Abstract

User authentication methods for use within an augmented reality (AR) headset can be difficult to use due to the nature of a headset. Without buttons, keypads or a touch screen, it is difficult for the user to provide input to an authentication method such as a PIN or password. This publication describes an authentication method suitable for use within an AR headset to increase usability.

A dynamic authentication method for use within an Augmented Reality headset

Augmented reality headsets (either currently or in future development) allow the user to select objects on the display using eye movements, moving their hands in front of the display, or pressing buttons on the side of the device. It is clear why standard authentication methods originally designed for computers or mobile devices would be more difficult for a user trying to authenticate on an AR headset. Other methods, such as the user moving their hands to type on a virtual keyboard, or mimicking a keypad in the air would be easier for the user to use for entering a PIN or password, but could allow an onlooker to work out what the user is typing due to the movement and positioning of their hands. These methods would take the user a relatively lengthy amount of time to input, which is not ideal since the overlay in the glassware display is likely to be in their direct line of sight and may potentially block the user from seeing sections of the real world.

    A dynamic method is required that is designed for use within an AR headset and must be quick and easy for the user to authenticate without compromising security. A new method should utilise the fact that the authentication method will be displayed directly in front of the user's eyes, so would suit a visual dynamic method of authentication by which the user could quickly provide a correct answer without onlookers being able to replicate their answer.

Current authentication methods used are:

    1) http://ip.com/pat/WO2014071332A1 This patent describes using a virtual reality environment such as a virtual living room in which the user must go around and look/touch certain objects in a certain order as their 'password'. This method is not suitable for use within augmented reality as the environment is the real world which is continuously changing. This could work with AR glasses used for gaming where the device is in a room that is unlikely to change much, but for other situations this is not suitable.

    2) http://cups.cs.cmu.edu/soups/2014/workshops/papers/voice_bailey_20.pdf This article describes the benefits and problems for multiple methods of authentication within AR devices, detailing the issues around textual and PIN based passwords within AR and why photo based authentication methods are more suited.

    AR glassware devices generally have a front facing camera which shows the world from the user's perspective and is used to determine the positions of informative overlays on the display. This idea makes use of this 'point of view' camera, and would store snippets or images of the video stream received from this camera.

    Using this stored camera feed, when the user is required to authenticate, the device would prompt the user with a context based question about an occurrence in their life within the last few days. The user would be shown images which they must select from, or they must provide an answer verbal...
