Physcial Data
Data to Audio Cassette
Saving data to Audio cassette. Scarcity of resource? The basic principle is to convert either binary or Hex into audio signal, and then reverse the operation (simple......). Found a method for HAM Radio signals to transmit images, system is called Slow-Scan Television.
ctape
A ruby application for writing and reading plain-text on audio cassette or into analogue audio. Based on Commodore Datassette system.

Uses a sound software/framework called SOX
TODO : Need to learn how this works so that I may be able to modify, improve, or just learn.
Data to Light
Fibre. Morse.
Data to Image
Barcodes. Embedded information.
Encryption

Data Validation
Not really encryption but important in validation of "worth". Blockchain signatures.
Visual Cryptography
Using relatively simple analogue techniques to break an image into seemingly random noise. Article can be found here. Some more pragmatic, and diagrammatically obvious instructions can be found here.
OpenPGP
Opensource version of the Pretty Good Privacy encryption system. Uses asymmetrical keys to verify data access.
A beginners guide (and setup) can be found here. Opensource PGP encryption system GnuPG.
A comprehensive guide to PGP Encryption and usage instructions for GnuPG can be found here. Basic concepts are explained and usage instructions too.
Special Issue : Encrypt data as privacy is scarce. Very low level and only really a homage to security by creating an asymmetrical encryption with passphrase for people to try and read the document.
Decentralisation
Governance
Ecology
A very rich subject in regards to Scarcity of Resource.
