摘要

A method and apparatus for detecting a multimedia content change, and a resource propagation system. The method comprises: when importing a resource address of multimedia content, acquiring original feature information of the multimedia content; receiving first feature information of the multimedia content from a client; determining, according to the first feature information and corresponding original feature information of the multimedia content, whether the resource address of the multimedia content is abnormal; and detecting whether multimedia content at an abnormal resource address is changed. It is firstly determined whether a resource address corresponding to multimedia content is abnormal, and if the resource address is abnormal, then it is determined whether the multimedia content corresponding to the resource address is changed, thereby preventing repeated checking of a large number of normal resource addresses, improving the detection efficiency, and reducing the detection cost.
