Physical Data Security
Secure Storage of Documents: Keep physical maps, journals, or records in locked boxes, hidden compartments, or buried caches. Hide crucial notes inside hollowed books or beneath false floors.
Code and Cipher Notes: Simple substitution ciphers, symbolic codes, or shorthand can render your notes useless to a casual finder. Ensure the code i s memorable to you but inscrutable to others.
Lamination and Waterproofing: Protect vital papers from moisture and wear. Storing them sealed in plastic bags or waterproof cases ensures longevity and reduces accidental destruction.
For especially sensitive info, write it in fragments scattered across multiple locations. Only you know how to piece them together, thwarting easy interpretation by finders.
Digital and Physical Data Security
In a destabilized world, information can become as valuable—and dangerous—as material resources. Knowledge of safe routes, hidden caches, allies’ identities, and strategic plans can empower you, but if it falls into the wrong hands, it can also spell disaster. As traditional safeguards collapse and electronic systems become unreliable or compromised, securing both digital and physical data demands extra vigilance.
But once revealed, these insights might attract bandits or rival groups.
OpSec (Operational Security) Mindset: Embrace the principle of “need-to-know.” Even well-intentioned individuals might leak information unintentionally. Minimizing who knows what reduces the risk of leaks.
Always ask yourself: “If someone else found this information, how could they use it against me?” If the answer is bad, secure it better.
Protecting Digital Collections
Redundant Hardware: Multiple Media Types: USB + SD card + external HDD. If one fails, others might survive. Geographic Dispersion: Keep a copy in another physical location or hidden cache.
Corruption and Data Loss Prevention: Checksums and ECC: Use hashing (SHA256) or PAR2 files to detect and repair corruption. Periodic Test Reads: Plug drives in occasionally to ensure files open correctly.
Encrypted Containers: Protect sensitive data with passwords. Even if found, it won’t be easily misused.
Check if materials would remain intact if sprayed lightly with water (simulated rain infiltration).
Gather Feedback from Allies (If Any): If others have similar setups, exchange notes on best containers, best practices, and solutions to common issues.
Continuous Improvement: Preservation isn’t a one-time setup. Adapt as you learn better storage techniques or discover new threats.
Digital Security and Encryption
Passwords and Encryption: Protect digital archives with strong passphrases. Even if a drive is found, without the key, data remains unreadable. Store password hints or keys separately, or teach them orally to trusted allies.
Redundant Copies in Hidden Locations: Keep encrypted backups off-site. If one vault is compromised, another remains safe.
Steganography: Hide sensitive documents inside innocuous files—like embedding a crucial formula inside an image’s pixel data. If discovered, it’s less obvious.
Memorized Keys: For vital secrets, memorize certain decryption keys rather than writing them down, reducing the risk if archives are found.
Hardware and Media Considerations
Media Lifespan: Optical Discs (Archival-Grade): Gold-layered discs can last decades if stored properly.
Solid-State Drives (SSDs): Good for read stability but can fail suddenly. Store multiple copies.
Removable Storage (USB/SD): Quality Over Cheap: Invest in reputable brands—fewer random failures.
Write Protection Switches: On SD cards, a physical lock can prevent accidental overwrites.
Refreshing Media: Migrate Data Every Few Years: Move files to fresh drives or discs before old media degrades.
Test Reads: Randomly read files every 6-12 months to detect any developing issues.
Buried Caches: Underground storage provides temperature stability and some shielding from solar flares or radiation events.
Fire and Water Damage: Waterproof Bags and Cases: Keep SD cards, USB sticks in sealed bags.
Dust and Debris: Gaskets and Seals: Simple rubber gaskets on containers keep dust out.
Clean the Contact Pins: Periodically wipe connectors with alcohol swabs to ensure good electrical contact.
Test access and recovery together
Trace an important record from creation to backup and deletion. Identify authorized users and what happens if the device, account, or custodian becomes unavailable. Protect sensitive information while ensuring authorized people have a workable recovery process.
Test recovery with a non-sensitive sample. Confirm the copy opens, instructions are understandable, and required credentials can be retrieved through the agreed process. Keep public coordination information separate from private records. When roles change, update permissions and recovery details together. Security that blocks unauthorized use but also permanently prevents intended users from reaching essential records has not solved the full problem. Document the successful test and when it should be repeated.
