The specific implementation of the present invention is disclosed in detail below with reference by several embodiments and accompanying drawing of the present invention：
Referring to Fig. 1, a kind of cryptographic check equipment of the present invention, including control unit 1, memory cell 5 and touch are aobvious Display screen 3.Described control unit 1 plays complete machine control action, is mainly used in performing and is realized according to the cryptographic check method of the present invention Program, so as to perform cryptographic check operation.Described memory cell 5, it is related to real to the cryptographic check method according to the present invention The permanently or temporarily storage of caused various intermediate data in the implementation procedure of existing program, for example, the preset password of user, Subsequently by caused candidate information unit, selected information unit collection etc. part or all, it may also be used in storage program The image, voice, state that are related to etc preset mark etc. is needed, those skilled in the art are it is to be understood that the side of the present invention The preset password of method and equipment need to permanently store (except it is non-resetting when change), whether entered as other data using the memory cell Row storage, for the method for the present invention, can flexibly be set by program, thus, for memory cell in the present invention Application, should not be construed as to the present invention relates to the restriction of memory technology.The cryptographic check method of the present invention, it is single in the control Under the scheduling of member 1, make full use of touch display screen 3 to realize man-machine interaction, or can also make in other embodiments common aobvious Display screen or touch display screen combination physical button, microphone, camera, infrared sensor, shock sensor, gyroscope etc. are realized Man-machine interaction, thereby, the cryptographic check operation of the present invention can be completed.
The facility subsequently illustrated for the present invention, if being preset with password in certain authenticating device, the password is believed by several Interest statement member, which sequentially concatenates, to be formed, and each information unit includes only a kind of information word, i.e. character information, for example, character string “1788”。
The method of the blurring verification password of the present invention, can be programmed realization by above equipment.Refer to below Flow chart shown in Fig. 2, and the please specific graphic user interface 80 presented by display screen 3 with reference to shown in Fig. 3.
In Fig. 3 of the present embodiment, the figure that is formed of first step as the method for the blurring verification password of the present invention Shape user interface 80, a particular display area 81 is shown, one group of candidate information unit is had in the viewing area 81, certainly These candidate information units can be arranged to multigroup, its group of number is only related to the facility journey of programming in the present embodiment Degree, the Spirit Essence that can flexibly set without influenceing the present embodiment.For the simplicity of description, by these occurred on display screen 3 Candidate information unit is considered as independent candidate information unit group.Described viewing area 81, can be on screen 3 in theory Region is arbitrarily designated, can be the border of screen in itself, any geometrical boundary can be not provided with, naturally it is also possible to as shown in Figure 5 For it, square boundary, or the border of other arbitrary shapes are set.
The corresponding candidate information unit group in the viewing area 81, all candidate information units in the group by by planning or Person randomly exports to be shown in the viewing area 81 with hashing.Candidate information unit group can include multiple information words, such as Character information member and color information member, are temporarily illustrated so that each candidate information unit group only includes character information member as an example.Often The information word of individual candidate information unit can totally 10 characters be formed by " 0 "-" 9 ", although in preset password only comprising " 1 ", The three kinds of information units in " 7 ", " 8 ", all candidate information units can then provide the other information unit of " 0 ", " 2 " ... etc, So as to strengthen the effect of its fuzzy expression.
Really, the information word particular content for the candidate information unit that candidate information unit group is included, also can flexibly change, Limited without character information in by the present embodiment.For example, the numerical character information word of candidate information unit can also be symbol, The information words such as English alphabet, icon.The type of information element of candidate information unit can also be not limited to character, can also be color The type of information element such as coloured silk, font, font size, pattern, image.For the needs of verification password, regardless of the candidate in candidate unit group How the information word content of information unit is set, and the information unit of the preset password should be incorporated into all candidate information units In at least one candidate information unit of group, the part or complete of the candidate information unit or the candidate information unit is formed Portion.For example, in order to verify the first password, its correct information unit should be character information member " 1 ", therefore, it is necessary to character " 1 " be wrapped Containing into wherein at least one candidate information unit, shown in the present embodiment Fig. 3,4 words are shown in graphic user interface 80 Accord with " 1 ", it is corresponding to be shown in viewing area 81, but position is mutually staggered.When preset password first place is first " 1 " only comprising character information When, then any one candidate information unit for including character " 1 " is the correct information unit of the first password, even if those are waited Information unit is selected also to include color information member so that four " 1 " are shown as red, green, blue, Huang Si kind colors on screen, this In the case of, " 1 " of any one color is selected, because candidate information unit corresponding to it contains character " 1 ", therefore should also regard the time Select the correct information unit that information unit is the first password.When preset password first place not only comprising character information first " 1 " but also When comprising color information member being " red ", then obviously, and if only if when have selected character " 1 " characterized with red, its institute Corresponding candidate information unit can just be considered as the correct information unit of the first preset password.
