Abstract: A radio frequency (RF) beacon deployed in an indoor or outdoor environment broadcasts an RF signal that can be received by a client device operating in the environment. Based on information provided by the beacon and client device sensor data, content (e.g., a software application) locally relevant to the environment is recommended to a user of the client device. The recommended content can be manually or automatically downloaded and installed on the client device so that it can be used in the environment. In some implementations, sensor data is used to indicate whether the user is interested in receiving the recommendation and is capable of receiving the recommendation.

Abstract: Systems, methods, and apparatus, including computer program products, for security are provided. In some implementations, a method is provided. The method includes receiving a request to access a secured feature and retrieving one or more media objects associated with a particular user. The method also includes presenting the media object to the user in a page presented to the user, including presenting a request for user authentication to access the secured feature.
