Abstract

Claims (37)

1. A method for controlling access to a service by a user, the method being implemented by an access device to verify a human nature of the user and comprising:

generating a three-dimensional projection space comprising a virtual or mixed scene;

obtaining at least one three-dimensional virtual object and associated data, called solution data;

commanding a rendering of said at least one three-dimensional virtual object for the user by projecting said at least one three-dimensional virtual object onto said scene, in order to display said at least one three-dimensional virtual object in said scene;

obtaining interaction data on interaction of the user with said at least one three-dimensional virtual object; and

in response to the interaction data corresponding to the solution data, confirming the human nature of the user,

wherein the at least one three-dimensional virtual object comprises at least one polyhedron, at least one of its faces being hidden, and said solution data includes the user accessing the hidden face.

2. The access control method as claimed in claim 1 , wherein the interaction data comprise at least one selection datum for selecting said at least one three-dimensional virtual object.

3. The access control method as claimed in claim 1 , wherein the interaction data comprise at least one transformation datum for transforming said at least one three-dimensional virtual object.

4. A device for controlling access to a service by a user, comprising:

at least a non-transitory computer readable memory and a processor that are configured to:

generate a three-dimensional projection space comprising a virtual or mixed scene;

obtain at least one three-dimensional virtual object and associated data, called solution data, in order to display said at least one three-dimensional virtual object in said scene;

command a rendering of said at least one three-dimensional virtual object for the user by projecting said at least one three-dimensional virtual object onto said scene;

obtain interaction data on an interaction of the user with said at least one three-dimensional virtual object;

in response to the interaction data corresponding to the solution data, confirm a human nature of the user,

wherein the at least one three-dimensional virtual object comprises at least one polyhedron, at least one of its faces being hidden, and said solution data includes the user accessing the hidden face.

5. A system for controlling access to a service by a user, comprising at least

an access device comprising at least a non-transitory computer readable memory and a processor that are configured to:

generate a three-dimensional projection space comprising a virtual or mixed scene;

obtain at least one three-dimensional virtual object and associated data, called solution data, in order to display said at least one three-dimensional virtual object in said scene;

command a rendering of said at least one three-dimensional virtual object for the user on a rendering device by projecting said at least one three-dimensional virtual object onto said scene;

obtain interaction data on an interaction of the user with said at least one three-dimensional virtual object; and

in response to the interaction data corresponding to the solution data, confirm a human nature of the user,

wherein the at least one three-dimensional virtual object comprises at least one polyhedron, at least one of its faces being hidden, and said solution data includes the user accessing the hidden face;

the rendering device configured to render a virtual or mixed scene so as to render said at least one three-dimensional virtual object in said scene, said rendering comprising projecting said at least one three-dimensional virtual object in order to display it in said scene; and

a detection device configured to obtain the interaction data on the interaction of the user with said at least one three-dimensional virtual object in the scene.

6. The system for controlling access to a service as claimed in claim 5 , wherein the detection device comprises inertial sensors, eye-tracking sensors, motion-tracking sensors or cameras.

7. The system for controlling access to a service as claimed in claim 5 , wherein the rendering device is a virtual reality headset.

8. The system for controlling access to a service as claimed in claim 5 , wherein the detection device comprises a joystick.

9. A non-transitory computer readable medium comprising instructions stored thereon for implementing a method, which controls access to a service by a user to verify a human nature of the user, when the program is executed by a processor of an access device, wherein the method comprises:

generating a three-dimensional projection space comprising a virtual or mixed scene;

obtaining at least one three-dimensional virtual object and associated data, called solution data;

commanding a rendering of said at least one three-dimensional virtual object for the user by projecting said at least one three-dimensional virtual object onto said scene, in order to display said at least one three-dimensional virtual object in said scene;

obtaining interaction data on interaction of the user with said at least one three-dimensional virtual object; and

in response to the interaction data corresponding to the solution data, confirming the human nature of the user,

wherein the at least one three-dimensional virtual object comprises at least one polyhedron, at least one of its faces being hidden, and said solution data includes the user accessing the hidden face.
