  • Patent number: 10541993
    Abstract: Disclosed are various embodiments that perform confidence-based authentication of a user. An identification of a user account is obtained from a user, and a minimum confidence threshold is determined. Multiple authentication challenges are presented to the user. Responses are obtained from the user to one or more of the challenges, with each response having a corresponding authentication point value. A confidence score is generated for the user, where the confidence score is increased by the respective authentication point values of the correct responses. The user is authenticated as being associated with the user account in response to determining that the confidence score meets the minimum confidence threshold.

  • Patent number: 10521984
    Abstract: Techniques described and suggested in the present document include access-card systems and methods that are resistant to attack. In certain implementations, a card reader transmits a challenge message to an access card. When the access card receives the challenge message, the access card validates the challenge message, and then generates a response message based at least in part on the information contained in the challenge message. A security server validates the response message, and when the security server determines that the response is secure, valid, and from an authorized access card, the security server grants access to a physical space. In some implementations, the challenge and response messages are digitally signed using a cryptographic key. Additional implementations include various tests that, when performed on the challenge and/or response messages detect and defeat many attempts to compromise the access-card system.

  • Patent number: 10484372
    Abstract: Secure interactions between a client device executing an application and a remote server associated with the application are enabled without credentials such as passwords. The application may acquire an encryption key pair, store a first key of the pair on the client device, and secure access to it by associated biometric data. The second key of the pair is stored on the remote server in association with the user's account. Responsive to a request on the application for an action that requires authentication with the remote server, the user must input biometric data which, only if verified, enables access to use the first key. The first key is then used to encrypt authentication data for submission to the remote server. The server accesses the public key and uses it to decrypt the data and verify the source of the request. If verified, the server then authorizes the requested action.
