Harm Mitigation from the Release of Personal Identity Information
Bibliographic record
Abstract
In August 2007 approximately 445,000 letters were sent to retirees who belonged to the California Public Employees’ Retirement System (CalPERS). This was a routine mailing, but all or a portion of each pensioner’s Social Security Number (SSN) was printed on the address panel of the envelopes, making this event all but ordinary. This massive breach of sensitive SSNs, along with names and addresses, exposed these people to potential identity theft and fraud. What are the harms associated with a data breach of this nature? How can those harms be mitigated? What are, or should be, the costs and consequences to the organization releasing the data? While it is very difficult to predict the specific consequences of a data breach of this nature, a statistical model can be used to estimate the likely financial repercussions for individuals and organizations, and the recent settlement in the TJX case provides a good model of harm mitigation that could be applied in this case and similar cases.

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.
