Abstract

Traditionally, the document was recorded on the papers and signed by related personnel to differentiate the responsibility. As the technology of communication is evolved quickly, it makes people connect each other by many different ways. Now, the e-document can be transferred on the network and e-signed with proper tools. However, it still needs people to stay in front of desktop to send and receive e-document. In this paper, we propose a way to send and receive the urgent e-document with cellular phone. For the sake of safety and non-repudiation, the users need to e-sign the document after receiving and before sending our e-document using the embedded wireless identity module (WIM) inside the SIM cards. The use of WIM in the SIM card to sign e-document can make the signing process more secure and reduce the possibility of argument. A prototype of this system was implemented. As can be imagined, the system will provide convenience and security for top managers to handle urgent events and e-document on the move
