The technology carries significant computational overhead, though Google says the cost of homomorphic encryption is decreasing, making it practical for privacy-preserving data processing in fields such as <a href=\"https:\/\/www.helpnetsecurity.com\/2026\/06\/26\/cyber-incident-healthcare-vendor-risk\/\" rel=\"nofollow noopener\" target=\"_blank\">healthcare<\/a> and finance.<\/p>\n<p>FHE development and optimization<\/p>\n<p>HEIR has grown into a platform for homomorphic encryption development and research since Google announced its plans for the project in 2023. It provides infrastructure for performance testing and benchmarking and has supported collaborations between Google and academic researchers. Google says four peer-reviewed publications have been built on HEIR, with more in preparation.<\/p>\n<p>The project aims to simplify the development, optimization, and deployment of fully homomorphic encryption (FHE). It is designed to support multiple FHE schemes, libraries, and front-end programming languages. Its project goals also include code generation for hardware accelerators such as GPUs, TPUs, FPGAs, and custom ASICs. HEIR provides infrastructure for performance benchmarking and research into FHE optimizations.<\/p>\n<p>Homomorphic encryption in practice<\/p>\n<p>HEIR demonstrates the use of homomorphic encryption in private recommendations, credit card fraud detection, network intrusion detection, and hotword recognition. These applications allow systems to analyze sensitive data without exposing its contents during computation.<\/p>\n<p>Developers can write programs in Python, identify sensitive data, and use HEIR to compile the programs into implementations that operate on encrypted data. Hardware designers can integrate accelerators at different stages of FHE computation. Cryptography researchers can use HEIR\u2019s compiler infrastructure to build, test, benchmark, and compare cryptographic optimizations.<\/p>\n","protected":false},"excerpt":{"rendered":"Google\u2019s researchers and engineers developed the Homomorphic Encryption Intermediate Representation (HEIR) compiler project, an open-source compiler toolchain and&hellip;\n","protected":false},"author":2,"featured_media":143267,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[24,8914,132,1429,335],"class_list":["post-143266","post","type-post","status-publish","format-standard","has-post-thumbnail","category-google","tag-ai","tag-encryption","tag-google","tag-google-ai","tag-open-source"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/143266","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/comments?post=143266"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/posts\/143266\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media\/143267"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/media?parent=143266"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/categories?post=143266"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/ai\/wp-json\/wp\/v2\/tags?post=143266"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
