Distributed content verification and indexing
Abstract:
A method of verifying content, for example webpage content, including receiving, at an indexing system (100), a first copy (240) of a document (220) from a hosting server (210), then processing the first copy (240) to obtain first indicating data including one or more properties of the first copy (240). Also obtaining second indicating data, the second indicating data obtained by processing a second copy (255) of the document (220) from the hosting server (210), the second copy (255) received by a client terminal (250), the second indicating data including one or more properties of the second copy (255). Then the first indicating data and the second indicating data can be compared, and the first copy (240) of the document (220) received by the indexing system (100) can be determined to be verified or not verified based on a comparison between the first indicating data and the second indicating data.
