Abstract
The invention discloses a peeping-proof password input method. When a user requests a password verification, a system generates a random key comparison table, and meanwhile the random key comparison table is displayed on a displayer through a virtual digital keyboard; and virtual digital keys of the virtual digital keyboard are in one-to one correspondence with subscripts. The subscripts are displayed periodically in a manner of momentary flashing after the subscripts are spaced at intervals. The subscripts are taken as replacement digits to be input after the user observes flashing of the subscripts according to password digits clearly. After the system receives the input, the key comparison table is looked up so that the replacement digits are reduced into password digits to be recorded and stored, and then subscript units of the key comparison table are refreshed, so that a new group of digits are generated randomly. The finish confirmation is given after the user finishes inputting completely, the recorded and stored password digits are combined into passwords in sequence and submitted to a verification system for verification after the system receives a confirmation instruction. According to the peeping-proof password input method, random changing and flashing of the subscripts of the virtual digital keyboard are used, so that the subscripts are difficult to see clearly and memorize, the password cannot be deduced reversely, and the security of password input is guaranteed.
Description
Technical field
The present invention relates to field of information security technology, particularly a kind of anti-cipher-code input method of peeping.

For solving the problem of above-mentioned existence, the purpose of this invention is to provide a kind of anti-cipher-code input method of peeping, it utilizes following on the virtual digit keyboard to be marked on after each button input all can stochastic transformation and the of short duration mode of flashing periodically of the being replacement numeral of pointing out the user to import password figure.Because subscript is difficult to all be seen clearly and remember, so password can't be reversed derivation, make the safety of password input be guaranteed.
The present invention provides for achieving the above object a kind ofly anti-ly peeps cipher-code input method, may further comprise the steps:
Step 1: during user's requests verification password, system generates at random, and the button table of comparisons is shown to the user at display with the virtual digit keyboard simultaneously, it is corresponding one by one not repeat the subscript unit at random by 10 push-button units of 0 to 9 and 0 to 9 10 respectively in the described button table of comparisons, it is corresponding one by one that described virtual digit keyboard does not then repeat subscript by 10 virtual digit buttons of 0 to 9 and 0 to 9 10 respectively at random, described be marked with periodically at interval the some time down after of short duration mode of flashing show;
Step 2: the user finds the virtual digit button of same numbers according to its password figure at the virtual digit keyboard, and observes the wait subscript corresponding with this virtual digit button and flash;
Step 3: after treating that the user sees the subscript of flashing clearly, on numeric keypad with the digital keys input as an alternative of viewed subscript;
Step 4, search subscript unit identical with replacing numeral in the button table of comparisons after system's reception input immediately and its corresponding push-button unit is reduced and record storage as password figure, system generates one group of new numeral at random with the subscript unit of the button table of comparisons at once subsequently, and the subscript of synchronous refresh virtual digit keyboard, wait for that then the user imports;
Step 5, the user imports n again according to the method for step 2 and step 3 and replaces numeral, then n password figure stored in the reduction of four method and record set by step in system, and again the subscript unit of the button table of comparisons is generated one group of new numeral at random, and the subscript of synchronous refresh virtual digit keyboard, wait for that then the user imports;
Step 6, the whole inputs of user finish and confirm to finish input, after system's confirmation of receipt END instruction whole password figures of storing of record are combined into password in regular turn and submit to the check system checking.
The invention has the beneficial effects as follows that the password figure that utilizes on the one hand virtual digit keyboard prompting user will need to import is replaced allows the person of peeping peep the press button of digital keyboard operation also not know real password figure; On the other hand, be marked on after each button all one group of new numerals of random refresh in order to the virtual digit keyboard of pointing out the user following, and be periodically with the time compole short mode of flashing show, so just making the person of peeping not only can't see clearly but also be difficult to remember these subscripts also just can't be in order to the decryption of oppositely deriving in conjunction with the button operation of user on numeric keypad, thereby has protected the safety of password; Another aspect in addition, because the input of each button only needs to observe a subscript therefore neither can increase the memory burden and can guarantee that also thereby it sees this subscript clearly and do not influence its operation, and whole input operation custom is consistent with conventional password input habit so reduced operation easier again for the user; Again on the one hand, the present invention program can only realize need not to change system hardware by software for input block is based on system for computer, and because password input and reduction all can be finished in the input block of password, system for Client will need not the background server system is done any change and upgrading like this, and therefore the transformation difficulty to total system is little, cost is low and do not have system risk.

| Push-button unit | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| The subscript unit | 3 | 7 | 9 | 5 | 0 | 6 | 4 | 1 | 8 | 2 |
Table 2
The password figure of the 2nd needs input of user is ' 3 '.
The user observes on the virtual digit keyboard 1 numeral and is the flashing of ' 3 ' virtual digit button 11 corresponding subscripts 12, and be digital ' 5 ' according to the button table of comparisons (table 2) this subscript 12 this moment.
After seeing subscript 12 clearly, the user on numeric keypad 2 as shown in Figure 3, numeral ' 5 ' is imported as the replacement digital keys of password figure ' 3 '.
System is after receiving the button input, replace numeral ' 5 ' according to this of input and in the button table of comparisons (table 2), search numeral and be ' 5 ' subscript unit, with this corresponding push-button unit in subscript unit namely numeral ' 3 ' as password figure reduction and record storage.Finish the 2nd reduction of replacing numeral and password figure thus.System calls random function at once and again the subscript unit of the button table of comparisons is generated one group of new numeral at random subsequently, and the subscript 12 of synchronous refresh virtual digit keyboard 1, system wait user's input then again.
The user repeats above input operation until the replacement numeral input of finishing remaining password figure.
Confirm to finish input import the replacement numeral of whole password figures as the user after, system reduced and recorded the password figure of storage successively before foundation after the confirmation of receipt END instruction: 8,3... its combination is restored password: 836529, then password is submitted to the cryptographic check system verification of background server.
