Abstract: An authentication system may receive a request signature corresponding to a user request to view secure user information on a user device and generate a server-side signature matching the request signature to authenticate the user device to receive the secure user information without authenticating the user. The request signature may include a device identifier corresponding to the device, a token code generated by the authentication system and stored by the user device, a timestamp corresponding to the transmission time of the request signature, and a version of the device identifier, the token code, and the timestamp encrypted using a signature key provided to the user device by the authentication system. The authentication system may generate the server-side signature using the timestamp and stored copies of the device identifier, the token code, and the signature key.

Abstract: A server can be configured for facilitating notifications about interaction opportunities for users using database relationships of separate types of data from different systems. The server can receive token data from an application executing on a mobile computing device. The token data can include geolocation data of the mobile computing device and identification data of the user. The server can determine a location of the mobile computing device using the geolocation data. The server can use the identification data of the user to receive interaction opportunities based on the identification data and criteria associated with the interaction opportunities. The server can use the identification data to receive interaction opportunities that are associated with locations within a pre-selected distance of the location of the mobile computing device. The server can transmit the interaction opportunities to the mobile computing device for output by the application.
