Enterprise UE terminal 12 is to realize the tie communicated between personal user's terminal and server 13, enterprise UE terminal
12 are authenticated by server 13.Enterprise UE terminal 12 will not only receive the field to be written of personal user's terminal transmission,
Also needing to receive enterprise customer (has and provides the user of bill obligation for personal user, for example, it may be selling businessman) input
Field to be written.Server 13 is that enterprise UE terminal 12 is reserved with corresponding information input interface, passes through enterprise customer's end
End 12 can directly access server 13, detailed process are as follows: enterprise UE terminal 12 leads to according to the request of personal user's terminal 11
The second communication network access server 13 is crossed, so that the solicited message for carrying the field to be written be connect by information input
Mouth is input to server 13.Since different enterprise UE terminals 12 is corresponding with different information input interfaces, enterprise uses
Family terminal 12 can not need to send the identity information of itself again, certainly, even if no need to send certainly for enterprise UE terminal 12
The identity information of body, server 13 need the interface message and enterprise according to information input interface in follow-up treatment process
The corresponding relationship of the identity information of industry user terminal obtains the identity information of enterprise UE terminal 12, and participates in subsequent information
Processing is to be traced.It should be noted that enterprise UE terminal 12 is also not the real terminal for generating bill, also it is
Play the role of intermediary.It is to be understood that the enterprise UE terminal 12 in the application includes but is not limited to have by taking
Smart phone, tablet computer, desktop computer and the wearable device of information input interface etc. that business device 13 provides.
Server 13 can be the private server for specially realizing a certain single business, and being also possible to one can be real
The generic server of existing multiple business, does not influence the realization of technical scheme.Under normal conditions, server 13 is dedicated
Server is only used for realizing the function of access block chain network 14.In the application, personal user's terminal 11 and enterprise customer are whole
End 12 all cannot directly access block chain network, need by server 13, that is to say, that block chain network 14 licenses to service
Device 13, each enterprise UE terminal 12, which is required to just to be written into field by server 13, is transmitted to block chain network 14, and
Cannot data interaction individually be carried out with block chain network 14.Server 13 is usually to have multiple, each server and multiple enterprises
These fields are sent to block chain to receive the field to be written that each enterprise UE terminal 12 is sent by the communication of user terminal 12
Network 14.In specific implementation, server 13 obtains being sent by enterprise UE terminal 12 to be written by the second communication network
Field.
Server 13 has private key with the legal identity for authentication server 13, before being written into field cochain, needs
Server 13 is wanted to be encrypted to obtain signed data to the corresponding Hash result of field to be written by the private key of itself, then again
Signed data is back to block chain network 14.Block chain network 14 can carry out signed data using the public key of the server 13
Decryption, to obtain Hash result, then judges whether the Hash result is consistent with the Hash result for being sent to server 13, such as
Fruit is consistent, show that the field to be written of wanted cochain is correct, and is sent by legal server, is completed with this to label
The sign test of name data.It will be apparent that the process of sign test not only ensure that the accuracy of field to be written also assures field to be written
Source legitimacy.
In addition, server 13 can also carry out the detection of sensitive information to field to be written, it is equivalent to a kind of detection in advance,
If detect that field to be written does not include sensitive information, then it is written into field and is sent to block chain network 14.It can manage
Solution ground is that non-sensitive information database used in server 13 can be with non-sensitive information database used in block chain network 14
It is identical, in addition, the database can be local data base, it is also possible to third party database.It is to be understood that the present embodiment
In server 13 include but is not limited to Cloud Server, physical server and virtual server etc..
Block chain network 14 be usually include multiple block chain nodes 140, each block chain node includes multiple areas
Block chain, for storing data.In fact, can individually be deposited by a target block chain node 141 in block chain network 14

Business device 13 is reserved with interface of making out an invoice, and is used for issued notes, and target block chain node 141 obtains server by third communication network
13 fields to be written sent by interface of making out an invoice.Target block chain node 141 after getting the field to be written, firstly,
The detection that sensitive information is carried out to the field to be written, then carries out sign test to the signed data of server 13 again, finally, testing
Label carry out uplink operation after passing through, so that the field to be written comprising sensitive information be avoided to store to block chain network 14.In
Used non-sensitive information database can be the local data base established in block chain network 14 in detection process, can also be with
It is to be obtained from third party database by target block chain node 141.
