Description

Icon-based password authentication method and device with random character segment mark

[0001] The present invention relates to an interaction technology between a user and a computer, and relates to a password authentication method and apparatus, and more particularly to an iconic password authentication method with a random character segment mark and a device applying the same. Background technique

[0002] With the advent of the information age, people often set passwords for various types of computer equipment, mobile phones, and various accounts that hold personal information in order to protect their identity and property. Moreover, since the password is sneaked into by the criminals, it often causes irreparable damage to the user. Therefore, how to effectively prevent the user from being sneaked by the criminals when entering the password has become a social problem that needs to be solved urgently.

[0003] At present, when a user inputs a password in various types of computer devices, in order to prevent the input content from being seen by others, the system generally adopts a non-meaningful special character instead of the input password in the password input box on the screen. At the same time, in order to increase the confidentiality intensity, users often set the password to a meaningless long string that is not easy to be accurately and quickly blinded. However, in this way, if only the special character of the substitute password is displayed in the password input box on the screen, the user It will be difficult to find errors in the input in time. Moreover, what is hidden is only the password on the screen, but it cannot cover the action when the user inputs the password with the finger on the keyboard at the same time, and the password is still obtained by the other person by observing and analyzing the finger action when the user operates the button.

[0004] In this regard, a common measure in the banking environment is to set a mask on the keyboard that blocks the finger operation.

However, there is a contradiction between the occlusion effect of the mask and the difficulty of the user's operation. The larger the occlusion angle, the better the hidden effect, but the higher the difficulty of operation, affecting the user experience.

[0005] At the same time, in home and office environments, it is obviously not convenient to set a mask on the keyboard of a general desktop computer or a notebook computer, but there are still frequent password input operations in such an environment. On the screen of the mobile phone, it is also more difficult to hide the action of the finger, making it easier to reveal the password or the lock screen pattern.

[0006] Moreover, in modern society where concealed camera equipment is readily available, it is hard to prevent sneak peeks at the use of high-tech means to peek passwords. General measures have been difficult to parry. In order to improve the difficulty of cracking, setting various types of passwords is generally required to use long characters, and may also include a combination of uppercase and lowercase characters. But how to remember such complex and abstract passwords has always been a headache for people. [0007] In summary, in the current various password input environments, not only the password is easily leaked. Moreover, it is difficult for the password owner to determine whether his or her password has been stolen by criminals during the input operation, and can only be remedied and prevented by frequently changing the password. However, passwords that meet the difficulty of cracking are not easy to remember. The result of frequent replacement will increase people's memory burden and make people more distressed.

[0083] The term "marking explicit control unit" as used herein refers to a process control event in which a screen display and a non-display state of a random character segment mark are operated by a user's operation action, for example, may be a virtual or physical button, Any set area of the screen can be physically triggered or triggered by the mouse cursor.

[0084] The opening and closing of the "marked display control unit" referred to in the present application may be used as a mark display control list. The same button of 兀 is completed by two pressing actions, or the same button is pressed and released to complete.

[0085] The present application provides an iconic password authentication apparatus with a random character segment mark, including a display unit, a data processing unit, and an input unit.

[0086] When the user enters the password setting step, the display unit displays at least one set of icon groups including a plurality of icons; in each group of icon groups, the user selects at least one icon as a password icon; each password icon At least two icons are included;

[0087] When the user enters the password authentication step, the data processing unit is configured to allocate each of the different random segment markers for each icon in each group of the icon group, and send the random segment flag of each icon to the display. Unit, each random character segment contains at least one character;

[0088] The display unit includes a mark display implicit control unit, and the display unit is further configured to display the icon group including the password icon, and after the mark display implicit control unit is turned on, in a position corresponding to each icon Display a random character segment of each icon;

[0089] the input unit is configured to enable the mark display implicit control unit, and acquire the currently received character segment of the user input, and send the input character segment to the data processing unit;

[0090] The data processing unit is further configured to compare each input character segment received successively with a random character segment mark of each password icon successively displayed by the display unit, and determine and finally prompt the current password authentication according to the comparison result. Whether it passed;

Further preferred technical features of the above device include:

[0092] the display unit further includes a virtual keyboard;

[0093] After the user enters the password authentication step, the input unit is further configured to close the mark display implicit control unit, and the display unit hides that the random character segment mark is being displayed, and displays the virtual keyboard;

[0094] the input character segment is from an operation event of the user on the virtual keyboard;

[0095] When the last input segment is not completely input, the display unit automatically hides the virtual keyboard and redisplays the icon.

