Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
In the present invention, the part that does not need to adjust can be regarded as to the static cell of E-seal, and regard the various parameters of adjusting as needs such as numbering, date, times as dynamic cell in E-seal.
Figure 1A is the complete image schematic diagram of a certain E-seal, Figure 1B is that the static cell of this seal (is constant part during seal shows, with external environment condition and method of operating, there is not the variation showing in it) schematic diagram, the dynamic cell of this seal (be often need during seal shows change, adjust part) is numbering and date in E-seal as shown in Figure 1A, numbering in seal is often affixed one's seal once will increase by 1 automatically, be numbered when affixing one's seal for the first time " 0001 ", while affixing one's seal for the second time, numbering becomes " 0002 ", by that analogy; Date in seal constantly changes the difference along with the date of affixing one's seal, such as the chapter at lid on September 10th, 2005, the date in seal is shown as " on September 10th, 2005 ", if the chapter covering on September 11st, 2005, the date in seal is " on September 11st, 2005 ", by that analogy.In this example, seal dynamic cell does not comprise time parameter, time parameter and date parameter are similar, it is the time for representing to affix one's seal, such as: certain E-seal dynamic cell has time parameter, when the time of affixing one's seal, be 16: 30 timesharing in one day, the time parameter of this seal is shown as " 16: 30 ", in addition, the degree of accuracy of this time parameter can be determined as required, such as can be accurate to as required minute or second.If certain E-seal need to show date and the time of affixing one's seal in seal, this seal dynamic cell had both comprised that date parameter also comprised time parameter, for example, if this seal is the chapter of lid when 16: 30: 30 on the 10th September in 2005, the date and time parameter of this seal dynamic cell can be shown as " 16: 30: 30 on the 10th September in 2005 " altogether.
When chapter processed, the parameter that the die of need making E-seal static cell definite E-seal dynamic cell are included and the attribute of each parameter.Wherein, the attribute of parameter is in order to retrain the behavior of corresponding parameter, and the attribute of parameter can comprise one of the following or combination arbitrarily: the position of parameter, font, font size, color, spacing, form, classification, source etc.
The E-seal of take below is as shown in Figure 1A example, illustrates the chapter processed of E-seal in the present invention, the realization flow of affixing one's seal and being stamped the demonstration of E-seal document.
One, Zhang Liucheng processed
Referring to Fig. 2, the chapter process flow diagram processed that Fig. 2 is E-seal, as shown in Figure 2, this flow process comprises the following steps:
Static cell is that seal display effect is according to actual needs determined, for E-seal as shown in Figure 1A, its static cell as shown in Figure 1B.The making of die can complete by the modes such as combination of page-description language or image or page-description language and image.
Dynamic cell comprises parameter and parameter attribute, according to the display requirement of seal, first which parameter clear and definite dynamic cell comprises, then determine display effect and the type-setting mode of each parameter, thereby determine the attribute of each parameter, in the attribute of dynamic cell parameter, comprised the positional information of dynamic cell with respect to static cell, dynamic cell and static cell are combined as complete E-seal according to this positional information just.
The numerical value of each parameter of dynamic cell generally will could be determined, in the time of chapter processed, can not determine when affixing one's seal; And for the property value of each parameter, be likely both to determine when affixing one's seal, be likely also in chapter processed, just to have determined and once just determining no longer change, belonging on earth which kind of situation will determine according to actual conditions.
For E-seal as shown in Figure 1A, the parameter of dynamic cell and the attribute of parameter are as follows:
Parameter 1: numbering.
Parameter 1 attribute: 1. originate: server (specific address that comprises server); 2. color: redness; 3. font: the Song typeface; 4. position: (left 30, and top 40).
Above-mentioned position attribution is a relative position, and its value provides with the form of similar coordinate, is that to take the left side of static cell outer rim be left 0 in this example, and the top of outer rim is top 0.Left 30 represents that parameter 1 is 30 pixels apart from the vertical range of static cell left frame, top 40 represents that parameter 1 is 40 pixels apart from the vertical range of static cell upper side frame, both are that (left 30 altogether, top 40), represent that parameter 1(is number parameter) with respect to the position of static cell.
Parameter 2: date.
Parameter 2 attributes: 1. originate: server (specific address that comprises server); 2. color: redness; 3. font: the Song typeface; 4. position: (left 2, and top 60).
