Space and Time launches platform for AI verification of private data

The Microsoft-backed project's new enterprise product lets companies prove their AI calculations are correct without exposing the underlying records Space and Time, a blockchain data project backed by Microsoft, wants to solve one of the more awkward problems in corporate AI: how to let a machine use your data without handing it the keys to the vault. The company announced on Monday the launch of Space and Time Enterprise. The platform lets businesses run AI tools on private data while keeping the raw records out of reach. The pitch is simple, even if the cryptography behind it is not. Companies can prove that a calculation performed on their private database is correct. AI applications, auditors and other stakeholders can then check that result without ever touching the database itself. How the new platform works Space and Time Enterprise generates cryptographic proofs for SQL query results, which serve as mathematical receipts showing the answer was computed correctly from the data on file. SQL, for the uninitiated, is the standard language businesses use to pull information out of databases. Ask a question in SQL, get an answer back. The new system attaches a proof to that answe...
