Invented in IBM Research, Fully Homomorphic Encryption (FHE) is the first and only known technology that enables the processing of data in its encrypted form, thus completing the triad of keeping data encrypted while in transit, at rest and during processing. Now the data and any intermediate value remain encrypted while in memory and in the registers of the CPU. FHE unlocks the potential for cloud use, even for the regulated industries. In this session, our speakers provide an overview of FHE and business applications and demonstrate how you can begin experimenting easily with a set of open-source FHE toolkits that help enterprise developers weave pervasive security into software source code. The toolkits support Linux for IBM Z as well as z/OS with Container Extensions. We conclude with technical demos shipped with the toolkits. These include Privacy-Preserving Search through a fully encrypted key-value store as well as a fully-encrypted machine learning for credit card fraud detection.