[0096] Further preferred technical features of the above apparatus include:

[0097] the display unit further includes a virtual keyboard;

[0098] After the user enters the password authentication step, the display unit is configured to simultaneously display the random character segment mark and the virtual keyboard. , and the random segment mark overlaps over the upper layer of the virtual keyboard;

[0099] when the virtual keyboard is triggered, the display unit automatically hides the random character segment mark;

[0100] the input character segment is from an operation event of the user on the virtual keyboard;

[0101] When the input segment of the last segment is not completely input, the display unit automatically hides the virtual keyboard and redisplays the icon.

[0102] Further preferred technical features of the above apparatus include:

[0103] the display unit is a touch display screen;

[0104] The user operates the virtual keyboard by a touch action to obtain an input character segment.

[0105] If the display unit adopts a touch display screen, the input character segment information may be a virtual keyboard from which the user operates by a touch action.

[0106] As described above, after the user enters the password authentication step, when each random character segment mark is being displayed, each icon may be hidden, so that the random character segment mark and the icon are alternately displayed.

[0107] In this way, when the present invention is applied in the above manner in a product such as a password lock, a POS machine, a smart phone, etc., the icon, the random character segment mark, and the virtual keyboard can be alternately displayed in the same display area of the touch screen, the maximum The limit compresses the area required for the password authentication interface.

[0108] After the mark display implicit control unit is set in the present application, since the random character segment mark is displayed by the display unit only after the mark display implicit control unit is turned on, when the user performs password authentication, the user may first find it. The set password icon, and then manipulate the mark display control unit to call out the random character segment mark, shortening the display time of the random character segment mark, and reducing the risk that the voyeur happens to observe the position of the password icon.

[0109] After entering the password authentication step, when the display unit is displaying the random character segment mark, if the mark display control unit is turned off, the random character segment mark being displayed will be hidden, and the display unit will display the virtual keyboard; After the last input segment is completely entered, the virtual keyboard is automatically hidden and the icon is redisplayed.

[0110] In this way, the user can autonomously control the display and hiding time of the random character segment mark by the manipulation action of the mark display implicit control unit. That is to say, when the user finds a password icon set by himself, first displays the random character segment mark by the manipulation action of the mark display implicit control unit, and then quickly remembers the random character segment of the key password icon. Immediately after the mark, the mark is hidden again. The meta-manipulation action hides the random segment markers. While the random segment marker is hidden, the virtual keyboard is also immediately displayed on the screen, simplifying the manipulation steps.

[0111] Through the above method, the random character segment mark and the virtual keyboard can be arranged alternately in the same display area, which provides conditions for compressing the physical area of the password authentication interface.

[0112] Further, after entering the password authentication step, the random character segment mark and the virtual keyboard are simultaneously displayed, and the random character segment mark overlaps the upper layer of the virtual keyboard; when the virtual keyboard is triggered, the random character segment mark is automatically hidden; After the last input segment is completely input, the virtual keyboard is automatically hidden, and the display unit redisplays the icon.

[0113] Such a purpose is to make the virtual keyboard overlapped in the background of the random character segment mark, and when any button of the virtual keyboard is triggered, the random segment mark is immediately hidden, and only the virtual keyboard is separately displayed, thereby omitting The operation of the virtual keyboard is called up. In addition, since the virtual keyboard is automatically hidden after the last input segment is completely input, and the display unit redisplays the icon, the operation of alternately displaying the virtual keyboard and the icon group is further omitted, and the user is reduced again. Steps.

[0114] Further, after entering the password authentication step, each icon is hidden when each random segment mark is being displayed.

[0115] The advantages displayed when the random segment mark is different from the icon are: The alternately displayed icon and the virtual keyboard are in the same display area, so that the icon and the keyboard button can be maximized without mutual interference. The size display can further increase the difficulty of the observer to observe and record the content of the icon corresponding to the random segment mark, thereby improving the anti-spy performance.

[0116]

[0117] Embodiment 1, as shown in FIGS. 1 to 9, this is an iconic password authentication device with a random character segment mark, including a touch display screen as a display unit and a button as a mark display control unit 3.

[0118] Referring to FIG. 1, when password authentication is performed, the touch display first displays the first group of icons including 16 icons 1. The user then performs the following series of finger actions:

[0119] The first finger action:

[0120] After the user finds the first password icon preset in the first group of icon groups, press the mark display control button 3 to hide the 16 icons on the touch display screen, and replace with 16 sets of random segment marks 2 (see Figure 2). [0121] The second finger action:

[0122] After quickly observing and remembering a set of random character segment marks consisting of 3-digit numbers located at the position of the first password icon that has disappeared, the button is released. At this time, the random segment mark is replaced by the virtual keyboard 4 (see Fig. 3).

