Description

Device and method for password input

A device and method for inputting a password, in particular, a device and method for preventing peeks by others when a password is input.

Information security is important in the promotion and popularization of information technology. Passwords are a common method used by information systems as a means of security protection to prevent unauthorized use of information system resources. We often encounter and are currently known. The problem that technology can't solve effectively is to input passwords in places where people come and go in public places, and the input of passwords is the first to be private, but it is really uncomfortable to enter passwords in public places, such as the public. The password authentication or password setting of the bank teller computer or ATM ATM is a process that most people will experience. When entering passwords in so many people's situations, the parties must be wary. They are worried that the passwords will be sneaked by others and often need to be concealed. However, after all, such password input is still unsafe, and it is easy for others to see and harm their own rights and interests. Although biometrics such as fingerprints and iris recognition are becoming more popular, fingerprint recognition devices are susceptible to sweat stains, and there are many common shortcomings, such as the fact that both have been copied and identified. Accuracy is not affected by many factors and can not reach 100%. Biometrics may be misinterpreted due to injury, illness or aging. Fingerprint collection, iris or other biological information may be identified by the collected information. The most important point of the protection law is the collection and establishment of these biological information and related systems, which are costly in the daytime, and the aforementioned biometric protection methods. In contrast, although the password protection method has the risk of the password being sneaked, the use of the present invention can effectively reduce the risk of the password being sneaked. The password protection is a protection method that has the advantages of low cost, 100% correctness, and no violation of the personal data protection law.

Although the online banking password input of some banks (such as Heku Shangyin) provides a password input method with no fixed keys, it is not input by the general keyboard, but a set of keyboard buttons is randomly displayed by the screen. The user clicks the keyboard button to enter the password, although it can prevent the Trojan from recording the contents of the key when using the keyboard to input the password and transmitting it to the hacker when the computer is implanted with the trojan. The password is leaky, but it is still not suitable for public use, because its keyboard button clearly indicates the character represented by each button. When inputting in public, as long as others watch the dynamics on the keyboard button Get a glimpse of the user's password.

The invention further provides a password input device with a line-of-sight tracking technology, which makes the password input more convenient and user-friendly, and also makes the password input more secure.

The main object of the present invention is to provide a secure password input method and apparatus, and more particularly to a technique for not revealing password information due to other people's peeks even if a password is entered in a large audience.

The invention discloses a device and a method for inputting a password, which can improve the privacy of the input when the password is input, and there is no doubt that the password is leaked even under the public. The main control module 10 includes a first communication unit 101 for communication with the input module 11, and a keyboard key pattern unit 102 for randomly generating keyboard keys. The bit pattern 1112 and the key position of the key input by the user, that is, the key string according to the used keyboard key pattern 1112, correspond to the original password 180, one loses The output unit 103 is configured to output the keyboard key pattern 1112 generated by the keyboard key pattern unit 102 to provide the user with knowledge and a second communication unit 104 to transmit the original password 180 corresponding to the keyboard key pattern unit 102 to the application. System 3. When the password is input, the keyboard is an unfixed key. When the password is input, the keyboard key pattern unit 102 generates a keyboard key pattern 1112 to determine the key position of each character, and the output unit then uses the keyboard key pattern 1112. The display is known to the user, and the user enters a password on the keyboard according to the displayed key position. The output unit is a high-private component, and the displayed information is only visible to the user, and the other person cannot see the content displayed from the outside. Therefore, even if the password is entered in the public, there will be no password leakage. Hey.

