Steganography is method dealing with writing hidden messages in a specific path that only the sender and the receiver are able to decrypt. Important domains, besides classic computing, where steganography can be applied are domains using mobile and embedded devices. This project work mainly focuses on the implementation of a steganographic algorithm on embedded devices like ARM, PIC or any equivalent embedded device.The advantage of FPGA for steganography is speed, a FPGA being able to execute steganographic algorithms more Faster than other devices. The disadvantage in using an FPGA is cost, making them impossible to be used in small devices like mobile phones etc. The objective of our project work is to implement steganographic algorithms like the LSB algorithm on embedded system like using ARM, PIC or any equivalent mobile or embedded devices without significantly raising their price.The main purpose of implementing such an algorithm on a microcontroller is to bring steganography and its advantages on low and medium cost mobile and dedicated devices
