Abstract: We propose a method that uses sequence of biometric identities, gestures, voice input, characters, symbols and pictures, for user authentication and verifications. So, user credential would be combination of “What he/she is and what he/she knows”. User can create credential sequence using either same biometric identity or combination of two or more different biometric identity types, plain characters, formatted characters, unformatted symbol, formatted symbol, unformatted picture and formatted picture where any of these credential sub-member may or may not be present in the sequence created as user credential.

Abstract: We propose a method that uses sequence of biometric identities, gestures, voice input, characters, symbols and pictures, for user authentication and verifications. So user credential would be combination of “What he/she is and what he/she knows”. Examples of biometric identities are finger prints, toe prints, knee scan, iris scan, palm vein and any other body parts' image or scan that uniquely identifies a person. User may use gestures of same or different types as part of the credential. Examples of characters are alphabets in any language, numbers and special characters like @, #, $, ˜, ! and any other available for input. Examples of Symbols and Picture are emoticons, emoji's, image, photo or drawing. Characters can be plain or formatted using formatting options of color, shading, font styles—bold, italic, underline, strikeout, superscript, subscript, font name, font size and other available formatting options.