For E-seal as shown in Figure 1A, what reality changed is only the numerical value of numbering and date parameter, and for example numbering is " 0001 " or " 0002 ", and the date is " on September 12nd, 2005 " or " on September 13rd, 2005 ".In this example, numbering and each property value on date are determined when chapter processed, and just no longer change after determining, property value is with numbering and the change of date numerical value does not change.Certainly, if this example is slightly changed, such as the color attribute value of these two parameters is changed into, be redness or black, and to when affixing one's seal, could determine that property value is redness or black (numbering and the date parameter that are seal are shown in red or black), and remaining is all constant, property value so is now exactly: the property value having (source, font, position) is when chapter processed, to be just determined and no longer change, and some property values (color) are when chapter processed, can not determine and will when affixing one's seal, could determine.
Identity (such as using chapter person's processed private key) with chapter person processed is signed to whole seal data, obtains the result of signing, and the whole seal data here comprise static cell and the dynamic cell (dynamic cell comprises parameter and the attribute of dynamic cell) of seal.Seal is signed to protect and can make seal not be tampered and not be forged.
Store seal data into specific memory device or server.These seal data are by static cell, the dynamic cell of seal and the signature result of this seal is formed, but it is to be noted, the numerical value that does not comprise each parameter of seal dynamic cell in these seal data, for example, to E-seal as shown in Figure 1A, the numerical value that does not comprise number parameter and date parameter in the seal data here, the numerical value of these two parameters will just can be determined when affixing one's seal.
In addition, the static cell of E-seal can be also sky, the all displaying contents of this seal are all dynamic cell, such as, one only by the E-seal as seal numbering is formed in Figure 1A, the die of now step 201 making static cell is makes a blind printing mould (this die image is for empty), and remaining chapter step processed is just the same.
Two, the flow process of affixing one's seal
Referring to Fig. 3, the process flow diagram of affixing one's seal that Fig. 3 is E-seal, as shown in Figure 3, this flow process comprises the following steps:
The seal data that read storage from deposit the memory device of seal data, these seal data comprise dynamic cell and static cell and the signature result to seal.
These seal data that checking is obtained: judge whether its signature is correct, thereby guarantee that these seal data are not tampered or destroy.If the result is correct, perform step 303, otherwise provide the information that seal data have been tampered or have destroyed, process ends, cannot realize and affixing one's seal.
The numerical value of dynamic cell parameter can be obtained by attribute corresponding to this parameter, for example, to E-seal as shown in Figure 1A, the numerical value origin source limitation attribute of number parameter is obtained from specific memory device or server, and the numerical value origin source limitation attribute of time parameter is obtained from specific server; Property value corresponding to each parameter of seal dynamic cell determined according to actual conditions, for example, to E-seal as shown in Figure 1A, the property value of its numbering and date parameter has just been determined when chapter processed, here just do not need to have determined again, if but parameter attribute is such as color is only decided to be redness or black when the chapter processed, so now just need to determine: to the current chapter that will cover, this color attribute value is redness or black on earth.
In step 303; the identity (such as the use person's of affixing one's seal private key) that may further include the person of affixing one's seal after having determined the numerical value of seal dynamic cell parameter and the property value of parameter is to comprising dynamic cell parameter in the sign step of protection of interior seal data; but this step is not necessary, also can omit.
Complete seal data are kept in the document that need to affix one's seal, these complete seal data comprise the seal data of verifying by step 302 and the numerical value of dynamic cell parameter being obtained by step 303 and the property value of parameter, if also comprise the step that the seal data to comprising dynamic cell parameter are signed in step 303, these complete seal data also will comprise this signature result.
With the person's of affixing one's seal identity (such as the use person's of affixing one's seal private key) to the whole document that the comprises complete seal data protection of signing, thereby can not the distorting and the non-repudiation of the person's of affixing one's seal identity of the document of guaranteeing to be affixed one's seal.
The signature result of step 305 is kept in the document.
Three, the flow for displaying of E-seal
This flow process is to illustrate that user is after receiving the electronic document that is stamped E-seal, the flow for displaying of E-seal during opening document.
In this step, while showing seal, seal dynamic cell and static cell show in the same way, the dynamic cell that is seal does not have a first definite process showing again, this is all determined and no longer changed because of all parameters of seal dynamic cell when affixing one's seal and parameter attribute, and when affixing one's seal, be that the dynamic cell that the static cell of seal and seal have been decided is completely made the as a whole document that is recorded in, when opening the document demonstration seal of affixing one's seal later, seal just directly shows the data that are kept in document in a whole mode.
In a word, the foregoing is only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
