US Patent 9725171 Analyzing navigation data to detect navigation data spoofing

Techniques for determining whether data associated with an autonomous operation of an unmanned vehicle may be trusted. For example, the data may be analyzed in light of a capability of the unmanned vehicle. The analysis may indicate an operation of the unmanned vehicle. If the operation is unsupported by the capability, the data may be determined to be untrusted. Accordingly, the autonomous navigation may be directed independently of the untrusted data.
