Among the cryptographic technologies under development in various industries, homomorphic encryption (HE) possesses the attractive feature of allowing computation within the encrypted domain. Encrypted data cannot only be transferred and stored, but also used in the secure encrypted state. This state-of-the-art technology has evolved rapidly over the past decade with new breakthroughs every year since the first functional implementation in 2009. The technology has already been proposed for face recognition and in other domains where a high level of privacy is mandatory. This article presents the main principles of HE, as well as the benefits that can be leveraged from this technology for th
