About the programme
Course Overview
Organisations increasingly need to combine data with suppliers, competitors, regulators or research partners to detect fraud, train shared models or benchmark performance, yet moving raw records outside a controlled boundary creates legal exposure and competitive risk that can stop a collaboration before it starts. This course gives participants a working knowledge of the privacy-enhancing technologies that make such collaboration possible without exposing underlying records: federated learning, differential privacy, secure multi-party computation, homomorphic encryption, trusted execution environments and data clean rooms. Sessions combine technical selection criteria with the governance a multi-party collaboration requires, including joint controllership agreements, cross-border transfer mechanisms and independent re-identification testing. Participants work through a realistic data-sharing design, choosing a technique, specifying query controls and drafting terms that let partner organisations trust a shared environment. The course closes with scaling practice, so a pilot between two organisations can grow into a multi-party consortium without redesigning its technical foundations. Participants leave able to design and govern a privacy-enhancing data collaboration from risk assessment through to production operation.
Expected Learning Outcomes
Design a federated learning or secure multi-party computation architecture that keeps raw data within each participant's boundary.
Configure a data clean room with query controls, aggregation thresholds and audit logging that partners can trust.
Draft data-sharing agreements and joint controllership terms that assign legal responsibility across collaborating organisations.
Assess re-identification risk using recognised statistical methods before releasing any shared analysis or model.
Build a data protection impact assessment that treats privacy-enhancing controls as evidence requiring independent verification.
Present a business case and governance model that lets an organisation scale data collaboration from a pilot to production.

01Foundations of Privacy-Enhancing Technology for Shared Data
2 sessions · 8 points
Session 1Data Collaboration Risk and the Case for Privacy Engineering
- Map cross-organisation data flows to identify where raw personal or commercial records would otherwise leave a controlled boundary.
- Distinguish anonymisation, pseudonymisation and de-identification and explain why each offers different legal protection under data protection law.
- Quantify re-identification risk using k-anonymity, l-diversity and linkage-attack scenarios drawn from published data-sharing incidents.
- Build a decision matrix that matches a collaboration's sensitivity and volume to a shortlist of candidate privacy-enhancing techniques.
Session 2The Privacy-Enhancing Technology Landscape
- Compare federated learning, secure multi-party computation, homomorphic encryption, differential privacy and trusted execution environments on maturity and cost.
- Explain how a data clean room enforces query-level controls so partners can run agreed analyses without seeing each other's underlying rows.
- Assess synthetic data generation methods, including generative adversarial networks and statistical resampling, for utility against the original distribution.
- Select a proof-of-concept technique for a two-party fraud-signal-sharing scenario and justify the choice against a rejected alternative.
02Designing Federated and Encrypted Collaboration Architectures
2 sessions · 8 points
Session 1Federated Learning and Secure Computation in Practice
- Design a federated learning topology that keeps training data on each participant's infrastructure and exchanges only model updates.
- Apply secure aggregation protocols to prevent a coordinating party from inspecting individual participants' gradient contributions.
- Configure secure multi-party computation for a joint benchmarking exercise, such as comparing salary bands without disclosing individual figures.
- Evaluate homomorphic encryption libraries for latency and computational overhead against a defined query workload.
Session 2Data Clean Rooms and Query Governance
- Specify the allow-listed queries, aggregation thresholds and output-perturbation rules that a data clean room must enforce before release.
- Draft a joint controllership agreement that assigns responsibility for lawful basis, retention and subject-access requests across partners.
- Build audit logging that records every query submitted to a shared environment together with the requesting organisation and purpose.
- Test a clean-room configuration against adversarial queries designed to reconstruct individual-level data through repeated aggregation.
03Governance, Risk and Legal Structuring of Multi-Party Data Sharing
2 sessions · 8 points
Session 1Legal Basis, Contracts and Cross-Border Transfer
- Identify the lawful basis for each participant's contribution under data protection law before any technical design begins.
- Draft data-sharing agreements that define purpose limitation, retention periods, deletion obligations and liability for a breach.
- Assess cross-border transfer mechanisms, including standard contractual clauses and adequacy decisions, for a multinational consortium.
- Coordinate with competition counsel to confirm that shared analytics do not amount to unlawful information exchange between competitors.
Session 2Risk Assessment and Independent Assurance
- Conduct a data protection impact assessment that treats the privacy-enhancing technology itself as a control requiring evidence of effectiveness.
- Run a re-identification stress test using an external red team before a collaboration moves from pilot to production.
- Define residual-risk acceptance criteria and the governance forum authorised to approve them on behalf of each organisation.
- Document technical and organisational measures in a form suitable for a regulator or an auditor to review after an incident.
04Operating, Scaling and Demonstrating Value from Data Collaborations
2 sessions · 8 points
Session 1Operating Model and Monitoring for Data Collaborations
- Establish a joint operating model with defined roles for data stewards, security leads and a collaboration governance board.
- Instrument ongoing monitoring that flags drift in output disclosure risk as underlying datasets and query patterns change over time.
- Plan an incident-response runbook specific to a multi-party environment, including notification duties owed to every partner.
- Retire or renegotiate a collaboration when its original purpose limitation no longer matches how partners are using the shared environment.
Session 2Scaling and Demonstrating Business Value
- Extend a proven two-party pilot to a multi-party consortium by renegotiating governance without redesigning the underlying technology.
- Build a business case that sets collaboration benefits, such as fraud losses avoided or shared demand forecasts, against implementation cost.
- Present a maturity roadmap that sequences additional privacy-enhancing techniques as data volume and partner count increase.
- Brief executive sponsors on residual risk and the conditions under which a data collaboration should be paused or withdrawn.
