This article is about the security-enhancing software naming systems. For the shorter or diminutive form of a word or given name, see Hypocorism. For names of pet animals, see Personal name § Non-human personal names.

Petname systems are naming systems that claim to possess all three naming properties of Zooko's triangle - global, secure, and memorable.[1] Software that uses such a system can satisfy all three requirements. Such systems can be used to enhance security, such as preventing phishing attacks.[2] Unlike traditional identity systems which focus on the service provider, Petname systems are decentralized and designed to facilitate the needs of the enduser as they interact with multiple services.[3][4]

History[edit]

The Petname model was formally described in 2005 by Mark Stiegler however the potential of the system was discovered by several people successively.[3]

Examples[edit]

PetName Markup Language[edit]

The PetName Markup Language (PNML) is a proposal for embedding Petname information into other systems using a custom markup language.[4]

PNML consists of two tags:

  • <pn>pet-name-string</pn>
  • <key>stringified-cryptographic-key</key>
