A multi-purpose appliance for providing a wide variety of functions, e.g., home management, device management and synchronization, archiving and distributing electronic copies of photos and/or film images and/or other services such as video conferencing is described. In various embodiments data is stored in a digital vault. The owner of stored content can set access rules and/or grant access to other individuals in a group, e.g., a family group. Content can be and sometimes is organized into categories with each category corresponding to a different type of information, e.g., medical information, personal information, calendar information, legal records family photos, etc. An owner of content can specify their relationships to another individual, e.g., another family member and have access and ownership rules apply based on the relationship to the owner of the content and/or specific user specified rules. Content is automatically added to the digital store, e.g., in response to the content being scanned or entered electronically by the owner. In response to detecting a life event, e.g., based on information in a scanned document, ownership and/or access rights to content are automatically updated to reflect the effect of the detected life event. For example a marriage may result in an automatic change to joint ownership status and/or a death may result in a change of ownership while a child leaving a house and moving to an apartment may result in an automatic restriction from obtaining access to some household financial information while the child is still allowed to access family photos.

Controlling access to nodes in a relational graph at query time by using an approximate membership query (AMQ) filter and ordered queries based on historic grants or denials of access according to security context enables a more efficient querying of the relational graph while preserving access controls. Security contexts that grant or deny access to a node are stored in an associated AMQ filter and are queried according to the subject's security context in an order based on the frequency at which the security contexts have previously granted or denied access to nodes in the relational graph.

This disclosure relates to managing a feature point map. The managing can include adding feature points to the feature point map using feature points captured by multiple devices and/or by a single device at different times. The resulting feature point map may be referred to as a global feature point map, storing feature points from multiple feature point maps. The global feature point map may be stored in a global feature point database accessible by a server so that the server may provide the global feature point map to devices requesting feature point maps for particular locations. In such examples, the global feature point map may allow a user to localize in locations without having to scan for feature points in the locations. In this manner, the user can localize in locations in which the user has never previously visited.
