Organizations are starting to take an interest in homomorphic encryption, which allows computation to be performed directly on encrypted data without requiring access to a secret key. The technology isnt new (it has been around for more than a decade), many of its implementations are. Some existing deployments, particularly in financial services and healthcare, are worth studying to see how effective it can be at solving privacy problems and delivering actionable data insights. Because the encryption algorithms use problem-solving complex mathematics, they take more time to process transactions.”]
