摘要:
The invention provides a solution for secure authentication of an individual. The invention comprises methods and apparatus for secure input of a user's identifier e.g. PIN. An image of a keypad is superimposed over a scrambled, operable keypad within a display zone of a screen associated with an electronic device. The keypad image depicts a non-scrambled keypad, in that the keys depicted in the image are in an expected or standardised format or order. The difference in positions of the keys depicted in the image, and those in the operable keypad, provides a mapping which enables an encoded form of the identifier to be generated, such that the un-encoded version is never stored in the device's memory. Preferably, the image depicts a keypad which is standard for the device which it is being shown on. The device may be a mobile phone, a tablet computer, laptop, PC, payment terminal or any other electronic computing device with a screen. The underlying keypad, which is at least partially obscured from the user's view by the image, may be generated at run time by a procedure call. Preferably, this procedure is native to the device ie part of a library which is provided as standard with the device.

The invention provides an authentication method and system. It is particularly suited for verifying the identity of an individual prior to permitting access to a controlled resource. This may or may not be a financial resource. The invention uses biometric data relating to a user to encode and decode an identifier associated with a user. Thus the user's biometric data becomes the key for encoding and subsequently decoding the identifier. In one embodiment, the biometric data is used to generate a keypad configuration. The keypad configuration specifies the order and/or position of a plurality of keypad keys. An operable keypad and/or image of a keypad is then generated using the configuration. Thus, the individual's biometric data can be used to generate a customised keypad and/or image which can then be used to encode or decode the identifier associated with the user. A keypad or image generated from the biometric data can be used to generate a mapping between different keypad configurations. The biometric data may be captured at or on a device associated with the individual, such as a computer, mobile phone, tablet computer etc.

A method of controlling a graphical user interface, GUI, of an electronic device. The GUI is defined by a GUI definition document processed by the electronic device. The GUI definition document defines a layout of the GUI for rendering the GUI, navigable elements of the GUI, at least one navigation event, and at least one navigation data set per navigable element, wherein a navigation data set specifies for a respective one of the at least one navigation event a next one of the navigable elements to be navigated to in response to the navigation event. The method includes rendering, by the electronic device, the GUI according to the layout; and navigating from a current navigable element to a next navigable element by receiving, by the electronic device, a navigation event, and in response to the received navigation event, setting, by the electronic de-vice, the current navigable element as inactive and the next navigable element as active for user interaction, wherein the next navigable element being determined based on the at least one navigation data set of the current navigable element.

Embodiments of the invention provide an improved keyboard-based navigation system for menu-based operating systems and desktop applications. An embodiment provides a drop-down (or pull-down) menu interface operated by providing the keyboard function keys, i.e. keys not assigned to a specific ASCII printable code, with context-driven functionality, i.e. where the operation caused by the press of a given function key depends on the state of the menu interface (e.g. the active portion thereof) at the time the function key is pressed. An embodiment provides a GUI having an application switch interface comprising a tiled display, wherein each tile has a function key associated with it, and wherein each open application is assigned to a tile to enable a user to switch to an open application by selecting the corresponding function key.
