Explanation

Steganography is the practice of concealing secret data within an ordinary, non-secret carrier file so that the very existence of the hidden data is disguised. In this case, hiding encrypted images inside other image files is a textbook example of steganography. It differs from encryption alone (which only hides the content, not the existence of the data) and from steganalysis (which is the detection/analysis of steganography, not the act of hiding). Typography refers to font/text design, and 'picture encoding' is not a recognized forensic term. Steganography is commonly detected using specialized forensic tools that analyze statistical anomalies in file data.
