Invisible Secrets by East-Tec (formerly NeoByte Solutions) is a Win32 steganography program that hides data in JPEG, PNG, BMP, HTML and WAV files.
Supports strong encryption (Blowfish, Twofish, RC4, AES, Cast128, GOST, Diamond 2, Sapphie II)
PNG and JPEG - the hidden data is placed in the comment field of these file image types (which is located at the beginning of the file for JPEG, at the end for PNG)
BMP and WAV - uses a 1-bit LSB method
HTML - uses spaces / tab (0/1) added at the end of the lines
In Invisible Secrets 2002 3.2, the LSBs of BMP images not used by the hidden data are all set to 1 or 0, which makes it blatantly obvious that something is hiding. This has supposedly been fixed in v4.
