Abstract

fetched live from OpenAlex

The opportunity to access on-demand, unbounded computation and storage resources has increasingly motivated users to move their health records from local data centers to the cloud environment. This change can reduce the costs associated with the management of data sharing, communication overhead and improve Quality of Service (QoS). Processing, storing, hosting and archiving data related to e-Health systems without physical access and control can exacerbate authentication and access control issues in this new environment. Therefore, convincing users to move sensitive medical records to the cloud environment requires implementing secure and strong authentication and access control methods to protect the data. This paper proposes a new information access method that preserves both authentication and access control in cloud-based e-Health systems. Our method is based on a zero-knowledge protocol combined with two-stage keyed access control. In each access request, based on the maximum rights of user, the minimum access is extracted. To establish secure connections between different entities in the system, a two-step combination of public key encryption and DUKPT is used. We analyze our scheme with respect to data confidentiality and resistance to common attacks on the network. Experimental results show that the proposed method tolerates a high number of concurrent authentication requests with a reasonable response time.

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.
