Yes, calling out linkage as a key challenge for data privacy is very important. To dig in one level deeper... Have you looked into privacy-preserving record linkage (PPRL) or similar ideas? (I have not, but I'm interested.) > The process of linking records without revealing any sensitive or confidential information about the entities represented by these records is known as privacy-preserving record linkage (PPRL). > Source: "Privacy-Preserving Record Linkage". > DOI: https://doi.org/10.1007/978-3-319-63962-8_17-1 https://doi.org/10.1007/978-3-319-63962-8_17-1 See also: "A taxonomy of privacy-preserving record linkage techniques" at https://www.sciencedirect.com/science/article/abs/pii/S0306437912001470 https://www.sciencedirect.com/science/article/abs/pii/S03064...
