🔒 The Problem

Modern digital security requires users to memorize increasingly complex numeric codes, creating a fundamental tension between security and usability.

  • Complex codes are secure but difficult to remember
  • Simple codes are memorable but vulnerable to attacks
  • Memory failures can lead to permanent loss of digital assets
  • Certain user groups (children, elderly, cognitively impaired) face additional challenges
  • High-stress situations make recall even more difficult

Real Impact: Millions of dollars in cryptocurrency lost due to forgotten private keys, device lockouts from forgotten PINs, and security breaches from weak passwords.

💡 Our Solution

We introduce a systematic approach that leverages generative AI to create memorable visual mnemonics by blending familiar concepts.

  • Maps numbers to objects, organisms, and occupations
  • Creates composite images using conceptual blending
  • Generates distinctive, memorable visual anchors
  • Maintains security while improving memorability
  • Accessible to diverse user groups and abilities

Key Innovation: Automated generation of evocative imagery using AI tools like DALL-E, combined with cognitive principles of bisociation and trisociation.

🎨 Examples in Action

PIN Code Example (1427)
1427
Base-256: (5, 147) → Aloe + Guitar
Aloe Guitar Mnemonic
"Aloe-inspired Guitar"

A bisociated image combining the natural patterns of aloe with guitar design

Complex Number Example (12216814)
12216814
Base-256: (186, 105, 238) → Postman + Gazelle + Toy
Postman with Gazelle Toy
"Postman with Gazelle-inspired Toy"

A trisociated image blending occupation, organism, and object concepts

Social Security Number (123-45-6789)
123-45-6789
Base-256: [(7,91), (125,21)] → [(Anemone, Chalkboard), (Iguana, Ball)]
SSN Mnemonics
Two memorable images: "Anemone Chalkboard" + "Iguana Ball"
Cryptocurrency Private Key (132-bit)

12-word BIP39 → Base-256 → 9 bisociated image pairs
Cryptocurrency Key Mnemonics Grid
Nine memorable image pairs for complex private key storage

Each image represents paired concepts, creating a visual story for the entire key
