¶ … Steganography or "the process of embedding secret information into an innocent-looking carrier" has recently attracted new media attention because of a number of recent hacking attempts. However, the process is an old one which predates computers. "It should not be surprising that the first written report of the use of steganography is attributed to the Greek historian Herodotus. The reported method involved camouflaging a secret message within a hare corpse" (Zieli-ska, Mazurczyk, & Szczypiorski 2014). Linguistic steganography also has been popular for many decades, in which a hidden meaning is transmitted through words. "Linguistic steganography may be derived from the aforementioned technique of textual steganography, as it relies on the manipulations on the written (possibly even spoken) language with the aim of tricking the perception of an unaware dupe" (Zieli-ska, Mazurczyk, & Szczypiorski 2014).
Attempts to decode steganography attempts have...
On September 11, 2001" (Zieli-ska, Mazurczyk, & Szczypiorski 2014). Steganography is usually transmitted via a third party carrier who is unaware of what he or she is transmitting: the more innocent-appearing and popular the source, the better. However, there are some legitimate uses of the technique, including attempts to circumvent censorship; legitimate attempts to avoid detection via tracing; and also copyright protection (Zieli-ska, Mazurczyk, & Szczypiorski 2014).
The most common form of steganography in the modern area remains visually-altered, digital steganography. "Digital image steganography is mostly oriented toward tricking the human visual system into believing the perception of the image has not been manipulated in any way. Similar…

For his activities, he was banned from using the Oxford University computers. Here he also built his first computer from scratch, using a soldering iron, TTL gates, and M6800 processor and a television. Later, Berners-Lee worked with CERN, a nuclear research organization in Europe. Here he created a hypertext prototype system to facilitate sharing and updating information. Later, Berners-Lee combined hypertext with the Internet, and the World Wide Web was
S. stays one step ahead of the hackers. This is not easy, but the DoD could not have possibly thought it would be. Proper defenses, enhanced offensive capabilities and strategies to reduce risk by taking some sensitive data offline will all work to deliver better results in e-spionage of the United States. The Internet has become globalized, and nothing can take that back. That there are threats as the result of
Mail Server and iPhone 6 Encryption Email is very critical for business communication, although, many businesses organizations outsource their web-based services such as Google Apps or iCloud, however, these services are not a good option for businesses in possession of the critical data. Moreover, some organizations claim that the outsourced business emails are costs effective than hosting a private email server, nevertheless, the benefits of hosting private email servers outnumber
Cybercrime has become a serious problem in the world we live in. The abundance of personal computers that are readily available at relatively low prices has spawned the growth in Cybercrime all over the globe. As a result, law enforcement agencies have developed cybercrime forensics which is designed to track down those that are responsible for cyber crimes. The purpose of this discussion is to analyze this subject and discuss
Anonymous is one of the groups that can be seen as participating in this form of hacktivism, as is Wikileaks. Wikileaks is probably the best know hactivist site to the general public because of the sheer volume of political information that it has made public and because of the unapologetic nature of the owner of the site. This is unfortunate in many ways because it has given individuals a false
They would sometimes be using the school curriculum as an excuse to hack pertinent information that are government or privately owned. At some point, these students would be challenging themselves if they will be able to create and send unnecessary information (such as computer viruses) to other computer systems. This will provide extreme joy and satisfaction for these students. However, the issue here lies on how can this be
