Abstract

fetched live from OpenAlex

Today, data breaches pose a significant risk, especially those related to image data. Ideally, toward ultimate security, the image encryption should occur at the same time when the image is captured, directly within the sensor. Nonetheless, such optical sensors have not yet been achieved, limited by the physical properties of existing devices. Herein, we demonstrate a pioneer optical sensor that allows real-time, dual-physical-layer encryption directly within the sensor, enabled by the merits of III-nitride nanowires and careful engineering of the photocarrier dynamics within the nanowire heterojunctions. The robustness of the encryption is further tested against deep-learning-assisted cyber-attacks. Self-powered operation is also possible for such devices, representing a reduced energy cost for encryption. Moreover, the sensors are built directly on silicon (Si), making the technology compatible with existing Si electronics platforms. The simple epitaxy process of fabricating such sensors also means reduced time and production costs. This study represents a paradigm shift in image encryption research.

Not 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.
