selecting-privacy-enhancing-technologiesComprehensive PET selection guide covering differential privacy, homomorphic encryption, secure multi-party computation, federated learning, zero-knowledge proofs, and trusted execution environments.
Selecting Privacy Enhancing Technologies is an agent skill from mukul975/Privacy-Data-Protection-Skills. Comprehensive PET selection guide covering differential privacy, homomorphic encryption, secure multi-party computation, federated learning, zero-knowledge proofs, and trusted execution environments. Includes use-case matching matrix, performance comparison, and GDPR alignment assessment for each technology.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/standards.md` and `references/workflows.md`).
It sits in Legal & Compliance, covering Privacy and GDPR and Cryptography. The repository describes itself as: 282+ structured privacy & data protection skills for AI agents. GDPR, CCPA, EU AI Act, HIPAA, LGPD, PIPL, DPDP Act. The licence is Apache-2.0.
10 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 9b2ef9e. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Selecting Privacy Enhancing Technologies loads about 2.6k tokens when it runs, and up to ~5k if it reads all its reference files. Until then it costs about 88 tokens; SKILL.md has 1,174 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

The GDPR does not prescribe specific technologies but requires "appropriate technical measures" (Article 25(1), Article 32(1)) to implement data protection principles. The European Commission's February 2025 communication on PETs and the ENISA 2023 report on engineering privacy by design with PETs provide regulatory context for PET adoption.
Selecting the right PET depends on the processing scenario, data sensitivity, computational requirements, and the specific privacy property needed (confidentiality, anonymity, unlinkability, or transparency).
Privacy property: Statistical indistinguishability — the output of an analysis is approximately the same whether or not any individual's data is included.
| Characteristic | Detail |
|---|---|
| Approach | Add calibrated noise to query results or model gradients |
| Privacy guarantee | Mathematically provable (epsilon, delta) bounds |
| Data utility | Configurable via epsilon; lower epsilon = more privacy, less utility |
| Performance overhead | Minimal for query-time noise; moderate for DP-SGD training |
| Maturity | Production-ready (Apple, Google, US Census Bureau) |
| GDPR relevance | Supports Recital 26 anonymization when epsilon is sufficiently small; Art. 25(1) by design measure |
Best for: Statistical analytics, aggregate reporting, ML model training on sensitive data.
Libraries: Google DP Library, OpenDP, IBM diffprivlib, PyDP.
Privacy property: Computation on encrypted data — results are decrypted only by the data owner.
| Characteristic | Detail |
|---|---|
| Approach | Encrypt data such that mathematical operations on ciphertext produce valid results when decrypted |
| Privacy guarantee | Cryptographic (lattice-based hardness assumptions) |
| Data utility | Exact results (no noise added) |
| Performance overhead | High: 1,000x-1,000,000x slower than plaintext, depending on scheme and operation |
| Maturity | Emerging for production; active research on performance optimization |
| GDPR relevance | Art. 32(1)(a) encryption as security measure; enables processing without exposing plaintext to processor |
Schemes:
Libraries: Microsoft SEAL, IBM HELib, Google FHE (Fully Homomorphic Encryption transpiler), TFHE-rs, OpenFHE.
Privacy property: Joint computation without revealing individual inputs — each party learns only the final result.
| Characteristic | Detail |
|---|---|
| Approach | Secret sharing, garbled circuits, or oblivious transfer protocols |
| Privacy guarantee | Information-theoretic (for secret sharing) or computational (for garbled circuits) |
| Data utility | Exact results |
| Performance overhead | Moderate to high; depends on circuit complexity and number of parties |
| Maturity | Production deployments in financial services, healthcare consortia |
| GDPR relevance | Enables joint controllership (Art. 26) analytics without data sharing; supports data minimization (Art. 5(1)(c)) |
Frameworks: MP-SPDZ, CrypTen (Meta), MOTION, ABY/ABY3, Sharemind.
