<p>A system for providing user authorisation to access clients, each client having an associated security level. At least one data input device is provided, each data input device being capable of providing user data relating to a user desiring access to a client, wherein different data input devices have different associated confidence levels. A user authorisation module, in communication with the plurality of clients and one or more data input devices, performs a user authorisation for a particular user based on the user data provided by one or more data input devices, wherein the user authorisation module compares received user data with stored reference user data and determines, when there is a match between the received user data and the stored reference user data within predetermined limits, a security level for the user dependent on the confidence level of each data input device from which the received user data is received. The user is then granted access only to those clients that have a security level at or below the security level determined for the user from the received user data.</p> |
