摘要： A plurality of data items are distributed across a plurality of computers, some of which may form a peer-to-peer network. A first computer receives a request for a data item from a requesting computer. The request includes a True Name of the data item. The first computer causes the requesting computer to obtain the data item from a second computer, distinct from the first computer. The first computer may not have a copy of the requested data item. The first computer may know the location of the data item. The first computer may forward the request for the data item to at least one other computer.

摘要： Access to and delivery of licensed content is controlled using content names that were determined based on the content. A name for a data item is obtained, the name having been determined based at least in part on the data which comprise the contents of the data item. Access to the data item is authorized based at least in part on the name. Once authorized, access may be granted from more than one computer. The name may have been determined using a hash or message digest function such as MD4, MD5 or SHA. The data item may comprise a file, a portion of a file, a page in memory, a digital message, a digital image, a video signal or an audio signal.

摘要： In a data processing system, a method includes deleting a particular copy of a data item when at least one other copy of the data item is available. The presence of another copy of the data item is determined, at least in part, based on an identifier for the data item, the identifier having been computed using all of the data in the data item and only the data in the data item, wherein two identical data items in the data processing system will have identical identifiers. The particular copy of the data item may be deleted if another copy of the data is determined to be present on another processor in the system or on the same processor. The identifier of the data item is computed using a function such as a message digest or hash function which may be: MD4, MD5, or SHA.
摘要翻译：在数据处理系统中，一种方法包括当数据项的至少一个其他副本可用时删除数据项的特定副本。至少部分地基于数据项的标识符来确定数据项的另一副本的存在，该标识符是使用数据项中的所有数据并且仅数据项中的数据计算的，其中，数据处理系统中的两个相同的数据项将具有相同的标识符。如果确定数据的另一副本存在于系统中的另一个处理器上或同一个处理器上，则数据项的特定副本可能会被删除。使用诸如消息摘要或散列函数的功能来计算数据项的标识符，其可以是：MD4，MD5或SHA。
