Text Hiding Under Image Using LSB Method

In most defense and research organization, they need to send and receive important textual information related to weapon designs, maps, and satellite details. If this textual information is sent normally, hackers can intercept it, and the imported information can be leaked. To prevent this, data can be hidden under an image. This process involves a plain text and an image file. We will use a cover image file and the message, and then taken into consideration the cover image pixels. In that image, we will embed each bit of secret text until the last bit of secret text is hidden under the image. Then we can send this image file to the client, who can use reverse process to retrieve the original text from the image. There are many techniques and algorithms in cyber security to hide data, and each technique has its own importance. The technique used in this study is Least Significant Bit (LSB).
