Entwining Sanitization and Personalization on Databases
Bibliographic record
Abstract
In the last decade, a lot of research has been done to prevent the illegal distribution of digital content, % in the context in which the proprietary content is a medium such as musical works and movies. However, only few works have tackled this problem for databases, and even less for databases containing personal and sensitive information (\emphe.g, a medical database). In this work, we address this latter issue by proposing øuralgo\ (for Sanitization and Personalization of Databases ), an approach in which the owner of a database personalizes it before distributing it to ensure that a malicious buyer can be traced back in case of an illegal redistribution. Our novel solution entwines the personalization step with a sanitization mechanism to prevent the leak of personal information and limit the privacy risks. Thus, our objective is to release a sanitized and personalized database, both to protect the privacy of the concerned individuals and to prevent the illegal redistribution, even from a collusion of malicious buyers.

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.
