Description
Technical Field
The invention relates to an anti-peeping touch feedback password input system and method, and belongs to the technical field of safe interaction of touch screen devices.
Background
The use of passwords to unlock the screen-locked state of a touch screen device and to access key information stored in a smart device, such as bank accounts, online payments, etc., has become the key to the security interaction technology of touch screen devices today.
The existing touch screen password input method mainly comprises the following steps: a numeric PIN code, a pattern lock, and a character code.
The digital PIN code (full name: Personal Identification Number) is a group of passwords composed of 4 or 6 digits 0-9, and is widely applied to the fields of unlocking, payment and the like. The device presents a numeric button interface and the user clicks the buttons to enter the password in sequence. Its advantages are easy memory and high input efficiency; but the disadvantage is that the password is easy to be peeped and stolen, once the password input process is observed by others, others can easily remember the password to cause password leakage.
The pattern lock is an area consisting of a dot matrix of 3 × 3, and a user slides and draws a certain pattern between points on the dot matrix as a password.
A character password refers to a set of character sequences consisting of letters, numbers, and symbols. The device presents a button interface of the computer keyboard, and the user clicks the buttons to input the passwords in sequence. The method has the advantages that the information dimension of the password is high, and the cracking difficulty is high; however, the disadvantage is that displaying a full keyboard on a small touch screen device results in a small single button area, a high input error rate and a slow input speed. Moreover, the user often sets some simple passwords, such as abc123, birthday, pinyin of name, and the like, so that the passwords are easy to guess by experienced hackers and break.
Although face recognition and fingerprint recognition technologies have been applied to touch screen devices in recent years, these technologies have corresponding disadvantages. For example, face recognition needs to be used under the condition of sufficient light, and the recognition rate cannot reach 100%; fingerprint recognition has a low recognition rate in the case of a finger that is sweaty and wet, and not all touch screen devices are equipped with fingerprint recognition means. And, when these identification techniques fail, passwords remain the most effective method of secure interaction as a back-up scheme.
Disclosure of Invention
In order to solve the problems in the background art, the invention provides an anti-peeping touch feedback password input system and method.
The method of the present invention to solve this problem is to combine the application of gesture sliding on the touch screen and vibrotactile feedback of the device to enter the password. In the whole input process, no graphic image information is needed on the screen of the equipment, an operator can feel weak vibration feedback of the equipment only when a finger slides to certain preset areas, and the operator determines the digital password to be input according to the frequency of sliding the finger through the vibration touch area. The method can realize blind operation of password input and effectively prevent peeping.
The specific technical scheme is as follows:
a peep-proof tactile feedback password input system comprises:
the touch screen is provided with a plurality of parallel invisible cross bar touch areas, detects whether the touch position of a finger is in one cross bar touch area, and sends the touch position information of the finger to control equipment;
the control module generates a vibration control signal and a counting signal according to finger touch position information received from a touch screen, sends the vibration control signal to vibration equipment to control the vibration equipment to generate vibration, and sends the counting signal to a counter for counting;
the device comprises a vibration module, a vibration device and a control module, wherein the vibration device is connected to a touch screen or directly connected to a finger and is fed back to the finger through vibration;
the counter is used for receiving the counting signal sent by the control equipment to carry out accumulated counting.
And the control module generates a vibration control signal according to the finger touch position information to know that the finger is in a horizontal bar touch area, and sends the vibration control signal to the vibration equipment to enable the vibration equipment to perform vibration feedback on the finger.
The control module learns according to the information of the finger touch position, the finger touch position sequentially passes through the process of sliding through a horizontal bar touch area from the outside of the horizontal bar touch area, the inside of the horizontal bar touch area and the outside of the horizontal bar touch area, a counting signal is generated, and the counting signal is sent to the counter to increase the count by one.
The touch screen, the counter, the control module and the vibration module are integrated in an integrated device, and specifically can be a device with a touch screen, such as a smart phone and a tablet computer.
Secondly, an anti-peeping tactile feedback password input method comprises the following steps:
the touch screen is provided with a plurality of horizontal bar touch areas which are parallel and can provide vibration feedback, the horizontal bar touch areas are invisible, the horizontal bar touch areas are arranged at equal intervals, the height of the horizontal bar touch areas is equal to the arrangement interval, a finger slides on the touch screen, and the finger senses the vibration feedback to input a digital password in the sliding process of the finger on the touch screen.
A finger slides on the touch screen, vibration feedback is provided for the finger when the finger is located in the cross bar touch area, and vibration feedback is not provided for the finger when the finger is located outside the cross bar touch area.
