Visually Sealed and Digitally Signed Documents
Liu, Vicky, Caelli, William J., Foo, Ernest, & Russell, Selwyn V. (2004) Visually Sealed and Digitally Signed Documents. In 27th Australasian Computer Science Conference, 19 - 23 January 2004, The University of Otago, Dunedin, New Zealand.
One of the primary flaws with current digital signature technology is that a digital signature does not "feel" or resemble a traditional seal or personal signature to the human observer; lacking a sense of visualisation and changing each time it is applied. This paper reviews the historical value of seals in Eastern and Western cultures to provide a basis to enhance global acceptability of existing digital signatures. The functionality of traditional seals is investigated in broad terms, encompassing newly established applications to accommodate digital signature technology, and traditional seal principles. Traditional seal certificates are employed to prevent the fraudulent use of the seal and serve to bind a particular identity with a particular seal in some Eastern countries, for instance, Taiwan, Japan and Korea. This usage is analogous to the purpose of current digital certificates. This proposal develops the concept of integrating a seal certificate into an overall digital certificate. Verification of a document by visualisation is done by affixing a visual seal within a document and then digitally signing the document. Incorporating the seal images into digital certificates ensures the integrity of the seal images applied to digital signatures. This paper defines new private extensions to the X.509 v3 certificate structure and explains the new digital signing and verifying process. The purpose of this proposed solution is to fulfil the cultural gap between traditional seals and digital signatures through the integration of culturally relevant built-in features for increasing the acceptability of digital signatures in global e-commerce, while maintaining the security features of current digital signature schemes.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
