Abstract: A secure server is configured to host one or more secure applications. A first user device includes a camera operable to capture a first image of a first user of the first user device. The first user device receives a notification that indicates confirmation of authentication of a second user of a second user device is needed after the second user requests access to the secure server. Following receipt of the notification, the first user device captures a first image of the first user. The first image includes at least a portion of a face of the first user. Facial recognition is performed, and results of facial recognition are provided to the second user device where it is used for multi-person authentication.

Abstract: A system includes a multi-person authentication server which receives an authentication request corresponding to a request to provide a first user access to a secure server. In response to the authentication request, a challenge-response message is provided to the first user device. A push notification is also provided to a second user device. A response to the challenge-response message is received from the first user device. If the received response indicates the first user is authenticated, the first user is allowed to access the secure server. If the received response indicates the first user is not authenticated, the first user is prevented from accessing the secure server.

The first user device captures a first image of the first user. The first image includes an image of at least a portion of a face of the first user. An authentication result from facial recognition scan of the second user is received. Facial recognition is used to determine that the face of the first user is a face of an authorized user of the secure server. The first user device generates and sends a response to the challenge-response message based on results of facial recognition and the received authentication results.
