Devices, systems, and methods for securing and transacting cryptocurrency assets

This invention describes a system to make cryptocurrency transactions more secure. It uses two main parts: a regular computer or phone with a software application that holds your public cryptocurrency address, and a separate, specialized hardware device that securely stores your secret private key. When you want to make a transaction, the hardware device temporarily connects to your computer to digitally sign the transaction using your private key, and then your computer broadcasts it. The claims specifically mention that the hardware device can include a fingerprint or eye scanner for user authentication.

Why it matters: Filed before widespread integration of biometric sensors into secure hardware and consumer devices. The claims for biometric authentication are now more readily implementable with commoditized secure elements and biometric modules.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSecure hardware, custom firmware, software logic, biometrics
