| 摘要 |
The present invention relates to a system for providing information through fingerprinting comprising: a fingerprint indexing unit which builds a database to extract the feature points of broadcast data and use the extracted feature points for the search; a fingerprint web server which receives a program recognition request from a client device, transmits the received program recognition request to a fingerprint matching unit, receives a search result associated with the program recognition request from the fingerprint matching unit, and transmits the received search result to the client device; and the fingerprint matching unit which performs the search by using the fingerprint indexing unit based on the program recognition request, extracts the search result, and transmits the extracted search result to the fingerprint web server.
