EdgeCrypt Tracker: Object Tracking With Differential Encryption for IoAAV Surveillance
Bibliographic record
Abstract
This article proposes EdgeCrypt Tracker, an object-tracking algorithm combined with differential encryption to provide better accuracy and runtime efficiency for battery-operated Internet of Autonomous Aerial Vehicles (IoAAV). Specifically, EdgeCrypt Tracker operates directly on high-efficiency video coding (HEVC) and has three stages: 1) preprocessing; 2) object tracking; and 3) differential encryption. The preprocessing stage separates intra frames and removes artificial camera motion caused by camera movement from inter frames. Next, the object tracking stage utilizes a hybrid neural network, combining a single-shot multibox detector (SSD) network with a MobileNetV3 backbone that processes intra coded blocks and a fast gated recurrent neural network (FastGRNN) network that processes inter coded blocks. Finally, the tracked information is passed to the differential encryption stage, which encrypts all syntax elements within moving objects and alternate syntax elements related to the background. Experimental results demonstrate that EdgeCrypt Tracker achieves an average object tracking accuracy of 92%, real-time inference with a 35% lower encryption overhead compared to state-of-the-art methods. This work demonstrates the potential of integrating object tracking and encryption within video compression for secure, efficient AAV-based surveillance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
