First Claim
Patent Images
1. A method of access control in an electronic device, the method comprising:
- receiving input at the electronic device;
when the input is received from a key of a keyboard, identifying a Unicode character that is associated with the key and adding the Unicode character that is associated with the key to a passcode;
when the input is a gesture, identifying a Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard, and adding the Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard to the passcode; and
determining whether the passcode matches a previously set passcode that includes the Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard; and
changing an access state at the electronic device when the passcode matches the previously set passcode.

Abstract
A method of access control in an electronic device includes monitoring for input at the electronic device, for each input determined to be one of a plurality of predefined gestures including gestures from a touch-sensitive input device or from a movement sensor, mapping the input to a respective Unicode character and adding the respective Unicode character to a passcode to provide an entered passcode, comparing the entered passcode to a stored passcode, and changing an access state at the electronic device if the entered passcode matches the stored passcode.

12. An electronic device comprising:
-
input devices, a memory and a processor coupled to the input devices and the memory to execute a program stored in the memory to cause the electronic device to; receive input from the input devices, when the input is received from a key of a keyboard, identify a Unicode character that is associated with the key and adding the Unicode character that is associated with the key to a passcode; when the input is a gesture, identify a Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard, and adding the Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard to the passcode; and determine whether the passcode matches a previously set passcode that includes the Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard; change an access state at the electronic device when the passcode matches the previously set passcode. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable medium having computer-readable code stored thereon, the computer-readable code executable by at least one processor of an electronic device to:
-
receive input; when the input is received from a key of a keyboard, identify a Unicode character that is associated with the key and add the Unicode character that is associated with the key to a passcode; when the input is a gesture, identify a Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard, and add the Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard to the passcode; determine whether the passcode matches a previously set passcode that includes the Unicode character that is unused for any other character encoding and that cannot be typed using the keyboard; and change an access state at the electronic device when the passcode matches the previously set passcode.
