Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.
As known from the background art, the data of the intelligent contract is stored in the blockchain in a plaintext manner, so that the data is easily directly stolen by lawbreakers, and the data is leaked. In addition, in many of the existing domestic blockchain landing applications based on Hyperledger Fabric, there are often cases where there is a need to link up data related to personal privacy, such as identification card numbers, user IDs, and the like. Although the blockchain can guarantee the tamper resistance of the data to a certain extent, people who illegally master the rights of the blockchain database can still check and obtain the plaintext privacy information and use the plaintext privacy information, so that the privacy data of the user is revealed.
In order to solve the problems, the invention provides a processing scheme of account book data, and the scheme provided by the invention can ensure that the data stored in a block chain is encrypted, thereby avoiding direct theft of the data by lawbreakers and avoiding data leakage.
The invention is operational with numerous general purpose or special purpose computing device environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet devices, multiprocessor devices, distributed computing environments that include any of the above devices or devices, and the like.
Referring to fig. 1, a method flowchart of a method for processing ledger data provided in an embodiment of the present invention is specifically described below:
s101, determining an intelligent contract to be processed.
The smart contracts to be processed may be smart contracts that have not been modified by the modification logic of the present invention.
Referring to fig. 2, a flowchart of a method for determining a smart contract to be processed according to an embodiment of the present invention is specifically described below:
s201, receiving a contract processing instruction.
The contract processing instruction may be an instruction sent by a developer, where the instruction includes, but is not limited to, authority information of the developer, personal information, boarding information of the contract, content of the contract to be processed, and the like.
Preferably, the rights information and contract level may be used by the system to determine the order of processing of the smart contracts.
S202, analyzing the contract processing instruction to obtain a contract identification code.
Preferably, the contract identification code may be a unique identification code of the intelligent contract, and the contract identification code may be composed of english letters with upper and lower cases, numbers, and special symbols. The contract identification code is the identification code of the intelligent contract.
S203, determining an intelligent contract corresponding to the contract identification code in a preset contract set, and determining the intelligent contract as an intelligent contract to be processed.
The contract set comprises a plurality of intelligent contracts, and the contract identification code traverses each intelligent contract in the contract set, so that the intelligent contract corresponding to the contract identification code can be obtained.
Each smart contract has a unique contract identification code.
According to the invention, the intelligent contracts to be processed can be accurately determined in the contract set by using the contract identification code, the appointed intelligent contracts are modified by the contract processing instructions sent by the staff, one contract processing instruction corresponds to one intelligent contract, and the follow-up tracing and the omission of the intelligent contracts are facilitated.
S102, adding processing function data into the intelligent contract to obtain the processing intelligent contract.
The determined intelligent contracts to be processed at least comprise a uplink function and a query function, and after the intelligent contracts to be processed are determined, the intelligent contracts are required to be modified, so that the processing intelligent contracts are obtained, and the processing intelligent contracts have the operations of encrypting, decrypting and the like on data which need to be uplink.
When processing function data is added to the smart contract, a pre-written modification script may be executed, and based on modification logic in the modification script, the processing function data may be added to the smart contract, and then a processed smart contract may be obtained.
Preferably, the system may need to process multiple intelligent contracts at the same time, if the number of intelligent contracts to be processed at a certain moment exceeds the processing capacity of the system, each intelligent contract may be ranked according to authority information and contract grade information in contract processing instructions corresponding to the intelligent contracts, then the intelligent contracts are processed according to the ranking order, for example, each intelligent contract is firstly ranked according to contract grade information, ranked according to the order of the contract grade from high to low, and when the contract grade is equal, the intelligent contracts are ranked according to the authority information, for example, the intelligent contracts are ranked according to the order of the authority from high to low.
Referring to fig. 3, a flowchart of a method for adding processing function data in an intelligent contract according to an embodiment of the present invention is specifically described below:
s301, inserting a data processing function in the intelligent contract, wherein the data processing function comprises an encryption function and a decryption function.