The process of sign test is specifically included that when target block chain node 141 judges that field to be written does not include sensitive information
When, Hash operation can be carried out to field to be written and obtain Hash result, Hash result is then back to server 13 again, is serviced
Device 13 encrypts Hash result to obtain signed data after receiving Hash result by the private key of itself.Server 13
Signed data is back to target block chain node 141, target block chain node 141 is by the public key of server 13 to number of signature
According to being decrypted to obtain the Hash result in signed data, and judge the Hash result the phase one whether Hash result issues with it
It causes, if unanimously, illustrating that current server 13 is legal server and field to be written is not tampered with, sign test passes through.
After sign test passes through, the Hash result that target block chain node 141 can be written into field is committed to any area
Block chain node 140, for the Hash operation result submitted after the success cochain of either block chain node 140, the Hash result will
It is quickly transferred to other block chain nodes 140 within grade period second to be saved, each block chain node 140 passes through collaboration
Cooperation, maintains full dose director data, this process is considered as success of making out an invoice.Under normal conditions, target block chain node 141 will also
The successful information of cochain is back to server 13, can also be back to enterprise UE terminal 12, enterprise customer by server 13 again
Terminal 12 is back to personal user's terminal 11.
In the application, in addition to can recorde block-identified symbol, the information of bill, ticket in the either block of block chain network 14
According to generate operation note, binary tree root Hash and with except Hash result, can also further record block chain mark and
The information such as block chain account address.
After the block-identified symbol is mentioned above either referring to the block head progress Hash processing to a upper block
Obtained identifier may also mean that the block height of current block；The information of bill may include the field to be written, ticket
According to unique ID, the unique ID of enterprise UE terminal, server ip address, server public key etc.；The bill generates operation note
It may include personal user, enterprise customer, the corresponding operation of server and corresponding timestamp etc.；The binary tree specifically can be with
It is Merkle tree；The block chain identifies the mark for characterizing current block chain, can be adapted for that there are a variety of different blocks
The needs of chain apply the scene across chain technology；The block chain account address is that registration user obtains after registering block chain account
Address information, registration process can specifically include: after the Account Registration information for getting registration user, for registration user's creation
Account private key, and account public key corresponding with account private key is generated using elliptic curve, then calculated using uni-directional hash

Fruit enterprise UE terminal has carried out compression processing to all fields to be written, then corresponding server is needed according to corresponding decompression
Contracting method unzips it the field to be written that compression processing is crossed.
S107: the field to be written is sent to block chain network by the interface of making out an invoice of block chain network by server.
S108: block chain network judges whether the field to be written includes the sensitive information.
In the present embodiment, block chain network needs to carry out each field to be written the detection of sensitive information, prevent include
The problem of can not being modified after the field cochain to be written of sensitive information.
Non-sensitive information database can be locally created in block chain network, include multiple sensitive informations in the database,
When detecting sensitive information, a certain sensitive information or a certain field to be written are missed in order to prevent, can be using the side of double traversals
The whole fields to be written of formula, i.e. traversal and the mode for traversing whole sensitive informations, for example, in particular order, from first
A field to be written starts, and successively judges whether to include first sensitive information in non-sensitive information database, if comprising,
Then illustrate that current field to be written includes sensitive information, otherwise judges whether to include next in non-sensitive information database
Sensitive information, until each of non-sensitive information database sensitive information both participates in judgement, then the identical method of use is sentenced
Disconnected second field to be written, until all fields judgement to be written finishes.
