The document discusses security risks in data storage for IoT systems. It notes that while communication protocols and sensors have security, data storage faces few safeguards and is vulnerable. Hackers could access large amounts of personal data by breaching a single storage point. The document proposes a solution of encrypting and distributing data across separate storage locations with tight access controls. This would require changes to current business models that rely on centralized data storage. Visionary companies are working to address privacy and security issues in IoT to enable continued business growth and user adoption.
