Systems and methods for secure transaction management and electronic rights protection

This invention describes a specialized computer component designed to keep information safe and ensure it's used only as authorized. It works by having a processor, secure memory, and dedicated hardware for encryption, generating random numbers, and blocking unauthorized access to its internal workings. This secure unit also authenticates any code it runs, creating a highly protected environment for handling sensitive data or managing digital rights.

Why it matters: Filed before widespread hardware-backed secure enclaves like Intel SGX or ARM TrustZone were common. These now provide the secure processing unit and memory isolation described in the claims, making the core technology more accessible for distributed secure environments.

Status: ExpiredProtection ended and was never renewed
How hard to build: SpecializedCustom silicon, secure memory, dedicated hardware engines