1 is a diagram of a practical application of the present invention. When the application system 3 needs to perform password input, the request password input device 1 securely retrieves the password input by the user, and then the password input device 1 transmits the retrieved password. The application system 3, which is a preferred embodiment of the present invention, includes a main control module 10 and an input module 11. The main control module 10 includes a first communication unit 101 and an input module 11 The communication use, a keyboard key style unit 102 is used to randomly generate the keyboard key pattern 1112, and the key position of the key input by the user, that is, the key string according to the keyboard key pattern 1112 used, corresponds to the original password, an output unit. The keyboard 103 is used to output the keyboard key pattern 1112 generated by the keyboard key pattern unit 102 to provide the user with knowledge and a second communication unit 104 to transmit the original password corresponding to the keyboard key pattern unit 102 to the application system 3. The first communication unit 101 is electrically connected to the keyboard key pattern unit 102, and the output unit is The keyboard 103 is electrically connected to the keyboard key pattern unit 102, and the second communication unit 104 is electrically connected to the keyboard key pattern unit 102. The input module 11 includes an input unit 112 for inputting a password, and a communication unit 111 for communicating with the main control module 10 to transmit the data input by the user to the main control module 10. 3 is an execution step of the present invention. First, in step S102, a keyboard key pattern 1112 is randomly generated by the keyboard key pattern unit 102 and transmitted to the output unit 103. The next step S103 is further performed by the output unit 103. The keyboard key pattern 1112 generated by the 102 is outputted so that the user knows that the input password is compared. Next, in step S104, the user can see the keyboard key pattern 1112 outputted in the previous step S103, and then refer to the keyboard key pattern 1112. The key position is input to the input unit 112, and then in step S105, the input key string is transmitted from the communication unit 111 of the input module 11 to the first communication unit 101 of the main control module 10, and then the main control unit is step S106. The first communication unit 101 of the module 10 passes the received input key string to the keyboard key pattern unit 102 to correspond to the original password according to the generated keyboard key pattern 1112. Finally, in step S107, the previous step S106 is performed. The corresponding password is transmitted to the application system 3 through the second communication unit 104. The keyboard 1111 of FIG. 4(a) can be implemented as one of the input units 111, but the keys on the keyboard are unfixed keys, that is, the same key is input at a different password, and the represented characters may be different. A new set of keyboard key patterns 1112 is generated by the keyboard key pattern unit 102 when the secondary password is entered to redefine the characters represented by each key. 4(b) and 4(c) show two aspects of the keyboard key pattern 1112. As the keyboard key pattern 1112 described above is generated in a random manner, there are actually many different keyboard key patterns. 4(b) and FIG. 4(a), the character represented by the button in FIG. 4(a) is determined by the corresponding position in FIG. 4(b), such as using the keyboard key of FIG. 4(b). For the style, the button in the top right corner of Figure 4(a) represents "0", and the button in the lower left corner is "*", but if the keyboard key pattern of Figure 4(c) is used, Figure 4(a) The button in the upper right corner represents "3" and the button in the lower left corner is "7". Since the keyboard 1111 is an unfixed key, the characters represented by the same key may be different at different times of input. When the user inputs the password on the keyboard 1111, the input is entered. The password is only represented by the key of the button, and the key can be represented by the number of the button. If a password contains 4 characters, it needs 4 key numbers. We call it a key string, as shown in Figure 4. (d) The number in the circle represents the number of the button, or the key or key number, and if the keys of the group are upper right, lower left, upper left, and lower right, the key string is 3,10. 1,12, if the keyboard key pattern 1112 of Fig. 4(b) is used, the corresponding password is "0&6#". The output unit 103 must be a private display or output information that can only be viewed or known by the user, but other people cannot see or know the components of the displayed content, as shown in FIG. 12, the output of the projector and the smart glasses. The component is a preferred embodiment of the output unit, and the output information is directly projected by the projector to the human eye, and the outsider cannot see the output content. The general smart glasses include a communication unit, an output unit, and a display unit, and the keyboard key style unit can design an App to perform its function. Therefore, the smart glasses are also a preferred embodiment of the main control module 10. Generally, only one communication unit can bear the communication with various accessories. Therefore, the first communication unit 101 and the second communication unit 104 of the main control module 10 can be combined into a communication unit 105 as shown in FIG. 5, wherein the communication unit 105 The keyboard key position unit 102 is electrically connected, the output unit 104 is electrically connected to the keyboard key pattern unit 102, and the communication unit 105 is responsible for communicating with the input module 11 and the application system 3.

