Abstract: Methods, systems, and devices for data management are described. A client may transmit, to a server, a login request for an application. The login request may include authentication parameters associated with a user. The client may receive, from the server, an access token that supports access via a user interface to one or more services associated with the application before expiration of a time-to-live for the access token. The client may transmit, prior to expiration of the time-to-live for the access token and based on a session inactivity timeout timer being active, a refresh request for a new access token. The refresh request may include an indication of the access token. The application may receive the new access token in response to the refresh request, and the new access token supports access to the one or more services before expiration of a time-to-live for the new access token.

Abstract: Methods and systems for grouping of media based on similarities between features of media data are provided. A method of managing a plurality of images may include: identifying a threshold distance for clustering the plurality of images based on a degree of similarity between the plurality of images; extracting a plurality of feature vectors corresponding to the plurality of images; and generating at least one cluster comprising at least two images among the plurality of images, based on cosine distances between feature vectors corresponding to the at least two images being less than the threshold distance.
