Diagrams in UML can be broadly classified as: Structural Diagrams – Capture static aspects or structure of a system. Structural Diagrams include: Component Diagrams, Object Diagrams, Class Diagrams and Deployment Diagrams. Behavior Diagrams – Capture dynamic aspects or behavior of the system.

What are the different methods to implement steganography?

These methods are i) Format Based Method; ii) Random and Statistical Method; iii) Linguistics Method. iii. Image Steganography: Hiding the data by taking the cover object as image is referred as image steganography. In image steganography pixel intensities are used to hide the data.

What is steganography and its techniques?

Steganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination. The use of steganography can be combined with encryption as an extra step for hiding or protecting data.

What is steganography in image processing?

Image steganography refers to hiding information i.e. text, images or audio files in another image or video files.