According to known password setting principle, in the candidate information unit, can both include each in the preset password The information unit of position sequence, is directly used these information units as candidate information unit, or the letter by these information units A part of the breath member as corresponding candidate information unit, can also or should include has with those preset password information units The other information unit of different information words.In the candidate information unit shown on screen, it is possibility to have multigroup that there is identical letter Cease the candidate information unit of member, on the one hand to strengthen the difficulty of decoding, on the one hand but can more convenient validated user password inspection Test.
In order to improve the difficulty for being spied on hypermnesia, before showing each candidate information unit every time, this can be treated The candidate information unit of display carries out random alignment, makes its disordering, and hash is finally exported in the viewing area 81 at interface 80 One group of candidate information unit.Thus, no matter user is the password for repeatedly inputting same position sequence, or in same password Multiple sequences character string multiple input, Peeping Tom is more difficult to remember entirety by the Rankine-Hugoniot relations of candidate information unit Layout, also just substantially increase Peeping Tom cracks difficulty.
In graphic user interface 80 shown in Fig. 3, several or all candidate information units on screen, in display screen On, such as arrange viewing area 81, then refered in particular in the range of its viewing area 81, carry out the motion of position real-time change.Each Candidate unit can both be moved in accordance with a certain formula for expressive movement track, in a manner of can also being changed at random by position Moved, can also be shown with the changeless static mode in position, it is ensured that the display position of all candidate information units Put and do not change.The scope of the viewing area 81 can be according to the display size and time of the information word of candidate information unit The number of information unit is selected to carry out appropriate constraint, it is same to ensure that these candidate information units do not focus on excessively as far as possible In concentrated area, only spend discrete.It is real with appropriate speed by the way that candidate information unit is designed as in viewing area 81 Now random drift, Peeping Tom are more difficult to remember simultaneously the content of multiple candidate information units of a certain concentrated area, therefore favorably In raising password cracking difficulty.Howsoever, the intersection of each candidate information unit is strengthened using known animation way of realization With reference to after reading this disclosure, should be those skilled in the art and work as understanding.
Continuing with combine Fig. 2 and Fig. 3, as the present invention blurring verification password method second step, it is necessary to realize User selectes to the ambiguity of target information unit coverage, namely realizes the ambiguityization expression of user's chosen content.Realize This ambiguity is selected, and in theory, can be showed by driving the target constituency 88 or the candidate information unit to realize On graphic user interface 80, it can desirably change target constituency 88 by user and the relative position of candidate information unit is closed System, to realize the setting of the relative position relation to target constituency 88 and candidate information unit, to determine that target constituency 88 is covered The number of the candidate information unit of lid reaches two or more.Set above-mentioned relative position relation, it is meant that Yong Huke With the appearance position by specifying target constituency 88 in real time, can also by changing the present position of known target constituency 88, or Change candidate information unit present position etc. mode to realize this setting, those skilled in the art should not be by its narrow definition Only to change known target constituency 88 or only changing candidate information unit present position to realize setting for this relative position relation It is fixed.
