"digital in-memory compute: digital IMC chip performs computations inside device's memory where pieces of machine-learning model stored after being moved over from central server... data split into random pieces, re-used without adding more pieces, lightweight cipher encrypts model stored off-chip, generated key decrypting cipher directly on chip... resists millions hacking attempts, cipher remained unbreakable, slightly more expensive and less energy-efficient... health-monitoring, financial, AR VR, autonomous driving"
