Random location authentication

摘要

An authentication string, such as a password, consists of characters. Each of the characters in the authentication string is randomly associated with a defined location on a device. For example, an area on a touch screen can be associated with a character in the authentication string. When a user selects a location associated with the character, feedback is provided that identifies the character. When the user selects a location that is not associated with the character, feedback is provided that does not identify the character.;If the user responds by indicating that the associated location matches the character, the character is authenticated. If the user responds by indicating that a location not associated with the character is a match, the character is not authenticated. This process is then repeated for each character in the authentication string.