With the finger sliding up and down the screen, the user can feel the continuous vibrotactile feedback provided by the device each time the finger slides into any one of the cross bar regions. The vibration feedback of the device stops immediately when the finger slides out of the bar area.
The method comprises the steps that a finger slides on a touch screen, the finger slides in and out of a plurality of horizontal bar touch areas up and down randomly to input a digital password, in the process that the finger keeps in contact with the touch screen, a digital value P is set to be 0 initially when the finger starts to contact the touch screen, the digital value P is added with 1 when the finger slides through one horizontal bar touch area every time, when the finger leaves the touch screen, the input of one digital password is finished, and the last digital value is used as the input number.
The order and number of times the finger slides in and out arbitrarily up and down between the plurality of bar haptic areas is arbitrary. Thus, the manner in which any one of the same numbers is input is varied.
The fact that the finger slides through the bar touch area each time means that the touch position of the finger detected by the touch screen sequentially goes through the processes of the outside of the bar touch area, the inside of the bar touch area and the outside of the bar touch area.
The providing of the vibration feedback is to provide the vibration in an intermittent manner. Specifically, short vibration time and vibration interval time are set, and the vibration time and the vibration interval time are alternated. The vibration modes formed are: the vibration time w1, the vibration interval time w2, the vibration time w1, the vibration interval time w2, … … are repeated continuously to provide intermittent vibration, and the vibration time w1 and the vibration interval time w2 are repeated continuously.
The invention has the beneficial effects that:
1) according to the invention, blind operation is realized by using the touch screen sliding gesture and vibration touch feedback, and peeping is prevented. Even if the password input process is exposed to other people, other people can hardly guess the input password, and the safety is high.
2) In the input process, the password input can be completed only by sliding the fingers up and down, and the operation is simple and quick.
3) The technology of the invention can be conveniently realized on various touch screen devices provided with vibration sensors: such as smart phones, tablet computers, etc.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.
The specific implementation of the invention comprises:
1) three bar touch areas 101 are divided in the center of the touch screen, the height 102 of each area is equal to H, and the interval 103 of each bar touch area is also H.
Fig. 1 is a schematic diagram of key parameter settings of a vibration touch sensing area presented by a mobile phone touch screen as an example in the present invention. Where 101 represents the location of three bar touch areas, 102 represents the height of each bar touch area as H, and 103 represents the spacing between each bar touch area as H.
The value range of H obtained by user test can be any value between 5 mm and 7 mm.
The positions of the three horizontal bar touch areas are the central area of the screen of the equipment, but in order to ensure that a finger does not touch any touch area when just clicking the screen in the interaction process, the positions of the three horizontal bar touch areas can be finely adjusted up and down according to the coordinates of the finger clicking the screen.
2) The device provides intermittent vibration feedback when a finger touches the three bar touch areas, and the device does not have vibration feedback when touching other areas of the screen. The tactile feedback mode of the vibration feedback is as follows: the vibration time w1, the vibration interval time w2, the vibration time w1 and the vibration interval time w2, … … are repeated continuously, and the vibration interval time of w1 and w2 are repeated continuously.
The value range of w1 obtained by user tests can be any value between 10 ms and 30ms, and the value range of w2 can be any value between 50ms and 150 ms. The vibration pattern is only perceptible by the hand-held device and cannot be fed back by visual or audible inspection of the device.
The specific implementation method for inputting a digital password comprises the following steps:
1) the finger clicks any position on the screen, and at the moment, the positions of the three horizontal bar touch areas representing vibration feedback can be dynamically adjusted to ensure that the position where the finger starts clicking is not overlapped with the three horizontal bar touch areas;
2) the user can feel the sustained vibrotactile feedback provided by the device each time the finger slides up and down the screen into any one of the bar tactile areas. Stopping immediately when the finger slides out of the vibration feedback of the device of the touch sensitive area of the cross bar;
3) each time the vibration area slides across the bar, the digital value P to be input is added with 1 (the initial value is 0); the finger leaving the screen represents the ending of the number to be entered and the current P value is a numeric code to be entered. For example: if the number to be input is 6, any position of the screen can be clicked as the start, and the value P is 0; then sliding a finger upwards or downwards, and adding 1 to the P value after sliding to a certain horizontal bar touch area; then continuously sliding the finger to leave the current horizontal bar touch area, and moving to another horizontal bar touch area to add 1 to the P value; the operation of the above steps is repeated until the finger leaves the screen after the P value reaches 6, which is the number 6 to be input.
