Manipulation of Electronic Devices and Data in Dispensing Pumps

The sale of fuel through electronics controlled based
Dispensing units in the retail outlets are the source of
manipulation. The stake holders are customers and are directly
affected by the unauthorized manipulation by the petroleum
product selling units. The electronic devices are more prone for
changing the original encrypted data or stored data as a
program. The program stored in this device can be altered
unauthenticated by external device attached to the original
circuit’s boarders. The circuits board is build with the
microcontroller based hardware that controls the outlet pipe by
setting the control signal by the selling unit. This can be alter by
changing the pulse which are used to modulate the information
bits so that cheating the customer by alter the set control bit by
deliver less or more through the dispensing unit. This research
article focus on explore the possibilities to make the encryption
method of control bits more robust than the present simple pulse
modulation techniques.
