Hiding images in plain sight refers to concealing an image within another image or a larger context, making it difficult to detect with the naked eye. This is often done through techniques such as steganography, where the image is embedded within the pixels of another image or hidden within the data of a file. This technique can be used for various purposes, such as hiding secret messages, protecting copyrighted material, or adding an extra layer of security to digital files.

What is the LSB technique in steganography?
The least significant bit (LSB) technique is a common method used in steganography to hide information within an image or audio file. In this technique, the least significant bit of each pixel in an image or each sample in an audio file is replaced with a bit of the secret message to be hidden. Since the LSB is the least significant bit, it is thought to have minimal impact on the overall quality of the image or audio file. Therefore, the changes made by this technique are often imperceptible to the human eye or ear. This makes it a popular choice for hiding information in plain sight.
