Introduction
Problem Definition
the Internet is a popular communication channel for messages and images transmission which need protection and authentication in different scenarios.
Two ways main ways to achieve such protection
Cryptography: making a message unreadable
Steganography: concealing a message inside another
Problem Definition
The data hiding-based steganography is used by application where parties need to exchange messages through images while preserving visual fidelity of the image.
A well-known steganography methods are
the one based on the least significant bit (LSB) technique.
Other methods enable hiding a variable length of bits in each byte according to the characteristics of the human visual system.
Problem Definition
Thermal imaging is a technique which converts an invisible radiation pattern of an object into visible images for feature extraction and analysis.
This technique was first developed for military purposes but later gained a wide application in various fields such as medicine, veterinary, security surveillance and others.
Aim
The aim of this research is:
Designing a thermal image authentication technique integrating the Integer Wavelet Transform (IWT) with a hash function.
Proposed Approach
The Proposed Method
In this method,
the thermal images were used as cover images
bits from secret data (images) were then hidden in the cover images.
This was achieved by using
the hash function and
IntegerWavelet Transform (IWT).
1, 2 and 3 bits per bytes have been hidden in both horizontal and vertical components of wavelet transform.
The Proposed Method
Results
Used Dataset
10 thermal images (.ppm) were used as cover images
They have been taken by different cameras and collected from the Internet.
These images are 512x512 pixel in dimension
The secret image that is used to be embedded in the cover images is 128128 pixel in dimension.
Used Dataset
Experimental Results
Experimental Results PSNR and IF
Experimental Results
Comparison with Related Work
Conclusion and Future Works
Hash based thermal image authentication technique using the Integer Wavelet Transform (IWT) was proposed
The performance of the proposed technique was evaluated using MSE, PSNR, and IF analysis and they have shown good performance for the proposed technique
A comparison with the most related work showed that our technique obtained a better performance
In the future, more analysis will be done to provide countermeasures to possible attacks.
