In one embodiment, electronic bill data include data relevant to bill issue behavior.The side's of making out an invoice block chain Node can receive the request of making out an invoice for request end transmission of making out an invoice, and request of making out an invoice carries billing information, and billing information includes the side of making out an invoice Mark, electronic bill mark, recipient's mark and the amount of the instrument；The side's of making out an invoice block chain node is raw after receiving and making out an invoice request At electronic bill inquiry code corresponding with billing information, electronic bill is generated according to billing information and electronic bill inquiry code, and Data block is written into electronic bill and current bill state.Therefore, the electronic bill data that bill issue behavior is related to The time is issued including the side's of making out an invoice mark, electronic bill mark, recipient's mark, the amount of the instrument, bill state and bill, etc. Deng.

In one embodiment, electronic bill data include data relevant to bill reimbursement behavior.Submitting an expense account method, apparatus can The reimbursement document that reimbursement request end is sent is received, reimbursement document includes electronic bill inquiry code, and reimbursement method, apparatus can be to area Reimbursement side's block chain node checks electronic bill corresponding with electronic bill inquiry code in block chain network, according to the electricity found Sub- bill checks reimbursement document, and after verification passes through, electronic bill is transferred to reimbursement side according to reimbursement document, and trigger electricity The update of the bill state of sub- bill uploads the bill state of update so that the bill for saving the electronic bill saves server To corresponding block chain node.Therefore, the electronic bill data that bill reimbursement behavior is related to include the bill state updated, electricity The time, etc. that the time of sub- bill transfer and bill state update.

In one embodiment, electronic bill data include declaring dutiable goods the relevant data of behavior to bill.Declaring dutiable goods request end can To initiate request of declaring dutiable goods to the side's of declaring dutiable goods block chain node, request of declaring dutiable goods carries the side's of declaring dutiable goods mark, and the side's of declaring dutiable goods block chain node is true Determine the electronic bill corresponding with the side's of declaring dutiable goods mark stored in data block, and inquires and identify associated ginseng of declaring dutiable goods with the side of declaring dutiable goods Number, so that it may declare dutiable goods the amount of tax to be paid according to the electronic bill that finds and parametric statistics of declaring dutiable goods, the side of declaring dutiable goods can also be identified and update Block chain node of state of the declaring dutiable goods corresponding record into block chain network, and by electronic bill and declared dutiable goods state corresponding record Block chain node into block chain network.Therefore, the electronic bill data that the bill behavior of declaring dutiable goods is related to include the report updated Tax state, the amount of tax to be paid of declaring dutiable goods, the side's of declaring dutiable goods mark be corresponding to declare dutiable goods state and time that electronic bill be used to declare dutiable goods, etc..

S204 determines group's mark corresponding with electronic bill data.

Wherein, group is collective relevant to the circulation process of electronic bill, including enterprise and institution etc..Group's mark It is the mark for unique identification in network communications as group's identity of one side of communication.Group's mark can be including number The character string of the characters such as word, letter or symbol.When a group needs to lead ticket, make out an invoice, submit an expense account or declare dutiable goods, group can lead to It crosses computer equipment and identifies the corresponding corresponding request of block chain node initiation into block chain network according to group.It is, Group can be any one in the side of making out an invoice, bill preservation side, reimbursement side and the side of declaring dutiable goods.

Specifically, as above, electronic bill data are synchronized to bill management by the block chain node for initiating common recognition certification and take Business device, therefore, electronic bill management server can be determining and electric according to the identity of the block chain node of synchronous electronic bill data The corresponding group's mark of sub- bill data, and identified according to group and store electronic bill data classification.For example, right by the side of making out an invoice The electronic bill data that the block chain node of making out an invoice answered is synchronized to electronic bill management server can be corresponding with the side's of making out an invoice mark Storage saves the corresponding bill of server by bill and saves the electronic ticket that block chain link point is synchronized to electronic bill management server It corresponding with preservation side's mark can be stored according to data, electronic bill is synchronized to by the corresponding bill reimbursement block chain node in reimbursement side The electronic bill data of management server can it is corresponding with reimbursement side's mark storage, etc..

