Consider in prior art, when user inputs password on intelligent terminal, the button coordinate information that can directly user be inputted by terminal handler converts encrypted message to, so it is likely to the button coordinate information being obtained the distribution of dummy keyboard on intelligent terminal by rogue program and when user inputs password, thus obtaining the encrypted message of user, cause that user password information is revealed。Based on this, this utility model embodiment provides a kind of cryptosecurity input equipment based on touch screen。It is described by the examples below。
Embodiment
This utility model embodiment provides a kind of cryptosecurity input equipment based on touch screen。On each intelligent terminal, all having a terminal handler, this terminal handler is connected with the touch screen module of this intelligent terminal, receives the various command signals that user is transmitted by touch screen module, processes accordingly。
The cryptosecurity input equipment based on touch screen that this utility model embodiment provides, as it is shown in figure 1, include terminal handler 110, simulating Safety switch 120, touch screen module 130 and safe processor 140。
Safe processor 140 switchs 120 with terminal handler 110 and simulating Safety respectively and is connected；
The control signal of simulating Safety switch 120 reception safe processor 140 transmission, to switch the first data channel and the second data channel, first data channel is the data channel between terminal handler 110 and touch screen module 130, and the second data channel is the data channel between safe processor 140 and touch screen module 130；
Safe processor 140 receives the Password Input request of terminal handler 110 transmission, and transmission of control signals switchs 120 to simulating Safety, simulating Safety is switched 120 and switches to the second data channel；And resolve the password key coordinate information that user inputs, obtain the encrypted message of user's input, and be transferred to terminal handler 110 after the encryption of this encrypted message。
When user need not input password, simulating Safety switch 120 unlatching is the first data channel, the namely data channel between terminal handler 110 and touch screen module 130, at this moment, it is the command signal that inputs on the touchscreen of the user transmitted to receive touch screen module 130 by terminal handler 110 or information, and processes。
When user uses Alipay, the means of payment on the intelligent terminal such as wechat or Mobile banking pays, or brush bank card, or log in the application program on intelligent terminal, when needing input password, terminal handler 110 on above-mentioned intelligent terminal can transmit Password Input request to safe processor 140, after safe processor 140 receives the Password Input request of terminal handler 110 transmission, control signal can be sent according to the Password Input request received and switch 120 to simulating Safety, after simulating Safety switch 120 receives the control signal of safe processor 140 transmission, data channel can be switched to the second data channel, so-called second data channel is exactly the data channel between safe processor 140 and touch screen module 130。At this moment, when the screen of user's touch intelligent terminal, command signal or the information that user inputs can be transferred to safe processor 140 by touch screen module 130, processed by safe processor 140, and terminal handler 110 will not receive command signal or the information of user's input that touch screen module 130 transmits。
After safe processor 140 receives the Password Input request of terminal handler 110 transmission, also the password key coordinate information of user's input can be resolved, thus obtaining the encrypted message of user's input, and after this encrypted message is encrypted, it is transferred to terminal handler 110, by terminal handler 110, the encrypted message after encryption is transmitted the background server to this intelligent terminal, by background server, this encrypted message is authenticated, after encrypted message certification is completed by background server, authentication result can be transferred to terminal handler 110, terminal handler 110 carries out further work according to above-mentioned authentication result, if background server sends the authentication result that this encrypted message is correct, then terminal handler 110 can send the correct information of password to safe processor 140, control signal can be sent by safe processor 140 and switch 120 to simulating Safety, switched 120 by simulating Safety and above-mentioned data channel is switched to the first data channel, the namely data channel between terminal handler 110 and touch screen module 130, at this moment command signal or the information of user's input that touch screen module 130 transmits just is received by terminal handler 110, safe processor 140 then no longer receives the user input data of touch screen module 130 transmission, these data can for the instruction of user's input, it can also be the out of Memory that inputs of user；If background server sends the incorrect authentication result of this encrypted message, then terminal handler 110 can send prompting, and prompting user re-enters password。
The cryptosecurity input equipment based on touch screen that this utility model provides, when user needs input password, safe processor can receive the Password Input request of terminal handler transmission, then send control signal to switch to simulating Safety, open the data channel between safe processor and touch screen module, and the encrypted message of user's input that safe processor is to parsing is transmitted further to terminal handler, improves the safety of input user password information after being encrypted。
