MULTI-TOUCH SURFACE AUTHENTICATION USING AUTHENTICATION OBJECT

摘要

The invention relates to a system (102) for user authentication, particularly suited for authentication of groups of users in hospital environments. The system (102) comprises an authentication object (104) provided with a predefined geometrical pattern (106) for authenticating the user. The system (102) furthermore comprises a multi-touch surface (108) provided with a primary layer (112) and a secondary layer (114). The multi-touch surface (108) is configured for generating in response to the predefined geometrical pattern (106) being brought into contact with the primary layer (112) a corresponding pattern of electric interaction between the primary and secondary layers thereby enabling unique authentication based on said pattern of electric interaction.
