Abstract

A system is provided for controling access to a resource, the access being restricted by an access mechanism. The system comprises an access control subsystem for i) subjecting the user to one or more security measures based on use of a security input system, and ii) signaling the access mechanism to grant the user access to the resource based on the user passing the one or more security measures. The system further comprises a task interlace for accessing task data, the task data being indicative of a scheduled task of the user. The access control subsystem is further arranged for determining the one or more security measures based on the scheduled task to establish different levels of security depending on the task. Advantageously, a better adjusting of the level of security is obtained in that it is dynamically adjusted to the scheduled task of the user.

First claim

The invention claimed is:

1. A system for controlling access to a resource by signaling an access mechanism which restricts access to the resource, the system comprising:
an identification subsystem for receiving identification data, the identification data being indicative of a user;
an access control subsystem for i) subjecting the user to one or more security measures based on use of a security input system, and ii) signaling the access mechanism to grant the user access to the resource based on the user passing the one or more security measures; and
a task interface for accessing task data, the task data being indicative of a scheduled task of the user;
wherein the access control subsystem is arranged for determining the one or more security measures based on the scheduled task to establish different levels of security depending on the scheduled task.

2. The system according to claim 1 , wherein the access control subsystem is arranged for i) estimating a relevance of the resource to the scheduled task based on the task data, and ii) determining the one or more security measures based on said relevance.

3. The system according to claim 1 , wherein the task data comprises an agenda of the user, and wherein the access control subsystem is arranged for i) estimating an occurrence frequency of the scheduled task based on the agenda, and ii) determining the one or more security measures based on the occurrence frequency.

4. The system according to claim 1 , wherein the task interface is arranged for accessing user data indicative of a role of the user, and wherein the access control subsystem is arranged for determining the one or more security measures based on further input provided by the role of the user.

5. The system according to claim 1 , further comprising a location determining subsystem for determining a location of the user and/or the resource, and wherein the access control subsystem is arranged for determining the one or more security measures based on further input provided by said location.

6. The system according to claim 4 , wherein the access control subsystem is arranged for estimating a consistency between the scheduled task and the further input, and ii) determining the one or more security measures based on said consistency.

7. The system according to claim 1 , wherein the task interface is arranged for receiving a notification being indicative of an interrupting task having a higher priority than the scheduled task of the user, and wherein the access control subsystem is arranged for determining the one or more security measures based on the interrupting task instead of the scheduled task.

8. The system according to claim 7 , wherein the notification is indicative of a further user associated with the interrupting task, and wherein the access control subsystem is arranged for determining the one or more security measures further based on a role and/or a location of the further user.

9. The system according to claim 7 , wherein the interrupting task is an emergency task.

10. The system according to claim 1 , wherein the resource is a medical resource.

11. The system according to claim 10 , wherein the medical resource is constituted by at least one of: patient information, medication, and medical equipment.

12. A workstation or imaging apparatus comprising the system of claim 1 .

13. A mobile device comprising the system of claim 1 .

14. A method of controlling access to a resource by signaling an access mechanism which restricts access to the resource, the method comprising:
receiving identification data, the identification data being indicative of a user;
subjecting the user to one or more security measures based on use of a security input system;
signaling the access mechanism to grant the user access to the resource based on the user passing the one or more security measures;
accessing task data, the task data being indicative of a scheduled task of the user; and
determining the one or more security measures based on the scheduled task to establish different levels of security depending on the scheduled task.

15. A computer program product comprising instructions for causing a processor system to perform the method according to claim 14 .
