Background technology
At present, the application of electric signing tools is more and more extensive, and particularly in financial industry, in order to guarantee the fail safe of transaction, the user of Web bank uses electric signing tools more and more, such as USB Key, as the means of authentication and transaction authentication.
In order further to guarantee the fail safe of electronic transaction, the electric signing tools of a new generation has Presentation Function conventionally, and soon in this transaction, some are shown to user with the form of word by display screen than more sensitive Transaction Information.
Specific implementation comprises: electric signing tools is connected with personal computer (PC) by USB (USB) interface, PC receives the Transaction Information of user's input, according to this Transaction Information, generate transaction message, and send to electric signing tools; Electric signing tools extracts specific Transaction Information (extracting which Transaction Information consults in advance) from the transaction message receiving, and as transaction account, dealing money and address name etc., and is shown to user with the form of word; Like this, whether user can be accurate by the Transaction Information of this transaction of content check of demonstration, and after the button only arranging on by electric signing tools user confirms that Transaction Information is accurate, electric signing tools just can send trading instruction, thereby greatly improves the fail safe of electronic transaction.
Since need to carry out word demonstration, preserve the type matrix of corresponding word in so just need to the character library in electric signing tools.But, the word that user may input is various, such as, in certain user's name, may comprise the rarely used word of some fewer use, and the limited space of character library in electric signing tools, can not preserve the type matrix of all words, thus will cause this class word normally to show, thus make troubles to user's use.
Have, electric signing tools when showing Transaction Information, needs to consider how to show problem attractive in appearance, needs to consider line feed and word space again.What show due to existing electric signing tools is all Chinese and digital conventionally, so line feed and adjust word space all than being easier to; But if user uses the language of other kind, during such as English, Russian, French, Japanese, Arabic etc., realize line feed and adjust word space will be cumbersome.Take English as example: for a word question, if need line feed, can only be split into so ques-tion, and can not split into the forms such as q-uestion or qu-estion; In addition, alphabetical display width as i the obviously letter more such than s is narrow, if adopt equal word space, can be more ugly, but existing electric signing tools does not also carry out the self-adjusting function of display mode according to the difference of Transaction Information to display, so limited the scope of application of electric signing tools.

Embodiment
Consider if overcome problems of the prior art by the related software changing in electric signing tools, that development difficulty or development cost all can be larger, and follow-up when needs upgrade software, upgrade cost and safety cost also all larger, so in scheme of the present invention, by PC, the Transaction Information that needs electric signing tools to show is carried out to preliminary treatment, all Transaction Informations are entered a new line and the setting such as word space, then the every row Transaction Information setting is processed into respectively to a picture, specifically how to be treated to known in this field, afterwards, more than one picture (picture number is depending on line number) of handling well is sent to electric signing tools, electric signing tools is shown to user by more than one picture receiving successively according to receiving sequencing.In actual applications, the mode that can adopt a picture to take a line shows, or, if amount of information is less, also can several rows (being greater than a line) show a picture, specific implementation is not limit.
For making object of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 1 is the flow chart of the inventive method embodiment.Suppose that the electric signing tools in the present embodiment is USB Key, and the mode that adopts a picture to take a line in hypothesis the present embodiment shows to more than receive one picture.As shown in Figure 1, comprise the following steps:
Step 101:PC machine is processed into more than one picture by the Transaction Information that needs USB Key to show in this transaction, and sends to USB Key.
Other before this step is operating as known in this field, repeats no more.
In this step, PC, by the Transaction Information that needs USB Key to show, as transaction name, dealing money and transaction account etc. are processed into more than one picture, such as the picture of bitmap form, sends to USB Key.Concrete how to enter a new line etc. is ripe prior art for PC, so implement easily, and the space (capacity) of the character library in PC is conventionally all larger, so for the word not having in some USB Key, conventionally also can find with comparalive ease in PC.
It should be noted that, " word " mentioned in the present embodiment, is the general designation to various types of words, does not specially refer to Chinese text or numeral.
The mode that step 102:USB Key takies a line by the more than one picture receiving with each picture is shown to user.
In the present embodiment, can in USB Key, set rule in advance, if receive this class picture, how this processes, and so follow-uply receives from more than after picture of PC as USB Key, and the mode that can automatically it be taken to a line with each picture shows on display screen.
Step 103:USB Key signs to more than one image data, and the data after signature are sent to background server.
USB Key is shown to the Transaction Information receiving after user, determine whether to receive the confirmation from user, if, more than receive one image data is signed, concrete signature scheme is known in this field, and the data after signature are sent to background server by PC.Here the background server mentioned, the server that bank that refers to this transaction of actual treatment etc. is used.
In addition, according to actual needs, the PC corresponding transaction message (being generated according to the Transaction Information of user input by PC) of also can further this being concluded the business sends to USB Key, so in this step, USB Key also can sign to this transaction message simultaneously, and by PC, the data after signature is sent to background server.
Step 104: background server verifies that whether the signature receiving is correct, if so, performs step 105; Otherwise, execution step 106.
In prior art, PC can send to background server by the transaction message of generation, so that background server carries out corresponding trading processing according to this transaction message.In the present embodiment, background server is after the transaction message receiving from PC, according to the mode identical with PC, the information processing that needs USB Key to show in this transaction is become to more than one picture, and utilize this more than one picture being processed into verify the signature of the image data receiving, if the verification passes, perform step 105, otherwise, execution step 106.Or, also can directly more than one picture being processed into be sent to background server by PC, and regenerate again without background server, but because the data volume of picture is conventionally larger, so generally do not adopt in this way.And the benefit of front a kind of processing mode is also: because PC and background server are to carry out identical processing for identical transaction message, so should obtain in theory identical picture; Like this, if transaction message is modified in the process that sends to background server, the picture that the picture that background server obtains so will obtain with PC is different, and like this, signature verification will be passed through, thereby has improved fail safe.
In addition, if USB Key signs to transaction message in step 103 simultaneously, in this step, background server also needs further the signature of the transaction message receiving to be verified so.
How signature is verified as to prior art, repeats no more.
Step 105: carry out subsequent transaction processing, process ends.
Step 106: end this transaction, process ends.
Step 105 and 106 specific implementation and follow-uply whether also need to carry out other operation and wait with scheme of the present invention and have nothing to do, be not described.
