Background
The bank letter refers to the process that the registered accountant directly obtains written responses from the bank as audit evidence, and is an audit program commonly used by the registered accountant for executing audit work. In recent years, in auditing practice, registered accountants have encountered many obstacles and difficulties in implementing a bank letter procedure, resulting in many cases in failure to obtain sufficient and appropriate audit evidence through the procedure.
The bank letter can not be handled reasonably at the bank account opening bank. The registered accountant typically goes to the issuer and is coordinated by the customer manager of the audited organization. This process receives the interference in the aspect of the customer easily, and the independence is low, has the risk that customer and bank employee collude and make the fake, causes register accountant can't pass letter verification bank account information's authenticity, accuracy and integrality, influences the audit effect, also brings adverse effect to the public credit ability and the reputation of bank simultaneously.
The posters have low reply rate, and the bank requirements are different, so that the auditing efficiency is low. The result of letter implementation by post is not ideal, and the rate of reply is very low because of serious delay or no reply in handling the letter in the bank. The registered accountants usually go to the bank directly for on-site confirmation, thereby spending a lot of manpower and financial resources and greatly increasing the auditing cost.
The bank uses stamps without legal effect, resulting in the loss of proof of the letter. At present, there is no clear regulation on the use of seals for the reply of bank's inquiry. It is difficult for the registered accountant to actually determine whether the signature and seal in the bank reply have been properly authorized for approval. Some banks use counter acceptance badges without legal effectiveness, so that the proof of the inquiry letter reply is lost, and the audit risk is increased.
Some banks send the letter back to the audited unit, which affects the effect and efficiency of letter. Some banks do not deal with the purpose of the inquiry letter and do not communicate with the registered accountants in time, the inquiry letter of the bank is sent back to the audited unit, and then the audited unit hands over the registered accountant, thereby greatly influencing the reliability of the letter.
The participants bear unnecessary risk and cost. The bank provides letter window service in each branch bank and business network, and the operation cost is high. The accountant affairs office makes and mails the bank letter, urges the bank to return letter, sends the person to complete the letter operation on the spot when the letter can not be posted, collects and verifies the return letter and the like, and has high working cost and low efficiency. Moreover, the inherent audit risk of the letter service is higher, the conditions of forging signatures and letters exist, and an auditor is often difficult to distinguish.

(2) The auditor receives the inquiry data packet of the auditor, the inquiry data packet is imported from the client, when the U-KEY is inserted and connected with the public network, the private KEY of the mechanism can be used for signing the inquiry data which passes the audit, the public KEY of the enterprise to be audited is used for encryption, and then the inquiry data is uploaded to the alliance chain.
In special cases, an auditor and an auditor can work on the same PC, and the exporting, sending, receiving and importing processes can be omitted.
And S3, obtaining the verification result of the authorized party to the encryption inquiry information and authorizing the verified encryption inquiry information.
The authorized party is the enterprise party. The role of the enterprise personnel only needs to be auditors. The auditor inserts U-KEY in the note system client PC and connects with the public network, downloads the encrypted inquiry data of the firm from the chain, after checking, signs with the enterprise private KEY, encrypts with the public KEY of the bank of the account opening, and uploads to the chain.
Under special conditions, an enterprise auditor can complete the business by plugging the client of a field auditor with the U-KEY of the auditor.
And S4, acquiring a letter result generated by the reply formula according to the inquiry information, and encrypting and uploading the letter result to the block chain.
The compound prescription is the bank. There are two types of roles for banking personnel: (1) a manager: the bank note information checking and rechecking method refers to all personnel participating in business work such as letter information checking and rechecking in a bank. (2) The operator: the holding bank U-KEY uses the PC of the client of the installation letter system to connect with the public network to work, and acts as an intermediary inside and outside the bank, downloads the inquiry letter from the chain and transmits the final result to the chain.
Letter receiving process: the operator downloads the encrypted inquiry information from the chain and decrypts the inquiry information by the private key of the local line. The inquiry function information is packaged and exported, or the document is output according to a standard format. And transmitting the data packet, the electronic document or the paper document (which is specifically adopted and is determined according to the internal business process of the bank) to the related operator.

According to the internal regulation and the informatization degree of the bank, internal business processes can be completed through automatic structured data transfer, automatic unstructured data transfer or manual transfer modes, and a final letter result is generated. The relevant sponsor transmits the letter results to the operator.
And (3) a reply process: the operator receives the letter result of the sponsor and inputs (importing, scanning and other modes) the letter result at the letter system client. And after the verification is correct, the private key of the bank is used for signing, the public key of the consultation institution is used for encrypting, and then the public key is uploaded to the chain.
The letter system bill client is physically isolated from the bank internal system. When a multi-user application system (such as a bank internal flow system) is used, the interaction of the systems of the two parties is completed by using a bank front-end processor according to the safety specification requirement of the bank.
And S5, returning the encrypted result to the requester from the blockchain and decrypting the encrypted result according to the decryption instruction of the requester.
And (3) a transaction institute letter receiving process: (1) the auditor PC is connected with the public network by inserting the U-KEY, downloads the encrypted bank reply data from the chain, decrypts the encrypted bank reply data by using a private KEY of the auditor PC, packs and exports the reply data, and sends the reply data to an auditor.
