image stenography  source code in java pdf

The image steganography project is an application related to encryption that is used to transmit data securely by encrypting image files and decryption on the receiving side. The work procedure is explained below.

Source code of the Java steganography project

Steganography Image Java Project Work and design:
Steps to encode
In the first way, there is a total of 5 tabs, namely, encoding, decoding, Help, About us, Start.
When the user clicks on the coding tab, this form appears.
To select a file to be hidden in a BMP image, the user must click on the Open Source button.
When the user clicks on the Open Source button, a dialog box will open from which the user can select a file with any extension to hide.
After selecting a particular file, the file will open another window.
To select the BMP image in which the file should be hidden, the user must click on the Open BMP button.
For encoding, the user must provide an 8-character password that is also encoded / hidden in a BMP image.
In a text field in front of each button, the path of the particular file will be displayed.
In front of the label of the test file, you must indicate the path to store the encoded image.
For the actual processing, the user must click on the Process button.
The processing will be done as follows

The image must be 3 times larger than the original file to be hidden.
If the password does not have eight characters, it will give an error.
Steps to decode

After encoding the images that are before hiding and after hiding them, they will be displayed in two separate windows.
To decode, the user must close the window and click on the Decode tab.
To open images with a hidden file, click Open BMP button and follow the same path where the encoded image is stored. The full path will be displayed in the text box in front of the DestFile button.
The text box in front of the Original button, the name and path of the recovered file is stored.
The same password must be given by the user in the decoding code as well.
When the user clicks the Decode button, the actual decoding begins and the original file will open in separate images.
