New Solutions to Biomedical Data Sharing: Secure Computation and Synthetic Data
- Jan 01, 2022
- Edwin Morley-Fletcher
An essential precondition for Artificial Intelligence applications in health is the possibility of having recourse to Big Data. The inconvenient truth, however, is that ever-growing quantities of biomedical data sit idle in fragmented silos, and their use is hindered, among other things, by the need to act in compliance with the General Data Protection Regulation. A recent H2020 Research and Innovation project, MyHealthMyData, highlighted two privacy-enhancing technologies which can provide new solutions for data sharing in health. The first is based on bringing the algorithms to the data in what is called the “visiting mode”, based on secure computation mechanisms, by which only the outcomes are released, not the original data. The second approach leverages the capacity of producing synthetic data through generative adversarial neural networks, adding a further non-reidentification guarantee by making use also of differential privacy. Synthetic data generation and secure computation may thus complement the GDPR by developing an ecosystem in which health data can safely provide the Big Data needed to fully make use of AI in medicine.KeywordsArtificial IntelligenceBig DataAnonymisationPseudonymisationData SharingPersonalised MedicineSecure ComputationSynthetic DataDifferential Privacy
