Abstract

Systems and methods described herein utilize a distributed server network to allow for the real-time distribution of copies of a data stream uploaded from a computing device. The uploaded data stream corresponds to an environment surrounding a user (exam taker) of the computing device during execution of a testing routine for an examination. Providing copies of the data stream in real-time allows proctors as well as other test assessment authorities to ‘peek in’ on the exam taker'"'"'s environment during the exam. As a result, the environment surrounding the exam taker can be monitored in real-time to determine whether any visual or audio activity in the environment constitutes activity not in accordance with the exam protocol. Following an affirmative determination that the exam taker violated an exam taking protocol, a proctor or other test assessment authority can then make a final or early decision regarding disciplinary action.

Claims

1. A method for managing distribution of a data stream from a distributed server network, the method comprising:

receiving a data stream from over a first network and into a second network, the second network including a distributed server network, the data stream corresponding to an environment surrounding a user of a first computing device during execution of a testing routine for an examination;

storing the received data stream data at the distributed server network;

receiving a request to transmit the data stream to a second computing device, the request including meta-data and received over the distributed server network during execution of the testing routine; and

identifying one or more servers of the distributed server network to process the request based on the meta-data;

selecting a server of the one or more identified servers to process the request by transmitting the data stream to the second computing device, the server selected based on one or more estimated performance metrics for a network path from the selected server to the second computing device of the one or more servers;

transmitting the data stream from the selected server in the distributed server network to the second computing device in response to the request, the data stream transmitted during execution of the testing routine; and

receiving a second request to transmit the data stream to a third computing device, the second request received during execution of the testing routine; and

transmitting the data stream from a second server in the distributed server network to the third computing device during execution of the testing routine in response to the second request.

2. The method of claim 1, wherein the second request is received from the second computing device.

3. The method of claim 1, wherein the data stream is a video data stream of the environment surrounding the user of the first computing device during the testing routine, and transmitting the data stream to the second computing device includes transmitting the video data stream for display on the second computing device during the testing routine.

4. The method of claim 1, further comprising:

receiving an indication from the second computing device than aberrant behavior in the environment has been detected through analysis of the data stream; and

intervening in the testing routine to resolve the aberrant behavior.

5. The method of claim 4, wherein intervening in the testing routine comprises transmitting a request to the first computing device that the environment be modified to resolve the aberrant behavior.

6. The method of claim 4, wherein intervening in the testing routine comprises transmitting a request to the first computing device that the testing routine for the examination is no longer allowed to continue.

7. The method of claim 1, further comprising:

receiving an indication from the second computing device than aberrant behavior in the environment has been detected through analysis of the data stream;

providing an indication that the testing routine for the examination on the first computing device is allowed to continue subject to further analysis of the data stream during grading of the examination.

8. A computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for managing distribution of a data stream from a distributed server network, the method comprising:

receiving a data stream from over a first network and into a second network, the second network including a distributed server network, the data stream corresponding to an environment surrounding a user of a first computing device during execution of a testing routine for an examination;

storing the received data stream data at the distributed server network;

receiving a request to transmit the data stream to a second computing device, the request including meta-data and received over the distributed server network during execution of the testing routine;

identifying one or more servers of the distributed server network to process the request based on the meta-data;

selecting a server of the one or more identified servers to process the request by transmitting the data stream to the second computing device, the server selected based on one or more estimated performance metrics for a network path from the selected server to the second computing device of the one or more servers;

transmitting the data stream from the selected server in the distributed server network to the second computing device in response to the request, the data stream transmitted during execution of the testing routine; and

receiving a second request to transmit the data stream to a third computing device, the second request received during execution of the testing routine; and

transmitting the data stream from a second server in the distributed server network to the third computing device during execution of the testing routine in response to the second request.

9. The computer readable storage medium of claim 8, wherein the second request is received from the second computing device.

10. The computer readable storage medium of claim 8, wherein the data stream is a video data stream of the environment surrounding the user of the first computing device during the testing routine, and transmitting the data stream to the second computing device includes transmitting the video data stream for display on the second computing device during the testing routine.

11. The computer readable storage medium of claim 8, wherein the method further comprises:

receiving an indication from the second computing device than aberrant behavior in the environment has been detected through analysis of the data stream; and

intervening in the testing routine to resolve the aberrant behavior.

12. The computer readable storage medium of claim 11, wherein intervening in the testing routine comprises transmitting a request to the first computing device that the environment be modified to resolve the aberrant behavior.

13. The computer readable storage medium of claim 11, wherein intervening in the testing routine comprises transmitting a request to the first computing device that the testing routine for the examination is no longer allowed to continue.

14. The computer readable storage medium of claim 8, wherein the method further comprises:

receiving an indication from the second computing device than aberrant behavior in the environment has been detected through analysis of the data stream;

providing an indication that the testing routine for the examination on the first computing device is allowed to continue subject to further analysis of the data stream during grading of the examination.
