System and method for providing content-related information based on digital watermark and fingerprint
In a method for providing content-related information based on a digital watermark and fingerprint, the method includes: receiving a request for content-related information from a client terminal; using a watermark and a fingerprint of content to retrieve the requested content-related information from a database; and transmitting the retrieved content-related information to the client terminal.
1. A method for providing content-related information based on a digital watermark and fingerprint, the method comprising:
receiving a request for content-related information from a client terminal;
using a watermark and a fingerprint of content to retrieve the requested content-related information from a database; and
transmitting the retrieved content-related information to the client terminal,
wherein the receiving of the request comprises receiving watermark information and fingerprint information of the content from the client terminal,
wherein the watermark information received from the client terminal is information in which the watermark has been decoded,
wherein the transmitting comprises integrating content-related information retrieved by using the watermark information with content-related information retrieved by using the fingerprint information, and
wherein the integrating comprises classifying, into categories, the content-related information retrieved by using the watermark information and the content-related information retrieved by using the fingerprint information, to integrate the classified information by each category.
2. The method of claim 1 , further comprising:
generating a watermark for content to insert the generated watermark into the content;
storing information on the generated watermark and content-related information associated with the information on the generated watermark in the database; and
extracting a fingerprint from the content; and storing information on the extracted fingerprint and content-related information associated with the information on the extracted fingerprint in the database.
3. A system for providing content-related information based on a digital watermark and fingerprint, the system comprising:
a database; and
a server controller configured to retrieve content-related information from a database by using content watermark information received from a client terminal, and to retrieve content-related information from a database by using content fingerprint information received from the client terminal, so as to provide the client terminal with the retrieved content-related information associated with the watermark information and the retrieved content-related information associated with the fingerprint information,
wherein the content watermark information received from the client terminal is information in which the watermark has been decoded,
wherein the server controller integrates the content-related information associated with the retrieved watermark information with the content-related information associated with the retrieved fingerprint information, to provide the integrated information to the client terminal, and
wherein the server controller classifies, into categories, the content-related information associated with the retrieved watermark information and the content-related information associated with the retrieved fingerprint information, to integrate the classified information by each category.
