Latest Patents

Xianhang Zhang holds a patent titled "Access control by testing for shared knowledge." This patent introduces a method for controlling access to resources intended for specific groups of individuals. Instead of relying solely on accounts and access control lists, this system utilizes concise tests of shared knowledge. Users can easily learn the concept and select questions that will manage access for the desired group with minimal effort. The questions are designed to be relatively secure against guesses from unauthorized individuals, especially when the number of allowed guesses is limited. Users can generally assess the security of their questions, although they may underestimate the capabilities of attackers who can use web searching or enumeration to find answers. The system can automatically identify weak questions and suggest alternatives, thereby enhancing security. By lowering the threshold for access control, shared knowledge tests can facilitate the collaborative value of information on the Internet and other networks.
