Question

What approach would you take to transmit hidden data, in this case several sensitive Excel documents, from your work computer to an outside person? WHY?

Answer 1

Approach to transmit hidden data from computer to the other:

Steganography approach:   If you need to transmit data from one person to another or simply hide the very existence of that data on your disk, steganography in combination with encryption is a good attempt.

companies need to aware of this problem as it poses a serious data leakage . The problem is that many companies don’t deploy countermeasures to steganography because they’re not aware of the problem.

The word steganography itself originated in Greece and means “covered writing”.In the olden daya during important historic events Steganography often used to share personal secrets , plan covert oprations and some political information.

Why Steganography ?

Todays Steganography (digital) works by adding secrete bits in files such as photos or audiofiles with secret data.The fact is that it is hard to break the code and it is not widely used everywhere.In excel Steganography follows Text rotation technique.

It is implemented by slightly rotating the angle of the text inside the cell to reduce the visible detection of the embedded information. Measuring the text angle of the cells retrieves the secret information.

This is the importance of Steganography in excel, image files and audio files etc.
