Secure Printing of Confidential Documents for Nomadic Users

In an economic environment more global each day, a high percent of the employees in a company spend the most part of their work time outside their offices or even outside their countries. Advances in portable devices design and arrival of communication networks capable to transmitting such data allow these nomadic employees to fulfil their tasks with the only help of a mobile phone or a PDA. However, these devices show lacks when accessing large size files, which sometimes can be needed when it is to present a report or formalize a contract at a client's head office. This problem worsens if the document contains confidential data and it cannot be hosted in an accessible server in the company nor can be sent by fax without putting its security at risk. In this paper we present a system which allows nomadic employees, using a light portable device and a secure communication channel with their company, after a search of the required document and its finding through short metadata, appropriate for being shown in the screen of this kind of devices, such as title, date and document relevant phrases, being able to request remote printing and ciphered reception with one-time key, through an open channel and for a wide range of multifunction printers supporting J2ME, avoiding the risk for the above-mentioned document to get lost.
