Therefore, various image protection techniques can be integrated into JPSEC codestream to protect the confidentiality and integrity of JPEG 2000 images. JPSEC decoder can combine with various tools to decode the input images. These tools can be broadly divided into three categories: normative tools, registration authority (RA) registered tools, and private tools. Among them, the JPSEC RA registered tools can be defined by users and referenced by JPSEC applications after the processing of registration. The JPSEC applications without registered tools (called the network-based JPSEC applications in this thesis) will connect to specific file servers to download registered tools at the run time. Compared with those with registered tools, the size of the network-based JPSEC applications is relatively small. Due to the fact that there will be newly registered tools appeared in the RA, the network-based JPSEC applications are more flexible for practical applications. However, the JPSEC standard does not define how a JPSEC application can work in the Internet environment. This paper proposes a framework for operation of network-based JPSEC applications. Moreover, this study also designed and implemented a network-based JPSEC application to show the feasibility of the proposed framework, its operational framework is divided into three parts: JPSEC RA, enterprise file servers,　and　a　network-based　JPSEC　application. Experimental results show that the enterprise file servers can download the JPSEC tools reference list by connecting to the JPSEC RA file server to know the latest RA registered tools. Moreover, the network-based JPSEC application can connect to the enterprise file server to download the registered tool, decode JPSEC codestream, and perform security services. Therefore, the proposed framework is practical and suitable for JPEG 2000 image protections.
