Above-mentioned purpose realizes by following technical scheme:

A kind of method of bank bill online authorisation and off line trading, its composition comprises authorizes on the line and off-line transaction two parts composition, it is characterized in that: authorizing on the line is to be carried out in the transaction disposal environment that the bank of deposit of institute provides by the payer, off-line transaction then is to be carried out in the transaction disposal environment that paying bank or third party provide by the payee, one transaction is divided into two relatively independent processes, and connect by the bill that carries believable effect, reach safe real-time payment purpose, its hardware is formed and is comprised:

One Trading Authorization terminal, the payer owns, be meant can with paying bank's equipment that accepting server carries out information interaction of concluding the business, main PC and the mobile phone that can surf the Net of finger, it links to each other with the transaction accepting server of paying bank by internet or wireless network;

Terminal is submitted in one transaction to, the payee all, be meant can with paying bank's equipment that accepting server or the third party service organization carry out information interaction of concluding the business, mainly PC, mobile phone or the landline telephone that can surf the Net of finger;

One transaction accepting server, paying bank owns, the mutual environment that is used to the payer Trading Authorization to be provided and to provide a transaction to accept for the payee, it is made up of one or more WEB server and voice server, submits to terminal to link to each other by internet, wireless network or public telephone network with Trading Authorization terminal and transaction;

One identity certificate server, paying bank owns, and is used to verify the legitimacy of receipts, payer's identity;

One data-storing server, paying bank all, be used to store conclude the business and carry out information-related data with payer's Trading Authorization and payee;

One calculation server, paying bank owns, and is used to generate, verifies and examines from receipts, payer import for information about;

One security protection system, the payer owns, and is used for the protection transaction and normally carries out and safety, and it is made up of equipment such as fire wall, routers;

Described all continuous by LAN (Local Area Network) or special line by all equipment of paying bank;

The method that realizes between each system is as follows:

Authorize on the line: the payer lands the WEB server by authorization terminal, after passing through the safety certification of authentication server, autonomous option dealing authorization message item on the Trading Authorization page of the unified standard that the WEB server provides, to trading range, feature is carried out autonomous Trading Authorization, form and authorize element information, carry out cryptographic calculation or signature by calculation server or third party to comprising described mandate element information, generate one group of payment cipher that is associated and authorize serial number, and will this time authorize relevant Transaction Information to be stored in the data-storing server with the payer, the online Trading Authorization terminal that passes to of information with clients such as described payment cipher and mandate serial number need is kept by payer's storage or record;

Off-line transaction: the payee submits to terminal to submit request to paying bank or third party service organization's initiation transaction by transaction, the relevant mandate element information item that is provided according to the transaction accepting server of paying bank, form prompting payee with interaction finishes input, after correct input such as the described information that requires the payee to import about mandate element information item and payment cipher etc. finishes, calculation server is according to the resulting trade identity audit of the mandate element information of transaction being carried out strictness from payee's transaction data request and payer, whether satisfy the condition of payer institute authority to pay fully with the Transaction Information of checking payee submission, by after, calculation server will send the corresponding service processing instruction according to payer's mandate, finish accordingly by the comprehensive business system of paying bank and to transfer accounts, circle such as deposits at operation, and related data in the renewal data-storing server, with the online transaction submission terminal that feeds back to of result, pass to the payee, and print or store corresponding bank and return document, closing the transaction.

This technical scheme has following beneficial effect:

1, convenience: the characteristics of maximum of the present invention are exactly simple to operate and convenient, and the convenience that it promptly has a Web bank has remedied the deficiency of Web bank again, for the client provides simple, convenient, quick, a safe trade mode.

2, low cost: the present invention does not invest the requirement of specialized equipment for the bank settlement people, the most simply as long as the payer has a computer, the payee has a phone can finish transaction safely, be suitable for extensive popularizing, this can save huge human cost and bill management cost for financial company, it will help financial company to realize no cash transaction all taken to carry out on the net and without any obstacle, comprise transacting targeted and the uncertain transaction of the amount of money, and this is the development in future direction.

3, security: owing to used safety technique such as digital authenticating, the client has safety guarantee to the mandate of transaction, also has non-repudiation, therefore, it can refuse the risk that all outside swindles, inner swindle and maloperation bring for financial company on bill business, solved the transaction risk problem of financial company.

In concrete enforcement of the present invention, can take following mode to improve service quality or system performance:

1,, when carrying out with paying bank's data interactive, payer and payee all should be subjected to data security protecting for guaranteeing the safety of Transaction Information.

2, in order to guarantee transaction security, suggestion is all finished by the third party links such as the generation of 16-20 position payment cipher and veritifications, and financial company can break away from responsibility better when dispute occurring like this.

Simultaneously, when using non-payer's key to generate payment cipher, selected information is except will using the selected mandate element information of payer, also to will this time authorize relevant with the payer, and can prove that the payer participates in this information of authorizing and includes in into, can comprise the biological information when landing, dynamic password, be used to verify undeniable direct informations of client such as note validating password that bill is true and false or the undeniable information of obtaining indirectly of payer or the data of approving its exclusive property with the payer, the IP that comprises the payer, MAC, direct information or indirect information such as network adapter address from hardware from hardware, guarantee that the payment cipher that is produced is the result that the payer authorizes, and has non-repudiation.

