"No Keys to the Kingdom: New Single Sign-On Algorithm Provides Superior Privacy"
Researchers from the Tokyo University of Science (TUS) have developed a new single sign-on (SSO) algorithm that prevents the disclosure of a user's identity and personal information to third parties. SSO systems provide users the option to access different services and applications, using a single set of credentials (username and password). For example, one may log onto a website using their Facebook or Gmail login credentials. However, SSO systems are third party systems often managed by Big Tech companies who have been reported to collect personal information without users' permission for purposes such as targeted advertising. This article discusses the advantages of SSO systems, the concerns surrounding these systems, and TUS researchers' proposed cryptographic scheme to hide sensitive information from third parties when accessing services via SSO systems.
