Japan's BaaSid Lab Japan Co., Ltd. recently announced that its main network has launched BaaSid, a personal authentication service that manages personal information in blockchain. The company also announced that it has successfully connected the core technology of BaaSid, the separation and dispersion engine. BaaSid is a mechanism for encrypting, segmenting, and distributing management of personal information (including authentication data). When user authentication is performed in various services, fragment data is collected on the user's device to restore the authentication data. Automatically destroy data from the device after authentication is complete, reducing the risk of data leakage.
