Abstract
One embodiment of the present invention provides a system that facilitates uploading content from a client to a server. Upon receiving content, the client divides the content into smaller data-blocks of a predetermined size. Once the content has been divided, the client computes a codeword for each data-bock. Next, the client computes a composite codeword for the set of codewords by computing a function of the set of codewords. The client also computes a content identifier for the content to differentiate the content from other content. Once this is done, the client sends the composite codeword and the content identifier to the server, and receives a response from the server indicating whether or not the content is present on the server. If the content is not present on the server, the client sends the content to the server.
