Abstract
The invention relates to an anti-peeping password input mode and relates to the technical field of information technology. The anti-peeping password input mode is particularly suitable for the occasions where a password needs to be input in daily life. The anti-peeping effect during password input on public occasions is achieved through the mode of combining a technology of randomly changing character key positions and an orientation display technology. The orientation display technology makes a person other than a password inputting person fail to see character contents displayed on a keyboard; after the mode of randomly changing the character key positions is adopted, even if the person other than the password inputting person can see key motions of the password inputting person, he cannot judge what input characters are. Therefore, the anti-peeping effect on the public occasions can be achieved. The anti-peeping password input mode is suitable for public occasions needing password input, such as a bank counter device, an automatic teller machine (ATM) and a point of sale (POS) machine, the person other than the password inputting person can be prevented from peeping the input password, so that user's personal information security is protected, and individual privacy is effectively protected.
Description
Technical field
The present invention relates to areas of information technology, particularly to needing when carrying out Password Input in public to prevent from being peeped to the situation of personal identification number.
Background technology
The position that character " 0-9 " on the cipher inputting keyboard of the existing bank card POS, ATM, banking terminal machine, POS and other equipment arranges is fixing, general people except Password Input person except remotely can according to input password time gesture or the position of button, peep or judge the encrypted message inputted.Additionally, in order to prevent being peeped password when inputting password by the people except Password Input person, now commonly used method is to install various radical occlusion device on cipher input, to block the sight line of the people except Password Input person, but, such device also blocks the sight line of operator simultaneously, causes very big inconvenience, and confidentiality is poor and very impracticable.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of anti-peeping password input mode, can block the sight line of people except Password Input person, the sight line of the person that simultaneously do not interfere with Password Input again.And, even if the people except Password Input person is it can be seen that the position of the action of hand of Password Input person and button, the character content of its input also cannot be judged.Thus when realizing needing to carry out Password Input in public, effectively preventing from being peeped password by the people except Password Input person, ensureing the safety of personal finance and other information.
For solving the problems referred to above, a set of technical scheme that the present invention adopts is: can change character key mapping technology at random and directed Display Technique combines.
Described directed Display Technique is, looks technology with aobvious with the orientation being perpendicular to visual angle, keyboard face zero (or close to zero visual angle) direction, makes the content on cipher input cast out with the direction being perpendicular to keyboard face.Password Input person is when inputting password, only very narrow on the direction be perpendicular to input equipment region, just can see in input equipment the key mapping character of display, and the people except Password Input person, then it cannot be directly viewed the key mapping character shown on cipher input.
Described directed Display Technique, can be realized by various ways in different conditions and application.In microelectronic engineering design application, it is possible to adopt the liquid crystal aligning display screen by different know-why designs to realize；In large-sized engineering design application, it is possible to realize by a kind of traditional " thick key " structure.Such as Fig. 2, the character of each figure of eight is constituted (such as Fig. 3) by multiple point sources (such as light emitting diode), each point source is the light pipe that a root bottom part is luminous, the light that character shows " body " feather key panel surface by light pipe, light penetrates (such as Fig. 3) with the direction being approximately perpendicular to surface of keyboard.So, just only vertical " faced by " people of keyboard just can see the content of keypad character.
Described can change character key mapping technology at random, sets 12 key mappings (3 × 4) on cipher input, wherein has " deletion " key, " confirmation " key, also has " 0-9 " 10 character keys (see figure 1)s.The key mapping order of these 10 character keys is all random display each time, the person that thus can ensure that Password Input is when inputting password, even if the people except himself sees the finger of importer by which key mapping, what also do not know that he inputs is which character in " 0-9 " on earth.Other key mappings can be set up as required, but these 12 key mappings are the necessary key mappings when inputting " 0-9 " numerical ciphers.
The described display mode that can change character key mapping at random, can be realized by various ways or technology in different applications.Independent cipher input equipment can adopt software programming produce stochastic signal, then be shown that " 0-9 " realizes respectively by ten key mappings of stochastic signal control；Entire display screen can also adopt the character that software programming controls on dummy keyboard carry out random display.

Detailed description of the invention
Some different embodiments adopt different forms but have the device of identical function to realize the function of the present invention.For simplicity, the device in this each embodiment is illustrated the same functional device being equivalently applied in other embodiments.It addition, for clarity, the figure of the apparatus embodiments illustrating display only illustrates one part, and actually this device is to be connected with the device such as bank's cabinet face computer operating system, the network system of ATM and the system etc. of POS that need input password.
When computer or network system require that user inputs password, 10 character key mappings on the cipher input (Fig. 5) of " random change character key mapping technology " are adopted to automatically update, display " 0-9 " respectively.
At this moment, what adopt due to this keyboard is directed Display Technique, so, only the operator on the direction of visual lines perpendicular with keyboard face just can see clearly the character content in key mapping, can't see character in key mapping in other angles.The head of operator must be just to see clearly the character on keyboard in the surface of keyboard, and the people beyond Password Input person cannot " be extruded into " on the direction vertical with keyboard face certainly.So, the actuation of keys of the people beyond Password Input person can only see Password Input person and button key mapping, but cannot know what the password that he inputs is on earth.
When input, often one code characters of input, all can show one " * " number on a display screen, this mainly allow operator judge whether actuation of keys effective, namely pressed after key either with or without input character.It is defeated that backspace weight is used as in the effect of " amendment " key when inputing character by mistake.After Password Input completes, operator presses " confirmation " key and just can confirm that Password Input terminates.
In above-described embodiment, the surface coat of cipher input and button are metal, plastics or other fixing materials, directed Display Technique adopts ordinary optical structural principle " leaded light " to realize the directed projection of light, as long as actually we can adopt all to be capable of the device of directed display (such as utilizing the orientation display liquid crystal display screen etc. that light polarization principle or other guide-lighting principle design manufacture), certainly, the display mode that can change character key mapping at random also has and can come real by various ways.
In a word, orientation Display Technique and key mapping character random alignment technology are combined closely by the present invention, person is just visible to make key mapping random character only have Password Input, it is better than the wide variety of way installing shutter at code keypad now, thus preventing the function peeped when have effectively achieved Password Input in public.
If it addition, directed Display Technique is used in a design of the small screen display device need to checked by individual, the equally possible peep-proof function realizing individual's use equipment.Such as, if Mobile phone screen adopts directed Display Technique, it is possible to when preventing from using in public mobile phone, content on screen is peeped by other people.And, the display device of such directed display peep-proof screen mobile phone or other employing smaller screens, have at least two benefits: one is power saving, because the power consumption of directed display screen can reduce a lot；Two individual privacies when being can conscientiously protect mobile phone to use in public, even if face-to-face with others, the other side also can't see the content that your mobile phone screen shows.
Certainly; the present invention can also have other various embodiments; without departing from the spirit and substance of the case in the present invention; those of ordinary skill in the art should make various embodiment according to the present invention, but these corresponding embodiments all should belong to the scope of the claims appended by the present invention.
Industrial usability
The present invention can replace in the device design that existing bank's cabinet face Password Input, ATM Password Input and POS Password Input etc. be there is a need to prevent others from peeping when Password Input comprehensively.Wherein, directed Display Technique also can be widely used in the small display design that mobile phone etc. needs peep-proof.
