Provided are an apparatus and method for providing security for an image signal in a base station or a terminal by detecting face information from the image signal. The apparatus includes a signal receiving unit receiving an image signal transmitted from a terminal, a location discriminating unit detecting a calling location of the terminal and checking if the calling location falls within a security region, and a controller transmitting the image signal when the calling location does not fall within the security region, or when the calling location falls within the security region and the image signal contains face information. Accordingly, it is possible to prevent unauthorized transmission of images without additional big burden of security equipment or an invasion of individual rights of using image communication.
