Google open source fully homomorphic encryption universal translator

Google announced the open source of the first fully homomorphic encryption (FHE) universal translator under the Apache License 2.0 license. Fully homomorphic encryption allows specific algebraic operations to be performed on the ciphertext to obtain the result of the encryption, which is the same as performing the same operation on the plaintext and then encrypting the result. This technology can perform operations such as retrieval and comparison among encrypted data, and there is no need to decrypt the data during the entire processing. Homomorphic encryption technology fundamentally solves the confidentiality problem when entrusting data and its operations to a third party. Today's files are usually encrypted during transmission and storage, and decrypted during use. There are security weaknesses. FHE can solve this problem. FHE can also use sensitive data to train machine learning models in a private manner.
