Abstract

The increased popularity of multimedia applications places a great demand on efficient data storage and transmission techniques. Some methods have been proposed to combine compression and encryption together to reduce the overall processing time, but they are either insecure or intensive computationally. specially, they are unsuitable to wireless communication of mobile device. We propose a novel solution called partial encryption, We introduce quadtree and zerotree wavelet image compression in this paper, it reduces computation for date transmission in mobile device, and does not reduce the compression rate. In conclusion, the proposed partial encryption schemes are fast, secure, and do not reduce the compression performance of underlying compression algorithm.

멀티미디어의 응용이 날로 빈번해지면서 유효한 데이터에 대한 저장과 전송의 기술에 아주 큰 수요가 나타났다. 많은 압축과 암호화를 결합한 방법들이 제기되어 왔지만 그들은 안전하지 못하거나 계산의 양이 너무 큰 단점이 있고 특히 모바일 기기에서의 무선통신에는 더욱더 부적합할 수밖에 없다. 본 논문에서는 새로운 해결책인 선택적 암호화를 제안한다. 본 논문에서는 quadtree와 zerotree에 기반 한 웨이블릿 압축 기법을 도입하여 압축된 데이터의 일부만을 암호화 하는 방법을 제안하였는데, 압축비율에 영향을 주지 않으면서 계산의 양을 줄임으로서 모바일 장치에서의 데이터 전송을 위하여 시간을 감소시키는 효과를 얻었다. 결론적으로 제안한 선택적 암호화 기법은 속도가 빠르고 안전하며 압축 성능을 감소시키지 않은 방법이라고 할 수 있다.
