The Executive Identity Control Plane: Why Voice, Video, and Email Are No Longer Approval Channels

The article discusses the security risks of using communication channels like voice, video, and email as approval mechanisms for high-value business actions. It highlights how generative AI can create convincing deepfakes, making it difficult to rely on human recognition. The author proposes an 'executive identity control plane' that separates communication from authorization, requiring phishing-resistant authentication, transaction-specific signing, independent verification, and other safeguards. This approach ensures that critical actions are only executed with verifiable cryptographic intent, not just a familiar face or voice.
