摘要： Embodiments adjust device error radiuses associated with inferred device positions produced by positioning systems. Inferred beacon positions and associated beacon radiuses are accessed for beacons in a beacon fingerprint from an observing computing device. The beacon radiuses are associated with a pre-defined confidence level (e.g., an in-circle percentage). A Kalman filter is applied to at least one of the beacons using the inferred beacon positions and the beacon radiuses associated therewith to infer a device position for the computing device and to compute a device error radius for the inferred device position. The computed device error radius is adjusted as a function of the quantity of beacons input to the Kalman filter to achieve the pre-defined confidence level.

摘要： Embodiments infer position information using captured content items. A computing device such as a mobile computing or a cloud service analyzes one or more content items to generate information describing the content items. For content items that include photographs, for example, the photographs are processed to identify faces, objects, places, text, etc. The generated information is compared to reference content items (e.g., image comparison), user data (e.g., calendar data, contact information, etc.), and/or public data (e.g., address information, event information, etc.) to identify at least one match. Location information associated with the matched reference content items, user data, and/or public data is obtained. A position is determined for the content items based on the location information obtained from the matched reference content item, user data, and/or public data. In some embodiments, the obtained location information is used to refine a position determined using a beacon-based positioning service.

摘要： This document describes policies for digital rights management that enable distribution of full-function versions of applications that, while fully functional, have functions limited by an associated policy. A policy may be replaced or updated, thereby enabling use of previously limited functions without distribution of another version of the application.

摘要： A content license associated with unencrypted digital content is generated, the content license including both an identifier of the unencrypted digital content and a content policy. At a user device, a determination is made as to whether the content license corresponds to particular unencrypted digital content. Use of the particular unencrypted digital content by the computing device is permitted in accordance with the content policy if the content license corresponds to the particular unencrypted digital content. However, use of the particular unencrypted digital content by the computing device based on the content license is prohibited if the content license does not correspond to the particular unencrypted digital content.

摘要： A digital rights management license provides access to a decryption key that can be used to decrypt an encrypted digital content item. The digital rights management license also includes a policy that defines circumstances in which the decryption key is allowed to decrypt encrypted content data for the purpose of creating a persistently-unencrypted version of the content data.
