Abstract

fetched live from OpenAlex

In this work, we design a balanced access control system,where a robust system becomes flexible to meet its users'needs. On one hand, the system administrator sets system wide policies that all users must comply with. Policies are integrated into private keys of users, setting an access structure over attributes (resources) they can access. On the other hand, users are able to set their own access structure over system policies for documents they generate in the system. Users are in control of who and under what conditions can access their documents. This way, a system administrator can help users set their own access control policies while both users' privacy and system's security are preserved. Our system is based on two attribute-based encryption schemes: KP-ABE and CP-ABE. The former puts access policies into decryption keys, and the latter combines access policies with ciphertexts. In our work, we show how these two separate systems can be efficiently combined into a flexible, yet robust access control system.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
