This is a client-side Javascript tool to steganographically hide images inside the lower "bits" of other images. Select either "Hide image" or "Unhide image". Play with the example images all x px to get a feel for it. Each channel red, green, blue of each pixel in an image is represented by an 8-bit value.

To hide the secret image inside the cover image, we replace the n least significant bits of the cover pixel value with the same number of most significant bits from the secret pixel value. Example, using 3 hidden bits:. Using a larger number of hidden bits results in a better quality hidden image, but makes it easier to tell that the hidden image is there.

Play with the 'hidden bits' slider to see. There is an example on Wikipedia of a cat hidden in a picture of a tree. To do the example here, use the 'Unhide image' tool to select the 'Wikipedia tree' example, and set hidden bits to 2.

All of the computation is performed in your browser in Javascript. Be careful with larger images as it can be quite slow. Once you've hidden your secret image inside a cover image, send the output image to your accomplice.

Your accomplice then uses the 'Unhide image' tool to recover the secret image. You can learn more about Steganography on Wikipedia. Image Steganography Hide images inside other images. How it works How to defeat it.

How to Hide Secret Messages in Audio - Audio Steganography

Hide image Unhide image. Hidden bits: 1. This is a project by James Stanley.There are many reasons to hide information but most common reason is to protect it from unauthorized access and people coming to know the existence of the secret information. In the corporate world audio data hiding can be used to hide and secure confidential chemical formulas or designs of new invention. Not only in commercial sector, it can also be used in used in the non-commercial sector to hide data that someone wants to keep private.

Terrorists organization have been using audio data hiding since long time to keep their communications secret and to organize attacks. We are going to talk about confidential information hiding with the help of information and data security solutions expert. Steganography is the science of hiding confidential information in a cover file so that only dispatcher and recipient know the existence of the confidential information.

Confidential information is encoded in a way so that the very existence of the information is hidden. The main objective of steganography is to converse securely in a completely invisible mode and to shun drawing doubt to the communication of hidden information.

Steganography not only prevents people from knowing about the hidden confidential information, but it also prevents others from thinking that somebody is communicating in a hidden way. If a steganography technique causes someone to believe there is hidden information in a carrier medium, then the technique has botched.

The essential technique of audio steganography consists of Carrier Audio fileMessage and Password. Carrier file is also called as a cover-file, which hides the confidential information. Essentially, in steganography message is the information that the sender desires that it should remain confidential.

Message can be image, plain text, audio or any type of file. Password is also called as a stego-key, and it assures that only the receiver who knows the password will be able to extract the confidential information or message from a cover-file.

The cover-file with the confidential information is called as a stego-file. The confidential information hiding procedure consists of subsequent two steps Identification of redundant bits in the cover-file.

Redundant bits are that bits that can he modified without corrupting the eminence or destroying the integrity of the cover-file. To insert the confidential information in the cover file, the redundant bits in the cover file is interchanged by the bits of the confidential information.

That's usually an effective approach in cases where the LSB substitution doesn't cause significant quality degradation, such as in bit bitmaps.This is a great way to send a secret message to a friend without drawing attention to it. Compare this method to simply sending someone an encrypted piece of text.

No matter how strong the encryption method is, If someone is monitoring the communication, they'll find it highly suspicious. You can link to this tool using this HTML code.

The cover-file with the confidential information is called as a stego-file. Common approaches are:. LSB Least Significant Bit approach is very famous approach and it replaces the least significant bit in some bytes of the cover file to conceal a sequence of bytes enclosing the hidden data. Using this approach you can hide a byte every eight bytes of the cover.

Parity coding is one of the most robust audio steganographic approach. In place of breaking a signal into individual samples, this approach breaks a signal into separate samples and inserts each bit of the confidential information from a parity bit. If the parity bit of a chosen region does not match the secret bit to be encoded, the procedure inverts the LSB of one of the samples in the region. Hence, the sender has different choices in encoding the secret bit. The phase coding method works by switching the phase of an initial audio segment with a reference phase that symbolizes the confidential information.

The persisting segments phase is changed in order to preserve the relative phase amid segments. In terms of signal to noise ratio, Phase coding is very effective coding approach. When there is a drastic change in the phase relation amid each frequency element, noticeable phase dispersion will happen.

But, as long as the alteration of the phase is adequately small, an inaudible coding can be attained. This approach relies on the fact that the phase elements of sound are not as perceptible to the human ear as noise is says ethical hacking training professor. The basic spread spectrum SS approach tries to spread confidential information through the frequency spectrum of the audio signal. This is like system, which uses logic of the LSB that spans the message bits unsystematically over the complete sound file.

Nevertheless, dissimilar to LSB coding, the Spread Spectrum approach spreads the confidential information through the frequency spectrum of the sound file using a code, which is sovereign of the actual signal. Thus, the final signal captures a bandwidth, which is more than what is actually needed for transmission.Services section navigation.
