THEKEY Project is now developing an identification verification (IDV) tool with blockchain based dynamic multi-dimension identification (BDMI) by using Personally Identifiable Information (PII) which is exclusively authorized by government authorities. THEKEY is a decentralized ecosystem of identity verification tool using national big data and blockchain. BDMI stands for Blockchain-based Dynamic Multi-Dimension Identification technology, which aims to set up a powerful and cost-efficient identity verification tool for internet. The ultimate objective of BDMI is to generate undeniable and unalterable IDV results.

BDMI embraces the following 6 elements to deliver the perfect solution for IDV:

• Unique biometrics data serves as the base of BDMI
• The data of BDMI used, including biometrics data, for IDV are all validated in advance by relevant government authorities
• The data of BDMI used for IDV are comprehensive enough so that it can meet the different requirements of various clients
• To ensure the reliability of BDMI, cross-check is always carried out during IDV between the government validated data and behavior/scene data of the same user
• To ensure solidity, BDMI always uses updated data when an IDV is executed, to capture the latest changes, if any
• Once an IDV is completed the result will be properly documented for audit so that the personal credit of the user can be evaluated and calculated.
