Vitro IoT employs integrated ECC hardware cryptography in small, low power, low cost devices that interface with any type of digital device (e.g. scanners, cameras, sensors, scales, meters) to capture and secure verified data at the source. Verified data is assembled into authenticated IoT Blocks: data encrypted, hashed and signed with Proof-of-Origin for secrecy and security in transport and at rest. A hosted ''oracle'' decrypts IoT Block data through Zero-Trust (IAM) authenticated access by users and applications.
