Abstract

The invention relates to a shoulder surfing resistant security password input method on a smart phone, belonging to the information security field. The method designs a password input interface and apassword input method, and supports password input containing one or more symbols of digits, upper and lower case letters and special characters. The method uses familiar 12 Chinese zodiac signs as input markers, and the randomly assigned Chinese zodiac signs are used as input markers to input fuzzy passwords. The attacker could not obtain the correct passwords through shoulder surfing, so the attacker could resist shoulder surfing attacks effectively. The invention is applicable to various password inputs of smart phones in daily life.
