SSenStone is the developer and provider of an integrated user authentication system StonePASS. Under the premise that any system can be susceptible to information leakage, the company has developed a 2-way dynamic key-matching algorithm to guarantee smooth user authentication even in case of user information leakage. This patent-protected technology is the first to integrate all existing security technologies—including password-authentication, online payment, OTP, SMS replacement, bio-authentication, SSO—and to be native to blockchain, cloud computing, mobile, and IoT environments. With SSenStone’s solution, developers no longer need to sweat over adopting multiple authentication technologies for different platforms.
