Privacy-Preserving Natural Language Processing (2023.eacl-tutorials)
Copied to clipboard
| Challenge: | This tutorial will help the NLP community to get familiar with current research in privacy-preserving methods. |
| Approach: | This tutorial will help the NLP community to get familiar with current research in privacy-preserving methods. |
| Outcome: | The tutorial will cover membership inference, differential privacy, homomorphic encryption, or federated learning, all with typical use-cases and potential pitfalls. |
A Hassle-free Algorithm for Strong Differential Privacy in Federated Learning Systems (2024.emnlp-industry)
Copied to clipboard
| Challenge: | Differential privacy (DP) and federated learning (FL) are used for language models training in production mobile keyboard applications. |
| Approach: | They propose a variant of DP-FTRL that uses a correlated noise mechanism to train on-device language models. |
| Outcome: | The proposed method improves privacy-utility trade-off and memory efficiency over existing FL methods while simplifying usage requirements and reducing memory. |
How reparametrization trick broke differentially-private text representation learning (2022.acl-short)
Copied to clipboard
| Challenge: | Differential privacy (DP) is a formal mathematical treatment of privacy protection . it guarantees how much privacy can be lost in the worst case . adapting DP mechanisms to NLP properly is largely non-trivial task . |
| Approach: | They propose to use differential privacy to learn text representations using DPText to quantify and guarantee how much privacy can be lost in the worst case. |
| Outcome: | The proposed methods are falsely claimed to be differentially private and violate privacy loss guarantees. |
TextMixer: Mixing Multiple Inputs for Privacy-Preserving Inference (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Pre-trained language models (PLMs) are often deployed as cloud services, enabling users to upload textual data and perform inference remotely. |
| Approach: | They propose a privacy-preserving inference framework called MixPi which aims to obfuscate a user's private input by mixing it with multiple other inputs. |
| Outcome: | The proposed framework surpasses existing privacy-preserving methods on token and sentence classification tasks. |