In one embodiment, group's mark is distributed by electronic bill management server.Group need record with When the relevant data of electronic bill or processing process relevant to electronic bill, it can be taken by community device to electronic bill management Business device initiates registration request, and the identity information of the group can be carried in registration request, and identity information such as can be the group Business license information or taxpayer's information etc., after electronic bill management server receives registration request, so that it may according to note The identity information carried in volume request or the existing qualification progress with the associated taxpayer's information of the identity information to the group Audit, after the approval, so that it may generate group's mark corresponding with the group, and group mark is back to group and is set It is standby.

S206 inquires the private key that distribution cipher key pair is identified by group.

Wherein, key pair is the electricity when group sends registration request to electronic bill management server by community device Sub- bill management server is the public private key pair that group generates.Public key (Public Key) and private key in public private key pair (Private Key) is the key pair obtained by algorithm, and public key is key disclosed in cipher key pair, and private key is then non-public affairs The key opened.Electronic bill management server can generate number card according to the identity information of public key and enterprise in public private key pair The public private key pair can be also sent to community device and block chain corresponding with community device by book, electronic bill management server Node.In this way, community device can sign to data according to private key, area when sending data into block chain node Block chain node can carry out sign test to data by public key, to confirm that the data received are point after receiving the data of signature Group's transmission of the public private key pair is matched.When block chain node needs electronic bill data block is written, basis is needed Public key in the public private key pair of distribution is written again after encrypting to electronic bill data.

Specifically, the public and private key for the mark distribution of each group is stored in the database of electronic bill management server It is right, for by group mark classification storage electronic bill data, can electronic bill data have been determined group mark after, Exactly the electronic bill data are to be generated by which side and be written in data block, so that it may be inquired in local database The private key of corresponding cipher key pair is identified with the group.

S208 decrypts electronic bill data according to private key and obtains the electronic bill data of plaintext.

Specifically, when the electronic bill is generated, use is generated by the corresponding side's of the making out an invoice block chain node in the side of making out an invoice at random In the bill key encrypted to electronic bill data.The bill key can be a kind of symmetric key, with the symmetric key Electronic bill data are encrypted, after the electronic bill encrypted, the electronic bill of the bill key pair encryption can be passed through It is decrypted, obtains the electronic bill data of plaintext.

When in the side of making out an invoice, data block is written in electronic bill data by block chain node, need to mark by the group for the side of making out an invoice The public key for knowing corresponding cipher key pair encrypt and encrypt by bill key pair electronic bill data to bill key, After the electronic bill data encrypted in data block are synchronized to local by electronic bill management server, so that it may according to key The bill key of the private key decryption encryption of centering obtains bill key, then the electronic bill data by the decryption encryption of bill key Obtain the electronic bill data of plaintext.

Similarly, block chain link point is saved in bill or reimbursement side's block chain node needs electronic bill data number is written When according to block, need the public key for identifying corresponding cipher key pair by the group of the group of preservation side mark or reimbursement side to writing The electronic bill data entered could be written after being encrypted, and such electronic bill management server is getting synchronous electronic ticket When according to data, so that it may which the private key of inquiry preservation side or the corresponding cipher key pair in reimbursement side is decrypted, and obtains the electronics of plaintext Bill data.

S210, according to the electronic bill data of plaintext, the electricity that based on block chain network is carried out corresponding to group's mark Sub- bill circulation behavior is analyzed.

Wherein, electronic bill circulation behavior includes that the bill of electronic bill claims behavior, bill issue behavior, bill preservation Behavior, bill reimbursement behavior and bill are declared dutiable goods behavior etc..Electronic bill management server can be used for flowing through electronic bill Journey is managed, and according to synchronous electronic bill data, collects total data of electronic bill during circulation.

It specifically, can after the electronic bill of plaintext is stored in local database by electronic bill management server It is analyzed with the electronic bill data corresponding to each group mark, obtains each group and be based on block chain network about electricity The statistical result data of the carried out circulation behavior of sub- bill.Electricity can also be analyzed from macroscopic perspective using multiple groups as object The circulation process of sub- bill data, measures the management level of electronic bill.