In the present embodiment, user can select the coverage in a target constituency 88 in several ways, but target is selected The relative position relation of area 88 and candidate information unit is arranged to be set on demand by user, and specific manifestation is finally true by user Set the goal the number of the candidate information unit that constituency 88 covered.These capped candidate information units, refer in particular to all Such as in the visualization plane of the graphic user interface 80 etc, fall into the target constituency 88 border and/or with the boundary-intersected Candidate information unit, regardless of whether those candidate information units belong to same candidate information unit group or different candidate informations Unit group.The border in target constituency 88 referred to herein, both include the outline of target constituency 88 showed by graphic plotting The visualization embodied sets border in fact, also includes not expressing and the void of its default physical extent in program with visual means If border；Both it had been included in the clear boundary that specific coordinate is specified in graphical interface of user 80, had also included in clear boundary On the basis of allow the ultimate bound that certain range of tolerable variance is extended or shunk.It should be noted that in order to realize the present invention Ambiguity expression effect, when selecting candidate information unit in the present invention, the letter of chosen (covering) can be specified by program The determination number of interest statement member, can not also specify determination number and be specified on demand by user, still, and if only if the target constituency 88 When covering two or more candidate information units, the necessary condition for selecting the target constituency 88 could be formed, from And realize to the selected of the target constituency 88.Be exemplified below it is several suitable for the present embodiment by sets target constituency 88 and candidate The relative position relation of information unit and realize selected method：
First, target constituency 88 and the method for selecting under candidate information unit simultaneously motion conditions.In this method for selecting, bag Include following steps：
(1) draw visual target constituency 88 and shown on graphic user interface 80, for example, Fig. 5 graphical user The target constituency 88 provided in interface 80 is a circle, and it, which has, is enough to cover the candidate information list shown at least three screen The radial dimension of member.The shape in target constituency 88 both can with rounded, certainly also can oval, square, polygon etc. it is various Rule or irregular shape, the outline coordinate in the target constituency 88 just constitute the border in the target constituency 88.Also, in pin When the verification carried out to some information unit in preset password starts, the target constituency 88 is i.e. with certain or variable speed Change its position and/or direction at random on graphic user interface 80 to realize the drift movement effects on interface 80.Need It is noted that the present invention is alleged to draw target constituency 88, wire expression as shown in Figure 3 is not limited to, can also be used all Such as color lump shade, figure layer shade, candidate information unit discoloration mode are realized, those skilled in the art should know this change It is logical.
(2) while keeping the target constituency 88 to do drift campaign, the candidate information list in the viewing area 81 Member also keep with the former similar or identical drift movement effects at random, its drift velocity can be flexibly true by those skilled in the art It is fixed, in order to which the candidate information unit that operator sees candidate information unit clearly and seen clearly into the target constituency 88 is defined, Implement finally selected user instruction so that user assigns in time.Understood with reference to step (1), (2), in target constituency 88 and candidate During information unit drift, target constituency 88 is natural to cover one or more candidate information units, because the present invention will It is that could form selected condition to seek the candidate information unit into target constituency 88 to have two or more, therefore, can With by the multiple candidate information unit of programming, always there is two or more candidate information units to carry out The adjacent focusing in position, this focusing refer to that these candidate information units are pre- less than or equal to some determination in physical distance If value.For example, a diameter of R in the circular target constituency 88 is set, if limiting any two neighboring candidate information unit Ultimate range be no more than R/3, then when target constituency 88 enter 81 middle part of particular display area when, just can easily simultaneously covering 3 Individual candidate information unit.All such examples, it can be realized easily by the spirit that those skilled in the art disclose according to the present invention.Thus may be used Can be that the graphic user interface 80 of the present invention sets the maximum of an acquiescence, the maximum of the acquiescence is described to understand The maximum lengthwise dimension in target constituency is with being intended to the ratio between selected candidate information unit number.In theory, the maximum of the acquiescence The maximum display size of graphic user interface is can even is that, such as the Diagonal Dimension of screen, and in practice then can be by ability Field technique personnel flexibly determine on demand, in practice generally in reference to upper example determine target constituency full-size and neighboring candidate information The relation of the distance of unit.Described default maximum, variable that both can be actual participate in specific calculating process, also can be by this Art personnel are silent in programming to be kept disclosed rule and realizes whether should not provide the acquiescence in plain text with program Value and to ignoring the presence of the default value.Stopped such as 0.5 second in other examples, if some position is arrived in target constituency manually Or after longer (short) time, candidate information unit can automatically move or transition to the target constituency in, it is clear that it is also replaceable The setting of the default maximum, those skilled in the art should know that this is flexible.
It should be noted that above-mentioned steps (1), (2) are not to refer in particular in time in two steps of precedence relationship, the above Two steps can parallel practice in time.
