APPARATUS FOR PROCESSING AN IMAGE IN A MANNER WHICH PROTECTS PRIVACY, IMAGE SECURITY SYSTEM USING SAME, AND METHOD THEREFOR

摘要

The present invention relates to an apparatus for processing an image in a manner which protects privacy, to an image security system using same, and to a method therefor. By processing only the area (particularly the facial area) in an image collected by a surveillance camera required for the protection of privacy, storing/managing the image, and restoring (protection canceling) the image to the original perceptible image at the request of the user, accidental infringement of privacy (dysfunction) can be prevented while maintaining the proper function of a monitoring system. To this end, the image security system using privacy protection according to the present invention is characterized in that it comprises: an image-collecting means which collects and encrypts images for specific security objects; and an image-monitoring/controlling means which decrypts encrypted images received from the image-collecting means, detects a security object area in the decrypted collection image, and applies a privacy protection algorithm thereto.
