Computer challenge system for presenting images to users corresponding to correct or incorrect real-world properties to limit access of computer resources to intended human users
A method of securing a computer resource against unauthorized access by authenticating user devices attempting to access the computer resource comprises determining a three-dimensional (3D) model of a virtual scene, wherein elements of the virtual scene are selected consistent with human expectations, generating a data record for the 3D model, wherein the data record includes references to pre-determined set of human expectations about the virtual scene, generating a two-dimensional (2D) image of the virtual scene, sending a challenge data structure to a user device, wherein the challenge data structure includes the 2D image, obtaining a user response representing a user-provided set of expectations about the virtual scene, determining whether the user-provided set of expectations is consistent with the pre-determined set of human expectations, and providing access to the computer resource for the user device based on whether the set of expectations is consistent with the pre-determined set of human expectations.
1. A method of securing a computer resource against unauthorized access by authenticating a user device attempting to access the computer resource, the method comprising:
determining a three-dimensional (3D) model of a virtual scene, wherein elements of the virtual scene are selected consistent with human expectations;
generating a data record for the 3D model, wherein the data record includes references to a pre-determined set of human expectations about the virtual scene;
generating a two-dimensional (2D) image of the virtual scene by a challenge generator,
wherein the 2D image comprises a view of dice from a virtual camera position, and
wherein the dice are oriented such that a sum of values represented on top faces of the dice equals to an input parameter selected by the challenge generator;
sending a challenge data structure to the user device, wherein the challenge data structure includes the 2D image;
obtaining a user response representing a user-provided set of expectations about the virtual scene;
determining whether the user-provided set of expectations is consistent with the pre-determined set of human expectations; and
providing access to the computer resource for the user device based on whether the user-provided set of expectations is consistent with the pre-determined set of human expectations and the user response is equal to the input parameter selected by the challenge generator.
2. The method of claim 1 , wherein the pre-determined set of human expectations correspond to placement of elements in the virtual scene that are placed consistent with commonly-held real-world human experiences with respect to the elements.
3. The method of claim 1 , wherein providing access to the computer resource for the user device comprises indicating to another computer system whether to provide that access.
4. The method of claim 1 , wherein the 2D image of the virtual scene is one of a plurality of image tiles provided as part of a presentation to the user device.
5. The method of claim 1 , wherein the values represented on the top faces of at least some of the dice are represented as numbers.
6. The method of claim 1 , wherein the values represented on the top faces of at least some of the dice are represented as pips.
7. A system for securing a computer resource against unauthorized access by authenticating a user device attempting to access the computer resource, the system comprising:
a memory; and
a processing device, operatively coupled to the memory, to:
determine a three-dimensional (3D) model of a virtual scene, wherein elements of the virtual scene are selected consistent with human expectations;
generate a data record for the 3D model, wherein the data record includes references to a pre-determined set of human expectations about the virtual scene;
generate a two-dimensional (2D) image of the virtual scene by a challenge generator,
wherein the 2D image comprises a view of dice from a virtual camera position, and
wherein the dice are oriented such that a sum of values represented on top faces of the dice equals to an input parameter selected by the challenge generator;
send a challenge data structure to the user device, wherein the challenge data structure includes the 2D image;
obtain a user response representing a user-provided set of expectations about the virtual scene;
determine whether the user-provided set of expectations is consistent with the pre-determined set of human expectations; and
provide access to the computer resource for the user device based on whether the user-provided set of expectations is consistent with the pre-determined set of human expectations and the user response is equal to the input parameter selected by the challenge generator.
8. The system of claim 7 , wherein, to provide access to the computer resource for the user device, the processing device is to indicate to another computer system whether to provide that access.
9. The system of claim 7 , wherein the 2D image of the virtual scene is one of a plurality of image tiles provided as part of a presentation to the user device.
10. The system of claim 7 , wherein the values represented on the top faces of at least some of the dice are represented as numbers.
11. The system of claim 7 , wherein the values represented on the top faces of at least some of the dice are represented as pips.
12. A non-transitory computer-readable storage medium for securing a computer resource against unauthorized access by authenticating a user device attempting to access the computer resource, the non-transitory computer-readable storage medium including instructions that, when executed by a processing device, cause the processing device to:
determine a three-dimensional (3D) model of a virtual scene, wherein elements of the virtual scene are selected consistent with human expectations;
generate a data record for the 3D model, wherein the data record includes references to a pre-determined set of human expectations about the virtual scene;
generate a two-dimensional (2D) image of the virtual scene by a challenge generator,
wherein the 2D image comprises a view of dice from a virtual camera position, and
wherein the dice are oriented such that a sum of values represented on top faces of the dice equals to an input parameter selected by the challenge generator;
send a challenge data structure to the user device, wherein the challenge data structure includes the 2D image;
obtain a user response representing a user-provided set of expectations about the virtual scene;
determine whether the user-provided set of expectations is consistent with the pre-determined set of human expectations; and
provide access to the computer resource for the user device based on whether the user-provided set of expectations is consistent with the pre-determined set of human expectations and the user response is equal to the input parameter selected by the challenge generator.
13. The non-transitory computer-readable storage medium of claim 12 , wherein, to provide access to the computer resource for the user device, the processing device is to indicate to another computer system whether to provide that access.
14. The non-transitory computer-readable storage medium of claim 12 , wherein the 2D image of the virtual scene is one of a plurality of image tiles provided as part of a presentation to the user device.
15. The non-transitory computer-readable storage medium of claim 12 , wherein the values represented on the top faces of at least some of the dice are represented as numbers.
16. The non-transitory computer-readable storage medium of claim 12 ,
wherein the values represented on the top faces of at least some of the dice are represented as pips.
