A limitation in fax technology is addressed by a mechanism for improving the security methods used to send confidential documents to the intended receiver. The sender is allowed to assign some authentication code(s) and send it through other communication channels to the receiver. The faxed document would be saved in the multi-function device memory and only gets released for printing if the receiver keys in the correct authentication code. If the wrong authentication code(s) are entered by the intended receiver or someone else, the sender receives signal of unsuccessful attempts to receive the faxed document. In this case, sender can send an instruction by signal or notification to destroy the faxed document. Benefits include adding additional control to the fax workflow, through additional authentications required and the ability of the remote sender to destroy the job if someone is attempting to hack the required authentication values.

Authentication Driven Secured Reception of Facsimile Transmitted Data

In telecommunication domain, supplying data, be it highly sensitive or not, with employing proper security is one of the main challenges. When it comes to the question of employing security, it brings many scenarios of having intrusion at sender side or receiver side or in the medium through which the data are being transferred. The proposed invention deals with the possible ways of intrusion at receiver side.

Considering the present workflow of fax, one limitation has been observed where sender doesn't get to know whether there is an intruder attack at the receiver end even if the faxed data is password protected. Also when the data are sent from the sender side, then sender no longer has any authority over the sent data. The proposed invention, introduces a method to provide such added security measure to raise the assurance of the faxed data to be delivered to the intended receiver only.

Initially, instead of printing the faxed documents to be printed immediately by the built-in printer, a reasonable memory is proposed to be allocated to store the incoming fax information in a digital form before printing it. When user sends data to a receiver via fax, user will have an option to set the number (say N where N ∈ Z) of authentication to be performed at the receiver end in order to get the faxed data. For each authentication event sender may set different authentication codes which are considered to be a part of prior knowledge of the intended receiver. Upon arrival of the faxed data at the receiver side, receiver will have to provide proper key for the N number of authentications set by the sender. On receiving positive result from each successful authentication, receiver will be able to get the faxed data printed. If the faxed data is not confidential then N can be zero which means that no authentication is needed and the faxed document can be printed without any authentication key.

Instead of intended receiver if an intruder hits the authentication code and the authentication code is examined to be invalid then sender will receive a message stating the possibility that the sent data are under access of an intruder. In this scenario, sender will have an option to send an instruction to the fax residing at receiver side to destroy t...
