The information that supplier is necessary when must must improve company profile when opening the transaction Room and sign a contract, during purchaser's commodities purchased, it is necessary to the information needed when first improving individual or company information and sign a contract.
As one embodiment of the present of invention, when purchaser chooses the commodity needing to purchase and reaches an agreement with supplier, enter native system contract preview page, system program goes out, to data base querying, the contract template information that purchaser selects the product concluded the business and supplier to draw up according to the Customs Assigned Number of purchaser, using foreach cycle calculations to go out commodity single-piece subtotal price, commodity total price and the information such as turnover and Payment Methods at the page to display, purchaser need to fill in the information such as supply time, ship-to, duration of contract.Above essential information collecting work can complete in essential information receiver module.
After purchaser completes above operation, when clicking on confirmation contract button (validation of information module), system automatic shield confirms contract button, prevention purchaser again taps on submission data, cause error in data, after system receives the data that user submits to, system is contract terms data data separation automatically, order commodity data, user profile data etc., contract terms and user profile are saved in south transaction net www.nffair.com contract signing database table, Contract NO according to user profile and generation generates order table and information of goods information data is saved in the detailed table of order simultaneously, finally judge that data above preserves the most wrong, rollback database function is then used as wrong, preserving successful data dump, again preserving, until data preserve successfully, electronic contract generates successfully since then.
nullThe phone number that system is filled on contract according to purchaser sends identifying code of signing a contract，Purchaser only need to input the contract that the receives identifying code that confirms to affix one's seal and complete contract and affix one's seal，Identifying code such as purchaser's input is correct，Automatic Program according to purchaser sign a contract name generate official seal lid to simultaneity factor on contract automatically to supplier provide phone number send purchaser's product purchasing information，After supplier receives short message prompt of signing a contract，Enter the change release administration page of commercial center，The page checked by click contract，Confirmation contract consult with both sides consistent after，Click contract confirms to affix one's seal button，The phone number that system is signed a contract according to supplier sends contract and confirms to affix one's seal short message verification code，After supplier inputs correct identifying code，The name that system is signed a contract according to supplier generates official seal and covers display and system on the page and judge that purchaser and supplier both sides affix one's seal，As both sides affix one's seal, system generates anti-fake two-dimension code automatically according to the affix one's seal information encryption of time turnover of the Customs Assigned Number of both sides，After Quick Response Code generates successfully, system regeneration becomes PDF contract documents and is sent to the mailbox that both sides sign a contract，Both sides are facilitated to download preservation，Generation of signing a contract the most online completes.
The Quick Response Code content of native system all employs the DES algorithm for encryption of self-control research and development, and the symmetric cryptography mode of non-generic is encrypted.
Symmetric cryptography refers to: symmetric encipherment algorithm is to apply AES earlier, technology maturation.In a symmetric encryption algorithm, data transmission side will in plain text (initial data) with encryption key together with after special AES processes so that it is the encrypted cipher text becoming complexity sends.After destination receives ciphertext, if wanting to understand original text, then need to use the algorithm for inversion encrypting used key and identical algorithms that ciphertext is decrypted, it just can be made to revert to readable plaintext.In a symmetric encryption algorithm, the key only one of which used, sending out collection of letters both sides all uses this data key to encrypt and decrypt, and this will ask decryption side to must be known by encryption key in advance, as long as the people that symmetric cryptography do a harm to have key can decipher.It is the most this to your cipher mode that native system uses, and is the use of asymmetric encryption.
Asymmetric encryption refers to: asymmetrical encryption algorithm use two entirely different but be a pair key PKI and private key mated completely.When using asymmetrical encryption algorithm encryption file, only use a pair PKI and the private key of coupling, just can complete encryption of plaintext and decrypting process.Use public key encryption during encrypting plaintext, use private key just can complete during decrypting ciphertext, and originator (encipherer) knows that the PKI of destination, only destination (deciphering person) are only the people uniquely knowing oneself private key.The ultimate principle of asymmetrical encryption algorithm is, if originator is wanted to send, only destination could understand adds confidential information, and first originator must know the PKI of destination, then utilizes the PKI of destination to encrypt original text；After destination receives encrypted cipher text, the private key using oneself could decrypting ciphertext.Obviously, using asymmetrical encryption algorithm, before a communication, the PKI of oneself stochastic generation already must be given originator to transmitting-receiving letter both sides by destination, and oneself retains private key.Thus significantly ensure that the authentic security of user profile is effective.
Present invention uses digital signature, the meaning of digital signature is exactly whether these data were revised with plaintext data comparison.It is usually and with the private key of oneself, data is signed, then go to verify whether these data were revised with PKI.
Database access layer employs the DbHelperSQL class of self-control research and development, mainly effectively encapsulating substance parameter is converted to SQL parameter problem, solve each data bank access method to be required for creating a data parametric technique, it is achieved that method is general, implements main method as follows:
1, creating a return value is SqlParameter parameter universal method, and the method needs incoming three parameters, respectively SqlCommand, SQL statement or storing process name variable, parameter type etc.；
2, creating one and be worth to the method for SqlParameter parameter assignment without return, the method also needs incoming three parameters, first parameter: SqlCommand, second parameter: correspondence database field parameter title, the 3rd parameter: the value that user object is incoming.
3, create again return value be the method for SqlCommand to call two above method, the method only needs an incoming value parameter of object；
4, create Universal Database operational approach, need three parameters, first parameter: SqlCommand, second parameter: perform SQL statement or store process title, 3rd parameter: whether be storage process, if process IsProc of storage is True, SQL statement is False.
When 5, calling database manipulation universal method, need first instantiation SqlCommand, thus can solve user when submitting data to, concurrent and the fatal error of error in data caused because network is slow, call every time and all create a new SqlCommand object, ensure that SqlCommand is the most general, when call parameters assignment method, only the data that SqlCommand good for instantiation and the page submit to need to be participated in, calling, after SQL parameter establishment assignment is complete, the database manipulation that database access layer completes to be correlated with.
The Cache caching technology that native system uses in product information page, on some data buffer storages to server, is updated information in timing, and user does not use data base's value when not accession page, and the pressure and the user that effectively reduce data base are exceeded the speed limit to access and experienced.
Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert the present invention be embodied as be confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
