Literary transaction data is checked, if the field that user submits in plaintext transaction data is present in encrypted domain, is checked and is handed in plain text
The consistency of the field and the field in encrypted domain, shuts the book if inconsistent in easy data.For example, using in encrypted domain
Data check plaintext transaction data, if a field was both submitted in plaintext transaction data, are also stored in encrypted domain
This field then checking the consistency of the two fields stops this transaction if inconsistent, can prevent user in this way
The attack that the data verified are distorted at end or part distorts, and then goes beyond one's commission.
In embodiment, when back page data be one group of enumerated value, the data of back page are carried out with encryption key
Encryption generates encryption numeric field data, may include：It is preserved, is generated with encryption keys using this group of enumerated value as a list
Encrypt numeric field data；Plaintext transaction data includes the enumerated value that user selects in this group of enumerated value；It checks in plaintext transaction data
The consistency of the field in the field and encrypted domain may include：The enumerated value of user's selection is in verification plaintext transaction data
It is no to enumerate value list in encrypted domain, if not shutting the book if.For example, being enumerated back to one group on the page for backstage
The data of value, user select the transaction sent in wherein a certain value on the page, and for example user inquires account row in e-bank
Then table selects the transaction of one of account inquiries details, is protected all enumerated values as a list encryption in encrypted domain
It deposits, enumerated value list name is consistent with the field name that transaction is submitted.After transaction is submitted, it can check that user terminal is submitted according to field name
Value whether in the field of encrypted domain enumerate value list, be normally carried out transaction if comparing successfully, lost if compared
It loses, shuts the book.
Fig. 8 is that anti-scheme exemplary plot of going beyond one's commission is encrypted in the embodiment of the present invention, as shown in fig. 7, implementation process can for example wrap
It includes：81, user is initially opened Website page；82, server creates session, and generates encryption key；83, user logs in and enters
Transaction；84, server obtains background query data and the data encryption that typing is walked before user, are put into the hiding field of the page
In (encrypted domain)；85, user typing, confirmation and submits transaction on the page, while submitting encrypted domain field；86, server end
The data that user submits are compared to whether there is in encrypted domain, and if so, whether both comparisons are consistent, if it is inconsistent,
There is attack of going beyond one's commission in judgement, and blocks this transaction.
It, can be by if the field name of the passback page of original system and the field name submitted again are all consistent in embodiment
Above-described embodiment reinforces system, it is only necessary to develop a public encryption and veritify component, so that it may with to all passback pages
The field in face is encrypted, and transaction is veritified when submitting, without making modification to particular transactions.Or, or it is each
A configuration is write in transaction, is maintained in configuration file, including this transaction will encrypt the field of veritification.
In embodiment, by the way that the transaction number for being related to operation flow is added in encrypted data fields, transaction step is numbered, and
It is submitting the when of merchandising to check transaction number and transaction step, can prevent user terminal from arbitrarily calling a certain step of transaction, prevent
Stride attack.For example final step of transferring accounts directly is sent to server and completes the attack transferred accounts.
The safety check process of the embodiment of the present invention can also use another embodiment, that is, ignore the data submitted in plain text,
And it is subject to the data in encrypted domain and is traded.For enumerating value list, then can select to carry in plain text by user on the page
Enumerated value serial number is handed over, enumerated value is then taken out from encrypted domain according to serial number, obtains the data of user's selection.That is, when returning to page
When the data in face are one group of enumerated value, plaintext transaction data includes the serial number for the enumerated value that user selects in this group of enumerated value；
According to data control transaction in the encrypted domain decrypted, may include：According to the serial number of enumerated value in plaintext transaction data, from adding
Corresponding enumerated value is taken out in enumerating for close domain in value list, obtain the enumerated value of user's selection；The enumerated value selected according to user