(3) user instruction for waiting user realizes final select.Specifically, user can be in the target constituency 88 When covering the candidate information unit of user's needs, a user instruction is triggered, realizes limit of the user to the position in target constituency 88 It is fixed, namely final setting is realized to the relative position relation of target constituency 88 and each candidate information unit, so as to also be achieved that The particular content of candidate information unit and the restriction of quantity that user is covered to target constituency 88.In the present invention, user instruction Triggering, for touch-screen 3, one can be considered as to the point selection operation of touch-screen arbitrary region or specific region with user User instruction, the user instruction is triggered when user touches screen, can also otherwise be realized, such as：Pass through camera Catch certain of some certain gestures of user or the visual horizontality for acting, user terminal being detected by gyroscope of some agreement Individual specific some special sound for manipulating, user being recognized by microphone instructs, recognizes user couple by shaking driver Rock, user is detected by infrared sensor certain gestures of terminal, by identifying one or more physical buttons It is in the conduction state etc., these touch-screens, camera, gyroscope, microphone, shock sensor, infrared sensor, physical button Etc. the input source (not shown) for constituting user instruction, user instruction is provided by these input sources to realize to the target constituency 88 it is selected.Once user defines the position in the target constituency 88, candidate's letter that the target constituency 88 can be utilized to be covered Interest statement member constructs a selected information unit collection.It should be noted that the selected information unit collection alleged by the present invention, refer to by The data set that multiple chosen candidate information units slap together, it is of course possible to data are carried out in the form of mathematical set concept Tissue, but be not construed as being only capable of being subject to data tissue with the set on mathematical concept.No matter by computer data structure Aggregate form is realized or realized with multiple simple variables in computer data structure, is regarded as not unconventional The Spirit Essence of invention.
2nd, candidate information unit is motionless and method for selecting under the motion conditions of target constituency 88.In this method for selecting, bag Include following steps：
(1) in a manner of with the first method for selecting identical, described target constituency 88 is drawn, and similarly make the mesh Mark constituency 88 carries out drift campaign on screen.
(2) it is different from the first method for selecting, in this method, all candidate information units are in its corresponding viewing area The scheme of the foregoing changeless static state display state in holding position referred to is used in domain 81.When the drift of target constituency 88 During motion, because candidate information unit remains stationary is motionless, a clearer graphic user interface 80 is may provide the user with, Be advantageous to the accurate operation of validated user.Certainly, in this case, ambiguity expression effect can be caused to decrease.With candidate The scheme identical that information unit carries out drift campaign is, it should be noted that with reference to foregoing mode, processing sets the target constituency Relation between 88 size and the distance of the candidate information unit of arbitrary neighborhood, it is ensured that target constituency 88 enters candidate information list First metapedes of viewing area 81 is to cover two or more candidate information units of static display simultaneously.
(3) realized using the method similar with the first method for selecting to the selected of target constituency 88, i.e., when target constituency During the candidate information unit that 88 drifts are wanted to covering user, target constituency 88 can be limited by a foregoing user instruction Position, relative position relation between target constituency 88 and at least part candidate information unit is determined, and determine the selected information Unit collection.
3rd, target constituency 88 is motionless and method for selecting in the case of candidate information unit motion.
Referring to Fig. 4, the graphic user interface 80 shown in Fig. 4 discloses the He of target constituency 88 that this method for selecting is applicable The layout that candidate information unit is formed.In this method, with reference to the first method for selecting, equally include three steps, however, its In (1) step, the position of the target constituency 88 drawn in graphical interface of user 80 is changeless, and Fig. 4 is by target The position in constituency 88 is fixed on screen center, and in (2) step, candidate information unit is then consistent with the first method for selecting, The scheme moved using candidate information unit, thus, in (3) step, when there is several candidate information units Drift is in target constituency 88, and when reaching the desired state of user, i.e., there are several candidate information lists in the target constituency 88 First and one of candidate information unit includes the information word that user wants, in this case, as long as user assigns described use Family instructs, you can determines the selected information unit collection under current state.
4th, the method for selecting under the passive situation of target constituency 88.In this method, comprise the following steps：
(1) target constituency 88 is drawn in manner previously described, it is ensured that the area in the target constituency 88 is enough to cover two Or more than two candidate information units.The initial position of 88 1 determinations in the target constituency is assigned, such as shown in Fig. 3, is stopped In the bottom of graphic user interface 80.