Preferably, the data processing function is inserted at the data end of the smart contract, in particular, the data processing function is inserted after the last line of data of the smart contract.
Preferably, the blockchain referred to in the present invention may be a Fabric blockchain network. To accommodate the characteristics of the Fabric blockchain network, the data processing functions include encryption functions including, but not limited to, PKCS5 packing for encryption and AesEncrypt functions for bit filling; decryption functions include, but are not limited to, PKCS5UnPadding for decryption and aeschrypt functions for bit filling.
Furthermore, the encryption function and the decryption function mentioned in the present invention can be adjusted and set according to the actual requirement and the blockchain of the actual application besides the functions mentioned in the above examples.
S302, inquiring application information of each function calling a preset writing function in the intelligent contract by using a preset inquiry instruction.
The query instruction may be an AWK instruction; the preset write function may be a PutState function.
There may be multiple places in the intelligent contract where the PutState function is called, and function application information of calling the PutState function everywhere in the intelligent contract is obtained, where the function application information includes, but is not limited to, specific location information of calling the PutState function by the intelligent contract, and information whether data processed when the PutState function is called is empty or not.
S303, for each function application information, based on the position information of the function application information, inserting calling information of an encryption function and calling information of a decryption function into the intelligent contract.
The function application information includes location information of the write function in the smart contract when the write function is called, the location information includes contents such as a start location and an end location of a code for calling the write function, and the function application information includes information whether or not data processed when the write function is called is empty.
When inserting the call information of the encryption function in the smart contract, the call information on the encryption function may be inserted above the write function call, specifically, for example, the call of AesEncrypt is added above the PutState function call.
In inserting call information for a decryption function in the smart contract, call information for the decryption function may be inserted below the write function call, specifically, for example, a call of AesDecrypt is added below the PutState function call. Further, the decryption function needs to determine whether the data to be decrypted is empty when decrypting, and if so, decryption failure may be caused, because, in order to improve the success rate of decryption, when the decryption function is reused later, whether the data to be decrypted is empty may be determined first, if so, the decryption function may not be used for decrypting, and if not, the decryption function may be used for decrypting.
Further, after processing function data is added to the intelligent contract, a processing intelligent contract is obtained. After the processing intelligent contract is obtained, the processing intelligent contract can be installed and instantiated, and further, after the processing intelligent contract is obtained, the corresponding intelligent contract can be deleted.
After instantiating the process intelligence contract, all functions of the process intelligence contract can be called and the condition of the uplink can be tested so as to ensure that the subsequent process intelligence contract can be normally applied.
Preferably, when the applied blockchain is a Fabric blockchain network, the couchDB or the level db of Fabric can be used to compare whether the data on the chain is ciphertext storage, so that the data on the chain on the intelligent contract can be further ensured to be encrypted data.
Further, the processing function data is added in the intelligent contract, so that the contract realization logic of the intelligent contract is not affected, the modification is performed under the condition that the original data of the intelligent contract is unchanged, and therefore the intelligent contract which can normally realize the contract logic and encrypt the uplink data can be obtained.
And S103, executing the processing intelligent contract when a transaction instruction is received, generating encrypted account book data by using an encryption function in the processing function data, and uploading the account book data in a preset blockchain.
The transaction instruction is an instruction sent by a user, and the transaction instruction comprises a contract identification code of the processing intelligent contract, data supporting the execution of the processing intelligent contract, personal information of the user and the like.
When the processing intelligent contract is executed, transaction logic or contract logic corresponding to the contract can be realized, so that account book data can be obtained, the account book data at the moment is plaintext data, then encryption processing can be carried out on the account book data by using an encryption function in the processing intelligent contract, preferably, the encryption processing involves contents such as bit filling and encryption, so that the encrypted account book data corresponding to the transaction instruction can be obtained, and then the encrypted account book data is uplink in a blockchain.
