OpenAI Works on Cryptographic Guarantees for Private Data Access

OpenAI president Greg Brockman told the Wall Street Journal's Joanna Stern in a July 29 YouTube interview that the company is developing "verifiable, auditable guarantees" that only its AI can review users' private data. The phrasing suggests cryptographic or confidential computing mechanisms rather than policy commitments alone. Brockman offered no architectural detail or timeline.
