STAMP: Selective Task-Aware Mechanism for Text Privacy (2026.eacl-long)
Copied to clipboard
| Challenge: | Experimental evaluations on SQuAD, Yelp, and AG News datasets demonstrate that STAMP achieves superior privacy–utility trade-offs across varying per-token privacy budgets. |
| Approach: | They propose a new framework for task-aware text privatization that selectively allocates privacy budgets across tokens by jointly considering (i) each token’s importance to the downstream task and (ii) its privacy sensitivity. |
| Outcome: | The proposed framework achieves superior privacy–utility trade-offs on SQuAD, Yelp, and AG News datasets. |
