Private by Design

Without security, there is no privacy. Worldcoin is about enabling people to be online without having their identities exposed and empowering them to distinguish between bot-based interactions and human ones. Security helps make sure that level of privacy is achieved—every time, without fail. World ID uses many security techniques to ensure the data security of World ID holders. One set involves human tools, such as open-sourcing and audits (see: Transparency), which help validate and pressure test the security measures that have been created and implemented as part of the Worldcoin project. The other set includes cryptographic tools, such as ZKPs and SMPC (see: Anonymity), which use advanced mathematics to secure data, encrypt it, and keep it private or render it anonymous. SMPC is one of the few results in cryptography that can provide perfect secrecy. ZKPs, meanwhile, use nullifier hashes, or unique values, for each application so that people’s usage history can’t be tracked. Call it secured by math.