[0123] 3rd, 4th, and 5th finger movements:

[0124] On the virtual keyboard 4, three numbers of random character segment marks constituting the first password icon are sequentially pressed. At this point, the virtual keyboard 4 on the display is replaced by the second set of icon groups (see Figure 4).

[0125] The sixth finger action:

[0126] After finding the second password icon preset in the second group of icon groups, press the mark display control button 3 to hide the 16 icons on the touch display screen, and replace it with 16 Group random character segment marker 2 (see Figure 5).

[0127] The ^seventh finger action:

[0128] After quickly observing and remembering a set of random character segment marks consisting of 3-digit numbers located at the position of the second password icon that has disappeared, the button is released. At this time, the random segment mark is replaced by the virtual keyboard 4 (see Fig. 6).

[0129] The 8, 9, and 10 finger movements:

[0130] On the virtual keyboard 4, three numbers of random character segment marks constituting the first password icon are sequentially pressed. At this point, the virtual keyboard 4 on the display is replaced by the third set of icon groups (see Figure 7).

[0131] The 11th finger movement:

[0132] After finding the third password icon preset in the third group of icon groups, press the mark display control button 3 to hide the 16 icons on the touch display screen, and replace it with 16 Group random segment marker 2 (see Figure 8).

[0133] The 12th finger movement:

[0134] After quickly observing and remembering a set of random character segment marks consisting of 3-digit numbers located at the position of the third password icon that has disappeared, the button is released. At this time, the random segment mark is replaced by the virtual keyboard 4 (see Fig. 9).

[0135] The 12th, 13th, and 15th finger movements:

[0136] On the virtual keyboard 4, three numbers of random character segment marks constituting the first password icon are sequentially pressed. [0137] After that, the system determines whether the current round of password authentication passes according to whether the three sets of random character segments typed by the user match the three password icons preset in advance, and finally displays the password on the screen. Feedback "correct" or "wrong password".

[0138] In the above finger movement, the first and second operations, the sixth and seventh operations, and the eleventh and twelfth operations belong to the same button pressing and releasing operation, and can be regarded as one motion. Therefore, the entire password authentication process actually requires 12 finger actions. The length of the interval between button press and release is the random segment marker formed by the user according to whether it has been clearly seen and temporarily remembered the three digits corresponding to the password icon, and is controlled by itself.

[0139] In this embodiment, by controlling the mark display control button 3, the icon 1, the random character segment mark 2, and the virtual keyboard 4 can be alternately displayed in the same display area on a touch display screen. Therefore, when applied to smart password door locks, handheld POS machines, and smart phones, a relatively compact product configuration can be obtained, and the password authentication interface requires a minimum of construction area.

[0140] Embodiment 2 of the present invention is shown in FIGS. 10 to 18.

[0141] Unlike the first embodiment, the icon-type password authentication apparatus with random character segment marks in the second embodiment also uses the touch display screen itself as a mark display implicit control unit.

[0142] Referring to FIG. 10, when password authentication is performed, the touch display screen first displays a first group of icon groups including 16 icons 1. The user then performs the following series of finger actions:

[0143] The first finger movement:

[0144] After the user finds the first password icon preset in the first group of icon groups, the user touches any part of the touch display screen with the function of marking the hidden control unit with the finger, so that 16 maps are displayed. The character is hidden, replaced by a set of 6 random character segment markers 2 (see Figure 11) and a virtual keyboard 4 with a blurred background image state superimposed with the random segment segment markers.

[0145] The second finger action:

[0146] After quickly observing and remembering a set of random character segment marks consisting of 3-digit numbers at the position of the first password icon that has disappeared, the first number is pressed on the virtual keyboard 4. At this point, the random character segment mark 2 disappears and only the virtual keyboard 4 is displayed on the screen (see Figure 12).

[0147] The third and fourth finger actions:

[0148] The last two digits of the random character segment mark constituting the first password icon are sequentially pressed on the virtual keyboard 4. At this point, the virtual keyboard 4 on the display is replaced by the second set of icon groups (see Figure 13). [0149] The fifth finger action:

[0150] After finding the second password icon preset in the second group of icon groups, touching any part of the touch display screen with the function of marking the hidden control unit with the finger again, so that 16 maps are made. The character is hidden, replaced by a set of 16 random character segment markers 2 (see Figure 14) and a virtual keyboard 4 with a blurred background image state superimposed with the random segment marker (see reference numeral 4 in Figure 14).