The method for inputting a plurality of digital passwords, such as 2, 3 and 4-digit digital passwords, comprises the steps of repeating the steps.
No graphic image information is provided on a screen of the equipment in the operation process, only the finger slides to the vibrating horizontal bar touch area, the equipment provides vibration feedback, and other people cannot observe the specific position of the horizontal bar touch area.
In order to increase safety, in the process of inputting a certain number, the user can repeatedly slide into and out of and pass through one horizontal bar touch sensing area from the upper position to the lower position, and can also switch 2 or 3 horizontal bar touch sensing areas. This makes the method of inputting any one identical number various and complicated, and even if the input process is completely exposed to others, it is difficult for others to guess the input number password only based on irregular sliding of the finger.
Therefore, no graphic image information is needed on the screen of the whole input process equipment, an operator can feel weak vibration feedback of the equipment only when a finger slides to certain preset areas, and the number of times that the finger slides through the vibration touch area is used for determining the digital password to be input, so that the purpose of determining the input digital password through the finger sliding on the touch screen and the vibration feedback sensed in the sliding process is realized.
Fig. 2(a), (b), and (c) show three input methods that can be used when inputting the number 6.
In fig. 2(a), the input method used for inputting the number 6 is: clicking the upper area of the screen, then sliding the three horizontal bar touch areas from top to bottom in sequence, and triggering the vibration touch to the user every time the mobile phone slides into any area, wherein the input number P is added with 1 (the initial value is 0). When the P value is 3 after sliding over the three bar touch areas, the user knows that at most three bar touch areas exist on the screen, and then slides down without the bar touch areas. The user can slide through the three bar touch areas from bottom to top in sequence, and the mobile phone triggers the vibration touch to the user every time the mobile phone slides into any area, which represents that the value of the input number P is increased by 1. When the value of P is added to 6, the user's finger leaves the screen to indicate that the input numeric code is 6.
In fig. 2(b), the input method used for inputting the number 6 is: clicking the upper area of the screen, then sliding two horizontal bar touch areas from top to bottom in sequence, and triggering a vibration touch to a user every time the mobile phone slides into any area, wherein the input number P is added with 1 (the initial value is 0). The P value is 2 when sliding over two bar touch areas. At this time, the user changes the finger sliding direction to sequentially slide through the two bar touch areas from bottom to top, and similarly, the P value is increased by 1 every time when the user slides through one bar touch area, and the P value is 4 after the operation is completed. The user then again slides the two bar touch areas from top to bottom in sequence to add the value of P to 6 and then leaves the finger off the screen representing the number 6 entered.
In fig. 2(c), the input method used for inputting the number 6 is: clicking a certain area in the center of the screen, and then sliding a horizontal bar touch area from top to bottom, wherein each sliding in the horizontal bar touch area represents that the value of the input number P is added with 1 (the initial value is 0). The user repeatedly slides up and down the horizontal bar touch area to add the value P to 5, then slides down the lowest horizontal bar touch area to add the value P to 6, and then leaves the finger from the screen to complete the input of the numeric code 6.
As can be appreciated from the three examples of input methods for the number 6 presented in fig. 2, there are also a number of methods of inputting the number 6. For example, an input method of first sliding through three areas from top to bottom, then repeatedly sliding in and out of a certain area, and the like. Thus, using the method of the present invention, the methods available for inputting the same number are various. This makes it difficult for others to guess the entered numeric code based only on irregular finger sliding, even if the process of entering is completely exposed to others. The problem of peep-proof digital password (PIN code) input and the safety of password input are solved.
Three tactile cross bar touch areas are drawn in fig. 1 and 2 for convenience of illustration, and no graphic image information is presented on the screen in actual use. And the device provides vibration feedback when the finger touches the three bar touch areas. The tactile feedback mode of the vibration feedback is as follows: the vibration time w1, the vibration interval time w2, the vibration time w1 and the vibration interval time w2, … … are repeated continuously, and the vibration interval time of w1 and w2 are repeated continuously. The value range of w1 obtained by user tests can be any value between 10 ms and 30ms, and the value range of w2 can be any value between 50ms and 150 ms. The vibration pattern is only perceptible by the hand-held device and cannot be fed back by visual or audible inspection of the device.
Because the user judges the input number according to the tactile feedback in the sliding process in the input process, the user does not need to look at the screen in the input process, namely the user can put the mobile phone in a hidden place to perform blind operation to complete the input of the password, and the password input safety is further improved.
