Abstract EN
The least significant bit (LSB) substitution techniques are detected by RS analysis and the traditional pixel value differencing (PVD) approaches are detected by pixel difference histogram (PDH) analysis.
The PVD steganography can escape from PDH analysis by using the edges in multiple directions.
This paper proposes a steganography technique by exploiting the edges in eight directions and also using LSB substitution to resist from both RS analysis and PDH analysis.
For every 3×3 pixel block the central pixel is embedded with 3 or 4 bits of data by modified LSB substitution technique.
Then this new value of the central pixel is utilized to calculate eight difference values with eight neighboring pixels.
These eight difference values are used to hide the data.
There are two types with regard to two different range tables.
Type 1 uses 3 bit modified LSB substitution and range table 1.
Type 2 uses 4 bit modified LSB substitution and range table 2.
Type 1 and type 2 are also known as variant 1 and variant 2, respectively.
Type 1 possesses higher PSNR and type 2 possesses higher hiding capacity.
