IBM said on Thursday that the new FHE solution, IBM Security Homomorphic Encryption Services, will allow clients to start experimenting with how the technology could be implemented to enhance the privacy of their existing IT architecture, products, and data. FHE, considered by some as the "Holy Grail" of encryption, as it is a form of encryption that allows data to remain encrypted when being processed. The concept behind FHE is to plug the gap between securely-encrypted data held in storage and the need to decrypt while this information is in use -- a requirement in data processing or analysis -- which can create protection issues.
