Abstract

A browser emulator manager causes a browser emulator(s) to access a website. The browser emulator traces content interpretation and script execution on a browser that have occurred by access to the website. When detecting transfer, the browser emulator records, in transfer information, a transfer method, a transfer source URL, and a transfer destination URL thereof. When detecting the script execution, the browser emulator records, in the transfer information, an execution method and an execution source script thereof. A graph construction unit constructs a directed graph on the basis of the transfer information. Thereafter, a graph analysis unit specifies places of content and a script causing the transfer by tracing the directed graph.
