Image Steganography is an application related to encryption that is used to securely transmit data by encrypting image file and decryption on the receiving side. The working procedure is explained below.

Steps for Encoding
• In the first form, there are a total of 5 tabs, ie, encode, decode, Help, About us, Home.
• When the user clicks the code tab, this form is displayed.
• To select a file to be hidden in the BMP image, the user must click the Open Source button.
• When the user clicks the Open Code button, a dialog box is opened 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 the Open BMP button.
• For coding, the user must give an 8 character password which is also encoded / hidden in the BMP image.
• In a text field in front of each button, the path of the particular file will be displayed.
• In front of the tag of the test file, you must indicate the path to store the coded image.
• For actual processing, the user must click on the Processing button.
Processing will be done as follows
1. The image must be 3 times larger than the original file to be hidden.
2. If the password is not eight characters, it will give an error.
Steps for decoding
• After encoding the images that are before hiding and after hiding, 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 hidden files, click the Open BMP button and follow the same path where the encoded image is stored. The full path will appear in the text box that is in front of the DestFile button.
• The text box in front of the Original button, the name and the 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 starts and the original file will open in separate images.
