when a user places the RFID card in the RFID card reading prompt image, the processor acquires RFID antenna signals, obtains card data according to the RFID antenna signals, and sends the card data to the host through the USB.
The implementation principle of the embodiment of the invention is as follows:
because the transparent screen is integrated with a touch function and an RFID antenna function, the main board is integrated with a national security chip, an RFID card reading chip and a processor, a password input request sent by a host computer is received at the processor, password keyboard image data is generated according to the password input request, the password keyboard image data is sent to the transparent screen, so that the transparent screen displays the password keyboard image, when a user touches the password keyboard image, the processor acquires touch coordinates of the user, the touch coordinates are converted into key data, the processor calls the national security chip to encrypt the key data, ciphertext data is obtained, and the ciphertext data is sent to the host computer through a USB; or the processor receives an RFID card reading request sent by the host, generates RFID card reading prompt image data according to the RFID card reading request, and sends the RFID card reading prompt image data to the transparent screen, so that the transparent screen displays the RFID card reading prompt image. Compared with the existing screen integrated password input function, the under-screen password keyboard and the RFID card reading device integrate password input and RFID reading functions, password encryption is realized through the national password security chip, only ciphertext data and card data need to be transmitted to the host, and the risks of stealing password information by methods such as screen recording, screen capturing, input coordinate acquisition and the like on the host side are effectively prevented.
Preferentially, when the national security chip is called for encryption, in order to improve the security of the encryption, the secret key can be imported at any time, the processor receives a secret key perfusion instruction sent by the host, the secret key to be imported can be determined according to the secret key perfusion instruction, and the processor imports the secret key to the national security chip through the flat cable.
Preferably, the main board further comprises an anti-dismantling contact;
when the main board is installed, the anti-disassembly contact is contacted with the display screen shell;
the national security chip comprises a tamper detection pin, and the tamper detection pin is electrically connected with the tamper contact;
the anti-disassembly detection pin is used for detecting whether the anti-disassembly contact is in contact with the display screen shell or not;
when the tamper-proof detection pin detects that the tamper-proof contact is not in contact with the display screen shell, the tamper-proof security chip deletes the stored secret key.
In this embodiment, since the password input and encryption functions of the under-screen password keyboard and the RFID card reader are independent of the outside of the terminal host, the risk of stealing password information by methods such as screen recording, screen capturing and input coordinate acquisition on the host side is avoided, but the risk of password leakage may still exist on the under-screen password keyboard and the RFID card reader side, so that the anti-disassembly detection function is added, as shown in fig. 4, when the under-screen password keyboard and the RFID card reader are installed, the anti-disassembly contact 401 under the motherboard 103 is in contact with the display screen shell 203, the anti-disassembly detection pin of the national security chip is electrically connected, if the under-screen password keyboard and the RFID card reader are physically damaged, the anti-disassembly detection pin of the national security chip can detect that the anti-disassembly contact 401 is not in contact with the display screen shell 203, and at this time the national security chip deletes the stored secret key, thereby ensuring that the secret key cannot leak, and further ensuring the security of ciphertext data.
Preferably, in the above embodiment, only the password keyboard is described as being displayed on the transparent screen, but for increasing security, an out-of-order function is also required, which is specifically as follows:
the processor determines a password digit N and the total number M of key numbers of the password keyboard according to the password input request, wherein N and M are positive integers larger than 2; in general, according to the existing default habit, the number of the password digits is usually a value of 0-9 of 6 digits, and the total number of key numbers of the password keyboard is 10;
the processor sets first display coordinates of all key numbers corresponding to the first password, wherein the first display coordinates represent the display positions of the corresponding key numbers on the transparent screen;
the processor sends the first display coordinates to the transparent screen, so that the transparent screen displays the image of the password keyboard corresponding to the first password;
when a user touches a password keyboard image corresponding to the first password, the processor acquires a first touch coordinate of the user, and compares the first touch coordinate with a first display coordinate to acquire the first password;
the processor sets the N display coordinates of all key numbers corresponding to the N passwords in an disordered mode, so that the password keyboard images corresponding to the adjacent two passwords displayed on the transparent screen are different.
The specific disorder mode can be random or can be set according to a fixed disorder mode, and the purpose of the disorder mode is to enable all key numbers to disturb positions after a user clicks one password on a password keyboard image each time and display the positions to the user again, so that the password can be effectively prevented from being obtained by others through peeping, guessing or trace detection when the user inputs the password.
Preferably, when the user inputs the password, in order to prevent the user from peeping or monitoring the password, a screen peeping-proof function can be further introduced, which is specifically as follows:
the peep-proof monitoring system is arranged above the terminal, and can be a camera;
when the peep-proof monitoring system monitors that other users exist in the preset range of the current user of the terminal, the processor receives a password key peep-proof instruction sent by the peep-proof monitoring system; the preset range can be equal distance values of 1 meter apart, and when a user operates the financial equipment to input the password, other people are very close to each other, so that the password can be seen in a peeping manner; therefore, the peep-proof monitoring system is arranged above the terminal, and once a user inputs a password at the terminal, the peep-proof monitoring system monitors that other people exist within 1 meter, sends a password key peep-proof instruction to the processor and triggers the peep-proof function;
the processor generates brightness data and contrast data according to the password key peep-proof instruction; the brightness data and the contrast data are used for adjusting the image of the password keyboard, and the aim is to enable only the front side to directly see the image of the password keyboard by adjusting the brightness and the contrast, so that people nearby can be prevented from peeping the input password, and the effect is good when the brightness is 30nit and the contrast is 50:1;
and the processor adjusts the password keyboard image displayed by the transparent screen according to the brightness data and the contrast data.
It should be noted that, the adjustment of brightness and contrast needs to be adjusted on the transparent screen, so that the adjustment is only needed when the peep-proof mechanism is triggered, and the adjustment is only needed when the peep-proof mechanism is not triggered.