3, when whether the validation of payment password is correct, the payment cipher of payee's input is to check with the payment cipher of once preserving with storage mode, or check with the payment cipher that the information of importing according to the payee regenerates, still use and generate the corresponding PKI of payment cipher it is verified from there not being too many difference in essence, because data are to be stored in bank, as safe as a house, but more be in conformity with law and explain and be it to be verified easily with corresponding PKI, during checking, everyly import the corresponding information that the mandate element information of acquisition all will replace the payer once to import, so both can more safely confirm the legitimacy of concluding the business from the payee.

4, for guaranteeing transaction security, the payer should be provided with bill and access to your password, when authorizing, import numeral or bearer's ID (identity number) card No. of a 6-8 figure place by the payer, be that easy note plays safe effect again, need the bearer to provide during payment, to finish the correctness of correct verification payment cipher, lose also at bill like this and can not bring economic loss to enterprise, certainly, also can be with the note validating password as the accessing to your password of bill, but shortcoming is to be not easy to remember and take care of.

Simultaneously, if bank's validation of payment password is to take to regenerate or use public key verifications according to the information of payee's input, this bill accesses to your password so, information such as pay code, cheque number had better not authorize element information and store along with other, breaks away from responsibility to increase security and to help bank.

5, the payer takes the internet to log in the WEB server to the mode of Trading Authorization optimum exactly, feasible technically as for the mode of taking SMS or phone mandate, but operation and dirigibility are restricted, can't reflect the Autonomous Control of payer exactly to authorizing, when accepting the information that the payee imports also is like this, take the mode of editing short message to submit the relevant element information item and inadvisable of authorizing to, therefore, suggestion financial company greatly develops the Internet model mandate.

6, authorize serial number to manage for convenience and raise the efficiency and be provided with, it has irreplaceable effect, because each payer is inequality to Trading Authorization, the Trading Authorization that has may be very complicated and careful, authorize the serial number mandate key element that each is different to associate by one, promptly being convenient to management has also increased safety, and for long-term goal, suggestion authorizes serial number to work out according to following arrangement:

Country code (3)+bank's row number (5)+days (4)+flowing water serial number (5)+identifying code (3), totally 20.

When the payee imports the mandate serial number, for preventing malicious attack, accepting server should be imported number of times to the payee and be limited, and to watch out for the terminal that those attempt constantly to visit accepting server, if submit this transaction to, submit to each time and point out payee's input page identifying code by PC.

7, for guaranteeing transaction security, paying bank should notify the related personnel with SMS when the payer authorizes success, notify different clients according to the different mandate amount of money, authorizing the amount of money and client's phone number should be that the client is reserved in bank, to prevent when the inside crime takes place, in time notifying the relevant personnel.

8, paying bank also should require the client that the amount of money of online mandate is done a restriction, prevent that a huge sum of money is stolen, simultaneously, paying bank also should take time-delay to come into force to a huge sum of money mandate, be the client to a huge sum of money mandate after, should delay a bit of time could arm's length transaction.Paying bank should provide counterbalanced accounts for transaction, services such as deletion.

9, described circle is deposited the fund of temporarily freezing certain number in payer's account that is meant, to guarantee the safety of transaction, strengthen payee's confidence, the present invention does not advocate that direct circle is deposited in payer account, but circle can be existed fund unification in payer's account transfer in the holding account or specially in the family manager come, can save huge interest expense for paying bank every year like this.

Simultaneously, when the payer takes formerly to enclose when depositing, paying bank should be printed on the corresponding bill for the payer provides a sign that has security feature accordingly, to strengthen payee's confidence.

10, the various servers of paying bank of the present invention, in fact be exactly the existing bank system of web of paying bank, paying bank only needs on the net to do an empowerment management page in the banking system and can finish, described voice server also is the telephone bank system of each tame bank, increase a new function, on hardware,, can subdue the cost of enterprise without any special requirement.

11, the client during to the banker's buying rate bill, bank should be mapped the account of note number and enterprise, and be the note validating password that the client generates a correspondence at each bill preferably by bank, and with this incidence relation and data storage in the data-storing server, also can allow the client generate note validating password or status identifying code voluntarily, or on bill, write magnetic by paying bank, less radio-frequency etc., purpose is the legitimacy of verifying and examining bill self and user effectively, carry out Trading Authorization and payee the payer and conclude the business and be used for verifying the legitimacy of transaction when submitting to, increase transaction security with the dual channel road.

12, the audit of described trade identity is can be according to the design proposal of financial institution different and adjusted, can be embodied in first comparison, also can compare in real time, comparison formerly, be exactly when the payee does not also import about mandate element information item, the transaction accepting server is examined information such as the transaction count of this transaction, the zones of concluding the business in real time according to the information from the payee earlier, the then continuation that satisfies condition, otherwise remind the payee that transaction can't continue; Comparison in real time, exactly the information of payee's input is examined in real time, compare in real time with the information of payee's input and from the data in the storage server, but this real-time audit is higher to the performance requirement of system, the time of single transaction can prolong, and can be subjected to the loco when formerly comparing and collecting account deviation do not occur or needs comparison again in same zone.

13, payee of the present invention is only limited to the seller, and it also can be the teller of bank, and bank cashier also can assist to finish real-time deal between the both parties and need not bear any transaction risk.
