Description

Completely shadowing peep-preventing cipher keyboard and cipher-code input method thereof

Technical field

The novel peep-preventing cipher keyboard that keyboard and hand motion can cover fully when the present invention relates to a kind of input the, and a kind of new cipher-code input method.

Background technology

In the advanced information society, numerical ciphers more and more is applied among the various safety precautionss.For example, bank counter and ATM withdraw the money, market POS machine bankcard consumption, security exchange, coded lock etc., all are to utilize numerical ciphers to guarantee user's legitimacy.In theory, numerical ciphers can provide very high user security, but because the existing password input equipment, the defective of code keypad for example, and the safety of numerical ciphers itself but can't be protected.Except that closely peeping, offender who has even the hand motion when can be beyond several meters import according to user's keyboard be judged password, and cause the case of property loss to happen occasionally by the leakage password.The lawless person is that the technical ability of training that snatches password improves constantly, and instrument that is adopted and means are also advanced day by day, for example utilize telescope, camera to come snooping password, even took place the offender to utilize video camera wide-long shot user ATM operation and the case that snatches password.The malice password is spied on the safety that digital cryptographic system in serious threat, is threatening citizen's property and personal safety.On the other hand, the insecurity of cipher input equipment has also limited the range of application of digital cryptographic system greatly, and for example, up to now, number coded door lock can't be applied to family security door always.

For improving the security of cipher input equipment, the improvement project of some code keypads has appearred.Investigate as can be known; in these schemes, most improvement thinking is to reduce the visual angle by covering or limiting light path, makes that the password input action is difficult to observe; thereby reach the purpose of cryptoguard, for example the scheme of announcements such as CN1570835A, CN1177764A, CN2530298.Therefore the problem of this class scheme is, can't cover the password input action fully, or can cover input action, but can't cover the password of input, can't prevent fully that malice from peeping, and its security can not obtain just protecting.In addition, the keyboard that reduces certainly will give to adopt this class scheme in the visual angle brings difficulty installing, and this class code keypad of user's use also will inevitably be subjected to the influence of its health natural conditions such as height, eyesight etc. and inconvenience is arranged more.On the other hand, these known scheme ubiquity equipment complexity, the shortcoming high to environmental requirement do not possess the ability of anti-accident or malicious sabotage, thus can't be applied to comparatively abominable workplace, for example can't be on family security door reliably working.

Summary of the invention

Investigate the basic reason that password can be spied on, the existing password input equipment needs vision and hand motion to participate in simultaneously just finishing input, so its input process can not be covered fully, so also must be spied on.Participate in if need not vision when the user inputs password, just can realize covering fully of input action, it is impossible fundamentally to make password spy on to become.From this principle, the present invention provides a kind of code keypad and cipher-code input method thereof that vision participates in finishing the numeral input that need not, and has got rid of the possibility that password is spied on fully.

Among the present invention, the principle of code keypad as shown in Figure 1.The importation of code keypad is provided with two numerical keys and two function keys totally four buttons.Numerical key is respectively＜and 1 〉,＜3, the combination of these two buttons can be finished the setting of numeral; Function key is＜import and＜remove,＜input〉function be to confirm correct operation,＜remove key then cancels faulty operation, on these two buttons and the existing code keypad＜input,＜removing the key function is identical.Compare with existing code keypad, the button of importation is by 12 (numerical key 0-9, function key＜input 〉,＜remove) tapered to 4, the complicacy of keyboard structure reduces greatly, and even more important a bit be, because button has only 4, so by the ergonomic designs of keyboard shape and the reasonable arrangement of key position, when the user carries out the password input operation, its finger and button particularly numerical key form the relation of contraposition one to one, when importer's hand places when being in the nature extended configuration on the keyboard, forefinger is pressed will be by arriving＜1〉key, middle finger is pressed will be by arriving＜3〉key, the importer need not to see keyboard just can know own by be what key, need not vision and participate in, the importer just can finish the input of password, so just can utilize mask to cover button and importer's finger movement fully and do not influence its input operation, fundamentally eliminate the possibility that password is spied on.The cipher-code input method of code keypad is as described below:

The numeral of input is at every turn from waiting for that input state is to pressing＜confirming〉result that draws according to certain regular computing of the numeral of the preceding numerical key representative of being pressed of key.A kind of effective input rule is as follows:

The numeral of being imported for from wait for input state to by＜confirm the numerical key representative numeral pressed before the key and, numeral ' 0 ' is by 10 representatives, button and surpass 10 in error code.For example, if input digit ' 5 ', then can be by＜3〉key 1 time,＜1〉key 2 time, then by＜confirm key gets final product, the button order does not influence input results; If input digit＜0 〉, then by＜3〉key 3 times,＜1〉key 1 time; Numeral may not only a kind of input method, for example wants input digit ' 5 ', also can press＜1 continuously〉key 5 times then by＜confirm key; When inputing one group of password, only need import each numeral successively as stated above get final product＜cancellation key can remove the input of mistake.Following table has provided a kind of input method of digital 0-9.In finishing password, during the input of last bit digital, can press once more＜confirm key finishes the input of password.

Input digit	Input method
		0	＜3 〉+＜3 〉+＜3 〉+＜1 〉+＜confirm
1	＜1 〉+＜confirm＜confirm
		2	＜1 〉+＜1 〉+＜confirm
3	＜3 〉+＜confirm
		4	＜1 〉+＜3 〉+＜confirm
5	＜1 〉+＜1 〉+＜3 〉+＜confirm
		6	＜3 〉+＜3 〉+＜confirm
7	＜1 〉+＜3 〉+＜3 〉+＜confirm
		8	＜1 〉+＜1 〉+＜3 〉+＜3 〉+＜confirm
9	＜3 〉+＜3 〉+＜3 〉+＜confirm

Among the present invention, the structure uniqueness of code keypad has following characteristics:

1) setting of all numerals of 0-9 only needs 2 numerical keys, only need 4 buttons can finish all input operations, because number of keys is few, therefore by the ergonomic designs of keyboard profile and the reasonable arrangement of key position, can be easy to accomplish finger and button contraposition one to one relation, the user does not need to see that keyboard just can know that what key what press is, finish the password input, therefore can utilize mask to realize covering fully of button and hand input action, fundamentally eliminate the possibility of using any method snooping password.

2) keyboard structure is simple, and can realize covering fully, if adopt strong but pliable in texture material mask, then mask has just had safeguard function concurrently, so just greatly improved the anti-damage ability of keyboard, can be used in the occasion that family security door etc. subjects to accident or deliberately destroys, safe and reliable.

3) input is convenient fast, and 6 password inputs consuming time generally are no more than 10 seconds.

4) key position can be according to the use occasion flexible configuration, and adaptability is strong.

5) be easy to learn and use, it is extensive to be suitable for the crowd.