It is to be understood that the mode of above-mentioned judgement is carried out to all fields to be written and whole sensitive informations
Judgement, be advantageous in that, detection sensitive information it is more accurate, still, workload be also it is huge, especially sensitive information compared with
When more, become apparent.Based on this, sensitive information can also be divided, be divided multiple sensitive informations according to partitioning standards
It for several sensitive information groups, and is the label information of each group of setting group, likewise, block chain network is obtaining word to be written
Duan Shi obtains the label information of each field to be written according to the partitioning standards being previously mentioned, and according to the mark of each field to be written
Information is signed, the filtering of sensitive information is carried out in corresponding sensitive information group, referring specifically to table 1.As shown in table 1, sensitivity is believed
Sensitive information in breath database is divided into 4 sensitive information groups, and each sensitive information group has the label information of itself, each
The quantity of sensitive information in sensitive information group may be identical, it is also possible to different.It is to be understood that table 3 is merely possible to one
Kind concrete application scene is described, and the listed quantity of sensitive information group and the quantity of sensitive information are not unique reality
Apply mode.In addition, different partitioning standards may cause the same sensitive information with two or more label informations, make
It obtains the sensitive information to occur in different sensitive information groups, this is also satisfactory, not the realization of influence technique scheme.
Table 1
Block chain network is when judging each field to be written, if any field to be written includes sensitive information,
Then illustrate that other fields to be written that same bill is constituted with the field to be written can not also participate in subsequent uplink operation, area
It includes quick that block chain network, which can return to the information of cochain failure to server to prompt field to be written involved in the bill,
Feel information, does not meet related request.The information of cochain failure can also be returned to enterprise UE terminal, enterprise customer's end by server
It is to be written involved in personal user's bill to prompt that the information of cochain failure can also be back to personal user's terminal by end
Entering field includes sensitive information, does not meet related request.In other embodiments, information of the block chain network in cochain failure
In carry instruction information, it includes sensitive information which, which is used to indicate specific field to be written,.When personal user is logical
Cross personal user's terminal get cochain failure information when, can be checked and be modified, and again to enterprise UE terminal
Send the new field to be written of write-in.
In specific implementation, some fields to be written comprising sensitive information are normal, in order to prevent this error detection
The problem of, as preferred embodiment, before S108, block chain network presets sensitive information white list；Then sentence
Whether the field to be written of breaking includes information in the sensitive information white list；If do not included, enter S108, it is no
Then, step corresponding to uplink operation is directly carried out.
It is to be understood that field to be written is magnanimity, if detected to each field, undoubtedly workload
Be it is huge, moreover, the sensitivity coefficient of not all field to be written be all it is high, therefore, in order to reduce workload, improve detection
Efficiency.Preferably embodiment, it is described judge whether the field to be written includes the sensitive information before also wrap
It includes:
Predefine the type of the field of screening；
Extract the target field to be written for meeting the type in the field to be written.
Judge whether field to be written includes the sensitive information it is to be understood that described specifically: judge the mesh
Mark whether field to be written includes the sensitive information.
Under normal conditions, the type includes but is not limited to: subscriber phone field, address name field, station address
Field, items list field, memo field, drawer's field, auditor's field.
It should be noted that the detection mentioned above for carrying out sensitive information to field to be written can directly carry out data
Splicing or jsonization or be formatted into other any forms (for example, binary system, hexadecimal etc.).
S109: when the field to be written does not include the sensitive information, block chain network is to the field to be written
Hash operation is carried out to obtain the Hash result.
S110: block chain network sends the Hash result to server.
It is to be understood that the data for needing to treat cochain carry out Hash operation before carrying out uplink operation to data
With digital signature processing, in this application, the data to cochain are exactly field to be written.
In a specific embodiment, the mode that block chain network carries out Hash operation to field to be written has following two
Kind:
The first: the field to be written detection of an each pair of bill of block chain network finishes, just at once in the bill
Information carries out Hash operation in order to carry out uplink operation.It is to be understood that the method is not necessarily to record testing result, so that right
The bill answered can rapid chain loading in the shortest time, can substantially shorten the time window of extraneous altered data in this way, increase
The difficulty and cost of data tampering.
