One web search server, for for a false proof bill search function, one its search method, an image forming device and a network security system, for for function, it is arranged to promote search sweep document data with its record media, provide scanning document data by one database of construction and scans document data from the database search with a keyword. One messenger (110) is by network and at least over an image forming device connection. Text is extracted in OCR processing of one OCR (optical character recognition) processor (120) by execution for pictorial data from pictorial data. The index file of one at least one Text Feature Extraction time of one division device (130) generation/storage, image forming device user information and a keyword. One search engine (150) searches for what index file matched at least one Text Feature Extraction time, image forming device user information, from the keyword of storage index file, search/output text map works as at least one Text Feature Extraction time to search index file, when image forming device user information and keyword are received.
