Petname
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
Though the Petname model was formally described in 2005 by Mark Stiegler, the potential of the system was discovered by several people successively.[3]
Examples
- The GNU Name System (GNS) – a decentralized alternative to DNS based on the principle of a petname system[5]
- CapDesk – a distributed desktop environment[6]
- Petname Tool (discontinued browser extension) – There was a browser extension available for Firefox called Petname Tool that allowed pet names to be assigned to secure websites. Use of this extension could help prevent phishing attacks.[7]
PetName Markup Language
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>
