Decentralized identity (DID) is a blockchain-based identification system that normally generates and gives unique digital identities for individuals. DID was rarely given to objects and structures as the digital identification system is mainly used by online services for the authentication of users.
SK Telecom (SKT) said in a statement on June 7 that the company has formed a consortium with other companies and organizations including City Labs, a smart city solution developer, and Fire Insurers Laboratories of Korea to carry out a state building safety project in Jungnang District in eastern Seoul.
Using "Initial," the company's blockchain-based mobile identity authentication service and internet of things (IoT) devices, the consortium will monitor the structural integrity including large cracks and the slope of old buildings. SKT's mobile DID system can give digital identity to IoT devices to prevent hacking or forgery.
"Through our mobile DID service, we opened a new era of object DID for the first time in South Korea," SKT's blockchain and authentication service division head Oh Se-hyeon was quoted as saying. Oh said that SKT will continue to develop DID technologies so that the blockchain-based technique can be adopted by various fields including people's everyday lives.
