U.S. Patent 10482236 was awarded to Capital One Services, LLC on November 19, 2019 and is entitled “Methods, mediums, and systems for establishing and using security questions.” The first named inventor is Kate Key of Effingham, IL. The abstract contains an overview of the patent disclosure:

Exemplary embodiments relate to the secure storage of security questions through an immutable log, such as a blockchain. The security questions may be stored in a centralized location, accessible from an application or browser tab running on the user’s device. When a security question is required, such as to perform a password reset on a website, the website may interact with the application or browser tab, which retrieves the question(s) from the blockchain. The user may enter their answers to the question(s), which may be hashed by the application or tab. The hashed answers may be entered into the original requesting website, which may verify with the blockchain that the correct answers have been provided. Thus, the requesting website sees neither the questions nor the answers. Additional security features may include logging requests for questions, so that a user can determine if a security question may have been compromised. Link to Full Patent