(2) it is used as input source (not shown), such as camera, touch-screen, gyroscope etc. by one of various input equipments Corresponding detecting user gesture, the touch control operation of user, user carry out horizontal control to authenticating device, and input is started with user When source performs above-mentioned artificial action, input source triggers first time user instruction, drives the target constituency 88 independently to be transported It is dynamic or continued by user action (corresponding such as continuously visually, continuously referring to and draw, continuously tilt authenticating device) And drive, change until user chooses the desired position of target constituency 88 (for instance in the target constituency position shown in Fig. 4) It is artificially acted.
(3) when user changes its artificial action, such as corresponding above-mentioned each input source can show as user to blink, remove From finger, stop tilting authenticating device etc., now input source triggers second of user instruction, the position residing for current goal constituency 88 Put and be just designated, at this moment, all candidate information units that target constituency 88 is covered can form described selected information unit Collection.
In this method for selecting, it is that the motion state variable in position is in position that can not consider candidate information unit Put changeless inactive state.
5th, the method for selecting under candidate information unit passive situation.In this method, comprise the following steps：
As the application of equivalent substitution, provided in advance in the above listed target constituency 88 of the present embodiment, non-dynamic generation Method for selecting in, no matter whether position is fixed or position dynamic change for candidate information unit, no matter target constituency 88 Whether it is kept in motion, can be in step (3) using the driving target constituency 88 as described in the 4th kind of method for selecting Mode receive the first user instruction, can drag and drop multiple candidate information lists successively under the driving of first user instruction Member, candidate information unit is additionally related to multi-functional passive entry described target constituency 88, thus, can similarly realize target constituency 88 to multiple times Select the covering of information unit.In this case, for the 4th kind of method for selecting, user not only can be by controlling candidate to believe The position of interest statement member, and can be by the position in control targe constituency 88, to realize candidate information unit and target constituency 88 The setting of relative position relation.
6th, the method for selecting in the case of the dynamic generation of target constituency 88.
As shown in figure 5, this method be easier to it is manually operated.Specifically, it is referred to shown in the first method for selecting, makes Candidate information unit holding in viewing area 81 either statically or dynamically shows that user selectes to the target area, by using One refers to a stroke operation generation caused by family.No matter whether the viewing area 81 and its interior candidate information unit move, as long as with See clearly desired candidate information unit in family, you can multiple candidate information units are streaked by finger, and ensure that this refers to stroke work The selection area scope formed passes through the candidate information unit that user wants, and program limits and makees to be formed when this refers to stroke Selection area by two or two with candidate information unit when, be just considered as user and be made that once effective to draw choosing dynamic Make, construct target constituency 88 based on this.When user's finger starts stroke, it is considered as user and triggers the first user instruction； When user's finger, which continues stroke, finally to frame out, equivalent to discharging or complete the user instruction, or it is considered as user's triggering Second event, that is, form second user instruction.How first instruction and second instruction are distinguished, can be flexibly real by programmer It is existing, do not influence the fact that user is autonomously formed target constituency 88 because of this division.From the first user instruction to second user Instruction, the selection area just formed, it is well known that formed selection area is drawn by the finger of user, it is not definitely accurate , but certain range of tolerable variance is contained, thus, user produces the target constituency 88 by referring to draw and dynamic, and with Candidate information unit in the range of the target constituency 88 covers determines the selected information unit collection, in itself with it is foregoing Various method for selecting belong to same inventive principle, without unconventional Spirit Essence of the invention.Mesh is determined it should be noted that referring to and drawing Constituency 88 is marked, due to multiple user instructions can be construed to, therefore there must be a final instruction (second user instruction), it is final by this Instruction produces specifies to the last of the present position of target constituency 88, is also achieved that target constituency 88 and the phase of candidate information unit Setting to position relationship.The scope that user draws choosing is broader, may more cover multiple candidate information units in theory, and this When, if program defines most candidate information unit numbers, it is contemplated that before intercepting the initiation region of target constituency 88 Several candidate information units are effective selected information unit collection, remaining unnecessary candidate information unit just constitute interference because Element, the ambiguity expression effect of the present invention can be strengthened.
