TRACING THE DOP, THE DISTINCT OPERATING PATTERN, IN ORDER TO FIND THE FIST:

Hackers, telegraph operators and UAV users all have one important thing in common; a DOP (Distinct Operating Pattern). The latest DOP to be discovered and applied in a practical way uses an app that tracks the movement of a UAV and within a short period (way before the quadcopter battery runs low and forces it to land) deduces the location of the operator. The AI (artificial intelligence) drone-tracking algorithm needs a 3-D map of the area where UAVs will be tracked. The AI is a GRU (Gated-Recurrent Unit) neural network that studies movements in space and time and is able to track the movements of the quadcopter back to its origin (launch point) with over 80 percent accuracy. That accuracy improves the more the algorithm is used, and modifies itself…

Historical sketch:

The technique was discovered in the mid-1800s by accident. In the early days of the telegraph experienced operators found that they could tell who was on the other end of a telegraph line by the rhythm of how the telegraph key was hit. This was called the operators “fist.” When computers came along it was possible to automate that particular intelligence gathering task. For example, each user has a distinct typing pattern and rhythm that produces an identifiable “fist.”

All is not lost. “It is possible to deceive all these DOP methods. Hackers can automate phony “fists” and similar deceptions.” It’s StrategyPage’s latest Murphy’s Law update, and well worth the read.
