The Pros And Cons Of Steganography

Thus steganography is said to be a covert communication. In contrast to Cryptography, where the enemy is allowed to detect, intercept and modify messages without being able to violate certain security premises guaranteed by a cryptosystem, the goal of Steganography is to hide messages inside other harmless messages in a way that does not allow any enemy to even detect that there is a presence of second message [1]. Both steganography and cryptography are meant for secret communication but the approach is different. Hiding of secret message using steganography can be done in different forms like text steganography, image steganography, audio steganography and video steganography. Encoding secret messages in audio is the most challenging task while using steganography because human auditory system (HAS) is more perceptive than human visual system (HVS) [5]. Thus audio file is used as a cover file to hide secret data and it is called audio steganography. In Audio steganography, secret message is embedded into digitized audio signal which results into altering the binary sequence of corresponding audio file. There are several methods are available for audio

Steganography is the art of information hiding the message and prevent the detection of message. It hides data in the other file. The objective of steganography is to avoid attention towards the hidden message from the others except the recipient. In this present computer era, the mediums used to hide the messages are audio, video and image. There are two types of Image steganography. The first type is reversible steganography in which gives the result as the lossless host image when the secret data is extracted. On the other hand, the irreversible steganography results as slight destruction of host image when the secret data is extracted. The advantage of irreversible steganography is that it provides high

Security by obscurity is the process of hiding the design of a network and its implementation to ensure its weaknesses are unknown to potential

Steganography in the context of digital content piracy serves primarily as a method to track where digital assets are moving or who is receiving them. It can be a good solution for distribution of a small number of copies but becomes less effective when distributing on a wide basis. In order for it to be effective a content provider needs to recover the content by means of the unauthorized channel and examine the indicator marked on the copy. This is cumbersome for wide distribution but can be used on a broad basis such as by region. Region coding is used with many DVD releases for example but can also be considered a type of DRM (Andrew,

no one knows if this was a language or a way to communicate to others secretly or perhaps it could have been art.

In Ogden it is discussed that there may be inscriptions on a papyrus strip enclosed within the clay of the Louvre doll, as it is known from other

A VPN offers mobility and security for remote workers. The VPN uses an encrypted connection using the Internet. Remote workers wanting to use the Internet file server need authenticate their identity with a login id, password, RSA token, or smart card. The VPN can be used on company-owned laptops and personal electronic devices (PEDs). The VPN works by using data encapsulation. Encapsulating data packets into another set of data packets and data header this is the ‘tunnel’ used to send private data through the Internet. The data reaches its destination where the data is extracted from the 'tunnel'. It is then sent to the Application Layer where the remote worker can view or retrieve the files. This is a dedicated connection between the company and the remote worker computer. It is failsafe; the data sent through the VPN is encrypted by the sender and decrypted by the receiver. This prevents the data from being altered, read, or stolen by a hacker. Different cryptographic rules on each layer of the OSI model provide secure data transmission, authentication, confidentiality, and nonrepudiation. The cryptographic tunneling rules implemented for data security in each of the OSI layers (starting with the bottom layer) are listed

Data hiding is a commonly used AF technique which is defined as “the art of hiding the fact that communication is taking place, by the hiding of information in other information“(Tyagi, 2012, p.120). Data is hiding is used to essentially removing data from view so it is far less likely to be uncovered meaning that it won’t be used in the forensic investigation. The evidence will not be changed or

... there was to both outward patternings a hieroglyphic sense of concealed meaning, of an intent to communicate.There'd seemed no limit to what the printed circuit could have told her (if she had tried to find out) ...[2]

Some medical tattoos were used as ancient medicine. The tattoos found on female mummies in locations such as the pelvis could have been used for a therapeutic or medicinal purpose. Examining of the scars leaves no doubt that they were not just ornaments. “They were an established treatment for a condition of the pelvis, possibly being chronic pelvic peritonitis” (Tattoos).

To be able to fit into societies that the spies were in, they had to have forged documents to make them seem like officials, citizens, or any role they needed. During World War Two, the allies had excellent foragers who had up to date

Walking couriers were far too slow for urgent or vital messages; mounted couriers were then introduced as a faster method for message transportation. Though horses were faster, they required a lot of care, which took time, this included the horse as well as being wary of possible hazards, as if the horse became injured it would take much longer for the subject to reach their destination. This method of communication was seen as very efficient for the time period it was used in, but it is not very reliable, as Sending someone else to give another a message can be risky, shown in the game Chinese whispers. Due to this, another form of communication began to spark interest, writing. Messages began to be carved in stone, and over time began to be written on papyrus. This became more reliable as people were less able to edit the message written on it. Writing became a popular form of communication over years of evolution, many would use it to converse with each other, however it was only really used in instances when

To comprehend the risk that sniffers show first requires understanding how sniffers work. The way in which sniffers work relies on upon the kind of system. In a mutual media system, for example, a standard Ethernet, parcels sent along a system fragment travel all around along the wire. Any host associated with a fragment is equipped for catching all sessions inside of that section. For instance,

Pictures have been around long before words as a means of communicating. From ancient to modern civilizations, pictures and symbols have been used to convey messages and capsulize the history and culture of the society. Terms like hieroglyphics and emojis refer to systems of writing in which pictures and symbols represent ideas and sounds. This paper will examine four writing systems of ancient and modern societies that utilize pictures. Each of the writing systems used pictures along with letters. In some societies, pictorial uses were reserved for the society’s elite, but recently, the use of pictures as primary text has become more main stream. Throughout time, society 's use of pictures and symbols has transitioned from a more formal to informal method of written communication, however, it has still maintain its primary purpose.
