What techniques might criminals use to hide data or activities?

Today, criminals engaged in digital crime can either hide information or hide data in plain sight as it travels along the World Wide Web. The two most common types of information-hiding practices are steganography and cryptography.

What are the mechanism involved in steganography?

embedding process is organized as follows, read the secret message character by character, randomize posi- tions at the end of two generated cover characters, create words from the generated cover characters, generate error detection code, and finally hide the generated key.

Is steganography encrypted?

When combined, steganography and cryptography can provide two levels of security. Computer programs exist which encrypt a message using cryptography, and hide the encryption within an image using steganography. Another form of steganography is in null ciphers, or unencrypted text messages.

What is steganography and its types?

There can be mainly two types of steganography techniques possible for MMS objects. Fragile steganography comprises of implanting information into a file which is destroyed if the file is modified. Video Technique: Works over video files.

Which method is used by steganography?

The Least Significant Bit technique( LSB) is most commonly used by steganography to hide text in an image file. In this method, the data is concealed by altering the last few bits in a byte required to encode a message. This method works really well in case of media files.

Where is steganography used?

The uses of steganography are as varied as the uses of communication itself. Obviously you can use it to send secret messages to a friend, colleague, or co-conspirator. You can use it to transport sensitive data from point A to point B such that the transfer of the data is unknown.

Is Steganography still used?

Is Steganography still used? Yes, Steganography is still popular among cyber criminals. Recent attacks show that security researchers found a new malware campaign that used WAV audio files to hide their malware. It is believed that the attackers used Steganography to embed the malicious code inside the WAV audio file.

What makes steganography unique?

Encryption is much simpler and far more data can be encoded in the same space. With techniques such as public-key encryption, you can even communicate without a secure channel. When steganography is used by itself, it’s security through obscurity, which can lead to the secret message being revealed.

What is a social steganography?

Social steganography is one privacy tactic teens take when engaging in semi-public forums like Facebook. While adults have worked diligently to exclude people through privacy settings, many teenagers have been unable to exclude certain classes of adults – namely their parents – for quite some time.

What are the advantages of steganography?

The advantage of steganography, over cryptography alone, is that messages do not attract attention to themselves. Plainly visible encrypted messages—no matter how unbreakable—will arouse suspicion, and may in themselves be incriminating in countries where encryption is illegal.

What is steganography and how it works?

Steganography is the art of hiding a message. … Steganography works by changing bits of useless or bot used data in regular computer files (such as graphics, sound, text, HTML) with bits of different, invisible information. This hidden information can be plain text, cipher text, or even images.

How do you detect steganography?

By looking at repetitive patterns, you can detect hidden information in stego images. These repetitive patterns might reveal the identification or signature of a steganography tool or hidden information. Even small distortions can reveal the existence of hidden information.

How do you use steganography tools?

Image Steganography You can hide text messages or files inside an image file. Just select the source file in which you want to hide the secret message and then select the file to hide or write the text message to hide. Select the output image location and then click on the start button to start encoding the file.

What is the difference between steganography and cryptography?

The steganography and cryptography are the two sides of a coin where the steganography hides the traces of communication while cryptography uses encryption to make the message incomprehensible. … The steganography does not employ changes in the structure of the message.

Who invented steganography?

Johannes TrithemiusThe first recorded use of the term was in 1499 by Johannes Trithemius in his Steganographia, a treatise on cryptography and steganography, disguised as a book on magic.

Why is steganography used?

The purpose of steganography is covert communication to hide a message from a third party. This differs from cryptography, the art of secret writing, which is intended to make a message unreadable by a third party but does not hide the existence of the secret communication.
