Social data harvesting is malicious crowdsourcing

Social media platforms have been criticized for their collection of data through face recognition of people who don’t even hold accounts on these platforms. This malicious attempt against privacy is based on the data provided by actual users, which did have accounts on the platforms. Similarly, when neuroimaging matures, it might become feasible to reconstruct aspects of an individual which hasn’t been scanned from the knowledge and memories of individuals which have been scanned. This intriguing notion is explored in depth in Greg Egan’s “A Kidnapping.”
