Modern printers have a provision to receive print jobs from remote client devices over network and keep them as stored jobs.
At the time of sending a print job, user (at client device) has a choice to associate a PIN with the job and have it stored in
encrypted format on the printer. Even though the combination of the two seem good enough to secure user’s print data, but
this safety relies totally on the confidentiality of the PIN – once the PIN has been leaked, the data safety is compromised.
In today’s world when computing machines are capable of strong brute force attacks, the PIN alone cannot be considered
This paper proposes a solution to the problem by bringing in additional security of keeping the print ready data with the user
instead of sending it to the printer for safekeeping.
