Presenting sonic signals to prevent digital content misuse

1. A method comprising:

receiving, by a client-side computing device, a digital movie from a remote computing system, a user authorized with the client-side computing device having purchased a limited license to access the digital movie;

presenting, on a display, a visible code that, when detected by an optical sensor of the mobile computing device, causes the mobile computing device to initiate a sonic signal detection mode during which a microphone of the mobile computing device actively listens for sonic signals presented by the client-side computing device;

periodically presenting, by the client-side computing device, sonic signals during presentation of the digital movie received from the remote computing system, the sonic signals being presented to confirm that the mobile computing device of the user authorized with the client-side computing device is within a desired geographic distance of the client-side computing device while the client-side computing device is presenting the digital movie received from the remote computing system, wherein each sonic signal is embedded in the digital movie, and each sonic signal, upon being detected by the mobile computing device, causes the mobile computing device to transmit a confirmation message to the remote computing system confirming that the mobile computing device detected the sonic signal;

receiving, by the client-side computing device during the presentation of the digital movie, a notification that a number of unconfirmed sonic signals exceeds a threshold number of allowable unconfirmed sonic signals, wherein the number of unconfirmed sonic signals indicates a number of sonic signals presented by the client-side computing device that the mobile computing device did not confirm detecting; and

in response to receiving the notification that the number of unconfirmed sonic signals exceeds the threshold number of allowable unconfirmed sonic signals, suspending the presentation of the digital movie.

2. The method of claim 1 , wherein the visible code, upon being detected by the mobile computing device, further causes the mobile computing device to transmit an identifier associated with the mobile computing device and an identifier associated with the client-side computing device to the remote server.

3. The method of claim 1 , wherein the visible code is a quick response (QR) code that can be detected by an optical sensor of the mobile computing device.

4. The method of claim 1 , wherein each sonic signal is embedded with a code and the mobile computing device includes the code embedded in the confirmation message to the remote computing system.

5. The method of claim 4 , wherein periodically presenting sonic signals comprises:

presenting a first sonic signal embedded with a first code; and

presenting a second sonic signal embedded with a second code, wherein the second code is different than the first code.

6. The method of claim 4 , wherein the code includes an identifier for the client-side computing device.

7. The method of claim 1 , further comprising:

terminating the presentation of the digital movie; and

disabling the client-side computing device.

8. The method of claim 1 , further comprising:

receiving a command from the remote server to resume performance of the digital movie; and

in response to receiving the command, resuming performance of the digital movie.

9. A client-side computing device comprising:

one or more computer processors; and

one or more computer-readable mediums storing instructions that, when executed by the one or more computer processors, cause the client-side computing device to perform operations comprising:

receiving a digital movie from a remote computing system, a user authorized with the client-side computing device having purchased a limited license to access the digital movie;

presenting, on a display, a visible code that, when detected by an optical sensor of the mobile computing device, causes the mobile computing device to initiate a sonic signal detection mode during which a microphone of the mobile computing device actively listens for sonic signals presented by the client-side computing device;

periodically presenting sonic signals during presentation of the digital movie received from the remote computing system, the sonic signals being presented to confirm that the mobile computing device of the user authorized with the client-side computing device is within a desired geographic distance of the client-side computing device while the client-side computing device is presenting the digital movie received from the remote computing system, wherein each sonic signal is embedded in the digital movie, and each sonic signal, upon being detected by the mobile computing device, causes the mobile computing device to transmit a confirmation message to the remote computing system confirming that the mobile computing device detected the sonic signal;

receiving, during the presentation of the digital movie, a notification that a number of unconfirmed sonic signals exceeds a threshold number of allowable unconfirmed sonic signals, wherein the number of unconfirmed sonic signals indicates a number of sonic signals presented by the client-side computing device that the mobile computing device did not confirm detecting; and

in response to receiving the notification that the number of unconfirmed sonic signals exceeds the threshold number of allowable unconfirmed sonic signals, suspending the presentation of the digital movie.

10. The client-side computing device of claim 9 , wherein the visible code, upon being detected by the mobile computing device, further causes the mobile computing device to transmit an identifier associated with the mobile computing device and an identifier associated with the client-side computing device to the remote server.

11. The client-side computing device of claim 10 , wherein the visible code is a quick response (QR) code that can be detected by an optical sensor of the mobile computing device.

12. The client-side computing device of claim 9 , wherein each sonic signal is embedded with a code and the mobile computing device includes the code embedded in the confirmation message to the remote computing system.

13. The client-side computing device of claim 12 , wherein periodically presenting sonic signals comprises:

presenting a first sonic signal embedded with a first code; and

presenting a second sonic signal embedded with a second code, wherein the second code is different than the first code.

14. The client-side computing device of claim 12 , wherein the code includes an identifier for the client-side computing device.

15. The client-side computing device of claim 9 , the operations further comprising:

terminating the presentation of the digital movie; and

disabling the client-side computing device.

16. A non-transitory computer-readable medium storing instructions that, when executed by one or more computer processors of a client-side computing device, cause the client-side computing device to perform operations comprising:

receiving a digital movie from a remote computing system, a user authorized with the client-side computing device having purchased a limited license to access the digital movie;

presenting, on a display, a visible code that, when detected by an optical sensor of the mobile computing device, causes the mobile computing device to initiate a sonic signal detection mode during which a microphone of the mobile computing device actively listens for sonic signals presented by the client-side computing device;
