Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention is an information authentication method, which can be implemented based on a program module running on an electronic device of a computer, and increases data tampering difficulty and improves effectiveness of information authentication by setting a data processing policy and introducing a plurality of hash value verification means, as shown in fig. 1.
Fig. 1 shows a flow of an information authentication method according to a first embodiment of the present invention. As shown in fig. 1, the information authentication method specifically includes the steps of:
Specifically, in the process of transaction, it is necessary to collect relevant document materials, identity information, service information, and the like as original information according to actual service requirements to store (i.e., store a certificate), and subsequently, if the service needs to be operated, it may be necessary to upload corresponding document information again to perform authentication, so that the uploaded document information is the information to be authenticated.
In this embodiment, the processing policies may be configured in advance based on actual service requirements and stored, and each processing policy may specifically include a service level, a level determination criterion, and a processing manner, where the processing manner may specifically include a type of a packed file and a file packing manner.
In the process of determining the processing policy corresponding to the information to be authenticated, the corresponding processing policy needs to be obtained from a processing policy file stored in advance based on the related service information contained in the information to be authenticated.
And 102, extracting at least one data file from the information to be authenticated based on the processing strategy and packaging the data file.
After the processing policy corresponding to the information to be authenticated is determined in step 101, the information to be authenticated can be processed according to the specific content in the processing policy.
Specifically, the method may include extracting a file to be packaged from the information to be authenticated based on a corresponding processing manner in the processing policy, and packaging the file to obtain a packaged file.
And 103, calculating the packed data file to obtain the hash value to be authenticated of the information to be authenticated.
The hash value for the packed file is computed based on a hash function, such as the MD5Message Digest Algorithm (MD5Message-Digest Algorithm) or SHA-1, SHA-2, SHA-256, SHA-512, or the like.
All hash functions have the following basic characteristics: if two hash values (hash values) are not identical (according to the same function), then the original inputs of the two hash values are also not identical. This property gives the hash function a deterministic result. On the other hand, the input and output of the hash function are not one-to-one, and if two hash values are identical, the two input values are identical (in the case where there is no extremely small probability of hash collision).
And 104, determining whether the information to be authenticated is consistent with the original information or not based on the relation between the hash value to be authenticated and the first hash value and the second hash value which are stored in advance.
Specifically, the first hash value and the second hash value are generated and stored in the process of storing the certificate, please refer to fig. 2.
FIG. 2 is a diagram illustrating a method for generating a first hash value and a second hash value according to the embodiment shown in FIG. 1.
As shown in fig. 2, the method for generating the first hash value and the second hash value (i.e. the evidence storing method) specifically includes:
The specific method for determining the processing policy corresponding to the original information is the same as the method for determining the processing policy corresponding to the information to be authenticated, and reference may be made to the description of step 101.
Similarly, based on the corresponding processing policy, the processing mode of the original information can be obtained, including extracting the original data file to be packaged from the original information and performing packaging processing.
Based on the same hash function, a hash value of the packed file is calculated to obtain an original hash value.
And 204, uploading the original hash values respectively and ensuring the original hash values in a server database and a block chain so as to generate a first hash value and a second hash value correspondingly.
After the original hash value is obtained, in order to enhance data security, the original hash value may be uploaded and stored in a database of the background server and on the block chain, respectively, so as to obtain a first hash value stored in the server database and a second hash value stored in the block chain.
And when the original hash value is uploaded and stored into the block chain, the block chain stores the original hash value as a second hash value, returns corresponding extraction information, stores the extraction information corresponding to the second hash value into the server database, and generates a mapping relation with the first hash value. In other words, the server database stores not only the first hash value but also the extracted information returned by the block chain.
Preferably, in the embodiment of the present invention, the blockchain may be an etherhouse sidechain, and the etherhouse sidechain is used in the scheme. The side chain has the advantages of few nodes, high transaction speed and good privacy, so that the privacy of the data inside the enterprise is guaranteed, and the data is prevented from being leaked outwards.
