A user can share digital content with another user or device using dynamically-generated barcodes. A user might request to share an electronic book ('e-book'), stored on a first device, with another user having a second device. The first device can generate a barcode that includes not only information about the identity of the e-book, but also information about the user or the first device, which can help to determine rights and/or access restrictions for the content. The second device can capture an image of the barcode generated on a display of the first device, and use information extracted from that image to attempt to obtain a copy of the e-book. Other types of barcodes can be generated based at least in part upon the context, such as where a user is attempting to locate a physical copy of a type of digital content in a retail location.

Dynamic barcode generation for content location

Techniques for facilitating a shape-based search of content items are disclosed. In some situations, the techniques include receiving a request for search of content that includes an image of an item and a glyph input by the user on the image that indicates a shape of the first item, extracting features associated with the item from an area of the image on which the glyph is input; identifying a shape category of the first item based at least in part on the indicated shape of the glyph; and conducting a search for items having features that match the extracted features of the first item, the search being conducted among a plurality of items associated with the identified shape category. The retrieved search results may be returned to a user.

Techniques for shape-based search of content

Disclosed herein are techniques, including systems and methods, for enabling a lending user to lend an application to a borrowing user. The borrowing user may use the application for a trial period, and, once the trial period lapses, the borrowing user may be given an opportunity to purchase the application. If the borrowing user purchases the application, then the lending user may be credited with a commission. According to some embodiments, in addition to or instead of lending the application, the lending user may lend or sell a status/stake in the application to the borrowing user. For example, if the application is a game, the status/stake may unlock certain levels or features of the game.
