Abstract: Disclosed is a system of managing documents based on the calendar of a user. When the user has a scheduled first event, one or more documents associated with a second occurrence of an event related to the first event can be identified and associated with the first event. In this way, a user may easily access documents related to the first event. The documents can be, for example, documents accessed during the second event or documents identified by the user with the second event. The events can be part of a recurring series of events. The events and their associated documents can be displayed in a folder format.

Abstract: A method for enabling a new member of a social network to tag photos of the new member is described, where the photos have been previously uploaded by existing members before the new member joined the social network. For example, a system can obtain a reference image (e.g., a profile picture) of the new member. The system compares the reference image to stored images in the social network using facial recognition technology and generates a list of stored images in which the new member may be pictured. The system enables the new member to take one or more predefined actions with regard to each image in the list. For example, the predefined actions may include tagging an image in which the new member is pictured, or sending a notification to the owner of an image in the list.

Abstract: A system and method are disclosed that may allow a hybrid application to support persistent login, multilogin, and push notifications. User credentials may be received and utilized to obtain an access token and a refresh token. The refresh token may be stored to persistent storage and the access token may be used to obtain a browser authentication cookie from an authentication server. The web application portion of a hybrid application may be authenticated using the browser authentication cookie.
