The intelligent secret keyboard is applicable to financial plate in banks, stock exchange, ATM, market... etc. has the vast market foreground.
Description
Technical field
The invention belongs to the computer equipment field, relate to electronic technology, specially refer to the changed randomly intelligent privacy keyboard of key assignments.
Background technology
At present, keyboard has become a kind of most important computer external input equipment.It not only can finish normal literal input, and as a kind of cipher input, has been widely used in fields of society, as: financial fields such as bank, stock market.
Yet as cipher input, the confidentiality of existing keyboard is relatively poor.Its main cause is that the key assignments of each key position of keyboard fixes, and such as general employed numeric keypad, the arrangement position of its numeral " 0-9 " the order whole world is unified, as Fig. 1.Such result is, the user is when the input password, and some prepared observers can analyze the password or the data of user's input by observing the user to the operation of each key position on the keyboard.Therefore, the stolen case of user's password is of common occurrence.Existing keyboard still can not change this situation by adding protective cover.Simultaneously, because the special circumstances of China, when the intensive occasion of bank, market or other personnel is carried out the password input, be difficult to guarantee effective secret distance, user's the right of privacy and property are subjected to great threat, impel quite a few people to be unwilling to use these class methods to conclude the business, influenced normal financial order greatly.
Therefore, study a kind of method for designing of new-type keyboard, can prevent financial crime, guarantee normal financial order, crucial social benefit and economic benefit are arranged.
Summary of the invention
The objective of the invention is: provide a kind of can be as required, the demonstration of the key assignments of random variation keyboard N (N represent keyboard portion or whole numbers of buttons) button puts in order and imports the method for designing of confidentiality to improve keyboard.
Realize that technical scheme of the present invention is:
One, the design of the importation of the key assignments display part of keyboard key-position and keyboard;
Two, to the design of the processing section of button input;
Three, the design of output interface part;
Four, the order that the display position of the key assignments of keyboard N (N represent keyboard portion or whole numbers of buttons) button is arranged is carried out the function of random variation, the design of the changed randomly intelligent privacy keyboard of realization key assignments.
1, the design of the importation of the key assignments display part of keyboard key-position and keyboard can be adopted the dynamically display device of each key position key assignments of display keyboard, such as other display devices such as LCD, CRT monitor, charactrons; Key assignments and button that key input part can be selected for use devices such as transparent push or transparent keyboard to cooperate and finish dynamic each button of display keyboard are imported two functions; Also can select the equipment that two functions are combined for use, such as: directly employing can be imported two functions with key assignments demonstration and keyboard that the touching-type monitor of numeral is finished keyboard by display graphics.
2, to the design of the processing section of button input, finish the key assignments that to be imported and convert computing machine or the needed code system of other peripherals to,, and finish processing capacities such as keyboard goes to tremble such as ASCII character or binary-coded decimal.
3, the design of output interface part, finish will input key assignments send computing machine or other peripherals to according to required electric interfaces and communications protocol, as the RS232 interface etc.
4, the order of the display position arrangement of the key assignments of keyboard N (N represent keyboard portion or whole numbers of buttons) button is carried out the function of random variation, realize the design of the changed randomly intelligent privacy keyboard of key assignments, be to finish this function, and N key assignments shown by program actuator or other digital-to-analog circuit.In this processing section, comprise following subfunction:
A) for the key position of the button of N on the keyboard, each key position is selected at random to the key assignments of first button after distributing a fixing keyboard physical location, just selects a key assignments as this button from N key assignments at random; Then, the key assignments of second button is selected at random, just from N-1 remaining key assignments, selected a key assignments at random as this button; The rest may be inferred, selects the key assignments of 1 remaining key assignments as this key until N button.As can be seen, this is the arrangement problems of a typical formation in the probability field, and its N key-value pair answers N the full arrangement of key bit position just to have
Kind.Here it is carries out random alignment to N key assignments formation, a kind of with in the full arrangement mode that obtains this N key assignments.
In order to finish this function, also have following two kinds of methods.A kind ofly be:, at first select a position at random as this key assignments from N key position from first key assignments of N key assignments; Then, second key assignments selected the position of a key position as this key assignments at random from N-1 remaining key position; And the like, select the position of last remaining key position until N key assignments as this key assignments, just a kind of with in the full arrangement mode that obtains a N key position of random alignment carried out in N key position formation, and with N key assignments formation and the formation of key position according to by left-to-right or by the order one by one corresponding demonstration of the right side to a left side, its principle is just the same with top method.
Another kind method is also similar: be exactly the arrangement of simultaneously N key position and N key assignments being carried out formation, and two formations that will obtain allow each key position directly show the key assignments that it is corresponding in N key assignments formation according to by left-to-right or corresponding one by one to the order on a left side by the right side; Vice versa, allows each key assignments in N the key assignments formation directly be presented on the key bits corresponding.Analyze a little, above-mentioned three kinds of methods as can be seen just, its principle is in full accord, and the function of being finished is also consistent, finishes the formation arrangement of N key-value pair being answered N key position exactly.