The keyboard key pattern unit 102 is electrically connected to the communication unit 105, and the communication unit 105 uses the keyboard key pattern unit 102. The generated keyboard key pattern 1112 is transmitted to the output module 12, and is responsible for receiving the key data input from the input module 11, and when the password input is completed, it is responsible for transmitting the password to the application system 3. lose The input module 11 includes an input unit 112 for inputting a password, and a communication unit 111 for communicating with the main control module 10 to transmit the data input by the user to the main control module 10, and the input unit 112 and the communication The unit 111 is electrically connected. The output module 12 includes a communication unit 121 and an output unit 122. The communication unit 121 is electrically connected to the output unit 122. The communication unit 121 is configured to receive the keyboard key pattern 1112 transmitted from the main control module 10, and then The keyboard key pattern 1112 is output to the output unit 122. 7 is an execution step of the embodiment of FIG. 6. First, in step S202, a keyboard key pattern 1112 is randomly generated by the keyboard key pattern unit 102, and then the step S203 is further performed by the communication unit 105 of the main control module 10 to generate the generated keyboard. The key pattern 1112 is transmitted to the communication unit 121 of the output module 12, and the next step S204 is sent to the output unit 122 after the communication unit 121 of the output module 12 receives the keyboard key pattern 1112, and then the step S205 is based on the user. The input keyboard key pattern 1112 indicates that the password is input in the input unit 112 of the input module 11, and then the step S206 transmits the input key string to the communication unit of the main control module 10 by the communication unit 111 of the input module 11. 105. Then, in step S207, the received key string is sent to the keyboard key pattern unit 102 by the communication unit 105 of the main control module 10, and the keyboard key pattern 160 is generated according to the generated keyboard key pattern 160. Finally, the step is performed in step S208. The password corresponding to the step is transmitted to the application system 3 through the communication unit 105.

FIG. 8 illustrates a preferred embodiment of the present invention, including a main control module 10 and an output module 12. The main control module 10 includes a keyboard key pattern unit 102 for randomly generating a keyboard key pattern 1112. And the key of the button 170 input by the user is corresponding to the original key code 1111, the communication unit 105 is used for communication with the output module 12 and the application system 3, and the input unit 106 is used for input.

First, step S302 randomly generates a keyboard key pattern 1112 by the keyboard key pattern unit 102, and the next step S303 transmits the generated keyboard key pattern 1112 to the generated unit by the communication unit 105. After the output module 12, the communication unit 121 of the output module 12 receives the keyboard key pattern 1112 and then outputs the keyboard key pattern 1112 to the output unit 122, and then the step S305 is the keyboard key pattern 1112 displayed by the user according to the previous step. The instruction inputs a password at the input unit 106, and sends the input key string to the keyboard key pattern unit 102, and then the step S306 is performed by the keyboard key pattern unit 102 according to the generated keyboard key pattern 1112 in the previous step. The input key string corresponds to the original password, and finally the step S307 transmits the password corresponding to the previous step to the application system 3 through the communication unit 105.

The password input process of FIG. 3, FIG. 7 and FIG. 9 is slightly different according to the architecture of three different devices, but all have keyboard key pattern unit to randomly generate keyboard key pattern and output unit to output privacy. The data keyboard key pattern and the input unit are used for inputting a password, and the generation of the keyboard key pattern and the action of the password corresponding to the key string are completed on the password input device 1 in the application process, and the advantage is the password input. The device 1 has high independence, and all actions are completed on the password input device 1. The application system only needs to treat the password input device 1 as a keyboard, and does not need to modify the program. Another method is to leave the keyboard key pattern generation and the password corresponding to the key string to the application system 3. The original password input device 1 is only responsible for displaying the keyboard key pattern and allowing the user to input to obtain the key position. The string is then passed back to the application system 3 to correspond to the password. Therefore, the original password input device 1 is only responsible for the input and output work due to the function change, and the output and the input can be operated independently. Therefore, the input and output modules can be divided into two modules. FIG. 10 is a preferred embodiment of the above concept. The password input device includes an input module 4, an output module 5, and an application system 3. The application system 3 includes a first communication unit 31 and a keyboard key pattern unit 32. The keyboard key pattern unit 32 is responsible for generating a keyboard.

The string is passed back to the application system 3. The output module 5 includes a communication unit 51 and an output unit 52. The communication unit 51 and the output unit 52 are electrically connected. The communication unit is responsible for receiving the keyboard key pattern 1112 transmitted from the application system 3, and sending the received information. Output to the output unit 52. 11 is the operational flow of the embodiment. First, in step S402, a keyboard key pattern 1112 is randomly generated by the keyboard key pattern unit 32 of the application system 3. Then, in step S403, the first communication unit 31 of the application system 3 generates the generated The keyboard key pattern 1112 is transmitted to the output module 5. Then, in step S404, the communication unit 51 of the output module 5 receives the keyboard key pattern 1112 and outputs it to the output unit 52. The next step S405, the user according to the keyboard key position. The instruction of the pattern 1112 inputs a password in the input unit 42, and then in step S406, the communication unit 41 of the input module 4 transmits the key string input by the user to the first communication unit 31 of the application system 3, and finally the step S407 is further applied by the application system. The first communication unit 31 of 3 hands the received key string to the keyboard key pattern unit 32 to correspond to the original password according to the generated keyboard key pattern 1112.

