Steganography is the practice of hiding private or sensitive information within something that appears to be nothing out to the usual. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the internet.

For hiding secret information in images, there exists a large variety of steganography techniques some are more complex than others and all of them have respective strong and weak points. Different applications may require absolute invisibility of the secret information, while others require a large secret message to be hidden.

This project report intends to give an overview of image steganography, its uses and techniques. It also attempts to identify the requirements of a good steganography algorithm and briefly reflects on which steganographic techniques are more suitable for which applications.

Project Scope:

This project is developed for hiding information in any image file. The scope of the project is implementation of steganography tools for hiding information includes any type of information file and image files and the path where the user wants to save Image and extruded file.

Methodology:

User needs to run the application. The user has two tab options – encrypt and decrypt. If user select encrypt, application give the screen to select image file, information file and option to save the image file. If user select decrypt, application gives the screen to select only image file and ask path where user want to save the secrete file.

This project has two methods – Encrypt and Decrypt.

In encryption the secrete information is hiding in with any type of image file.

Decryption is getting the secrete information from image file.

Software used:

Front End – C# (.Net Framework 3.5)

Namespace and Base Classes used in this project are

• System.Drawing
• System.IO
