Old School Low Metadata Conversation, Result of ChatGPT-Me Conversation

Hacker News - Sun, 11/03/2024 - 3:04pm

Objective

To set up exact, low-metadata communication between two private devices, Redmi 13 and Mobile X, using an old-school private code akin to Windtalker-style communication, which does not rely on modern digital encryption. This approach leverages human language, codes, or phrases understood only by the involved parties. Devices Involved

Redmi 13: A Xiaomi smartphone configured for privacy. Concrete: Disable call and SMS logs via phone settings or apps like CCleaner. Turn off GPS and location services in Settings > Location. Mobile X: A feature phone or simple smartphone. Concrete: Use a basic model like Nokia 105 for minimal data retention, configured for calls and SMS only. Limit the contacts to just one labeled "13" for Redmi 13. SIM Information

Anonymous SIM: Utilize a prepaid, non-registered SIM. Concrete: Obtain these from regions where ID registration is not required, such as via SIMOptions or local shops in specific areas. Low-Metadata Setup

Ensure minimal retention of data on both devices: Concrete: Disable or auto-delete call logs using Call Log Monitor. Limit app permissions for calls, messaging, and location through Settings > Apps > App permissions. Old-School Cryptography (Windtalker Style)

Use a private spoken or written code, incorporating elements similar to the original Native American code talkers’ approach, where the language or symbols are understood only by the communicating parties. This type of code ensures secure communication without reliance on modern encryption or software. Overall Context

This approach ensures secure, low-metadata communication between two offline devices, using traditional, human-based codes for cryptography. The results will contribute to research on privacy-focused communication methods and will be shared publicly, providing insights into how historical cryptographic methods can be adapted for modern low-tech privacy needs.