Privacy property: Model training without centralizing data — raw data never leaves the data owner's environment.
| Characteristic | Detail |
|---|---|
| Approach | Distribute model training to data owners; aggregate only model updates (gradients) |
| Privacy guarantee | Data locality (raw data stays on device); strengthened with secure aggregation and DP |
| Data utility | Depends on data distribution across participants (IID vs non-IID) |
| Performance overhead | Communication overhead for gradient exchange; multiple training rounds |
| Maturity | Production at Google (Gboard), Apple (Siri), hospitals (NVIDIA FLARE) |
| GDPR relevance | Supports Art. 5(1)(c) minimization; reduces cross-border transfer requirements (Chapter V) |
Frameworks: TensorFlow Federated, PySyft (OpenMined), NVIDIA FLARE, Flower, FedML.
Privacy property: Prove a statement is true without revealing the underlying data.
| Characteristic | Detail |
|---|---|
| Approach | Prover demonstrates knowledge of a secret (e.g., age ≥ 18) without revealing the secret (date of birth) |
| Privacy guarantee | Soundness (false statements cannot be proven) and zero-knowledge (verifier learns nothing beyond the statement's truth) |
| Data utility | Binary verification (proof valid/invalid); no data disclosed |
| Performance overhead | Proof generation: moderate to high; proof verification: fast |
| Maturity | Production in blockchain identity; emerging in enterprise identity verification |
| GDPR relevance | Ultimate data minimization — prove compliance without disclosing data; supports Art. 5(1)(c), Art. 25 |
Systems: zk-SNARKs (Groth16, PLONK), zk-STARKs, Bulletproofs.
Privacy property: Isolated computation — data is processed inside a hardware-protected enclave that even the system administrator cannot access.
| Characteristic | Detail |
|---|---|
| Approach | Hardware-enforced isolation using secure enclaves (Intel SGX, AMD SEV, ARM TrustZone, AWS Nitro) |
| Privacy guarantee | Hardware-based attestation and memory encryption |
| Data utility | Full computation capability inside enclave |
| Performance overhead | Low to moderate; limited enclave memory may require data streaming |
| Maturity | Production: Azure Confidential Computing, AWS Nitro Enclaves, Google Confidential VMs |
| GDPR relevance | Art. 32(1)(a) encryption in processing; Art. 28 processor guarantees; protects against insider threats |
| Use Case | DP | HE | SMPC | FL | ZKP | TEE | Recommended Primary |
|---|---|---|---|---|---|---|---|
| Aggregate analytics on customer data | 5 | 2 | 3 | 2 | 1 | 3 | Differential Privacy |
| ML model training on distributed hospital data | 3 | 1 | 2 | 5 | 1 | 3 | Federated Learning |
| Credit scoring without sharing financial records | 2 | 3 | 5 | 2 | 2 | 3 | Secure MPC |
| Age verification without revealing date of birth | 1 | 1 | 1 | 1 | 5 | 2 | Zero-Knowledge Proofs |
| Processing encrypted customer data in third-party cloud | 2 | 5 | 2 | 1 | 1 | 4 | Homomorphic Encryption |
| Anti-money laundering across banks | 2 | 2 | 5 | 3 | 2 | 3 | Secure MPC |
| Private genomic analysis | 3 | 4 | 3 | 3 | 1 | 4 | HE + TEE combination |
| Confidential inference on cloud-hosted ML models | 2 | 4 | 2 | 1 | 1 | 5 | Trusted Execution Environment |
| Privacy-preserving surveys and polls | 5 | 1 | 3 | 1 | 2 | 1 | Differential Privacy |
| Secure keyword search on encrypted database | 1 | 4 | 1 | 1 | 1 | 4 | Homomorphic Encryption |
Scores: 1 = poor fit, 5 = excellent fit
Many production deployments combine PETs for defense in depth:
| Combination | Benefit |
|---|---|
| FL + DP | Federated learning with differentially private gradient updates prevents gradient inversion attacks |
| FL + Secure Aggregation | Aggregation server never sees individual gradients |
| HE + TEE | Process encrypted data inside an enclave for double protection |
| SMPC + DP | Add noise to SMPC outputs for formal anonymization guarantee |
| ZKP + TEE | Prove computation was performed correctly inside an enclave without revealing inputs |
