Steganography is the science of hiding information.^[1]
Without going into any detail, it is worth mentioning steganalysis, the art of detecting and breaking steganography.^[1]
In contrast to cryptography where the message is encoded, the purpose of steganography is to hide the fact that a message is being sent.^[2]
Additionally attack groups recently began targeting an organization in Italy, also leveraging a form of steganography.^[3]
What is steganography and how does it differ from cryptography?^[3]
Steganography is the art and practice of communication using hidden messages.^[4]
The least significant bits (LSB) based method is the well-known type of steganography in the spatial domain.^[4]
Anyone with malicious intent has the potential to abuse image steganography and cause much damage to a target.^[5]
An attacker goes through a multi-step process when creating a steganography technique.^[5]
The payload must also be determined: what do they want the steganography technique to accomplish?^[5]
The efficiency of the proposed steganography method relies on the color distribution in the color space.^[6]
For steganography of our method, color palette distribution should be analyzed rather than pixel color distribution in the image.^[6]
Depending on the image format and amount of concealed data, this Beta tool may not always detect steganography.^[7]
Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video.^[8]
This is where, again, steganography (or digital watermarking) plays a significant role.^[8]
Steganography is a technique that can hide code in plain sight, such as within an image file.^[9]
Attackers have even used steganography in network protocols, so-called ‘network steganography’, to carry concealed messages.^[9]
In the wild uses of steganography have affected both Windows and macOS platforms.^[9]
Steganography can be applied in computer technologies in numerous ways.^[10]
Hidden watermarks are another good example of steganography.^[10]
Our experts registered a surge in cybercriminal interest in steganography 18 months ago.^[10]
As expert Simon Wiseman noted at RSA Conference 2018, quality steganography is extremely difficult to spot.^[10]
Adversaries may use steganography techniques in order to prevent the detection of hidden information.^[11]
Duqu was an early example of malware that used steganography.^[11]
In steganography the embedding capacity is defined as the maximum number of bits that can be embedded in a given cover image.^[12]
In this section we propose a new algorithm for steganography.^[12]
Steganography provides an effective way for covert communication through hiding secret messages in public multimedia covers.^[13]
Steganography based on image covers gets more attention because images widely existed and are easy to acquire and complex enough.^[13]
During three key points (robustness, security, and capacity) of steganography, security seems more valued by researchers.^[13]
steganography show the effectiveness and accuracy of the proposed measure method.^[13]
A modified PVD-based steganography is proposed by Nagaraj et al.^[14]
Steganography is the art of covered, or hidden, writing.^[15]
The purpose of steganography is covert communication—to hide the existence of a message from a third party.^[15]
Knowledge of steganography is of increasing importance to individuals in the law enforcement, intelligence, and military communities.^[15]
Steganography, the practice of hiding information, has been around for centuries.^[16]
Steganography is the use of various methods to hide information from unwanted eyes.^[16]
In the centuries that followed, more modern forms of steganography were invented, such as invisible inks.^[16]
Steganography works by hiding information in a way that doesn’t arouse suspicion.^[16]
Steganography is the practice of hiding a secret message in something that is not secret.^[17]
Steganography is the practice of hiding a secret message inside of (or even on top of) something that is not secret.^[17]
These days, many examples of steganography involve embedding a secret piece of text inside of a picture.^[17]
The purpose of steganography is to conceal and deceive.^[17]
When spies in the Revolutionary War wrote in invisible ink or when Da Vinci embedded secret meaning in a painting that was steganography.^[18]
These defense techniques, however, address other aspects of the attack, not the steganography itself.^[18]
McAfee Labs’ June threat detection report notes that steganography is being used in more diverse types of attacks than ever.^[18]
Steganography is the art of covered or hidden writing.^[19]
The purpose of steganography is covert communication to hide a message from a third party.^[19]
Although the term steganography was only coined at the end of the 15th century, the use of steganography dates back several millennia.^[19]
Steganography hides the covert message but not the fact that two parties are communicating with each other.^[19]
Steganography includes the concealment of information within computer files.^[20]
Academic work since 2012 demonstrated the feasibility of steganography for cyber-physical systems (CPS)/the Internet of Things (IoT).^[20]
Digital steganography output may be in the form of printed documents.^[20]
The ciphertext produced by most digital steganography methods, however, is not printable.^[20]
The use of steganography can be combined with encryption as an extra step for hiding or protecting data.^[21]
Steganography is practiced by those wishing to convey a secret message or code.^[21]
There are advantages to using steganography combined with encryption over encryption-only communication.^[21]
Steganography is the process of hiding information, images, or audio messages inside another piece of information, image, or audio.^[22]
There are many ways to conceal information using Steganography.^[22]
These are just but a few methods by which black hat hackers frustrate ethical hackers using Steganography.^[22]
Steganography allows attackers to operate in stealth mode while conducting a serious attack.^[22]
