Interactive secret sharing |
| 摘要 |
Interactive secret sharing includes receiving video data from a source and interpreting the video data to track an observed path of a device. In addition, position information is received from the device, and the position information is interpreted to track a self-reported path of the device. If the observed path is within a threshold tolerance of the self-reported path, access is provided to a restricted resource. |

1. A data-holding subsystem holding instructions executable by a logic subsystem to:
receive video data from a source; interpret the video data to track an observed path of a device; receive position information from the device; interpret the position information to track a self-reported path of the device; and if the observed path is within a threshold tolerance of the self-reported path, provide access to a restricted resource. |
