Description
Technical field
The present invention relates to hash algorithm technical field, and in particular to the electronics based on cellophane paper is examined with paper document integrality
The method and system looked into.
Background technology
In flow is borrowed by bank, building staff introduces client and handles housing loan industry to bank after being discussed with client
Business, after bank clerk fills in customer information in electronic document page, print and allow client to be signed in paper document, client
Come and go away several times, if housing loan files electronic version is placed on into housing corporation, make client not have to run repeatedly, then due to housing loan file
Although electronic edition prior art can not be changed, easily replaced, cause formatted documents not to be inconsistent with paper document, to silver
Row brings risk.
Therefore, it is badly in need of a kind of simply and easily e-file and paper document uniformity, the method for integrity checking and is
System.
MD5 is a kind of widely used hash function of computer safety field, to provide the integrity protection of message.Should
Algorithm is used to ensure that information transfer is completely consistent.It is one of widely used hash algorithm of computer（Digest algorithm, Hash are translated again
Algorithm）, generally MD5 has been realized main flow programming language.By data（Such as Chinese character）Computing is another fixed-length value, is that hash is calculated
There are MD2, MD3 and MD4 in the basic principle of method, MD5 predecessor.
MD5 effect is to allow Large Copacity information to be protected before private key is signed with digital signature software by " compression " into one kind
Close form（Exactly the byte serial of a random length is transformed into the hexadecimal number word string of a fixed length）.In addition to MD5,
Wherein more famous also has sha-1, RIPEMD and Haval etc..
The content of the invention
The embodiments of the invention provide the method and system of the electronics based on cellophane paper and paper document integrity checking with
Solve the problems, such as that file is replaced.
An object of the present invention is effectively to prevent file to be replaced.
The present invention is achieved through the following technical solutions above-mentioned purpose.
The method and system of electronics and paper document integrity checking based on cellophane paper, including：Taken including banking
Be engaged in device, OCR devices, master file processing unit, from document handling apparatus, superposition printing equipment, cellophane paper.
Banking server is used for handling bank business, and Hash Value is calculated with hash algorithm.
OCR devices are used to carry out Text region.
Master file processing unit is used to do banking according to flow in bank office；For checking e-file and paper
Whether matter file is consistent.
It is used to do banking according to flow in building office from document handling apparatus；For download formats electronics text
Part, merge with customer data and be printed as paper document.
Superposition printing equipment is used to receive customer information, is superimposed upon on formatted documents, is printed with printer.
Cellophane paper is used to the Hash Value on paper document come out Hash Value by same format print, is then placed on papery
On Hash Value on file, if overlapped, it is consistent, if not overlapping, represents that paper document is not inconsistent with e-file.
Hash algorithm can be other hash algorithms of MD5, sha-1, RIPEMD, Haval and authorized by state.
The method and system of electronics and paper document integrity checking based on cellophane paper, it is characterised in that job step
It is as follows.
Step 1：Client is determined to buy house on loan in building, and money is being filled in from document handling apparatus in the case where staff assists
Material.
Step 2：Banking server carries out hash algorithm computing to every page of form housing loan contract and alternative document, and will
Hash Value A is recorded on every page file, while send Hash Value A to master file processing unit.
Step 3：It is electric from document handling apparatus from banking server download formats housing loan contract and alternative document, locking
Subfile can not change.
Step 4：From document handling apparatus by superposition printing equipment by customer data isochronous printing in form housing loan contract and
The underscore part of alternative document.
Step 5：After bank receives form housing loan contract and alternative document, swept by master file processing unit by OCR devices
The word for identifying non-underscore part is retouched, and Hash Value B is calculated with hash algorithm by banking server, is printed upon miscellaneous
Gather below value A.
Step 6：Hash Value A is printed upon on cellophane paper by master file processing unit.
Step 7：Hash Value A on cellophane paper is placed on the Hash Value A of paper document, Hash Value B by user, if phase
Symbol, then it is overlapped, if not overlapping, represent that paper document is not inconsistent with e-file.
The beneficial effect of the inventive method is：Effectively file is prevented to be replaced.
