Data Diddling

Have you heard of data diddling? It is a method adopted by computer criminals.Data diddling is the changing of data before or during entry into the computer system or altering the raw data just before it is processed by a computer and then changing it back after the processing is completed. Using this technique the criminal can manipulate the output and it is not so easy to identify. But using cyber forensic tools we can trace out when the data was changed and changed it back to the original form.
