detailed description

In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

Fig. 1 is the method flowchart of the present invention and device thereof, as shown in Fig. 1, the method comprises:

In step S101: receiving the first position information and the second position information determined by the user in the cycle graph;

Specifically, the cyclic graphics include at least one of the following: circle, ellipse, and rectangle. For example, a dial can be used and the scale values (coordinate values, angle values, etc.) can be evenly marked. Both the above-mentioned first position information and second position information can be coordinates, angles, voltages, etc., and the user can set them according to specific situations and correspond the values of these information with the scale values on the cycle graph.

In step S102: obtaining the movement track from the first position to the second position;

Specifically, the movement trajectory from the first position to the second position of the pointer on the circular graph may be obtained according to the received user's gesture movement trace; A moving track from one location to a second location. The user can slide on the screen to move the starting point to the ending point. The pointer can be adjusted to point to a certain position by moving the pointer to achieve precise positioning, or the value of each touch point of the user can be directly enlarged and displayed, and the first position and the second position can be determined when a confirmation instruction is received.

In step S103: according to the movement track, calculate the physical feature information from the first position to the second position; the physical feature information from the first position to the second position includes at least one of the following: the first position to the second position The perimeter, voltage, area, angle, and number of cycles of the second position. For example: when the physical feature information is the number of cycles, then calculate the number of cycles from the first position to the second position; when the physical feature information is the circumference, the number of cycles is multiplied by the circumference of each cycle; when the physical When the characteristic information is the area, the number of circles of the cycle is multiplied by the area of each cycle figure; the specific physical characteristic information can be calculated by using the existing calculation method, and will not be listed here.

In step S104: comparing the physical feature information from the first location to the second location with preset physical feature information to obtain a first comparison result.

In step S105: comparing the first position information and/or the second position information with the preset first position information and/or to obtain the second comparison result; when the first comparison result and the second If any one of the comparison results is incorrect, decryption is refused; when both the first comparison result and the second comparison result are correct, decryption is performed.

The above method also includes: presetting the first location information and the second location information, and the physical feature information from the first location to the second location and saving them. Specifically, a password setting interface is provided to the user before decryption, and the password value input by the user is received and stored in the register.

Optionally, in step S105, it may also be: receiving the third position information determined by the user in the cycle graph; comparing the third position information with the preset third position information to obtain the second comparison result; when If any one of the first comparison result and the second comparison result is incorrect, the decryption is refused; when both the first comparison result and the second comparison result are correct, decryption is performed.

The third position may be any position different from the first position and the second position, or may be the same position as the first position or the second position.

Optionally, the first position and the second position may be the same position coordinates.

The above method is explained below by taking the circular dial as an example of a circular figure.

Different numbers of location information can be set according to the complexity of the password. Here, a circle containing 360 location information is used as an example. When the user selects the first location and the second location on the circular dial on the display screen, he can pass Move the pointer on the circular dial to adjust to point to a certain position, so as to accurately point to a certain point on the circle.

2 is a schematic diagram of a password authentication method for a circular dial in an embodiment of the present invention. As shown in FIG. The first position and the second position 102 are used to represent different values respectively; the physical feature information from the first position to the second position of position 1 and position 2 can be the perimeter, voltage, area, Angle, number of cycles.

When the first position information and the second position information are coordinates, the specific calculation methods of the first position coordinates and the second position coordinates of position 1 and position are the same, as follows: take the center of the circle as the origin coordinate (0, 0), circle The radius of the radius is 1, and the coordinate 1 in Figure 1 is the position point, then 360 points are all on the circle, and the coordinate of the coordinate i (the first position) is {(cos(2∏/360)*i), (sin( 2∏/360)*i)}, and the coordinate of coordinate j (the second position) is {(cos(2∏/360)*j, (sin(2∏/360)*j)}.

When operating in a safe payment or other password environment, the terminal first calls the touch screen operation, and displays the corresponding graphic dial and touch pointer on the display screen. Each direction indicated by the touch pointer corresponds to a position information. The user follows the memorized position information. Slide the touch pointer to the first position, click to confirm, and then rotate the corresponding number of circles to reach the second position. After clicking to confirm, the first position coordinates and the second position coordinates of the pointer on the touch screen at this time will be directly stored in the sender. The password is compared, and the number of rotations is compared with the preset number of rotations. When both are satisfied, decryption is performed. The above-mentioned first position coordinates and second position coordinates may be the same.

Optionally, the user can compare multiple locations to increase the security of the password. When the first position and the second position information and biometric information are compared successfully for the first time, the circular dial is reset, and then the second comparison is performed, or multiple pointers are used for comparison. The comparison process is the same as It is the same for the first time, and will not be repeated here.

