30 years out in the future seemed far out. But here we are on Oct 21, 2015 when Marty arrives back to the future.
What were some security features in the movie ?
- Thumbpads or fixed fingerprint scanners are used as a door locks. They are well integrated in the life of people.
- Vehicle had barcode license plates that were remotely scannable. This could allow remote scanning by other vehicles or building infrastructure.
- Police carry mobile fingerprint scanners to identify a person – they press their thumb and obtain the name, address and date of birth.
- An autonomous drone walks the dog and apparently is safe enough on the roads.
How does Marty identify the characters in a different age ? It is interesting to think about identification schemes that can last for decades. He first recognizes their mannerisms and relationships. Identification mechanisms are being built to leverage such signatures.
In Minority Report, there is personal advertising scene of the future which uses face/eye recognition to flash ads to Tom Cruise. https://www.youtube.com/watch?v=7bXJ_obaiYQ
