Embodiment Construction

[0026] Touch screens are frequently used in smartphones or tablets. Most of these touchscreens are multi-touch enabled, as this allows various powerful user interaction principles (zooming, scrolling, rotation, etc.). In view of this, embodiments of the present invention propose to provide an object with a geometric pattern (eg as a tactile pattern), which can act as an identifier when held relative to a multi-touch screen. The multi-touch screen interprets the pattern and converts it into an identifier representing a user, a specific user type (eg, a "role" such as patient, nurse), or a specific piece of content.

[0027] Figure 1A A system 102 for authentication is shown schematically, comprising an authentication object 104 provided with a predefined geometric pattern 106 for authentication. System 102 also includes multi-touch surface 108 . refer to Figure 1B, the multi-touch surface 108 is provided with a primary layer 112 and a secondary layer 114 . The multi-touch...

Abstract

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.

Description

technical field [0001] The invention relates to a system for authentication. Background technique [0002] US 2009 / 0085877 A1 discloses a system for user authentication using a multi-touch screen. The system authenticates a user based on multiple points of contact of the user's hand with the multi-touch screen, since each hand has a unique contact pattern. In practice, however, a user cannot accurately reproduce a unique contact pattern that provides his or her authentication. Thus, the system is to employ relatively low standards with respect to the accuracy with which the unique contact pattern needs to be regenerated by the user; the system is to allow the user to regenerate its unique contact pattern with relatively large deviations . Thus, for users with similar unique contact patterns, given the allowance for large deviations in regenerating the user's unique contact patterns, false authentication may occur. As a result, the problem with this system is its limited ...
