As the requirement for companies and individuals to protect information and personal details comes more into focus, the implementation of security that goes beyond the ubiquitous password or Personal Identification Number (PIN) is paramount. With the ever growing number of us utilizing more than one device simultaneously, the problem and need is compounded. This paper proposes a novel approach to security that leverages the collective confidence of user identity held by the multiplicity of devices present at any given time. User identity confidence is reinforced by sharing established credentials between devices, enabling them to make informed judgments on their own …

In this report the results of applying a three dimensional range imaging system, based on coded structured light, are presented. This includes a description of a new improved spatial coding scheme. This new scheme increases the number of reference points available and provides a basis for more accurate calculation of their location. A detailed description of the image processing methods used to extract structural information and to identify structural objects from the camera image are given. In addition the method used to calculate the locations of reference points with 'subpixel' accuracy is described. Finally, the results of experiments with synthesised …
