Below with reference to concrete application example, the enforcement of technical solutions of the utility model is done further and introduced in detail.
Figure 2 shows that the utility model embodiment uses the business process map of realizing processing batch electronic transaction in example, wherein relates to bank's background system, the processing of client and three parts of electronic signature equipment.
As shown in Figure 2, its business step specifically describes as follows:
Step 21, client is collected information;
At this, the client-side program of Net silver can be arranged on the host computer of user's client, and the host computer of client comprises: PC, and intelligent mobile terminal, as: smart mobile phone, panel computer, PDA etc.The user forms original transaction data by using client-side program will collect one or many transactions data, and client-side program is completed subsequently many business information are arranged and pack, and is uploaded to electronic signature equipment.
Step 22, enhancement mode electronics signature device adopt image technique generated data picture;
At this, enhancement mode electronics signature device calls the original transaction data that image processing module will transmit and adopts image technique to generate the image file that comprises whole transaction data.This image file can show in the digital picture mode, is character style as original transaction data: " name: Zhang San; Account: XXXXXXXX XXXX XXXX; The amount of money: 100 yuan ", after it transforms, corresponding performance is shown as the picture form: " name: Zhang San; Account: XXXX XXXX XXXX XXXX; The amount of money: 100 yuan ".In addition, but also original transaction data can be converted into other recognition images arbitrarily, as function curve, apple picture, two-dimension code sign etc., but transform after his picture and original transaction data have correspondence one by one, and one group of original transaction data has and only has and generate a secondary corresponding picture, anyly changes in original transaction data, regardless of changing size, all can't generate identical picture, and picture can be distinguished namely by human eye.Subsequently, enhancement mode electronics signature device shows original transaction data and the image file that generates on this device screen.
Step 23, the image technique generated data picture that customer end adopted is identical;
At this, the image processing mode that customer end adopted is identical with enhancement mode electronics signature device generates original transaction data the image file that comprises whole transaction data.With the described image file of step 22.And subsequently original transaction data and the image file that generates are shown on the client computer screen.
Step 24, enhancement mode electronics signature device carry out carrying out signature operation after physics is confirmed the user;
Enhancement mode electronics signature device can show screen display at it with original transaction data and corresponding image file, original transaction data and image file shown on the information that the user shows enhancement mode electronics signature device and client computer screen carry out manual confirmation, when both identical, the user confirms by the physical operations module on enhancement mode electronics signature device, and equipment signs electronically to original transaction data subsequently.Last enhancement mode electronics signature device is to the client upload electronic signature data, and client sends to bank's background system after original transaction data and electronic signature are packaged into digital envelope.By above step, thereby realize the requirement of " finding is namely signed ".
Further, the image processing module in above-described embodiment, realize that the concrete steps that image is processed are described below:
Step 31, the input of original transaction data;
Wherein, original transaction data is inputted in this module with the form of character string.
Step 32, table corresponding to number carry out numerical value correspondence one by one;
Wherein, according to preformed digital corresponding table, be stored in module, effect of this digital corresponding table is to realize that transaction data and a certain image information are corresponding, thereby realizes the corresponding one by one of original transaction data and image file.At first, original transaction data can be generated corresponding numerical value according to digital corresponding table in this module, these numerical value will be the foundations that image file generates.There are a variety of function ﹠ methords can realize function like this, in the application, this no longer too much set forth.
Step 31, according to numerical value corresponding informance synthetic image information;
At this, according to the numerical value corresponding informance that original transaction data generates, comprise corresponding pixel etc., numerical value as corresponding in " name: Zhang San " is picture pixel " name: Zhang San "; Also can " name: Zhang San " corresponding numerical value be certain a part of picture pixel etc. in the apple figure.Finally, at this, image processing module can be converted into original transaction data a discernible image file.
in sum, the utility model proposes a kind of electronic signature equipment and system based on image technique, its implementation is to have increased display module on as USBKey in traditional electronic signature equipment, the physical control module, and expanded communication module, as when keeping traditional USB interface, increased voice communication etc., equipment can realize that the finding in data transmission in network is institute's label problem, effectively defendd man-in-the-middle attack, particularly there is good protection to do for Internet bank's transfer of data, and this equipment can effectively be supported intelligent mobile terminal equipment, as mobile phone, PDA, panel computer etc.The utility model also provides the processing method of transaction data being carried out carrying out based on the image generation technique man-to-man conversion simultaneously, convenience and interest that the user compares data have been increased, mass transactions velocity and the recovery efficiency of big data quantity have also been accelerated, solved because screen in the conditional electronic signature device is too small, device processes is limited in one's ability, the user who causes can't comprehensively examine electronic transaction content in enormous quantities, and the security breaches problem that inspires.
These are only preferred case study on implementation of the present utility model; be not limited to the utility model; the utility model also can have other various embodiments; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
