certSIGN, a Romanian company specialized in encryption solutions, has obtained an invention patent for a homomorphic data encryption method that allows data to be processed without the need to decrypt it. The patent was granted by the Patent and Trademark Office of the United States of America and has the number US10454668 of October 22, 2019.

Unlike classic encryption solutions, where data to be processed is first decrypted, then analyzed and processed and in the end re-encrypted, a process that can give rise to security breaches, with homomorphic encryption the data remains encrypted throughout the processing.