Graphic user interface 80 shown in Fig. 5 discloses the utilization effect of this method for selecting, is given on interface 80 up and down Two consistent keyboard layouts.The keyboard layout of top, it is assumed that it is used for the first school for realizing foregoing preset password " 1788 " Test, then user can construct corresponding selected information unit collection by the selected character " 6 " of finger stroke, " 7 ", " 1 ".The keyboard cloth of lower section Office, it is assumed that it is used for the deputy verification for realizing foregoing preset password " 1788 ", then user by refer to draw a selected character " 7 ", " 3 ", " 1 " can construct corresponding selected information unit collection.Certainly, multiple keyboard layouts are provided on same graphic user interface Simply to illustrate that the convenience of multidigit cryptographic check, should not be construed as limiting the invention, those skilled in the art should When knowing, a graphic user interface 80 can be realized only with a keyboard layout.
Execution refer to draw operation when, the target constituency can be both shown in a manner of visual on screen, can not also be shown The target constituency, the candidate information unit that the former selectes user is more directly perceived, so as to strengthen interactivity；The latter then makes it more To be hidden, enhancing confidentiality.
Certainly, work is rowed to realize this dynamic generation mesh although preferably performing to refer on the touch screen 3 in this method for selecting The scheme in constituency 88 is marked, is set if those skilled in the art still should be appreciated that by a hanging gesture operation, can also be same Sample is construed to one by camera or infrared sensor and draws similar user instruction collection with referring to, so as to realize similar selection area Effect.Similarly, replacement means that are visual, tilting screen etc can also be entered by those skilled in the art according to this method for selecting Row is realized.
Above a variety of typical target constituency 88 method for selecting are listed for the present embodiment.Those skilled in the art should know Dawn, the spirit instructed by the example of the present invention, and a variety of input sources (not shown) disclosed, with reference to people in the art Cognition of the member to conventional techniques, can become and dissolve the diversified restriction method of target constituency 88.No matter target constituency 88 It is to be drawn by program previously given, or is specified in real time by user in checking procedure, be the Spirit Essence institute of the present invention The zone of reasonableness that should be included.
It is to realize verification as the step of key the 3rd of the method for present invention blurring verification password please continue to refer to Fig. 2 It is crucial.In the present embodiment, selected information unit collection is obtained via the first two steps, therefore this step is mainly to selected information The further utilization of unit collection.After this step obtains selected information unit collection, by the information of the position sequence to be verified in preset password Unit is compared with the selected information unit collection, when selected information unit collection includes described information unit, you can it is determined that with Family have selected the correct information unit in preset password, namely user correctly have selected it is identical with the information unit in preset password Content, verify successfully.
Need to be illustrated, if preset password is stored in this terminal (equipment), should transfer in memory Preset password is used for above-mentioned verification, if preset password is stored in distal end, can be sent to selected information unit collection accordingly Distal end perform this verification, finally return to whether verify successful feedback result by far-end server.
In addition, the candidate information unit shown in the present embodiment and the information unit in preset password, for the easy of statement It is reduced to only include single information word, therefore, can when information unit in preset password is compared with selected information unit collection So that the element of the information unit in preset password and selected information unit collection is carried out into congruent comparison.However, once being addressed as preceding, wait Information unit is selected to include multiple information words, for example, setting corresponding to first preset password " 1 ", the viewing area shown in Fig. 4 In 81, four characters " 1 " are expressed with red, green, blue, Huang respectively, namely four character " 1 " institutes corresponding in viewing area 81 The candidate information unit of category, two information words substantially are included, one is character information, secondly be color information, character information Expression is carried out with color information and is formed secure bond.Certainly, two information words can also one be pattern or image, another is word Symbol, pattern (image) can be the shapes of square frame or circle etc, can be by character when two information words carry out Visualization (image) is set in pattern or circle and shown.Two information words can also be the card formula of such as red heart, plum blossom, spade etc Pattern and some subject images, can be by a pattern and an image close to display when carrying out Visualization.It is foregoing to be In the preset password for simplifying description and setting, only with unique information word of the single character information as its information unit, this In the case of kind, the information word of the information unit in preset password is the whole of the information unit, the information list in preset password When member is compared with selected information unit collection, it is impossible to by the information unit (or its information word) in preset password and selected letter The element of interest statement metaset carries out directly congruence and compared, and should be by the information unit (or its information word) in preset password and choosing The each information word for determining the element of information unit collection is compared, that is, by information unit (or its information in preset password Member) enter row set in itself with the element of selected information unit collection compared with.In this case, as long as verifying to the letter in preset password In some information word, namely preset password of some element that interest statement member (or its information word) is congruent to selected information unit collection Information unit (or its information word) be contained in some element of selected information unit collection, that is, should determine that user have selected Correct information unit in preset password.The congruence (in) of information word alleged by the present invention, refers to the information unit in preset password Certain information word and selected information unit collection some information unit in some information word between, both have identical Content；The congruence (in) of information unit alleged by the present invention, refer to information unit and selected information unit collection in preset password In both some information units there is identical information word.
