Samsung has announced blockchain-based smart device security.

Samsung’s new security solution Knox Matrix will work as a user’s own private blockchain system and strengthen security through multi-layered mutual monitoring across connected devices, from smartphones to smart homes.

“Today’s connected world needs a connected security approach too — after all, if just one device is compromised, all others are at risk,” Shin Baik, principal engineer of the security team at the South Korean tech giant said during Samsung Developer Conference Wednesday. “Multi-device protection is the next battlefront for security and privacy.”
