The verification of the image file in the bank credit wind control scene in the prior art has the following problems and defects:
1. and in the manual approval link, whether each image meets the requirements or not needs to be approved one by one, the time and effort are consumed, the risk of misjudgment caused by human negligence exists, and an auxiliary auditing tool is lacked.
2. The automatic approval link is usually simply used for judging whether an image file and a corresponding image type exist or not, but does not further check whether the content of the image file and the current financing application are adapted or not, and a certain approval vulnerability exists.
3. File transmission links, such as pictures and pdf files, have the possibility of being tampered in the financing initiation or transmission process.
4. Signature image files, such as electronic signatures, may not be the subject of the present financing application for the file signer information.
5. And after the credit system receives the image file, the credit is transferred to a storage or submitting image platform, and the acceptance label is absent, so that hidden danger that the image file is replaced exists.
As shown in fig. 6, in the prior art, a simple image interface is used for docking, so as to directly receive a request message and an image file, and after decompression, the request message and the image file are directly transferred to be stored or submitted to an image platform. The disadvantages of the prior art are:
1. MD5 verification is not performed on the image file, and the risk of man-in-the-middle attack tampering exists.
2. Without zip bomb verification on the image file, bandwidth-saving compressed zip transmissions may present a risk of the zip bomb causing a disk explosion of the application server.
3. The image file has been electronically signed, but it has not been verified whether the signature entity is the current credit financing entity.
4. The image file is often a contract text output by credit, and after the contract text receives a signature, whether the contract text is tampered and replaced or not lacks verification anti-counterfeiting.
5. The image contract file and the key business data verification such as interest rate, money amount, repayment date, and information way need to be matched with the present credit financing application.
6. The lack of credit acceptance image files for signature verification directly stores or submits to a third party image platform, and the possibility of being tampered and replaced exists.
The invention relates to a method and a device for automatically checking image files, which are suitable for a bank credit wind control scene, and mainly solve a series of problems that key image files such as warranty borrowing contracts, credit investigation and authorization books and the like possibly exist such as illegal signature bodies, tampered and replaced image files, no signature checking after the image files are received and the like when a third party channel applies for a credit financing service to a bank.
Fig. 7 is a flowchart of the whole method of the present invention, and as shown in fig. 7, the method for verifying an image file in a bank credit wind control scene of the present invention specifically includes: access authentication, physical verification, logical verification, signature reception and image uploading platform.
Fig. 1 is a first flowchart of a method for verifying an image file in a bank credit wind control scenario according to an embodiment of the present invention, as shown in fig. 1, in an embodiment of the present invention, the method for verifying an image file in a bank credit wind control scenario includes steps S101 to S104.
Step S101, obtaining an image file compression packet sent by a channel side.
Step S102, determining physical verification for the image file compression package.
This step is mainly directed to some hard checks of the file itself.
And step S103, after the physical verification is passed, carrying out file anti-counterfeiting verification and file data verification on the image file in the image file compression package.
The step is mainly to verify from the aspect of whether the actual service needs are met.
Step S104, after the file anti-counterfeiting verification and the file data verification pass, signing and accepting signatures are added to the image file, and the image file after signing and accepting signatures is uploaded to a preset image platform.
As shown in fig. 2, in one embodiment of the present invention, the method for verifying an image file in a banking credit wind control scenario further includes steps S201 to S202.
Step S201, when receiving the image verification request sent by the channel side, performing access authentication on the channel side.
When the invention receives the image verification request sent by the external channel side, authentication processing is firstly carried out, wherein the authentication processing comprises user name and password, request decryption and analysis, and the key message structure is shown in figure 8. The input file list message covers key information required by MD5 verification, electronic signature verification, anti-counterfeiting verification and business data verification.
Step S202, after the access authentication is passed, storing the image file compression packet corresponding to the image verification request in a local temporary storage area.
In one embodiment of the present invention, the image file compression packet sent by the obtaining channel side in the step S101 specifically includes:
and acquiring the image file compression package from the local temporary storage area.
As shown in fig. 3, in one embodiment of the present invention, the determining physical verification for the compressed package of the image file in the step S102 specifically includes a step S301 and a step S302.
Step S301, performing MD5 verification on the compressed video file packet.
As shown in fig. 9, MD5 is a popular message digest algorithm that can produce 128 bits of three inferior quality and can be used to confirm the consistency of message transmission, and the image file does not need to be verified by a strict encryption algorithm like the user password.
In one embodiment of the present invention, the present invention performs MD5 verification not only on the image file compression package, but also on each image file in the image file compression package.
Step S302, anti-compression package bomb verification is conducted on the image file compression package.
