Google’s open-source HEIR lets AI work with data it can’t see

Google released HEIR, an open-source compiler toolchain for homomorphic encryption that converts pre-trained AI models to process encrypted data without decrypting it. The platform, developed by Google researchers and engineers, targets application developers, compiler engineers, hardware designers, and cryptography researchers building privacy-focused software. Staff Software Engineer Jeremy Kun said cryptographers building on HEIR can focus on their core work.

Google’s researchers and engineers developed the Homomorphic Encryption Intermediate Representation HEIR compiler project, an open-source compiler toolchain and development platform for homomorphic encryption. It can convert pre-trained AI models designed to operate on unencrypted data into models that process encrypted inputs. The platform helps application developers, compiler engineers, hardware designers, and cryptography researchers develop privacy-focused software systems.
