<p>A peep-preventing password keyboard and a method for inputting a password based on pressure sensing are provided. The keyboard comprises a case, a number key (21) and an ENTER key (22) exposed on the upper surface of the case, and a circuit system (5) installed in the case. The circuit system comprises a micro processor (51), a pressure sensor (52) and a display screen (3) coupled to the micro processor. The number key cooperates with the pressure sensor. The method for inputting a password includes: step a. the micro processor transforms the pressure applied on the number key to a number and displays the same on the display screen, until the ENTER key is pressed down to obtain a number input; step b: the micro processor judges whether the numbers having the specified length of the password are inputted, if so, the password input is finished; and if not the method returns to step a to input the next number. This solution can greatly improve the safety degree of inputting a password in public places.</p> |