Further, after the encrypted account book data is uploaded, prompt information of successful account book data uploading can be generated, and the prompt information is fed back to the user corresponding to the transaction instruction, so that the user can know that the requested transaction is successful.
It should be noted that, the invention can also query the data on the blockchain, and the specific query process is as follows: receiving a data query request, and determining account data corresponding to the data query request in a blockchain as target data; and decrypting the account data by using a decryption function in the data processing function to obtain decrypted data, and displaying the decrypted data to a user corresponding to the data query request.
The data query request may be a request sent by a user, where the data query request includes a data identifier of data to be queried, and then the corresponding data is searched through the data identifier, where it should be noted that the data identifier is a unique data identifier, and the data identifier may be used to determine the target data in the blockchain.
Preferably, after the target data is determined, whether the target data is empty or not may be judged first, if the target data is empty, decryption is not required, and if the target data is not empty, decryption may be performed using the decrypted data in the processing smart contract, so that the user may obtain the decrypted data.
In the method provided by the embodiment of the invention, an intelligent contract to be processed is determined, and processing function data is added in the intelligent contract to obtain a processed intelligent contract; executing the processing intelligent contract when a transaction instruction is received, generating encrypted account book data corresponding to the transaction instruction by using an encryption function in the processing function data, and uploading the account book data in a preset blockchain; by modifying the intelligent contract, the processing intelligent contract is obtained, so that encrypted account book data can be obtained after the processing intelligent contract is executed, and then the account book data is uplink, so that the data of the blockchain are ensured to be ciphertext data, the direct theft of the data in the blockchain by illegal persons can be effectively avoided, and the leakage of private data of a user is avoided.
The invention provides a scheme for explaining the application scene, which is specifically as follows:
and 1, constructing a plurality of accounting nodes, and constructing a Fabric block chain network by using the accounting nodes.
And 2, creating a channel of the blockchain network.
And step 3, writing an intelligent contract, wherein the intelligent contract at least comprises a uplink and inquires two functions.
Step 4, writing a script which can be used for modifying the intelligent contract, and modifying logic of the intelligent contract after executing the script is as follows:
step 1) reading an externally input intelligent contract file path and an AES key randomly generated by the outside, wherein other symmetrical encryption algorithms can be selected besides the algorithm exemplified by the invention;
step 2) adding PKCS5Padding and AesEncrypt functions for encryption and bit filling and PKCS5Unpadding and AesDecrypt functions for decryption in sequence at the bottommost part of the intelligent contract;
step 3) reading the intelligent contract, and searching all places calling the PutState function in the intelligent contract through an AWK instruction, wherein the call of AesEncrypt is added above the PutState function call;
step 4) find the places of all PutState through AWK instruction, and add the decryption function AesDecrypt below it. The point of difference from AesEncrypt is that decryption fails because the queried data may be empty. Therefore, whether the queried data is empty or not needs to be judged outside the decryption function;
and 5) re-outputting the modified intelligent contract file to a new file, and deleting the original file.
Further, after the intelligent contract is modified, a new intelligent contract is obtained, then the original intelligent contract can be deleted, the data redundancy is reduced, and the utilization rate of the memory is improved.
And 5, installing and instantiating the modified intelligent contract.
And step 6, calling all intelligent contract functions and testing the uplink condition.
And 7, comparing with a couchDB or a level DB of the fabric to see whether the data on the chain is ciphertext storage.
By using the method provided by the invention, the intelligent contract can be modified based on an external program, the on-chain data can be ensured to be stored in a ciphertext under the condition that the original logic of the intelligent contract is not affected, and the method can be applied to any intelligent contract written based on the Go language and used for Fabric. By the method provided by the invention, the intelligent contract can have the functions of encrypting the uplink data and decrypting the queried on-link data in a very short time, so that an illegal user cannot directly browse and utilize the privacy data related to the user on the link, and the privacy data of the user is ensured to a greater extent.
