Abstract

A video stream from a user device that is destined for a recipient device is received at a core network of a wireless carrier network. The video stream has a video quality that at least meets a quality threshold for behavioral biometric analysis. A determination of whether a video privacy policy for the user device permits transmission of the video stream of the video quality to the recipient device is made. In response to the video privacy policy not permitting the transmission of the video stream of the video quality, the video quality of the video stream is downgraded to generate a downgraded video stream that prevents behavioral biometric analysis for transmission to the recipient device. However, in response to the video privacy policy permitting the transmission of the video stream of the video quality, the video stream of the video quality is transmitted to the recipient device.

First claim

What is claimed is:

1. One or more non-transitory computer-readable media of a core network of a wireless carrier network storing computer-executable instructions that upon execution cause one or more computing nodes to perform acts comprising:
receiving a video stream from a user device that is destined for a recipient device at the core network of the wireless carrier network, the video stream having a video quality that at least meets a quality threshold for behavioral biometric analysis;
determining whether a video privacy policy for the user device permits transmission of the video stream of the video quality to the recipient device;
in response at least to the video privacy policy not permitting the transmission of the video stream of the video quality, downgrading the video quality of the video stream to generate a downgraded video stream that prevents behavioral biometric analysis and transmitting the downgraded video stream to the recipient device; and
in response to the video privacy policy permitting the transmission of the video stream of the video quality, transmitting the video stream of the video quality to the recipient device.

2. The one or more non-transitory computer-readable media of claim 1 , wherein the acts further comprise determining that the video quality of the video stream at least meets the quality threshold when a video resolution of the video stream at least meets a video resolution threshold.

3. The one or more non-transitory computer-readable media of claim 1 , wherein the acts further comprise determining that the video quality of the video stream at least meets the quality threshold at least when a video resolution of the video stream at least meets a video resolution threshold component and a video bitrate of the video stream at least meets a video bitrate threshold component.

4. The one or more non-transitory computer-readable media of claim 1 , wherein the acts further comprise determining that the video quality of the video stream at least meets the quality threshold when a predetermined number of behavioral biometric characteristics of a person are detected in video content of the video stream by a behavioral biometric analysis algorithm.

5. The one or more non-transitory computer-readable media of claim 4 , wherein the behavioral biometric analysis algorithm is executed by an artificial intelligence (AI) chipset of the user device.

6. The one or more non-transitory computer-readable media of claim 1 , wherein the downgrading the video quality includes at least one of applying a scramble mask to the video stream to scramble video content of the video stream or re-encoding the video stream into a lower quality video stream that has at least one of a lower video resolution or a lower bitrate that prevents the behavioral biometric analysis.

7. The one or more non-transitory computer-readable media of claim 6 , wherein the applying the scrambling mask or the re-encoding includes applying the scrambling mask to the video stream or re-encoding the video stream at an edge server associated with a base station of the wireless carrier network.

8. The one or more non-transitory computer-readable media of claim 1 , wherein the downgrading the video quality includes directing the user device to encode the video stream as captured by a camera of the user device using at least one of a lower video resolution or a lower video bitrate setting.

9. The one or more non-transitory computer-readable media of claim 1 , further comprising, in response to the video privacy policy not permitting the transmission of the video stream of the video quality, directing the user device to present a warning notification indicating that the video stream is usable for the behavioral biometric analysis, and requesting an input as whether to downgrade the video quality of the video stream.

10. The one or more non-transitory computer-readable media of claim 9 , wherein the downgrading includes downgrading the video quality of the video stream in response to receiving a selection from the user device to downgrade the video quality.

11. A user device, comprising:
one or more processors; and
memory including a plurality of computer-executable components that are executable by the one or more processors to perform a plurality of actions, the plurality of actions comprising:
receiving a video stream that includes image signals from a camera of the user device, the video stream having a video quality that at least meets a quality threshold for behavioral biometric analysis;
determining whether a video privacy policy for the user device permits capture and storage of the video stream of the video quality at the user device;
in response at least to the video privacy policy not permitting the capture and storage of the video stream of the video quality at the user device, downgrading the video quality of the video stream to generate a downgraded video stream that prevents behavioral biometric analysis and storing the downgraded video stream in a data store of the user device; and
in response to the video privacy policy permitting the capture and storage of the video stream of the video quality, storing the video stream of the video quality in the data store of the user device.

12. The user device of claim 11 , wherein the plurality of actions further comprise determining that the video quality of the video stream at least meets the quality threshold when a video resolution of the video stream at least meets a video resolution threshold.

13. The user device of claim 11 , wherein the plurality of actions further comprise determining that the video quality of the video stream at least meets the quality threshold at least when a video resolution of the video stream at least meets a video resolution threshold component and a video bitrate of the video stream at least meets a video bitrate threshold component.

14. The user device of claim 11 , wherein the plurality of actions further comprise determining that the video quality of the video stream at least meets the quality threshold when a predetermined number of behavioral biometric characteristics of a person are detected in video content of the video stream by a behavioral biometric analysis algorithm.

15. The user device of claim 14 , wherein the behavioral biometric analysis algorithm is executed by an artificial intelligence (AI) chipset of the user device.

16. The user device of claim 11 , wherein the video quality downgrading includes at least one of applying a scramble mask to the video stream to scramble video content of the video stream, re-encoding the video stream into a lower quality video stream that has at least one of a lower video resolution or a lower bitrate that prevents the behavioral biometric analysis, or encoding new image signals for the video stream into the lower quality video stream.

17. The user device of claim 11 , further comprising, in response to the video privacy policy not permitting the capture and storage of the video stream of the video quality, directing the user device to present a warning notification indicating that the video stream is usable for the behavioral biometric analysis, and requesting an input as whether to downgrade the video quality of the video stream.

18. The user device of claim 17 , wherein the downgrading includes downgrading the video quality of the video stream in response to receiving a selection from the user device to downgrade the video quality.

19. A computer-implemented method, comprising:
receiving, at one or more computing nodes, a vid
