The invention provides a method, system, and computer program product to control the access, copying, and/or transfer of a digital asset by mobile, wireless devices using a digital voucher. The digital voucher references a primary content that contains all of the expression for that particular asset and a secondary content that contains information that can be distilled out as a preview. The information in the primary content can be limited to a specified duration or a specific number of viewings. The author, owner, or possessor of the digital asset specifies the terms and conditions for distribution of the digital asset. The digital voucher authorizes the mobile, wireless device to access a specified primary or secondary content that may be located elsewhere in the network. The mobile, wireless device can download a copy of portions or all of the content depending on the terms specified in the voucher.

Digital rights management in a mobile communications environment

A digital rights management (DRM) “bureau” server can be used in many different ways. In one example, a system distributes the storage of rights and/or the rights management decision making process between a DRM client and a DRM server, in order to overcome the shortcomings inherent in exclusively client-side or exclusively server-side DRM systems. In another example, a system manages rights to content on behalf of plural publishers.

The present invention utilizes an aggregator for searching, packaging and delivering content. The aggregator processes requests, searches, provides search results and acquires content. The aggregator, operating in a communications network, includes a request and results processing server, a search engine server coupled to the request and results processing server and a content acquisition server coupled to the request and results processing server. A request and results processing server receives a request for content, the search engine server searches for the content and the content acquisition program acquires content for delivery to the user. The request and results processing server includes a search request processor that receives information related to a user's search request and provides the information to a search results form builder that creates an electronic search request.

A digital content distribution and subscription system for digital data files, which provides subscriber (64) with music or video (62) for a fee.Subscribers (64) may subscribe to a predetermined number of song slots for a period of time.The subscriber (64) may select songs from various play lists, which causes encrypted digital audio files (68) for the selected music to be downloaded to the subscriber's PC.A license key (66) is downloaded to the subscriber's PC to enable the selected songs to be decoded and displayed for a predetermined time period.At the expiration of the time period, the license key (66) expires.Each subscriber's selections are tabulated for the purpose of toyality tracking and payment of a license fee to the copyright holder.The current system provides subscribers (64) with relatively high-quality digital audio files (68) and allows subscribers (64) to select from a wide range of stored digital audio files (68) on demand while not violating copyright laws.

Digital content distribution and subscription system

Peer-to-peer file sharing is increasing in popularity on the Internet, faster than any product known in history. Although file-sharing can enable massive piracy, it has many advantages for distribution of information including scalability. Alternatively, file-sharing can be sabotaged with falsified files and used to distribute viruses. To this end, a solution that maintains the scalability of file-sharing and promotes reliability is proposed. The solution involves embedding data within the file or content and using the data to identify the content, demonstrate its completeness and lack of viruses, and verify the file can be shared. The embedded data can be checked when the file is registered with the database for sharing, and before or while the file is being uploaded and/or downloaded. Ideally, the embedded data is added at the time of creation for the file. The embedded data may include a watermark and be linked to other copy management systems, such as those proposed in DVD and SDMI. Finally, the embedded data can be used to enable purchases of files that owners do not have rights to share.

Using embedded data with file sharing

Rental of the digital content occurs within an online environment including one or more user network-enabled devices and one or more server network devices connected by a communications link to the one or more user network-enabled devices. A user selects content displayed on a main website and requests download of the selected content to the user network-enabled device. To be able to access the content the user must obtain a license. The user's request for a license for specific content comprises information about a desired rental model, an expiration date for the rental model, and information that identifies the user's user network-enabled device, along with other information. A license for the content is generated which comprises the above information and also includes an encryption key for the selected movie. Media player and security technology residing on the user network-enabled device provides protection against unauthorized access to the content by ensuring that only licensed content is viewed and is accessed according to the rental model contained in the license.

Secure digital content licensing system and method

Network systems and processes for delivery of electronic content to recipient processors may be configured to facilitate the delivery of relatively large content items and/or a relatively large number of content items. In one example, a movie rental system and process delivers (downloads) movie files to customers across the Internet. System network architecture includes three or more layers of servers, including a main server supporting an interface for recipient processors to request content items, a plurality of parent servers, and a plurality of edge servers. Edge servers are distributed throughout a region in which the system provides content delivery services to recipient processors. Parent servers, spaced across the service region, support edge servers. A copy of each content item available through the service is distributed from the main server to each parent servers for storage. Parent servers distribute content to edges servers, pursuant to instructions from the main server or requests from the edge servers. The main server receives and processes requests for content items from recipient processors and directs recipient processors to edge servers for obtaining requested content items. The main server also authenticates licenses and publishes rules for the distribution of content items.
