Abstract

Securing data during the transmission over a wire is widely popular. It is usually accomplished by encrypting the data during the transmission. However, data on a physical paper is rarely encrypted. This publication talks about the concept of encrypting data on a printed paper. This will provide comparable level of security to the data on a printed paper as it would be during the transmission over the wire.

In today's business environment, strategic business information needs to be communicated securely, to protect the interest of business and shareholders. There are many technologies for encrypting e-mail, tunneling for networks, and scrambling telephone conversations to discourage eavesdropping.

However, as business expands into investing in developing economies, high-speed internet connections and secure telephone terminals are often unavailable. Furthermore, governments and competitors in these markets may have a strong incentive to compromise the information to obtain an advantage over the investor. For example, consider the following scenarios: A businessman needs to deliver business strategy information to a partner stationed in a developing country to open a small service center. The customs are likely to delay or confiscate CDs or floppy disks entering the country through the post, making the sending of information electronically infeasible. The hotel has a FAX machine, but the businessman cannot ensure that confidential information received via FAX will not be compromised before the FAX is picked up. Alternatively, suppose that t he businessman needs to receive economic intelligence in paper form for reasons stated above, but must be able to ensure that the document cannot be photocopied with conventional equipment, to discourage unauthorized distribution .

We propose a solution to this problem, allowing...
