Description: As cloud computing and data outsourcing become increasingly prevalent, the need for data privacy is critical. Homomorphic encryption allows for algorithms and analytics to be computed on outsourced encrypted data without leaking any information about the underlying plaintexts, while zero-knowledge proofs allow for data verification without revealing secret data to the other party. In this talk, the presenters will briefly introduce these two technologies and discuss state-of-the-art applications utilizing HE and ZKP. Homomorphic encryption techniques can be used to conduct private machine learning inferences on the cloud without revealing any information about user inputs. For instance, a user could encrypt a picture of a patch of skin, upload it to a cloud server, and receive an inference result indicating whether or not he has skin cancer without ever exposing the picture itself. In terms of ZKP, a user could prove that she casted her vote correctly without revealing who she voted for. This enables building secure and trustworthy electronic voting.
