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.
