Abstract:
A method of converting input signals into character codes in a data processing system, said method comprising:receiving a password, wherein said password includes at least one character code and at least one time-span code; receiving a first input-event signal, wherein said first input-event signal comprises one of a key-up signal from said keyboard and a start signal from a program capable of processing said character code and said time-span code; receiving a second input-event signal after an interval of time has elapsed since said first input-event signal was received, wherein said second input-event signal comprises one of a key-down signal from said keyboard and an entry-complete signal from said program; in response to said second input-event signal, generating a character code and a time-span code when said interval has a duration greater than a predetermined pause duration, said time-span code corresponding to a duration of said interval; and confirming that the generated character code and time-span code matches the at least one character code and at least one time-span code, respectively, of the password.
