US Patent 10944547 Secure environment device management

A method manages software images in a blockchain-based environment of trusted devices. A trusted device creates a software image for sharing among members of a set of trusted devices that includes the trusted device. A blockchain mechanism stores the software image on a virtual machine that is in communication with the set of trusted devices, where the blockchain mechanism uses the set of trusted devices as peer members of the blockchain mechanism. A trusted device from the set of trusted devices receives, via the virtual machine, an access request for the software image from a requesting device from the set of trusted devices. The blockchain mechanism authorizes the access request by providing the software image to the requesting device.