Second: after block chain network has detected the field to be written of multiple bills, the ticket for having sensitive information will not included
Hash operation is carried out according to corresponding field to be written.It is to be understood that the method can effectively reduce detection sensitive information and
The switching times of Hash operation, but need to record the testing result of every bill.More specifically, block chain network can be set
The quantity of the bill detected every time after reaching this quantity, then carries out Hash operation, such as this quantity can be 10, i.e.,
Field to be written corresponding to 10 bills carries out the detection of sensitive information, after detect, by not comprising sensitive information to
Word is written and carries out Hash operation.
S111: server encrypts the Hash result to obtain the signed data according to the private key of itself.
S112: the signed data is sent to block chain network by server.
Server used private key when carrying out above-mentioned digital signature, can save in the server, work as service in this way
When device is needed using private key, directly transferred from local, naturally it is also possible to be to be saved by third party tube platform, work as server
When needing, third party tube platform is accessed.
In order to improve the safety of private key in server, server is in addition to needing to avoid that any protection processing will not be carried out
Private key is stored directly in local, it is also necessary to avoid to be stored in by conventionally known coding or the processed private key of encryption technology
It is local.In the embodiment of the present application, a set of customized private key protection mechanism can be created on server local, wherein this is made by oneself
Adopted private key protection mechanism includes but is not limited to customized private key encoding mechanism or customized private key encryption mechanism.Server is to private
Before key is saved, first with above-mentioned customized private key protection mechanism, respective handling is carried out to private key, then by treated
As a result it is stored in local.When subsequent server needs to call private key, can based on above-mentioned customized private key protection mechanism come
Restore private key.It is a kind of unknown private key protection machine for the external world since above-mentioned private key protection mechanism is customized
System, and for the external world, server use which kind of protection mechanism on earth carry out private key protection be also it is unknown, lead in this way
Above-mentioned private key protection scheme is crossed, the probability that private key is intercepted and captured by the external world can be effectively reduced, greatly improve local private key
Safety.
It is to be understood that in actual application, related technical personnel customized according to actual needs can meet
The private key protection mechanism of actual operation requirements.According to customized private key protection mechanism, server can be before saving private key
Corresponding protection processing first is carried out to private key.For example, in a specific embodiment, if private key can be divided by server
Dry is assigned with the segment of serial number, then modifies according to private key segment of the different segment alteration rulers to different serial numbers,
And the private key segment after all modifications is saved respectively to multiple and different storage locations of local periodically dynamic change.Example
Such as, private key is divided into 3 segments, wherein the corresponding segment alteration ruler of the 1st segment is by n-th of word of the 1st segment
Symbol and n-th of character reciprocal exchange, and the corresponding segment alteration ruler of the 2nd segment is to add one to the tail portion of the 2nd segment
Preset characters, the corresponding segment alteration ruler of the 3rd segment are that the specific character in the 3rd segment is all changed to another kind
Preset characters, after obtaining 3 modified private key segments according to above-mentioned segment alteration ruler, just they are saved respectively to
The corresponding 3 different storage locations of current storage location change cycle.It is to be understood that the later period when restoring private key, needs
The characteristics of first periodically being changed according to segment storage location, determine the storage location of different private key segments, then according to not
With segment serial number, corresponding different fragments alteration ruler restores the script information of different fragments, then carries out piece based on numeric order
Section splicing, can restore private key.
Since block chain network is made of multiple block chain nodes, each block chain node can be carried out sign test, because
This, signed data can be sent to any one block chain node by server.It should be noted that server is in order to reduce area
The case where workload of certain block chain link points is excessive in block chain network or is chronically at idle state, in the application, service
The signed data is sent to the process of block chain network by device, may include: server according to current each block chain node
Information on load and location information screen the block chain link point in the block chain network, obtain destination node, then will
The signed data is uploaded to the destination node.That is, the server in the present embodiment can voluntarily select block chain node
As the node for directly acquiring uplink data, also, server can be according to the information on load and location information of block chain node
Screen current suitable block chain node, server can select that current loads are smaller and geographical position in this way
Moderate block chain node is set as the direct node for receiving uplink data.In a specific embodiment, server may be used also
Hash operation result and corresponding signed data are uploaded to by using random in a manner of randomly selecting block chain network node
Block chain network node.In another embodiment specific implementation mode, server can also be by the way of poll, successively selected block
Chain node is as destination node.
