S212, when third nodal test is corresponding with i-th section of video flowing to corresponding first check value of i-th section of video flowing
The second check value be it is inconsistent when, determine from j-th of selected second node obtain i-th section of video flowing be tampered, j is positive
Integer.
When third nodal test goes out corresponding first check value of i-th section of video flowing the second school corresponding with i-th section of video flowing
It tests value to be consistent, then can determine acquisition is i-th section of video flowing being not tampered with.
When third nodal test goes out corresponding first check value of i-th section of video flowing the second school corresponding with i-th section of video flowing
Test value be it is inconsistent, then can determine acquisition is i-th section of video flowing being tampered.Further, third node sends the
Three instruction messages obtain i-th section of video at j-th of selected second node to other nodes in block chain network, other nodes
The message that stream is tampered.
Further, when j-th of selected second node receives third instruction message, j-th of selected second node is also
J-th of selected second node can be searched and be directed to the log information that i-th section of video flowing generates, log information includes i-th section of view
Frequency flows carried out historical operation information, inquires the time and specific operation information that i-th section of video flowing is tampered.
Step S214, third node determine that the i-th section of video flowing obtained from j-th of selected second node is tampered it
Afterwards, other selected second nodes from selected second node in addition to j-th of selected second node obtain i-th section of video flowing.
