Abstract

The invention discloses a method for inputting graphic random passwords, which relates to a password input method for a keyboard-less large-screen touch screen mobile device. The method is characterized in that a digital recognition unit for transmission is replaced by a graphic recognition unit which has no mutual logical relation with the digital recognition unit; and when a user enters into a password input unit, a view dialog box which is formed by n*m matrixes is popped up by a login program, the view dialog box is used for inputting passwords, a specific value defined by a graph is generated in a system memory after the graph is clicked by the user, the passwords can be formed after the graph is clicked by the user for a couple of times, the selection function can be stopped by a system if one click during a clicking process is long press, a dialog box can be hidden, the passwords can be transmitted to a background verification unit, the system can be logged in if the passwords are right, and the user can be noticed to input the passwords again if the passwords are wrong. When the user enters into a password selection dialog box for the next time, the matrixes in the password dialog box are rearranged, the positions clicked by the user when the user logs in the system in each time are random, graphs without mutual logical relations are additionally used for distinguishing, thus the passwords input in each time seem different by others, and the safety of the passwords is increased.

Description

Graphical random cipher input method

Technical field

The present invention is a kind of random cipher input method of graphical identification, is mainly used in giant-screen touch-control mobile device, such as mobile phone, and the mobile devices such as ipad.

Background technology

Mobile device is in continuous direction develop rapidly towards function complexity easy and simple to handle, the login method of some excellent programs, particularly need to use the program of keyboard can not on current popular giant-screen touch-control mobile phone, adapt to, the substitute is the appearance of soft keyboard, but soft keyboard often is difficult to operation, even sometimes make us very much very irritated, make the user would rather abandon the complexity of password and simple password is set, safety has been buried great hidden danger, gesture slip cipher-code input method has appearred afterwards, but often because the touch screen induction is insensitive, the user need to repeat could input several times correctly.Mobile device is by the various issued transaction of wide variety of user, and the safety of user profile also more and more comes into one's own, a kind of safe and convenient cipher-code input method of current urgent need.

Find by literature search, Chinese patent application number is 200410052612.1, publication number is CN1588280, patent name: dynamic cipher input method and keyboard thereof, it proposes a kind of dynamic cipher input method, numeral of the each click of user, the numeral on the keyboard again random alignment waits for that the user reselects.The method is to divide option with the digital block, do not to obscuring of password, the person of peeping can very fast discovery user selection which, and each click is carried out once randomly ordered, can allow each click of user go again to seek the position of next time clicking target afterwards, affect the continuity of user's thinking and action, increase complexity and the time of input, therefore the method also is not very perfect, is difficult to be used widely.

Summary of the invention

This method is in order to overcome all difficulties in the current password input, particularly on convenient and swift aspect and the secure context, a kind of use patterned sections subdivision is proposed as the password option, make its vivid and interesting, and be difficult to distinguish for the people of unknown password, certainly the user for known password can find fast the password option of oneself and then input fast password, allows the person of peeping have little time reaction and has just entered system.Even the person of peeping has remembered order and position that the user clicks, after program entered next time, the order of matrix rearranged, and the click order of last time is not correct, has played good safety effect.The present invention is mainly by following process implementation, at first the user enters the graphical passwords inputting interface and selects figure, each figure is given a particular value by program, after clicking, several times form a value string, long by confirming password after a certain graphical options, hide cryptographic interface, password imports the backstage into to be verified, if correctly enter system, if miscue user cipher mistake please reselect, the user confirms to reselect then again to enter the codon usage interface, the interface matrix is random alignment again, if the user successfully enters system, next time login enters the codon usage interface again, and the interface matrix is random alignment again also.

The present invention has substantive distinguishing features and marked improvement, adopt figure or symbol to come the recognition code option, can play and well obscure effect, significantly reduced the interaction times of user and equipment, make more convenient operation, the adding of random cipher function has improved the security of password more.

Description of drawings

Fig. 1 is the simple interface synoptic diagram of this method, among the figure each parts be respectively 1, screen 2, user name 3, user list 4, Password Input

Fig. 2 is the codon usage cell schematics of this method, among the figure each parts be respectively 1, screen 2, codon usage view 3, graphical options

Fig. 3 is that this method enters the codon usage cell schematics described next time, and each parts is respectively 1 among the figure, screen 2, codon usage view 3, next time enter the out of order arrangement option behind the codon usage unit

Embodiment

The user at first according to when registration the figure array that provides of system select the permutations of code that will generate, the system backstage generates corresponding character or the numerical ciphers of figure according to user-selected figure, certainly this password is sightless to the user, convenient judgement when only carrying out password authentification for system.

Such as Fig. 1, logging program user basic interface is made of following part: the user name input frame, the user name list button, enter the password OptionButton, the user enters login interface, the Password Input button just can show after the input account number, and screen will eject the codon usage view after the user clicks the Password Input button.

Such as Fig. 2, this view is that the matrix by a n*m consists of, and element is n*m figure or the Symbol Option in the matrix.The user selects figure, when certain click event of user is pressed event for length, system's generating cipher is also hidden the codon usage view, password is sent to authentication unit, if the checking return results be correct, if the acquisition authority that enters system then is authentication failed, prompting user password mistake please reselect input.

Such as Fig. 3, when the user reenters codon usage view (comprise last time password mistake and new once login) at every turn, matrix random alignment again all in the view, to make the user input the track of password not identical at every turn, can play and well prevent the password leakage effect, it is out of order not need each click to carry out, and uses thereby avoid affecting the user.

Claims

1. cipher-code input method that is used for giant-screen touch-control mobile device, the method is based on graphical identification and random sequence input password, it is characterized in that, when the user enters the codon usage unit, screen ejects the figure selecting view, the rectangular arranged of some graphical options journey n*m on this view, the user clicks selection wherein after certain figure, the value that program backstage this figure of automatic acquisition shines upon, deposit this value in internal memory, and wait for that the user selects next time, click in the process of several times the user, if certain is clicked as clicking more for a long time, the value that program will be clicked formation at every turn is combined into character string, form password, and hide dialog box simultaneously, system is sent to authentication unit with password and verifies.
