How to Hide Data in Image, Audio & Video Files

Ever wondered how to hide secret messages in images, audio and video? Well, in this position, I will guide you through a process called steganography, which helps, it is possible to hide secret information in your image files, the songs or other files of your choice. At the end of this position, you can download the tools and start stegnographic hide your data.
What is steganography?Steganography is a way to hide the data secret messages hidden in computer files, including images, audio, video and even executable files, so no one but the sender and the receiver will suspect information at this stealth. Steganography can also include the use of cryptography in which the message is first encrypted before hidden in another file. In general, the messages seem to be something like a picture, sound or video and the transfer of secret data is unexpected.
The main advantage of steganography over other methods such as encryption is that there will be suspicions, even if the files that fall into the hands of another. Unlike cryptographic messages, you stegnographic no way to draw attention to a third party for themselves. So stegnanography has upper hand for encryption, because it involves both encryption and darkness.
What are the applications of steganography;Steganography is used mainly for hiding sensitive information / data during storage or transmission. For example, you can hide a secret message in an audio file and send to others via e-mail instead of sending the message in text form. The receiver at the other end to decrypt the hidden message using the private decryption key. At worst, even if TPA gains in e-mail, you only can find is the audio, not data hiding inside. Any other use of steganography include watermarking images for reasons such as copyright protection.
Eventhough steganography has many useful applications, some may use this technique for illegal purposes, such as hiding a pornographic and other large files. The Roumors terrorists using steganography to hide and to share intelligence information and instructions are also reported. An article claiming that al Qaeda had used steganography to encode messages into images, and transported via e-mail, reported by the New York Times in October 2001.
How Steganography Tools work?Tools for the application of intelligent algorithms for integrating Stegnography carefully encrypted text or data inside other files, such as a larger image, audio, video or executable.Some tools that incorporate the encrypted data at the end of another file, so that there is enough space for storing data.
There are many tools available steganography on the Internet, but only few are able to function perfectly. I have not found any tools that worked perfectly in the data ages. However, I could develop my own tool that can work well on all file types and sizes of data. The tool is called "stego Magic". You can download from the link below.
Download Magic stegoDownload StegoMagic.zipThe zip file contains two versions of the stego Magic: A to encrypt text messages and one for encryption of binary files. StegoMagic_TXT can be used to hide text messages within other files, such as an image or audio file. StegoMagic_BIN can be used to hide a binary file to another, as an executable file in an image or an image in a video file.
Stego with Magic, there is no limit to the size and type of file you intend to hide. For example, you can hide a video size of 1 GB into an image of size 1 MB or hide an executable file in a document in Word. The tool is fairly simple to use and requires no special knowledge of the concept.
At the end of the encryption process, a secret decryption key is generated and the same is necessary for the decryption process.
Stego how to use magic?Suppose you want to hide a text message in a JPG file:
1. Load the JPG and text file (. Txt) in the same folder StegoMagic_TXT.exe
2. StegoMagic_TXT.exe Run and follow the onscreen instructions to incorporate the text of the message within the JPG image.
3. Note the secret decryption key.
Now you can send this image to friend via e-mail. To decipher the hidden message, your friend must load the file in JPG stego magic tool and use the secret decryption key.