Due to the introduction of multiple comparison information, the complexity of the password can be expanded cyclically, for example, it can be cycled multiple times. Check the complexity of the password, depending on the precision and the mechanism of the cycle. The complexity of the password is theoretically endless. The position 1, position 2, position n, and the corresponding number of turns that need to be recorded, assuming that the accuracy is m points, if Ordinary users can tolerate up to j circles, and the password complexity is: (m*j)n kinds of enumerative passwords.

Password complexity: If it is 2 location information, the user usually uses 5 circles, (5*360)2=3240000, this kind of password strength is higher than the complexity of our common 6-digit password: 106=1000000;

If there are 3 pieces of location information, the user usually uses 5 circles (5*360) 3 = 5832000000. With the number of locations, the number of user circles increases in series.

3 is a schematic diagram of a password authentication method for a square dial in an embodiment of the present invention. As shown in FIG. 3 , the square dial is evenly engraved with a plurality of numerical marks, the first position of position 1 and the second position 103 and the sum of position 2 and the second position. The second position and the second position 104 are respectively used to represent different values; the first position information and the second position information can be calculated using calculation methods in the prior art, and will not be repeated here.

Fig. 4 is the flow chart of the present invention based on sliding rheostat password authentication method, as Fig. 4, this method comprises:

In step S201: receiving the voltage at the first position and the voltage at the second position determined by the user in the voltage distribution graph corresponding to the resistance of the sliding rheostat; the voltage distribution graph as a whole is a circular graph and has a uniform numerical identification; specifically, (such as As shown in Figure 4) a sliding rheostat is set in the terminal, and the sliding rheostat is connected to both ends of the power supply. The voltage obtained by adjusting the resistance value can select a certain equal division and mark it in the voltage distribution graph.

In step S202: Acquire the movement track from the first position to the second position; specifically, a touch pointer can be set in the voltage distribution graph, and each direction indicated by the touch pointer corresponds to a voltage value, and the user will set the voltage value according to the memorized voltage value. The touch pointer slides to the first position, and rotates the corresponding number of turns to reach the second position. Or directly determine the first position and the second position by enlarging and displaying the value of each touch point of the user.

In step S203: according to the movement track from the first position to the second position, calculate the total voltage value from the first position to the second position; meanwhile calculate the total voltage value according to the number of rotations.

In step S203: compare the total voltage value from the first position to the second position with the preset total voltage value to obtain the first comparison result; compare the first position voltage with the preset first position voltage and the preset It is assumed that the voltages at the first position are compared to obtain a second comparison result. When any one of the first comparison result and the second comparison result is incorrect, decryption is refused; when both the first comparison result and the second comparison result are correct, decryption is performed. After the user clicks to confirm, the driver directly compares the voltage value of the first position and the voltage of the second position of the touch pointer of the touch screen with the stored voltage value of the first position and the voltage of the second position, and then compares the total voltage value with the preset voltage value. The set total voltage value is compared, and when it is satisfied at the same time, decryption is performed. The above-mentioned first position coordinates and second position coordinates may be the same coordinates.

Fig. 6 is a schematic diagram of the password authentication device based on the sliding rheostat of the present invention. As shown in Fig. 6, assuming that the supply voltage of the rheostat is 3.6V, the correct decryption method is to first move the touch pointer to 201, and operate to start decryption, at this time AD voltage sampling will record the voltage at this time. If it is 0.45V ((3.6V/360)*45), it means that the starting point is correct. If it is in other positions, due to the uniqueness of physical resistance voltage division, other voltages are no longer possible to be 0.45 V, it means the starting point is wrong. When the touch pointer moves to 202, the operation is confirmed and decrypted. At this time, the AD voltage will record the voltage at this time. If it is 1.35V ((3.6V/360)*135), it means that the ending point is correct. , if it is in other positions, due to the uniqueness of the physical resistance voltage division, other voltages are no longer possible to be 1.35V, which means that the termination point is wrong. At this time, only the decryption with correct end point and starting point meets the decryption requirements.

If it involves the number of turns of the cycle, since the AD has been sampling the voltage during the process, and adopts the operation method of starting and confirming decryption, the number of physical operation turns can be recorded at the bottom layer. For example, the decryption process is 0.45V ( Start decryption)...1.35V...0.02V...0.45V...1.35V (confirm decryption), then the password characteristics described here: start from 201 (assuming the starting point is 45 ohms) to 202 (assuming The starting point is at 135 ohms), the impedance of a directional resistor (90 ohms marked with the starting point) plus the operation of one circle (360 ohms).
