Abstract

fetched live from OpenAlex

Context-aware computing facilitates the human-computer interaction by sensing and processing information about users and their environments. The surrounding environment becomes a smart space that actively communicates with the system about its users. In this environment, authentication is an integral part of security of the whole system. In this work, we propose a framework to construct a context-aware authentication system, where users customize their preferences and set their rules for authenticating other members. The context-aware authentication service uses context-data to establish trust and to share secrets between parties without undermining each party's privacy. Users' preferences are intuitively declared via lexical descriptions and are then combined with fuzzy logics. The framework utilizes an approximate private matching protocol which is combined with Identity Based Encryption. Our model is based upon reliable cryptographic primitives that are combined effectively to achieve the design specification. This results in a very flexible, scalable authentication service that is both context-aware and privacy preserving. (8 pages)

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.
