This document describes techniques () and apparatuses () for implementing sensor-based near-field communication (NFC) authentication. These techniques () and apparatuses () enable a computing device () to detect, in a low-power state, environmental variances indicating proximity with an NFC-enabled device () with which to authenticate. In some embodiments, various components of a computing device () in a sleep state are activated to process environmental variance(s), perform authentication operations, and/or an indicate initiation of authentication operations to a user.

Sensor-based near-field communication authentication

A client device presents content received from various content sources to a user. Different portions of the client device's memory are allocated for storing content from different content sources. The client device determines a quality score for a content source based on usability of content received from the content source. Based on the quality score for a content source, the client device allocates a portion of its memory for content from the content source. Additionally, if content from a content source is larger than an amount of memory allocated for the content source, the client device stores a portion of the content and requests storage of an additional portion of the content by an additional client device. When the client device has sufficient memory to store the content, the additional portion is retrieved from the additional client device and combined with the portion of the content.

Allocation of client device memory for content from content sources

This document describes techniques () and apparatuses () for implementing low-power near-field communication (NFC) authentication. These techniques () and apparatuses () enable a computing device () to detect, in a low-power state, an NFC-enabled device () with which to authenticate via NFC. In some embodiments, various components of a computing device () in a sleep state are activated to perform authentication and/or an indication is provided to a user indicating an initiation of the authentication.

Low-power near-field communication authentication

In embodiments of device to device content upgrades, a computing device includes a peer sharing manager that shares content and upgrades to content with peer devices. The computing device downloads content and upgrades from sources on the Internet, and shares the content and upgrades with peer devices that lack an Internet connection. A lowest supported version of the content can be shared from the computing device to one of the peer devices. The lowest supported version of the content determines capabilities of the peer device and establishes a peer-to-peer communication link with the computing device. The peer device reports the capability information to the computing device and, if the computing device determines that the peer device is capable of supporting an upgraded version of the content, the computing device communicates the upgraded version of the content to the peer device.
