  • They are LSB based Steganography, Steganography using the last two significant bits and Steganography using diagonal pixels of the image.[1]
  • This is an interesting observation, and I hope it makes sense to you, but it's not a big problem for a potential user of steganography.[2]
  • Steganography is the science of hiding information.[3]
  • Without going into any detail, it is worth mentioning steganalysis, the art of detecting and breaking steganography.[3]
  • In contrast to cryptography where the message is encoded, the purpose of steganography is to hide the fact that a message is being sent.[4]
  • Additionally attack groups recently began targeting an organization in Italy, also leveraging a form of steganography.[5]
  • What is steganography and how does it differ from cryptography?[5]
  • Steganography is the art and practice of communication using hidden messages.[6]
  • The least significant bits (LSB) based method is the well-known type of steganography in the spatial domain.[6]
  • Anyone with malicious intent has the potential to abuse image steganography and cause much damage to a target.[7]
  • An attacker goes through a multi-step process when creating a steganography technique.[7]
  • The payload must also be determined: what do they want the steganography technique to accomplish?[7]
  • The efficiency of the proposed steganography method relies on the color distribution in the color space.[8]
  • For steganography of our method, color palette distribution should be analyzed rather than pixel color distribution in the image.[8]
  • Depending on the image format and amount of concealed data, this Beta tool may not always detect steganography.[9]
  • Steganography is the practice of concealing a file, message, image, or video within another file, message, image, or video.[10]
  • This is where, again, steganography (or digital watermarking) plays a significant role.[10]
  • Steganography is a technique that can hide code in plain sight, such as within an image file.[11]
  • Attackers have even used steganography in network protocols, so-called ‘network steganography’, to carry concealed messages.[11]
  • In the wild uses of steganography have affected both Windows and macOS platforms.[11]
  • Steganography can be applied in computer technologies in numerous ways.[12]
  • Hidden watermarks are another good example of steganography.[12]
  • Our experts registered a surge in cybercriminal interest in steganography 18 months ago.[12]
  • As expert Simon Wiseman noted at RSA Conference 2018, quality steganography is extremely difficult to spot.[12]
  • Adversaries may use steganography techniques in order to prevent the detection of hidden information.[13]
  • Duqu was an early example of malware that used steganography.[13]
  • In steganography the embedding capacity is defined as the maximum number of bits that can be embedded in a given cover image.[14]
  • In this section we propose a new algorithm for steganography.[14]
  • Steganography provides an effective way for covert communication through hiding secret messages in public multimedia covers.[15]
  • Steganography based on image covers gets more attention because images widely existed and are easy to acquire and complex enough.[15]
  • During three key points (robustness, security, and capacity) of steganography, security seems more valued by researchers.[15]
  • steganography show the effectiveness and accuracy of the proposed measure method.[15]
  • A modified PVD-based steganography is proposed by Nagaraj et al.[16]
  • Steganography is the art of covered, or hidden, writing.[17]
  • The purpose of steganography is covert communication—to hide the existence of a message from a third party.[17]
  • Knowledge of steganography is of increasing importance to individuals in the law enforcement, intelligence, and military communities.[17]
  • Steganography, the practice of hiding information, has been around for centuries.[18]
  • Steganography is the use of various methods to hide information from unwanted eyes.[18]
  • In the centuries that followed, more modern forms of steganography were invented, such as invisible inks.[18]
  • Steganography works by hiding information in a way that doesn’t arouse suspicion.[18]
  • Steganography is the practice of hiding a secret message in something that is not secret.[19]
  • Steganography is the practice of hiding a secret message inside of (or even on top of) something that is not secret.[19]
  • These days, many examples of steganography involve embedding a secret piece of text inside of a picture.[19]
  • The purpose of steganography is to conceal and deceive.[19]
  • When spies in the Revolutionary War wrote in invisible ink or when Da Vinci embedded secret meaning in a painting that was steganography.[20]
  • These defense techniques, however, address other aspects of the attack, not the steganography itself.[20]
  • McAfee Labs’ June threat detection report notes that steganography is being used in more diverse types of attacks than ever.[20]
  • Steganography is the art of covered or hidden writing.[21]
  • The purpose of steganography is covert communication to hide a message from a third party.[21]
  • Although the term steganography was only coined at the end of the 15th century, the use of steganography dates back several millennia.[21]
  • Steganography hides the covert message but not the fact that two parties are communicating with each other.[21]
  • Steganography includes the concealment of information within computer files.[22]
  • Academic work since 2012 demonstrated the feasibility of steganography for cyber-physical systems (CPS)/the Internet of Things (IoT).[22]
  • Digital steganography output may be in the form of printed documents.[22]
  • The ciphertext produced by most digital steganography methods, however, is not printable.[22]
  • The use of steganography can be combined with encryption as an extra step for hiding or protecting data.[23]
  • Steganography is practiced by those wishing to convey a secret message or code.[23]
  • There are advantages to using steganography combined with encryption over encryption-only communication.[23]
  • Steganography is the process of hiding information, images, or audio messages inside another piece of information, image, or audio.[24]
  • There are many ways to conceal information using Steganography.[24]
  • These are just but a few methods by which black hat hackers frustrate ethical hackers using Steganography.[24]
  • Steganography allows attackers to operate in stealth mode while conducting a serious attack.[24]