Be example below with the numeric keypad to the explanation that makes an explanation of these three methods.Earlier the physical location of 10 figure cases on keyboard being fixed up, be the physical location of these 10 buttons with the position of " 0-9 " key of traditional numeric keypad just here, and each key position is just represented with digital " 0-9 ", as Fig. 1.Arrange with first method: at first, " 0 " number key position is selected one totally 10 key assignments at random from " 0-9 ", supposes to select key assignments " 2 " here, and key assignments " 2 " is removed from the key assignments formation; Then, " 1 " number key position is selected in remaining 9 key assignments at random, supposes to have selected key assignments " 8 " here, and key assignments " 8 " is removed from the key assignments formation; The rest may be inferred, and " 2 " number key has been selected key assignments " 6 ", " 3 ", " 9 ", " 5 ", " 1 ", " 0 ", " 4 " respectively at random to " 8 " number key; Select last remaining key assignments " 7 " until " 9 " number key.Be equivalent to 10 key assignments " 0-9 " are carried out random alignment, this puts in order to have obtained " 2863951047 ", just these key assignments are put in order according to this then and and these 10 key bit positions " 0-9 " correspondence that puts in order, be presented at respectively on the physical location of key position " 0-9 ", as Fig. 2.
For second method, reason is just the same: promptly at first to key assignments " 0 ", select at random from 10 key positions, hypothesis has been selected key position " 7 " here, and key position " 7 " are got rid of from the formation of key position; Be key assignments " 1 " then, from 9 remaining key positions, select at random that hypothesis has been selected key position " 6 " here; The rest may be inferred, key assignments " 2-8 ", and then hypothesis has been selected key position " 0 ", " 3 ", " 8 ", " 5 ", " 2 ", " 9 ", " 1 " respectively at random; Then select remaining key position " 4 " until key assignments " 9 ", obtained " 7603852914 " this arrangement, and with key assignments from " 0-9' ' be presented at respectively on the key position " 7603852914 ", as Fig. 2.
For the third method, in fact with preceding two kinds also just the same: the key position of " 0-9 " 10 buttons is produced a formation at random arrange, the key position that produces of hypothesis is arranged as " 7456893210 " here; Also produce a formation at random for " 0-9 " 10 key assignments and arrange, be assumed to be " 0951473682 " here; Then with two formations according to by left-to-right or corresponding one by one to the order on a left side by the right side, select here by left-to-right order, what that is to say that " 7 " number key position shows is key assignments " 0 ", otherwise, key assignments " 0 " shows that in " 7 " number key position the rest may be inferred, display result such as Fig. 2.
By above-mentioned example, as can be seen, reason is just the same in fact for these three kinds of methods, and its result is also in full accord.Therefore, can select for use wherein a kind ofly arbitrarily, finish the function that changes button value display position on the keyboard.By to numerical key " 0-9 " key assignments of totally 10 key positions arrange, have the arrangement mode of 3628800 kinds of key assignments.Therefore, the key position that keyboard need change is many more, and its arrangement mode is also many more, and confidentiality is also just strong more.
B) under special circumstances, can finish more arrangement mode by increasing some redundant key positions, to reach higher confidentiality, as Fig. 3 and Fig. 4.In Fig. 3, increase by two redundant key positions, made the arrangement mode of 10 key assignments on 12 key positions increase
Kind, improved privacy degrees greatly.Therefore, behind M redundant key position of increase, total for the arrangement mode of N key assignments on N+M key position
Plant, reached the purpose of further raising confidentiality.
C) in addition, for the confidentiality that key assignments on the keyboard puts in order, a multifunction key or independent button need be set on each key position, such as " beginning " key.When the user brings into use keyboard, need press " beginning " key earlier, at this moment the program actuator of keyboard or digital-to-analog circuit will utilize top a) one of described three methods, finish the change that puts in order of each key assignments, and show on each key position.By the time after the user pressed " determining " key or " cancellation " key, the program actuator of keyboard or digital-to-analog circuit carried out randomly changing to putting in order of key assignments once more, the confidentiality that puts in order with the key assignments that guarantees keyboard.
D) at function c) in, after new key assignments of each generation puts in order, the program actuator of keyboard or digital-to-analog circuit can directly adopt, perhaps put in order or even a preceding x key assignments puts in order and compares with previous key assignments, put in order with the individual different key assignments of previous or even preceding x until producing one, and show for the user and use.
E) when the user imports, can be chosen in and just change putting in order of a key assignments after the user whenever presses one-touch, also can be chosen in and change putting in order of a key assignments after pressing button several times, or before user input data is finished, not change.Certainly, after putting in order of key assignments changed, put in order for new key assignments and will carry out function d) processing.
In sum, the changed randomly intelligent privacy keyboard of key assignments can guarantee to input the confidentiality of password and protection user's the right of privacy to greatest extent.
Effect of the present invention and benefit are:
By change, improved the confidentiality of keyboard greatly to the key assignments of each key position of keyboard.Because the key assignments of present each key position of keyboard is fixed, therefore the observer can obtain the physical location of operator each operated key position on keyboard by identification importer's input hand shape, and can finally obtain user's input password according to the key assignments of each key position on this keyboard.And the present invention is directly by changing the key assignments of each key position on the keyboard, and guarantees that can produce a kind of new key assignments when the importer brings into use puts in order at every turn, and use finish the back automatically change become another kind and put in order.Therefore, even the observer can obtain importer's the physical location to the key position of keyboard operation by identification importer's input hand shape, also can't obtain real input password, because the observer can't determine the key assignments of this key position.Because the keyboard of 10 numerical keys of common " 0-9 ", just have the arrangement mode of 3628800 kinds of key assignments, can also increase the arrangement mode of key position key assignments by the mode that increases redundant key position, to reach higher secret purpose.The present invention also can be by adding protective cover mode with the confidentiality of protecting password to greatest extent and protection importer's the right of privacy.
Therefore, the present invention can be widely used in the place that bank, cash machine, stock exchange, market etc. need the input passwords, can also be applied to special privacy device simultaneously, as cipher input of coded lock or the like.The present invention not only has very vast market prospect, and can protect normal financial order, and can play purposes such as preventing finance, criminal offense.