It should be noted that the original information may be uploaded to the cloud storage server for storage for subsequent verification to complete the storage of the original information. The original information is uploaded to the cloud storage server, so that the original information can be prevented from being tampered through a local system, the safety of data storage is improved, and the storage pressure of the local system can be relieved.
According to the evidence storage method, the original information is processed based on the pre-configured processing strategy, namely, a specific data file is selected for packaging, the packaged file is calculated based on the hash function, the hash value corresponding to the original information is obtained, and the hash value is stored in the background server database and the block chain respectively, so that the classification processing of different business requirements can be realized, the file cracking difficulty is increased, the original hash value is stored in different modes, the data safety hidden danger caused by the fact that a single storage device is invaded can be further avoided, and the data tampering difficulty is increased.
Please return to step 104 in the embodiment shown in fig. 1.
Specifically, a method for determining whether the information to be authenticated is consistent with the original information based on a relationship between the hash value to be authenticated and the first hash value and the second hash value stored in advance may refer to fig. 3.
As shown in fig. 3, the method may comprise the steps of:
And extracting the second hash value.
if the authentication information is the same as the original information, the information to be authenticated is determined to be consistent with the original information, and the authentication is successful; if not, the authentication fails.
Therefore, the embodiment provided by the invention combines the block chain with the business handling process, and provides a hierarchical multi-factor authentication process scheme based on the block chain. And according to a preset processing strategy, the service is distinguished into different processing grades, each file in the handling process is processed according to the situation grade, and finally, corresponding information is respectively stored in a server database, a block chain and a cloud storage server. When the business process needs to be authenticated, the corresponding hash value is calculated only based on the corresponding processing strategy, and is compared with the two hash values for storing the certificate. In the process, if any step is tampered, the calculated hash value is different from the certified hash value, authentication failure can be determined, the safety and the reliability of the business process are improved, and meanwhile the speed and the efficiency of the business authentication are improved.

For example, a judgment standard and a threshold n of a service level may be set, for example, the small amount transfer service level is 1, the large amount loan service level is m (m < n), and for different service levels, a corresponding processing mode may be set, for example, when the service state level is 1, a single factor in the identity information, the face image, and the GPS data is packaged; when the state grade is m, packing certain m factors in identity information, face images, GPS data, certification documents and the like; when the situation level is equal to or exceeds the threshold value n, all materials such as the identity information, the face image, the GPS data and the like need to be packed uniformly at the same time, and an overall packed file is obtained.
In the process of storing the certificate, when a business applicant transacts the related business through terminal equipment or is assisted by counter personnel, related file data needs to be provided according to business requirements, and the related file data specifically comprises an identity card electronic file, various application form electronic version files, electronic files of various certificate files, a face recognition information file, Global Positioning System (GPS) information of a transaction location, and a video file in the transaction process, the transacted business type, the business content and other original information.

And meanwhile, the hash value is stored in a database of a background server, and the hash value and the extraction information returned by the block chain are correspondingly stored. Thereby completing the evidence storage process.
In the authentication process, the service applicant needs to submit corresponding information to be authenticated to the client, which may specifically include electronic documents of the identification card, electronic version documents of various application forms, electronic files of various certification documents, face recognition information documents, GPS (Global Positioning System) information of the transaction location, and record video files of the transaction process, the transaction type, the service content, and the like.
After receiving the information to be authenticated, the client acquires a corresponding processing strategy from a pre-stored processing strategy file based on information such as a service type and the like, compresses and packages a corresponding data file according to requirements in the processing strategy, and calculates a hash value to be authenticated of the packaged file. And searching the corresponding hash value from the database, comparing, and if the hash values are different, failing to authenticate. If the hash values are the same, the corresponding hash values are continuously extracted from the block chain through the extraction information and are compared again, if the hash values are different, the authentication fails, and if the hash values are the same, the authentication succeeds.
