DID, PCAP and Reputation Score

Parami Decentralized Identity

Parami Protocol provides a complete set of PDID (Parami DID) solutions compatible with W3C DID standard on Parami Node, and expands its business on the basis of DID standard. Parami Protocol will also provide DID aggregators for other DID standards.

• NO KYC: PDID allows users to verify DID uniqueness by building social graphs and running anti-sybil analysis without any KYC process.

• DID on WEB 2.0: Parami DID provides a verification method that can connect to users’ WEB 2.0 social identities. At the same time Parami DID provides a way to be recognized in WEB 2.0 worlds.

• DID on WEB 3.0: Parami DID provides a verification method that can connect to users’ WEB 3.0 multi-chain addresses. At the same time Parami DID, can be recognized in WEB 3.0 worlds which support DID specification

ZKP Based User Data Privacy

AD Privacy Layer provides a personal crypto advertising preference (PCAP) document attached to user DID, which contains user advertising privacy management service. The PCAP document works not only for payment but also for user preference data. The preserved data can be used but can not be seen.

• Blind Signature

Advertisers use blind signature to prove they have confirmed user interaction with AD, which avoid further malicious behavior.

• Homomorphic Encryption

User crypto advertising preference (PCAP) data is homomorphic encrypted so that advertisers could update users’PCAP in an encrypted way.

• Zero-Knowledge Proof

The Zero-Knowledge Proof （ZKP）algorithm is used so that users can get the reward he/she deserves. The ZKP generates the corresponding proof and verifiy it on-chain to determine the reward.

• Data Aggregator

Aggregate user data from both social identity and blockchain identity

PCAP & Reputation Score

Parami provides decentralized oracle to collect data from conventional Internet for Ad verification. It also defines the interfaces for tokenized advertising dapp to get AD privacy support.

PCAP (Personal Crypto Advertising Preference)

• PCAP data fetch/update: Dapp can fetch PCAP data (ZKP) of some DID to determine and verify the user reward he/she deserves. PCAP data update:

• Dapp can also update (scoring some tags) PCAP data each time it sends reward to users, with updated data encrypted homomorphically.
