Abstract: A system and method for transmitting content on a peer-to-peer network. A content item a content provider and divided into a plurality of content segments. Each of the content segments is encrypted and dividing into at least one content segment stripe. Each of the content segment stripes are transmitted one of a plurality of nodes on the peer-to-peer network, wherein substantially all of the content segment stripes are transmitted to different nodes on the peer-to-peer network for retransmission substantially in parallel to a second node on the peer-to-peer network.

Abstract: In some implementations, methods and apparatus, including computer program products, facilitate microtransactions over electronic networks by providing an electronic points currency that can be purchased in bulk and used for purchasing goods and services in microtransactions. In a typical implementation, points may be purchased in bulk quantities that have a value that is large relative to the price of a single product that may be purchased in a microtransaction. A microtransaction vendor may offer products for sale at a discount by setting a first price for purchases made with a credit card and a second lower price for purchases made using points.

Abstract: Systems and techniques for marketing license rights in digital media involve providing a library of digital media for which users can purchase individual digital media licenses and hosting multiple online user-defined stores. Each online user-defined store offers a subset of the digital media in the library of digital media and is associated with a user account. A credit is allocated to a user account based on a purchase of a digital media license if the purchase is related to an online user-defined store associated with the user account.

Abstract: Systems and techniques managing license rights in digital media involve storing digital media license records associated with multiple user identities. The license records for each user identity are accessible from a remote device using a first authentication credential corresponding to the user identity. Digital media licenses are offered for purchase using second authentication credentials. A particular second authentication credential is associated with the first authentication credential corresponding to a particular user identity. A record for a digital media license purchased using the particular second authentication credential is stored in association with the particular user identity based on the association of the particular second authentication credential with the first authentication credential corresponding to the particular user identity.

Abstract: Techniques and systems for managing digital rights involve monitoring an interface of a user device for attempts to transfer files and detecting an attempt to transfer a file through the interface. When a file is identified as a copy of a protected file, a determination is made as to whether a license for the file exists. The attempted transfer of the file through the interface is selectivity allowed based on a result of the determination.

Abstract: Techniques and systems for for managing digital rights can be implemented to protect against unauthorized copying of digital content and to help ensure payment to content owners and distributors. Digital wrappers can be applied to data files to prevent access without a valid authorization. Information relating to authorizations to access data files and/or keys for accessing the data files may be stored and retrieved using data stored in a non-volatile storage area of a user device. Software on the user device can be used to recognize files and to apply digital wrappers to recognized files. In addition, the software can be used to remove digital wrappers from files in accordance with authorizations to access the files. Payments or other credits can be allocated among distributors of a data file using information associated with the digital wrappers.
