KTDI is a “surveillance-by-design” vision for tracking and control of travelers more dystopian than anything we have seen before. 
KTDI would use a blockchain-based distributed ledger to bind together, through an app on a traveler’s mobile device, all of the following data:
- Biometrics (initially facial images, possibly also fingerprints, etc.)
- Government-issued ID credentials (passport number, etc.)
- Travel history including logs of border crossings, hotel stays, and possibly also car rentals and/or other events
- Purchase logs and possibly bank account information and/or other financial and transaction records
- Pre-crime predictive “risk assessment” and profiling scores generated at each “intervention” point before and during each trip or transaction
