A special password inputting security terminal for the blind comprises a keyboard body 1, a push switch 1a, a photoresistor a2, a photoresistor b2a, sound emitting ports 2b, Braille buttons 3, connecting bolts 4, a front shielding mask 5, a pull handle 5a, a front limiting strip 5b, a front shielding mask edge 5c, a middle shielding mask 6, a middle limiting strip a6a, a middle limiting strip b6b, a rear shielding mask7 and a rear limiting strip 7a. As the Braille buttons are installed, the blind can conveniently and correctly use the small keyboard. The non-transparent shielding masks installed on the small keyboard can effectively shield the sight of other people. In order that the blind can input a password trustingly, the two photoresistors are further installed; when the front shielding mask edge presses the push switch, and the two photoresistors are not simultaneously shielded, loudspeakers installed in the sound emitting ports send a warning signal, and the warning signal is stopped when the shielding masks totally shield the sight of other people.
