การสร้างระบบเพื่อใช้ลายเซ็นดิจิตอลในการลงนามร่วมกัน / วิชัย ทศมาศวรกุล = System development for multi signatory using digital signatures / Wichai Tossamartvorakul
Paper documents are still being used instead of electronic documents. This is because computer cannot replace paper document in its entirety especially the document that needs signatory, i.e. co-sinatory, hierarchical signatory. This thesis focuses on studying and designing electronic document structure that supports co-signatory. The scope of the thesis also includes document authentication. The requirements for various types of signatory document are used as the base line for electronic document structure designing. XML is used in the design of document structure. The thesis includes the development of a prototype to verify the designed document. Suggestion for improvement is provided so that the improvement can be done in the future. The document designed in this thesis supports the requirement in co-signatory, document security and document versioning. However, there is a room for improvement in data encryption and protecting alteration of XML document. So that document structure can be maintained.
