Xiao Steganography

Thumbnail steganography creates a thumbnail from a source image and stores data in it by altering it's color channels. To decipher the data, a new thumbnail is made from the original image and the differences between the pixels are calculated.

JHide is simple steganography tool aimed to demonstrate basic steganography techniques.

Steganography Studio software is a tool to learn, use and analyze key steganographic algorithms. It implements several algorithms highly configurable with a variety of filters. Also implements the best image analysis algorithms for the detection of hidden information. This software is...

Stego PNG is a steganography program which allows you to encrypt and hide a data file in a PNG or BMP image file so that the addition of the data to the container file will not noticeably change the appearance of the image. If the file which has been hidden is deleted then there is no indication...

Least Significant Bit steganography. An image is nothing more than strings and strings of bytes, each byte representing a different color. The last few bits in a color byte, however, do not hold as much significance as the first few. This is to say that two bytes that only differ in the last few...
