본 논문에서는 SW 분할 실행을 이용한 데스크탑 가상화 환경에서 데이터 보안 방법을 제안한다. 사용자에게 분리된 가상머신을 할당하는 가상화 환경에서는 하나의 가상머신에서 실행되는 어플리케이션이 다른 가상머신에서 실행되는 어플리케이션과 고립된다는 장점이 있지만, 어플리케이션 가상화 서비스를 위한 분할 실행 기술에서는 서버에서 실행되는 어플리케이션들이 서버의 루트 권한으로 실행되므로 사용자 사이의 고립을 지원하지 않아 데이터 보안에 문제가 발생한다. 본 논문에서는 이 문제를 해결하기 위해서 서버 스토리지 필터, 뷰어 필터 및 파일 매핑 테이블을 이용한 데이터 보안 방법을 제안한다.
