For the multiple hardwares information of itself, combination obtains the client device unique identification data；
Specifically, the first random data and the second random data that can obtain by these hardware informations and before carry out together
An equipment unique identification data is obtained after combination, is implemented as follows：
(1) client device can generate a string of random data (i.e. the first random data).
ClientRand=Rand ()；
A string of random data ClientRand are generated by calling system random function Rand.
(2) client device obtains the second random data from server；
In the present embodiment, server also will use random function (can random function identical with client) and generate a string
Random data ServerRand, and it is sent to client.
(3) client can obtain the multiple hardwares information of itself.
Such as IMEI, Serialno, CPUID, SystemModel etc..
(4) to finally obtain a string of combined client device unique identification data DeviceIdData.
DeviceIdData=ClientRand+ServerRand+IMEI+Serialno+CPUID+S ystemModel.

Further, the step S1044 is specifically included：
According to a variety of hard of first random data, second random data and the client device itself
The preset order of part information is combined sequentially into the client device unique identification data.
A common block chain must include some necessary data, so that one can verify block chain itself
Legitimacy, another is but also it is not easy to forge.Block chain data structure in the embodiment of the present invention then depends on
The data of client device unique identification information, so believing in data structure within a block comprising client device unique identification
Breath.Specifically, first block and second block are same data structure；
The data structure includes the block number of block, the cryptographic Hash of previous block, current time, calculates new block Hash
The number of front 0, random data, the cryptographic Hash of current block and block performance data in value；Area in second block
Block performance data includes the client device unique identification information.
It is implemented as follows：
Struct BlockData{
Int64 index；
String previousHash；
Int64 timestamp；
String data；
String zero；
String randdata；
String hash；
}
Wherein, index is used to indicate the block number of block, is usually incremented by since 0；PreviousHash indicates previous area
The hash value (cryptographic Hash) of block；Timestamp indicates current time stamp；Zero indicates to calculate front 0 in the hash value of new block
A data；Randdata then indicates random data, for being added in new block, so that its hash value calculated meets
0 number that server issues；Hash then indicates the hash value of the content of this current block；Data then indicates some data
Splice (i.e. above-mentioned block performance data), the content of this data field is then according to set by the function of completing required for block
Meter, is directed in the embodiment of the present invention, block performance data may include client device unique identification information and the visitor of user
Hardware information of family end equipment equipment, and the data information of application etc., after the design for having this block chain data structure, when
After receiving the newly generated block of other client devices, then it can be verified by the data to the inside.
Further, as shown in figure 4, further including in the method：
S105, client device receive the third block that target client device is sent, and include mesh in the third block
Mark the unique identification information of client device；
With the presence or absence of in the destination client in each block for the block chain that S106, client device detection locally save
The identical identification information of the unique identification information of equipment, if so, then determining that the target client device sets for illegitimate client
It is standby, the third block is not added in the block chain, if nothing, the third block is added to the block chain
In.
It also needs to design the algorithm for generating a new block by a block in the embodiment of the present invention.Each block chain
Client device can then receive the original block that server issues, new area then then can be generated according to original block
It block and is added in block chained list, is implemented as follows：
The data structure of a upper block has been got first, and next block is then the number according to a upper block
According to being generated.The name that a upper block is assumed in the present embodiment is prevblock, and the name of newly-generated block is
newblock。
(1) block number of new block is calculated.
Newblock.index=prevblock.index+1；
Then the block number of new block is that current block number adds 1.
(2) timestamp of new block is calculated.
Newblock.timestamp=time ()；
The timestamp of new block is then to obtain the current time.
(3) the hash value of a upper block for new block is calculated.
Newblock.previousHash=prevblock.hash；
The hash value of a upper block for new block is then the hash of the upper block obtained.
(4) data of new block are calculated.
Newblock.data=DeviceId+ClientRand+ServerRand+IMEI+Serial no+CPUID+
SystemModel+data；
When there is new client device to be added, then a new block can be generated, is broadcast in block chain, with notice
Everybody, has new client device to be added.This client then can be by equipment unique identification information that the client generates
The model information of DeviceId and the client device, the information such as IMEI, CPUID, and the data information one of new block is added
It rises and is put into the data of block chain, and this client device unique identification information DeviceId is that have the client according to oneself
Facility information be calculated, calculation method is then the calculation method in step (2).
(5) the randdata value of new block is calculated.
This randdata value is then that client generates at random, to gather together enough before the hash value that just entire new block calculates
Meet 0 number that server issues.
(6) the hash value of new block is calculated.
Newblock.hash=HASH (index+previousHash+timestamp+data+zero+randdata)；
The hash value of new block is then to have the index field and previousHash field and timestamp word of new block
Section and data field.
In the present embodiment, the HASH algorithm used is usually SHA-256 algorithm, naturally it is also possible to be calculated using other HASH
Method.
It is achieved that the algorithm that a new block is generated by a block through the above steps.
Generation for new block, can be in the client by Web broadcast to all block chains, and all clients
End is all the client of a block chain, all has and generates new block, and verifies the ability of new block, and the present embodiment
In algorithm be one be the unique identification information for carrying out managing customer end equipment using block chain, then the client of block chain is set
Then it can all go whether the client device unique identification information for verifying new block is one when for for receiving a new block
The client device unique identification information of a qualification, if not will not then be added in block chain, it is believed that this is a forgery
Client device unique identification information.So each block requires to carry out completeness check, it is implemented as follows：
It is common in client, be then that client device has had currently first for other blocks in addition to original block
Then block has received a new block, need to carry out validity judgement to new block.It is implemented as follows：
The name for also assuming that a block is prevblock, then has received the name of a newly-generated block
It is newblock.
(1) first determine whether its index is correct.
Newblock.index！=prevblock.index+1；
If the block number of new block is not the block number plus 1 of a upper block, illustrate that new block is illegal, directly
It connects and returns to block errors information.
(2) then judge the hash value of block.
Newblock.previousHash！=prevblock.hash
New area is thought if the hash value of a upper block for new block is not equal to the hash value of a upper block
Block is illegal, directly return block errors information.
(3) judge the hash value of new block.
The hash value of new block is the hash result of the entire data of new block.
HASH(Newblock.index+Newblock.previousHash+Newblock.timestamp+
Newblock.data+Newblock.randdata+Newblock.zero)！=Newblock.hash；
If the hash value of the data of the entire block of new block is not equal to new block hash value, then it is assumed that new area