All the above communication units can use communication technologies such as Wifi, Bluetooth, 3G, 4G, USB, RS232, GPRS, twisted pair, coaxial cable, RS485 and IEEE1394, and as long as the two components can communicate with each other, the invention is Covered by the communication unit, it is not limited to the communication technologies listed above.

The second communication unit 81 of the control module 8 receives the keyboard key pattern and sends it to the output unit 82 and outputs it. Then, in step S604, the password input can be performed. The input mode is that the user looks at the line of sight at the output unit 82. On the displayed password key on the keyboard key pattern, the line-of-sight tracking module 74 tracks the user's line of sight to obtain the position that the user inputs the password character, and displays the position with the displayed keyboard key. The bit pattern corresponds to find the key number to be watched, and each password character is gazing in the same line of sight to input a password, and then the key number of each input password character is combined to obtain a key bit string, and then Step S605 hands the key string to the second communication unit 81 and transmits it back to the application system 3. Finally, step S606 is passed to the keyboard key pattern unit 32 after the first communication unit 31 of the application system 3 receives the key string. The key string received will be corresponding to the original password by the keyboard key pattern 1112 of the input.

In order to prevent the keyboard key pattern generated by the keyboard key pattern unit 32 from being eavesdropped during the communication process, FIG. 24 is a modification of the structure of FIG. 19 to prevent the keyboard key pattern from being eavesdropped during the communication process, including a main control module. 8 and an application system 3, the application system 3 includes at least a first communication unit 31, a style selector 34, and a first keyboard key pattern library 35. The first communication unit 31 is responsible for communicating with the main control module 8, and The style selector 34 selects (either randomly or otherwise) a keyboard in the first keyboard key style library 35 The key pattern is transmitted to the main control module 8 through the first communication unit 31. The main control module 8 includes a second communication unit 81, an output unit 82, a second keyboard key pattern library 83, and a The line-of-sight tracking module 74, the second communication unit 81 is responsible for communicating with the application system 3, the output unit 82 is for outputting the keyboard key pattern, and the second keyboard key pattern library 83 is for receiving the keyboard received by the second communication unit 81. The key pattern number provides the keyboard key pattern corresponding to the number to the output unit 82. The structure of the line-of-sight tracking module 74 is as shown in FIG. 16 including a camera 741 and a line-of-sight tracking unit 742. The camera is responsible for capturing the eye movement of the user. Then, the captured image is sent to the gaze tracking unit 742 for analysis of the gaze gaze position, so the entire gaze tracking unit 742 is responsible for acquiring the focus of the user's line of sight, and converting the gaze position into the output unit 82. The button position of the output keyboard key pattern, that is, the key string, is transmitted back to the application system 3, and the application system 3 receives the returned key string, and then presses the style selector 34. Pattern selection keys of the keyboard number keys and a first keyboard keys to bit pattern library 35 corresponding to the number of the keyboard keys to receive the bit pattern data string converted into the real input. The keyboard key style library added by the main control module 8 and the application system 3 all store multiple sets of keyboard key styles and are respectively given numbers. The two keyboard key style libraries should be synchronized, that is, the data must be consistent, and the data can be collected. The time synchronization or update can be copied to the application system 3 by the main control module 8 or copied to the main control module 8 by the application system 3. The operation process is first selected by the style selector 34 (randomly or otherwise) a keyboard key pattern in the first keyboard key pattern library 35. In the next step, the first communication unit 31 will select the selected keyboard key. The bit pattern number is transmitted to the main control module 8. In the next step, the second communication unit 81 receives the transmitted keyboard key pattern number and hands it to the second keyboard key pattern library 83, and then the second keyboard key position. The style library 83 provides the keyboard key pattern corresponding to the number to the output unit 82 by the keyboard key pattern number received by the second communication unit 81, and the output unit 82 outputs the keyboard key pattern after receiving the keyboard key pattern, and then the user Looking at the character in the keyboard key pattern output by the output unit 82, in the next step, the line-of-sight tracking module 74 analyzes the user's position according to the position of the user's line of sight. To input the position of the character and convert it into a key string and hand it to the second communication unit 81, then the second communication unit 81 transmits the key string to the first communication unit 31 of the application system 3, and then by the first communication unit. 31 passes the received key string to the style selector 34. Finally, the style selector 34 converts the key string into the actual input data according to the selected keyboard key pattern.

