I’m working on a project what requires around 1 to 2kb of data to be stored for ~80 years.
My thinking was a QR code (ECC H) etched into aluminium. Benefits being no bit rot & the assumption being cameras should still be commonplace in 80 years (And if QR isn’t a commonly used format anymore, surely an AI agent could easily write an app for the user).
Does anyone have any better suggestions or think I’ve missed anything.
1 to 2 Kb isn’t all that much. Write it down on acid free paper. Use plain ink with a good binder, neutral pH, UV resistance is generally optional in this case, but better. Better safe than sorry. Store it away from light in low humidity at temps <16 deg C. Seal hermetically. Use oxygen absorbers.