Thus the information unit suitable for preset password further extended includes two and more than two information words Embodiment in.Concrete example set as：If the preset password of certain authenticating device is sequentially concatenated by several information units and formed, each Information unit includes two kinds of information words, is character information respectively, and for expressing the color information of character color, for example, Green character " 1 ", red glyphs " 7 ", yellow character " 8 ", green character " 8 ".In principle, user is carried out close using authenticating device During code check, it is impossible to by simply inputting the character string " 1788 " without color characteristics to decrypt, but need sequentially to choose each The character of correct color, forms the correct characters that each position is respectively provided with correct color characteristics, could form whole correct information lists Member, it can just be considered as whole string cryptographic check success.In the third step for showing the present invention, in each of relatively preset password , it is necessary to each element that all information words of the information unit in preset password and selected information unit are concentrated during information unit All information words compared one by one, each information word of the information unit in and if only if preset password is belonged to or is equal to During the corresponding information member for the information unit that selected information unit is concentrated, just determine that user have selected preset password corresponding positions sequence just True information unit.
In order to further enhance blur effect, in above candidate information unit has the variation instance of multiple information words, Two or more candidate information units can be chosen, or believe in different candidates in same candidate information unit group In interest statement tuple, one or more candidate information units are respectively selected, make multiple such candidate information units at least have same Identical information word, for example, corresponding to the preset password " 1788 " for only including single information word previously with regard to information unit In character " 1 " exemplified by, four characters " 1 " shown in Fig. 3 can be made respectively with red, green, blue, yellow or in corresponding color lump In shown, or make the discrete character in several positions shown in Fig. 3 be shown using same color, thus, Peeping Tom It not only should be noted that the difference of character information, it is also noted that to the difference of color information, necessarily it is made to a certain extent Into obscuring.Obviously, when this variation instance is combined with the preset password that information unit has two kinds and two or more information words When, it can more highlight its ambiguity expression effect.Specifically, if if information element content is red character in preset password " 1 ", and set and the different character " 1 " of four display colors is included in the viewing area 81 shown in Fig. 3, in this case, by Character content " 1 " and the color characteristics selected by user must be remembered simultaneously in Peeping Tom, even if Peeping Tom repeatedly observes, by institute The content increase that need to be remembered, can also substantially reduce its hypermnesia effect.
As can be seen that by being arranged to described candidate information unit to include two or more information words, can To further enhance the expression of the ambiguityization of candidate information unit, namely the ambiguity of enhancing user's chosen content, user are difficult to lead to Cross and spy on hypermnesia or transcription is peeped and the mode such as looks into follow-up decryption, even if by way of data intercept stream, due to same choosing Determine information unit concentration and multiple chosen candidate information units be present, and also exist in same chosen candidate information unit Multiple information words, Data acquisition person to crack difficulty still higher, therefore, comprising multiple information words in candidate information unit Mode, the occasion of remote password verification is more suitable for, can be used for WiFi cryptographic checks, webpage cryptographic check etc..
Above in a kind of exemplary embodiment of the method for blurring verification password, both considered residing for candidate information unit The situation that position is fixed, it is also considered that the situation of candidate information unit Dynamic Announce in particular display area 81.It should be noted , this case of motion is mainly to be confined to be shown in the range of particular display area 81 by candidate information unit, therefore its Range of movement limited degree is higher.The viewing area 81 can actually expand to the whole size of user interface 80, should not be with display The illusory or real of region 81 sets border to limit the present invention.Random walk shows this permission candidate information unit in a wider context The scheme shown, the Dynamic Announce effect of the present invention is further liberated, would be even more beneficial to design more dynamic man-machine Interactive interface.
It is emphasized that the viewing area 81 of the candidate information unit can be designed as arbitrary shape, the target The forms of motion in constituency 88 can also be done appropriate adjustment by those skilled in the art, because shape and motion mode are difficult to exhaustion, be Length is saved, is not repeated for this reason.
