Abstract

Aspects of the present invention provide an approach for authentication of a user of a computer system by displaying holographic objects in a bounded field of view of a user, identifying movement of the user interacting with the holographic objects, comparing the interacting movement to authentication information linking user authentication to a movement defined within confidence limits, and when the identified user movement indicates the user interacted with the displayed holographic objects within the defined confidence limits, authenticating the user on the computer system.

Claims

1. A method for authenticating a user of a computer system, wherein the computer system comprises at least one holographic image display device and at least one user monitoring device, the method comprising:

displaying, in response to a request for access by a user and via the at least one holographic image display device, one or more holographic objects in a field of view of at least one user;

identifying via data received from said at least one user monitoring device, movement of the at least one user interacting with the displayed one or more holographic objects;

comparing the identified user movement to a predefined set of authentication information for the at least one user that links user authentication to a movement defined within confidence limits of the at least one user interacting with the displayed one or more holographic objects; and

when the identified user movement indicates the at least one user interacted with the displayed one or more objects within the defined confidence limits, then authenticating the user.

2. The method of claim 1, wherein said predefined set of authentication information varies between each previous and subsequent authentication.

3. The method of claim 1, wherein said predefined set of authentication information varies between each previous and subsequent authentication based on user entry at setup of a plurality of defined movements, each of the defined movements corresponding to one in a series of authentications anticipated to follow setup.

4. The method of claim 3, wherein the user is provided a reminder image pattern comprising a reminder of the required predefined set of authentication information for a given authentication.

5. The method of claim 4, wherein a cognitive computer system varies said predefined authentication information for each authentication based on a database of possible defined movements provided by the user at setup or a database of personal history of defined movements of the user or both and provides a reminder image therefore.

6. The method of claim 1, wherein said defined movement is characterized by parameters selected from a group, consisting of:

position of object, size of object, color of object, pattern of object, speed of movement, direction of movement, precision of movement, precision of location of object or movement or both, precision of speed, and position of user grip on an object.

7. The method of claim 1, wherein said defined movement comprises a preamble pattern comprising at least a portion of the defined movement required for the previous authentication, a core authentication pattern, and an ending pattern comprising noise.

8. A computer system for authenticating a user, comprising:

a holographic image display device;

a user monitoring device;

a memory medium comprising instructions;

a bus coupled to the memory medium; and

a processor coupled to the bus that when executing the instructions causes the system to perform a method, comprising;

displaying, in response to a request for access by a user and via the at least one holographic image display device, one or more objects in a field of view of at least one user;

identifying via data received from said at least one user monitoring device movement of the at least one user interacting with the displayed one or more holographic objects;

comparing the identified user movement to a predefined set of authentication information for the at least one user that links user authentication to a movement defined within confidence limits of the at least one user interacting with the displayed one or more holographic objects; and

when the identified user movement indicates the at least one user interacted with the displayed one or more holographic objects within the defined confidence limits, then authenticating the user.

9. The computer system of claim 8, wherein said predefined set of authentication information varies between each previous and subsequent authentication.

10. The computer system of claim 8, wherein said predefined set of authentication information varies between each previous and subsequent authentication based on user entry at setup of a plurality of defined movements, each of the defined movements corresponding to one in a series of authentications anticipated to follow setup.

11. The computer system of claim 10, wherein the user is provided a reminder image pattern comprising a reminder of the required predefined set of authentication information for a given authentication.

12. The computer system of claim 11, wherein a cognitive computer system varies said predefined authentication information for each authentication based on a database of possible defined movements provided by the user at setup or a database of personal history of defined movements of the user or both and provides a reminder image therefore.

13. The computer system of claim 8, wherein said defined movement is characterized by parameters selected from a group, consisting of:

position of object, size of object, color of object, pattern of object, speed of movement, direction of movement, precision of movement, precision of location of object or movement or both, precision of speed, and position of user grip on an object.

14. The computer system of claim 8, wherein said defined movement comprises a preamble pattern comprising at least a portion of the defined movement required for the previous authentication, a core authentication pattern, and an ending pattern comprising noise.

15. A computer program product embodied in a computer readable medium that, when executed by a computer device, performs a method for authenticating a user of a computer system comprising at least one image display device and at least one user monitoring device, the method comprising:

displaying, in response to a request for access by a user and via the at least one image display device, one or more objects in a field of view of at least one user;

identifying via data received from said at least one user monitoring device movement of the at least one user interacting with the displayed one or more objects;

comparing the identified user movement to a predefined set of authentication information for the at least one user that links user authentication to a movement defined within confidence limits of the at least one user interacting with the displayed one or more holographic objects; and

when the identified user movement indicates the at least one user interacted with the displayed one or more objects within the defined confidence limits, then authenticating the user.

16. The computer program product of claim 15, wherein said predefined set of authentication information varies between each previous and subsequent authentication.

17. The computer program product of claim 15, wherein said predefined set of authentication information varies between each previous and subsequent authentication based on user entry at setup of a plurality of defined movements, each of the defined movements corresponding to one in a series of authentications anticipated to follow setup.

18. The computer program product of claim 17, wherein the user is provided a reminder image pattern comprising a reminder of the required predefined set of authentication information for a given authentication.

19. The computer program product of claim 18, wherein a cognitive computer system varies said predefined authentication information for each authentication based on a database of possible defined movements provided by the user at setup or a database of personal history of defined movements of the user or both and provides a reminder image therefore.

20. The computer program product of claim 15, wherein said defined movement is characterized by parameters selected from a group consisting of:

position of object, size of object, color of object, pattern of object, speed of movement, direction of movement, precision of movement, precision of location of object or movement or both, precision of speed, and position of user grip on an object.
