What are the different types of steganography?
Depending on the nature of the cover object(actual object in which secret data is embedded), steganography can be divided into five types:
- Text Steganography.
- Image Steganography.
- Video Steganography.
- Audio Steganography.
- Network Steganography.
What is LSB steganography?
LSB-Steganography is a steganography technique in which we hide messages inside an image by replacing Least significant bit of image with the bits of message to be hidden.
What is steganography state the types of steganography and explain them?
Steganography is a means of concealing secret information within (or even on top of) an otherwise mundane, non-secret document or other media to avoid detection. It comes from the Greek words steganos, which means “covered” or “hidden,” and graph, which means “to write.” Hence, “hidden writing.”
How are UML diagrams classified?
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 are the types of UML models?

What are static diagrams in UML?
Static diagrams describe the state of a system from a variety of perspectives. A static diagram describes what a piece of the system is. A dynamic diagram describes what a portion of the system is doing.
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. The current project aims to use steganography for an image with another image using spatial domain technique. This hidden information can be retrieved only through proper decoding technique.
