What is steganography and how does it work?

Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video. The word steganography comes from New Latin steganographia, which combines the Greek words steganós , meaning “covered or concealed”, and -graphia meaning “writing”.

Are there any datasets available for stego images?

Yes there are some datasets that I refered in my articles. This is a database that our research team created from scratch, using purchased mobile phones and a camera app we wrote. It has stego images created from mobile stego apps that we reversed engineered to batch produce 565,000 stego images.

Is it possible to synthesise a realistic data set for steganography research?

As long as we do not have any inkling about the distribution of steganogrammes in the field, it is impossible to synthesise a realistic data set. We simple lack the information about use cases to construct a canonical benchmark. Your data set has to be tailored to your research questions and assumptions.

How many stego images can be created from mobile apps?

This is a database that our research team created from scratch, using purchased mobile phones and a camera app we wrote. It has stego images created from mobile stego apps that we reversed engineered to batch produce 565,000 stego images. I am working in developing the blind steganalysis technques for images using matlab coding .

Steganography includes the concealment of information within computer files. In digital steganography, electronic communications may include steganographic coding inside of a transport layer, such as a document file, image file, program or protocol. Media files are ideal for steganographic transmission because of their large size.

What is robustness in steganography?

Robustness and cryptography. Steganography tools aim to ensure robustness against modern forensic methods, such as statistical steganalysis. Such robustness may be achieved by a balanced mix of: a stream-based cryptography process; a data whitening process; an encoding process.

What is the root word of steganos?

The root “steganos” is Greek for “hidden” or “covered,” and the root “graph” is Greek for “to write.” Put these words together, and you’ve got something close to “hidden writing,” or “secret writing.” it to do some pretty creative things.
