Secure system for non-covert user authentication and identification

An authentication interface for entering a user passcode comprising:

• a display displaying a character dial, the character dial including a set of available characters that a user may select to enter the passcode;
• the display displaying a plurality alignment markers;
• a passcode input module receiving a user command to move the character dial in relation to the alignment markers;
• the passcode input module operable to receive a command to record alignment configuration data defined by the alignment of the character dial with respect to the alignment markers and to communicate the alignment configuration data to a passcode generation module, the alignment configuration data including at least one available character and at least one alignment indicator position value indicative of the position of one of the characters with respect to one of the alignment indicators;
• and
• the passcode generation module operable to generate at least one passcode hypothesis based on said alignment configuration data, the passcode hypothesis including at least one character selected by the user and at least one alignment marker position value corresponding to one of the characters in the passcode hypothesis.

A system for authenticating a user in a conspicuous environment comprising:

• a display displaying a substantially circular wheel having and a predetermined amount of alignment markers located along a peripheral edge of the wheel;
• the display module displaying a substantially circular character dial having a predetermined amount of available characters located along a peripheral edge said character dial, wherein said character dial is concentric with the wheel and wherein the amount of alignment markers is equal to the amount of characters;
• the character dial rotatable about its center with respect to the alignment markers;
• a passcode input module operable to receive user commands, wherein said user commands include rotating said character dial;
• the passcode input module operable to record alignment configuration data, the alignment configuration data defined by the alignment of the character dial with respect to the alignment markers, wherein the alignment configuration data includes at least one character and at least one alignment marker position value representing the position of a character with respect to an alignment marker;
• a passcode generation module receiving the alignment configuration data operable to generate a passcode hypothesis having at least one character and one alignment marker position value based on the received alignment configuration data;
• a data store storing authentication data including at least one stored passcode, a stored passcode including at least one character and at least one alignment marker position value;
• and
• an authentication module in data communication with the data store, the authentication module operable to receive the passcode hypothesis and to authenticate the user when the passcode hypothesis matches one of the stored passcodes.

A system for authenticating a user comprising:

• a display displaying an authentication interface;
• the authentication interface having a plurality of available characters in fixed positions and a plurality of alignment markers, the alignment markers movable with respect to the available characters;
• a passcode input module operable to receive a user command to move the alignment markers in relation to the available characters and to receive a user command to record alignment configuration data defined by the alignment of the alignment markers with respect to the available characters, wherein alignment configuration data includes at least one available character and at least one alignment marker position value indicative of an alignment marker corresponding to one of the available characters;
• said passcode input module further operable to communicate said alignment configuration data to passcode generation module;
• the passcode generation module operable to generate at least one passcode hypothesis from the alignment configuration data, said passcode hypothesis comprised of at least one character and at least one alignment marker position value;
• a data store storing authentication data including at least one stored passcode, a stored passcode including at least one character and at least one alignment marker position value;
• and
• an authentication module in data communication with the data store, the authentication module operable to receive the passcode hypothesis and to authenticate the user when the passcode hypothesis matches one of the stored passcodes.
