摘要： Provided a secure pattern recognition method. The method includes: receiving data and generating a probe by converting the received data into a template for pattern recognition; accessing a gallery that is a template registered and stored in advance; determining a region to which the probe belongs and obtaining the center point of the region; obtaining a hash value of the center point and coordinate of the probe; and determining whether or not the hash value of the center point and a hash value stored in the gallery are equal and determining whether or not the probe and the gallery are classified into the same class by calculating whether or not the coordinate of the probe is inside a decision boundary configured with thresholds on the basis of the coordinates of the center point.

摘要： A method and apparatus for extracting a face feature to construct a face search system having a high recognition rate are provided. The method includes calculating an average image of each of a plurality of candidates having one or more face images to which different weights are given according to an order in which the face images are acquired and calculating a total average image of all face images of the plurality of candidates, calculating a between-class scatter matrix based on a difference between each candidate's average image and the total average image and a within-class scatter matrix based on a difference between each candidate's average image and each candidate's predetermined face image of the one or more face images, and generating a base vector that maximizes a criterion defined by a ratio between the between-class scatter matrix and the within-class scatter matrix.

摘要： A forged face detecting method includes: acquiring a photorealistic image and an infrared image of a subject on which line beams are projected; extracting face features from the infrared image based on characteristics of a pattern of the line beams projected on the acquired infrared image; and detecting whether or not the infrared image is a forged face based on the extracted face features. Said detecting whether or not the infrared image is a forged face includes: checking whether the extracted face features falls within a preset permission range of face features; determining the infrared image to have the forged face if the extracted face features fall out of the range to acquire an infrared image of the subject again; and determining the infrared image to have a non-forged face if the extracted face features falls within the range to perform face recognition for the photorealistic image.

摘要： A method for detecting a forged face using an infrared image includes: acquiring an infrared image and a photorealistic image captured by one or two cameras; extracting a face region from the photorealistic image; determining, based on analysis of quality characteristics of the infrared image, whether a current face is a forged face or not; and performing face recognition on the extracted face region if it is determined that the current face is a non-forged face. The method further includes capturing an infrared image and a photorealistic image again through the camera without performing face recognition if it is determined that the current face is a forged face.

摘要： A digital distribution management system and a contents distribution management method using the same are provided. The system is formed of a contents-user, a broker, a contents-owner, and a contents distributor. The broker receives a contents use fee from the contents-user, transmits a contract document for contents use to the contents-user, pays a loyalty to a contents-owner, pays a distribution fee to the contents distributor, and makes a contract for contents use. The contents-owner transmits use rights, i.e., Service Release (SR) information on corresponding contents of a proper contents-user making a contents use contract to the contents distributor and receives a corresponding loyalty through a broker. The contents distributor receives the SR information from the contents-owner, transmits the contents and a license on the contents information so that the proper contents-user can use the corresponding contents, and receives a corresponding distribution fee through the broker.