A kind of typical embodiment of the method for present invention blurring verification password is disclosed in detail above, while is also given Some the general technology details gone out in the present invention.The method of inspection above is mainly for the independent position sequence in preset password Information unit is described, and corresponds to that foregoing several multidigit cryptographic check methods are further to be quoted below：
In the first multidigit cryptographic check method, can sequentially it be applicable according to multiple information units in preset password The method of the blurring verification password of the present invention verifies to each information unit of preset password, when it is determined that user have selected During all correct information units, feed back as a result, output characterizes whole preset password and verifies successful information, there is provided to follow-up Program uses, such as the program available for execution unlocking, program available for execution subsequent operation etc..This mode is comparatively Tradition, widely use, most typical application is in the unlocking screen for mobile terminal, it can also be used to the cryptographic check of ATM With webpage cryptographic check etc., it is it will be understood by those skilled in the art that so need not repeat.
Second of multidigit cryptographic check method, for previous embodiment, is referred to shown in Fig. 5, the top keyboard that Fig. 5 is provided In layout, suitably it is carried out using the 6th kind of method for selecting of target constituency 88 in previous embodiment.Specifically, performing During the second step of the method for present invention blurring verification password, it is allowed to which user is selected using the 6th kind of foregoing target constituency 88 Mode corresponds to multiple information units in preset password and disposable successively selected multiple target constituencies 88, and is performing the present invention , then can be according to the sequence of positions of preset password information contained unit, one by one when being blurred the third step of the method for verification password Accordingly, the selected information unit collection each target constituency 88 constructed and the information list of the relevant position in the preset password Member is verified, when sequence certain corresponding target constituency 88 in position has the information unit that corresponding positions sequence is included in the preset password When, as user have selected the correct information unit in the preset password, that is to say, that when all information lists in preset password Member is respectively corresponded when include by the selected information unit collection corresponding to each target constituency 88, the whole school for going here and there preset password The work(that accomplishes is tested, can be exported and be characterized the whole string successful signal of cryptographic check and be easy to perform subsequent action.
The third multidigit cryptographic check method is the improvement made on the basis of second of multidigit cryptographic check method, two The difference of person is only in that, in second of multidigit cryptographic check method, is emphasized suitable according to the arrangement of information unit in preset password Sequence, verified correspondingly compared with the selected information unit collection corresponding to the target constituency 88 selected with priority, and the 3rd In kind multidigit cryptographic check method, then this order need not be particular about, but when selected corresponding to any one target constituency 88 When information unit concentration includes any one information unit in preset password, you can be considered as the selected information unit collection and contain The correct information unit of this sequence of preset password.Obviously, this method reduces the complexity of code breaking, its security phase To reducing, but hardware requirement is necessarily reduced, therefore be suitable for application in some using only in the verification occasion of chip microcontroller.
The top of graphic user interface 80 disclosed in Fig. 3, Fig. 4 and Fig. 5, some circles are presented and punctuate 84, it is pre- for indicating If the verification state of the multi-bit information unit of password, belongs to conventional design well-known to those skilled in the art, does not repeat for this reason.
In any of the above multidigit cryptographic check method, in order to increase complexity, it may be considered that further arrange every information Unit verified before the quantity of candidate information unit that is covered of target constituency 88, and ensure that this quantity is equal.This Kind in the case of, for preset password every information unit and, have the selected information unit collection of fixed element number right therewith Should, improve computation complexity naturally, be less susceptible to by by spy on hypermnesia or transcription peep look into etc. in a manner of decoded.
In summary, although the present invention illustrates in form according to two embodiments, actually contains numerous and diverse A variety of variants, it is seen then that according to the method for the blurring verification password of the present invention, can be constructed by those skilled in the art a variety of Various programming process, being consequently formed diversified graphic user interface has man-machine interaction schemes.By the mould of the present invention Be gelatinized verification password method realize cryptographic check design, taken into account in plain text expression ambiguity and user operation it is easy-to-use Property, there is the characteristics of safe and reliable.
It is emphasized that programming can be presented various because of factors such as program language difference, personal style differences Change, thus, above-mentioned two checking procedure examples, it is intended to cast a brick to attract jade, should not be construed as limiting the invention.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies Within, then the present invention is also intended to comprising including these changes and modification.
