Analysis of transform domain techniques in image Steganography
[attachment=24630]
INTRODUCTION
steganography - form of security through obscurity.
The first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia.
Advantage over cryptography - messages do not attract attention to themselves.
MOTIVATION
Disadvantages in cryptography, watermarking, fingerprinting.
Extensive use of steganography techniques in recent years.
High frequency usage of images on the internet.
Among the techniques present, transform domain are convenient.