[0151] The sixth finger action:

[0152] After quickly observing and remembering a set of three-digit random segment marks located at the position of the second password icon that has disappeared, the first number is pressed on the virtual keyboard 4. At this point, the random character segment mark 2 disappears and only the virtual keyboard 4 is displayed on the screen (see Figure 15).

[0153] The seventh and eighth finger actions:

[0154] On the virtual keyboard 4, the last two digits of the random character segment mark constituting the second password icon are sequentially pressed. At this point, the virtual keyboard 4 on the display is replaced by the third set of icon groups (see Figure 16).

[0155] The 9th finger movement:

[0156] After finding the third password icon preset in the third group of icon groups, touching any part of the touch display screen with the function of the mark display control unit again with the finger, so that 16 pictures are made. The character is hidden, replaced by a set of 16 random character segment marks 2 (see Fig. 17) and a virtual keyboard 4 state of the blurred background picture state superimposed with the random character segment marks (see reference numeral 4 in Fig. 17).

[0157] The 10th finger movement:

[0158] After quickly observing and remembering a set of three-digit random segment marks located at the position of the third password icon that has disappeared, the first number is pressed on the virtual keyboard 4. At this point, the random character segment mark 2 disappears and only the virtual keyboard 4 is displayed on the screen (see Figure 18).

[0159] The 11th, 12th finger action: On the virtual keyboard 4, the last two digits of the random character segment mark constituting the third password icon are sequentially pressed.

[0160] After that, the system determines whether the current round of password authentication is passed according to whether the three sets of random character segments typed by the user match the three password icons preset in advance, and finally displays the password on the screen. Feedback "correct" or "wrong password".

[0161] Compared with Embodiment 1, Embodiment 2 further simplifies the operation steps of the user by superimposing the manner of displaying the random character segment mark and the virtual keyboard, and is superimposed and displayed in the background image of the random character segment mark. The virtual keyboard also acts as a technical effect that interferes with the voyeurism of others.

[0162] Embodiment 3 of the present invention is shown in FIGS. 19 to 22.

[0163] Referring to FIG. 19, this is a password authentication device with a display screen and a physical keyboard 5. After entering the password authentication program, the display screen first displays 16 icons 1. After the user presses the Ctrl key in the physical keyboard 5 as the mark display control unit, the icon 1 on the display screen is replaced by the random character segment mark 2 (see Figure 20).

[0164] Thereafter, when the user presses a numeric button on the physical keyboard 5, the random segment mark on the display screen is hidden. When the third number button is pressed, the display will show the second set of icon groups.

[0165] By analogy, when all the icon groups are sequentially displayed, and the random character segment marks that the user thinks belong to the password icon are sequentially input on the physical keyboard, the system feeds back the prompt of whether the password authentication is passed.

[0166] In this embodiment, the interval between when the Ctrl button is pressed and when the first numeric button is pressed is followed, and the user is based on whether or not the random character segment mark of the specific position is viewed and recorded. , control by yourself. Obviously, the shorter this interval, the more difficult it is for the onlookers to peek at the password information.

[0167] When the user enters the setting step, the random character segment mark 2 list style shown in FIG. 20 may be changed to the style of the upper and lower two random character segment marks 2 in each cell shown in FIG. 21, or Each of the cells shown in Fig. 22 has a pattern of upper, middle, and lower random character segment marks 2. Moreover, it is also possible to select whether a plurality of random character segment marks 2 in each cell belong to the corresponding same icon in the setting.

[0168] If the selection belongs to the same complete icon, then typing any random segment of the password in the cell of the password icon is considered to be correct. In this case, multiple random segment markers within each cell will increase the peek of the bystander.

[0169] If the selection does not belong to the same complete icon, but belongs to the upper part and the lower part of the same icon, respectively, or belongs to the upper part, the middle part, and the lower part of the same icon respectively, then the password is set. When the icon is used, it is necessary to specifically determine whether it is the upper part or the lower part of the icon, or the upper part, the middle part or the lower part. In this case, the up and down position or the upper, middle, and lower positions of the random segment mark in the same cell must also match the up and down position or the upper, middle, and lower positions of the preset password icon. In this case, multiple random segment markers in each cell not only increase the peek of the bystander, but also greatly increase the password encryption level.

[0170] When the device itself includes a user initial authentication program of the fingerprint scanning mode, or includes a user name input process, the above-mentioned settings selected by the specific user will enter the password authentication step. At the time, the system is first subjected to the subsequent authentication process according to the pre-set authentication method according to the specific identity initially confirmed. In other words, different users can choose different authentication level and anti-peep difficulty.

[0171] It is apparent that in the above embodiment, if a touch display having an ultra-narrow viewing angle feature is employed, an absolute anti-peeping effect can be theoretically obtained.
