Portable consumer device configured to generate dynamic authentication data

This is a small, portable device designed to hold and manage security information. Every time it connects to an external power source, it automatically reads this information, updates it using a built-in algorithm stored in its memory, and then saves the new information back. The device also transmits this updated security data to the external device it's connected to.

Why it matters: Filed before the widespread adoption of secure hardware tokens for digital assets and decentralized identity. The described mechanism for dynamically updating authentication data on external power is now a foundational requirement for protecting cryptographic keys in modern hardware wallets and secure identity devices.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom silicon, secure firmware, integrated circuit
