ACKNOWLEDGEMENTS

The progress of any project is due to the relentless effort of many who take an interest in

working together and thus helps it to grow richer. It gives us an immense pleasure to present a

written testimony of our knowledge & to express our gratitude towards the people who were a

part of this project in numerous ways, people who have given an unending support right from the

stage the idea .

We sincerely acknowledge that progress of project we have made, would not have been

possible without sincere co-operation of the staff members. We express our sincere thanks to our

project guide, Prof. S. K. Moon for sparing his valuable time and expert guidance that he gave

us.

We are sincerely thankful to the Principal of PICT, Pune and Head of Electronics and

Telecommunication department Prof. Dr. Y. Ravinder and our project coordinator Prof. R.C.

Jaiswal who have provided us this opportunity to create and learn something new.

We also thank everybody, who directly or indirectly helped us to complete our

project.

ABSTRACT

Security in transmission and storage of digital images has it is importance in today’s

image communication and confidential video conferencing. Due to the increase use of images in

industrial process, it is essential to protect the confidential image data from unauthorized access.

Image and video encryption have application in various fields including internet communication,

multimedia system, medical imaging, Tele-medicine and military communication.

Steganography which literally means covered writing is defined as hiding the secret

message within a cover-medium in such a way that others cannot discern the presence of the

hidden message. In our project we are taking video as an embedding media. We are extracting

frames from video and taking one frame for hiding data. We are using ADAPTIVE EMD

algorithm for hiding message.

At the receiver side receiver’s thumb impression is used for authentication , if that

matches then that authorized user can be able to extract the data . The AdEMD approaches are

the anti-forensics Steganography system with the satisfactions of flexibility, adaptability,

capacity and imperceptibility.
