    摘要： Aspects of the present invention provide an approach for user authentication during a user session which potentially requires multiple user authentications. A library of authentication methods is provided for preforming the user authentications. For authentication, a threshold contribution value is set which needs to be exceeded for authentication to occur. To carry out the authentication, a chain of authentication methods is constructed at run time, selected from the library in order to provide an aggregate contribution value which exceeds the threshold. During run time, the contribution value of each authentication method is dynamically adjusted, so that construction of the chain uses current amounts for the contribution values of each authentication method. This allows the chain to be reconstructed at run time taking into account changing circumstances. Specifically, not yet executed authentication methods may be unlinked from the chain and replaced with one or more new ones.

    摘要： Proposed is a display control system for an augmented reality, AR, display system, the AR display system comprising a transparent display area adapted to augment an object or scene viewable through the transparent display area by displaying a visual element in the transparent display area. The display control system comprises: a focal point detection unit adapted to determine a point of focus of a user; and a processing unit adapted to determine an offset distance by which the determined point of focus of the user is spaced from the transparent display area, and to generate a control signal for modifying the transparency of the visual element based on the determined offset distance.

    摘要： Disclosed is a method for providing a user access to a computer system comprising a plurality of services and a plurality of authentication levels, the method comprising dynamically monitoring a risk profile of a user authenticated on said computer system; dynamically selecting an authentication level for each of said services based on said monitored risk profile; and if said authentication level for a service is higher than an actual authentication level for said user, sending a further authentication request to the user requesting the user to provide authentication information corresponding to the dynamically selected authentication level upon said authenticated user requesting access to said service.
