Specifically, the audited node (i.e. the node where the audited party is located) sends to the auditing node first ciphertext data relating to first monetary data (i.e. financial data) of the target transaction record; an auditing node (a node where an audited party is located) makes an inquiry letter based on the first ciphertext data, and sends the inquiry letter to at least one inquired node (namely, a node where the inquired party is located) related to the target transaction record; the inquired node sends a reply to the audit node, wherein the reply comprises second ciphertext data of second amount data related to the target transaction record; and the auditing node verifies whether the transaction record is real or not based on the first ciphertext data and the second ciphertext data. In one embodiment, the auditing node verifies whether the transaction record is authentic based on the first ciphertext data and the second ciphertext data includes the auditing node sending the first ciphertext data and the second ciphertext data to the privacy computing node, so that the privacy computing node invokes a homomorphic addition algorithm through an intelligent contract to verify whether the sum of second amount data of all nodes to be authenticated is less than or equal to the first amount data, wherein if the sum of the second amount data of all nodes to be authenticated is less than or equal to the first amount data, the transaction record is determined to be authentic. The first ciphertext data and the second ciphertext data can be obtained by performing privacy calculation in any node mode of homomorphic encryption, zero knowledge proof, multi-node safe calculation and a trusted execution environment.

In this embodiment, the step of obtaining the first ciphertext data by the audited node may be sending a privacy calculation request to the audited node, the idle first privacy calculation node receives the privacy calculation request sent by the audited node, creates a privacy calculation task, uploads the process of creating the privacy calculation task to the block chain, the audited node verifies the data access right of the first privacy calculation node through the block chain, after the verification is passed, the block chain is further used for verifying the sub-model of the first privacy calculation node for privacy calculation, after the sub-model is verified, the first privacy calculation node may obtain the first amount data of the audited node, perform privacy calculation on the first amount data to obtain the first ciphertext data, and send the first ciphertext data to the audited node. And the audited node sends the received first ciphertext data to the auditing node through the block chain. The step of obtaining the second ciphertext data by the node to be authenticated may be performed in the same manner as the above-mentioned step of obtaining the first ciphertext data by the node to be authenticated, which is not described herein again. Wherein the first and second privacy computing nodes may not be nodes in a blockchain.

And the letter collection unit is used for responding to the collection operation of an auditor and collecting the letter based on the return letter subjected to the first signature and the second signature. After receiving the reply of the first signature and the second signature, the auditing party indicates that the auditing process is finished, can collect all the letters (including the first letter, the second letter, the reply and the like) under the auditing party according to the auditing project, and sets the auditing project to be in a finished state after the collection is finished. During collection, the system checks that all letters are in the finished state; if the letter is not completed partially and is determined by auditors, the inquiry can be terminated.

The letter service platform may further include: the verification module is used for acquiring the letter to be verified, calculating a hash value to be verified of the letter to be verified, and comparing the hash value to be verified with at least one letter hash value of the first letter, the second letter, the third letter and the reply letter to judge whether the letter to be verified is tampered or not and/or judge the letter stage to which the letter to be verified belongs; wherein the hash value of the letter is stored in the blockchain.

In this embodiment, in the interaction process between the audit node and the audited node and between the audit node and the audited node, the hash operation may be performed on the first inquiry letter, the second inquiry letter, the third inquiry letter, and the reply letter to obtain a first hash value, a second hash value, a third hash value, and a fourth hash value, and the first hash value, the second hash value, the third hash value, and the fourth hash value may be stored in the blockchain.

In an embodiment, if a user wants to verify whether an inquiry letter stored locally is tampered, the user may obtain the letter to be verified, perform hash operation on the letter to be verified to obtain a hash value to be verified, compare the hash value to be verified with at least one of the first hash value, the second hash value, the third hash value, and the fourth hash value, determine whether the letter to be verified is tampered, and further determine a letter stage to which the letter to be verified belongs. Wherein the letter phase comprises: making and authorizing a letter, signing a signature of an audited node, signing a signature of the audited node and returning a letter, wherein a file corresponding to the making and authorizing stage is a first certificate inquiry letter; a file corresponding to the signed stage of the audited node is a third inquiry letter; a file corresponding to the signing stage of the audit node is a second inquiry letter; the reply stage is the stage after the node being authenticated is signed, and the corresponding file is a reply. For example, if the hash value to be verified obtained by performing the hash operation on the function to be verified is the same as the second hash value, it can be known that the function to be verified is in the stage of signing the signature of the audit node, and the function to be verified is not tampered.

The step of obtaining the to-be-verified letter may be executed by at least one of the auditing node, the audited node, and the inquired node, may also be executed by other verifying nodes, and may also be executed by a server corresponding to the blockchain, which is not limited herein.