In one embodiment of the present invention, the image file compression packet of the present invention is a Zip compression packet. The present invention requires anti-compaction packet bomb verification (i.e., zip bomb verification). Zip frying refers to a compressed file with high compression ratio, although a credit system and the like possibly take a limiting measure on the uploading size of the file, when a file with high compression ratio reaches the credit system and the like, the file is recursively decompressed in the background, so that the file such as a CPU, a memory, a disk and the like continuously operates under high load, and a DDOS denial of service attack effect is generated.
In one embodiment of the present invention, the step S103 of performing file anti-counterfeit verification on the image file in the image file compression package specifically includes:
and verifying the electronic signature of each image file.
In one embodiment of the present invention, the image file of the present invention is specifically a PDF file. Fig. 10 is a schematic diagram of electronic signature verification, in which, based on a PDF file, a Hash algorithm and an encryption algorithm are utilized to realize a PDF file signature, so as to realize the tamper-proof characteristic of the PDF file, and the current PDF electronic signature technology belongs to the industry general technology.
As shown in fig. 4, in one embodiment of the present invention, the step S103 performs the file anti-counterfeit verification on the image file in the compressed package of the image file, and specifically includes step S401 and step S402.
Step S401, extracting the document signing order from the image document.
Step S402, verifying the document signing sequence.
Assuming that the original PDF text of the contract is provided by a credit and other business systems, and then transmitted to related platform parties through interfaces, such as an enterprise network bank, a certain supply chain platform, a certain core enterprise ERP system and the like, the circulation sequence is always fixed, and the file is finally returned to the credit system after being signed, so that the closed loop is completed.
The document signing sequence is based on the circulation party signing verification principle, and takes an online banking as an example, and the sequence is as follows:
original sign (system sign), credit system outputs PDF original text, namely initial sign
The credit system outputs PDF business contracts, namely the business labels of the line parties
The system signature is a receipt signature of the internet banking system, and represents the internet banking system level signature.
Transaction signature (business signature), the financing enterprise operates the signature at the bank end, representing the completion of the transaction.
Check-in (system check) and after transaction is completed, the credit system receives and adds the check-in to complete closed loop
The sequence is a fixed execution sequence, and once the intermediate link sequence is not matched or missing, the financing application is denied.
The invention can extract the document signing sequence from the image document by an open source Java item 5 tool, thereby verifying the document signing sequence.
As shown in fig. 5, in one embodiment of the present invention, the step S103 performs file data verification on the image file in the image file compression package, and specifically includes step S501 and step S502.
In step S501, service data is extracted from the image file.
Step S502, the service data is verified.
File data verification is mainly based on the reasonability of PDF file service data, solves the problems of tampering of service data or unmatched current financing application and the like, and is exemplified by: the PDF contract original should be the corresponding value under normal conditions, namely 100 ten thousand of financing application, 4.45% of LPR (line cost per minute) interest rate, 4.45% of floating base point-20 and 360 periods of period, but due to the fact that the transaction link is separated from the credit system, after the PDF signing flow returns to the credit system, the key contract elements are possibly tampered, such as floating point number-30, and legal disputes are extremely easy to cause.
The file data verification is realized as follows:
1. and verifying a key coordinate, namely reading the horizontal and vertical coordinates of the pdf file key word by means of an open source Java item 5 tool in a key word form, and matching with the horizontal and vertical coordinate values preset in a system, wherein an error value threshold can be customized, and the error value mainly solves the problem that the text is moved out after being longer, for example.
2. And (3) verifying the key data, namely performing accuracy verification on the key data, and after reading the pdf key value, performing grabbing matching with the approved flow business data of the credit system, wherein the example is shown in fig. 11.
The invention scans the appointed content in PDF file through the pre-input key value, front sentence and rear sentence, analyzes the content between the broken sentences, and performs matching check with the recorded value of the system database, if the check is not matched, the financing application is carried out this time, the paying operation is overrule, and the instruction is returned to be confirmed by the client manager.
In one embodiment of the present invention, the present invention may convert the image file into text first, and then extract the service data from the text based on a preset regular expression for service data extraction.
Compared with the prior art, the method for verifying the image file in the bank credit wind control scene has the following advantages:
1. and the management and control are enhanced, the closed loop verification of the contract image file is realized, the risk management and control are carried out on the image file related to the interaction process with the third party system, and the loan reject ratio and the potential legal dispute are reduced.
2. The security is enhanced, and the security management and control are carried out from the main links of initiation, transmission, transaction, acceptance and the like, so that the verification blank of the third-party channel for receiving the traditional credit image is made up.
3. The invention is easy to expand, is relatively independent, and can enrich the wind control verification rules of the image file based on different service scenes, thereby providing the automatic verification service of the image file for credit and other service systems.
4. The efficiency is improved, and the method is used as an auxiliary tool for the client manager to examine and approve the contract image, so that the examination and approval accuracy and examination and approval efficiency are further improved.
5. Unified standards, image files, especially critical contract text image automated verification, provide standardized automated verification models or specifications.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
