The Secret Security Chip Hidden in Your Memory Card

This patent from Giesecke & Devrient (2007) reveals the clever engineering behind modern secure memory cards. It describes a method to add security features like encryption and authentication to standard SD cards without requiring any special drivers. The innovation uses "routing information" - invisible tags that direct data either to regular storage or to a hidden security chip. This technology enables DRM protection, secure authentication, and encrypted storage on memory cards that work in any device. #patent #technology #security #encryption #sdcard #memorycard #innovation #engineering #smartcard #cybersecurity #tech #invention #germanengineering #datasecurity #hardware #embedded #cryptography #authentication #drm #storage
