Steganography in Mobile Phones on Multimedia Data

Abstract

Mobile camera was developed so that people do not have to carry any separate gadgets with them all the time, since it is integrated with their mobile phones; it helps in capturing images whenever and wherever wanted. But this mobile camera is also used for some wicked purposes i.e. nude photography followed by harassment to the individual. Hence there is an utmost need to prevent such type of happenings. We have tried to developed a module which will run when the image is saved in the memory or the file system of the mobile phone. It uses steganography to hide the IMEI, model number of the phone and the date on which the photograph is taken. When this image is forwarded via Bluetooth, the same module will get executed and the IMEI, model number and date on which image it is forwarded will be stored in the image. Objective of such an approach is to capture the original culprit or the ultimate source who captured the images or videos by backtracking and also the ones who helped in forwarding of such images and prevent such misuse of camera based mobile phones.
