Abstract: An integrated certification system is a system for performing integrated certification on products to which genuine-product certification labels are attached. The integrated certification system includes an integrated certification management server. The integrated certification management server includes a distribution management module configured to acquire distributor identification information and a distribution number of each of the products from each distributor and match the distribution number to an identification number assigned to a corresponding distributor and a genuine-product certification module configured to receive a genuine-product certification request including user-related information and an identification number extracted from each of the genuine-product certification labels from a user terminal and perform genuine-product certification according to the received genuine-product certification request.

Abstract: A server computing device and an image search system based on contents recognition using the same are provided. The image search system includes a server computing device, and the server computing device is configured to perform an operation of receiving image search basic information including at least one among an image, a keypoint extracted from the image, and an image search condition from a user computing device; an operation of extracting a keypoint which matches with a search request keypoint obtained from the image search basic information among keypoints which are previously stored; and an operation of transmitting at least one of an image and image related information corresponding to the extracted keypoint to the user computing device.

Abstract: A device and method of extracting a keypoint, and an image matching system for analyzing an online distribution situation of contents using the same are provided. The device for extracting a keypoint which is robust to image change, includes: a keypoint extraction unit configured to extract a corner region in an image as a keypoint candidate region, and extract the keypoint from the keypoint candidate region; and a keypoint postprocessing unit configured to generate a keypoint descriptor with respect to the extracted keypoint.

Abstract: An apparatus and a method for generating a constructively multi-patterned watermark, an apparatus and a method for inserting and detecting the watermark using the same. The method includes dividing user's hidden data into plural partial data and outputs the plural partial data, performing a message-encoding of the plural partial data, modulating the plural message-encoded data into image signal format and outputting plural message signals, generating a synchronization signal for synchronizing the constructively multi-patterned watermark with a two-dimensional translation of an image, generating, plural sub-base patterns using the plurality of message signals modulated into the image signal format, and the synchronization signal, and generating a base watermark that is the constructively multi-patterned watermark, using the plural sub-base patterns.
