Secure Device & Signal Systems (DEAL 675)

Various techniques such as an anti-tamper system that detects physical interference or damage by triggering a protective action, a fingerprint-based authentication system for wireless networks, an HDMI device that selectively outputs video signals from either a master or a slave source through a single HDMI port, and an automated server recovery system that detects a corrupted system image, downloads a backup disk image from an external device, mounts it virtually, and restores the system without manual intervention. The technologies may be implemented in smart meters, payment terminals, data storage systems, smart home network systems, IoT device network access control systems, gaming consoles, data centers, cloud servers, blade servers, home theater systems, etc.