S113: block chain network receives the signed data that the server returns, and utilizes the public key of the server
Sign test is carried out to the signed data, and stores the field to be written to block chain after sign test passes through.
Sign test process in the present embodiment is that signed data is decrypted and is verified using public key in fact.Usual situation
Under, the public key of server is stored in local, and the equipment where any one block chain node in block chain network is all preserved
The public key of server.On the one hand the Hash result being encrypted by private key is restored by public key, on the other hand compare the Kazakhstan restored
Whether uncommon result and the Hash result for being sent to server are consistent, to determine whether the Hash result is tampered.In the present embodiment,
After arbitrary node in block chain network gets the signed data of server transmission, first the signed data can be tested
Label after sign test passes through, just generate the block for preserving the Hash result in the signed data on this node, then broadcast
Other nodes into block chain network, other nodes are received and are verified, and can chase after above-mentioned block after being verified
It adds on block chain.
The embodiment of the present application judges that above-mentioned field to be written is after obtaining the field to be written for blank bill to be written
The no detection realized comprising sensitive information to above-mentioned field to be written will when above-mentioned field to be written does not include sensitive information
Above-mentioned field to be written carries out Hash operation, and after sign test passes through, obtained Hash result is stored on block chain.Thus
As it can be seen that the embodiment of the present application is that the corresponding field of electronic bill is stored by block chain network, so that after each field cochain,
Just can not be tampered, be effectively ensured monitoring party anaphase nucleus check tickets according to when authenticity.In addition, before cochain, also to upper

In the present embodiment, block chain network carries out the detection and Hash operation of sensitive information simultaneously, so that server is not required to
Signed data can be sent to block chain network by waiting the judging result of sensitive information, save interaction to a certain extent
Efficiency.Although in S415, obtaining server it is worth noting that, asynchronous process can be improved interactive efficiency
After signed data, if judging result is still not present by default delay time, it is directly written into data cochain.It can
See, the step in, may there are problems that one or more fields to be written include sensitive information and cochain.In order to overcome
This problem, the application also provide corresponding measure, i.e., carry out secondary detection to cochain field.It is to be understood that for
What a upper embodiment was mentioned carries out secondary detection to cochain field, is especially adapted for use in the feelings by asynchronous mode cochain
Condition.
During asynchronous, it is usually to take lesser inspection that cochain field, which includes that the probability of sensitive information is larger,
Survey period progress secondary detection.For example, the period can be 1 month, 2 months etc..Since detection cycle is shorter, so if right
Whole blocks are detected, then workload is huge, so only the upper detection of detection is all in each detection cycle in the present embodiment
Phase is to current newly generated block.
Fig. 6 is a kind of process of detection method that sensitive information is carried out to cochain field provided by the embodiments of the present application
Figure.As a preferred embodiment, whether the field of cochain for judging to store on the block chain in the present embodiment
It is specifically included comprising the sensitive information:
S501: current block height is obtained；Wherein, high using the corresponding block height of a upper detection cycle as starting
Degree；
S502: cochain field is obtained described in whole bills from the corresponding block of current block height；
S503: whether the judgement cochain field includes the sensitive information, if comprising the sensitive information, into
Enter S504, otherwise enters S505；
S504: the label corresponding bill of cochain field, and enter S505；
S505: judging whether to reach current maximum block height, if not up to, entering S506, if reached, into
Enter S507；
S506: current block height is increased into a height, and returns to S502；
S507: the current maximum block height of record returns to S505 using the starting altitude as next detection cycle.
By the above process it is found that the detection mode only detects a upper detection cycle to current produced new cochain
Field.It is to be understood that needing all to detect whole cochain fields, as long as there is a cochain field in S503
Include sensitive information, then corresponding result be exactly include the sensitive information, into S504, if all do not included, correspond to
Result be exactly not include sensitive information, into S505.