FIG. 21 is another device for inputting a password in a line-of-sight tracking manner. The difference from FIG. 19 is that the output unit 82 in the main control module 8 is moved to the application system 3, and is transferred to become the output unit 33 of the application system 3. The main control module 8 becomes the line of sight input module 9. The system includes an application system 3 and a line-of-sight input module 9. The application system 3 is a system that requires password input, and includes at least a first communication unit 31 for communicating with the line-of-sight input module 9, and a keyboard key pattern unit. 32 provides (available randomly or otherwise) the keyboard key pattern and the key string returned by the line of sight input module 9 corresponding to the original password, and an output unit 33 for outputting the keyboard key pattern, the line of sight input module 9 The communication unit 91 is configured to communicate with the application system 3 and a line-of-sight tracking module 74 for interpreting the keyboard key pattern output by the user using the line-of-sight gaze output unit 33. The character to be watched is the password to be input, and the line of sight is The architecture of the tracking module 74 is as shown in FIG. 16 including a camera 741 and a line of sight tracking unit 742. The camera is responsible for capturing the eye movement of the user, and then passing the captured image to the line of sight tracking unit 742 for analysis of the line of sight gaze position. Therefore, the entire line of sight tracking unit 742 is responsible for acquiring the focus of the user's line of sight and converting the position of the view to the keyboard key sample output by the output unit 33. The key position. The keyboard key pattern unit 32 is electrically connected to the first communication unit 31 and the output unit 33, and the line-of-sight tracking module 74 of the line-of-sight input module 9 is electrically connected to the communication unit 91. FIG. 22 is a flow chart of the password input of the device of FIG. 21. First, step S702 provides a keyboard key pattern by the keyboard key pattern unit 32 and delivers it to the output unit 33 and outputs it. Next, step S703 can perform password input and input. The method is that the user looks at the password character key to be input on the keyboard key pattern output by the output unit 33, and the gaze tracking module 74 tracks the user. Sight to obtain the position that the user enters the password, and convert the position to the key number on the keyboard key pattern. Each password character is gazing at the same line of sight to enter the password, and then each password is entered. The key number of the character is combined to obtain a key bit string, and then the step S704 passes the key bit string to the communication unit 91 for transmission back to the application system 3. Finally, the first communication unit 31 of the application system 3 receives the key position in step S705. The string is then passed to the keyboard key pattern unit 32 and the received key string is mapped to the original password by the keyboard key pattern 1112 of the input.

In general, the gaze tracking technology usually needs to be corrected by the positioning correction function to obtain the position of the line of sight. Another method is as shown in Fig. 23: an infrared ray emitter 743 is added to the gaze tracking module 74 to illuminate the cornea as a positioning reference. It can improve the accuracy of positioning and save the calibration time. At the same time, the camera 741 must have the ability to record the infrared light emitted by the infrared emitter 743. In general, some cameras can record infrared rays, but they also add a filter in front of the lens. Infrared filter, a simpler method is to remove the infrared filter to record infrared. After the line of sight tracking module 74 calculates the direction of the user's line of sight, the position of the line of sight and the line of sight can be utilized to derive the position of the line of sight.

Generally, the gaze tracking displays the selection information on a general screen or a large screen. The user can infer the information input by the user by watching the user's eyes and the screen or the large keyboard key style. The present invention will use the keyboard key. The bit style is displayed on the smart glasses. Unlike the general line of sight tracking input, because of the relationship between the glasses and the glasses, the other people can not only see the user's eyes, they can not see the keyboard key style displayed on the glasses. Even if the display area of the glasses is reduced or the opaque material is selected as shown in FIG. 12, the display area of the glasses cannot be viewed from the outside, so that the password input is more secret, and it is less likely to be peeked, thereby improving the security of the password input.

The so-called random generation of the keyboard key pattern 1112 causes the characters represented by the keys of the keyboard 1111 in FIG. 4 to be randomly assigned, and is not fixed. In addition, the key string corresponds to the original password. That is, the number of each key in the key string is numbered, and the key password is corresponding to the original password in the keyboard key pattern 1112 used for the input. The application system 3 generally refers to a system that requires password input, such as a bank teller system, an ATM, a stock service system, an accounting system, a personnel salary system, and the like that require a password input system.
