1.0 Introduction Steganography is a technique of hiding information in digital media. It has difference from cryptography, which means no one can know about the information existence. But by using steganography technique other person even can’t imagine the existence of information. Joining of cyberspace revolution increase the importance of steganography for people. Steganography is the practice of concealment of message from detection of hidden message. Steganography technique is using an array of secret communication method by which conceal the message from being discovered. Security of information become the fundamental issue nowadays, because of advancement in ICT. So steganography is the best technique to use for security of information …show more content…
By chance if user suspect the existence of information, then no way for user to access the information. 1.1 Problem Statement In first we had linguistic steganography. Which is technique of allowing any kind of digital information to hide within text based on some linguistic knowledge. But one disadvantage of linguistic steganography is that you should have good knowledge of linguist. In recent years as we know the development in technology and the digital data or information is transmitted through network very easily. So the message should be transmitted safely and with security by using steganography. So steganography is the technique of concealing of message or information within other message or image. With the advantage of that, it could not showing itself that I have any secret information. In steganography we can many types of format for delivering the secret information within it. But the best carrier file format is image file, as it has low frequency over internet. More variety of steganography technique can be used for hiding secret information. All of them has some differences in their complexity, strong and weak
Security by obscurity is the process of hiding the design of a network and its implementation to ensure its weaknesses are unknown to potential
Encryption technique is the translation of data into a secret code that will prevent hackers or identity thieves from being able to break or read the data that is sent across the network.
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,
This information should be protected by others for potential by some hacker threats,they can read and change the contents of the message and information and exploit this information for personal benefit[17] .
After the war people came back with ideas and popular toys came out. Like the hula hoop, it was very popular. But most people don’t know the history of the hula hoop. First wham-o made the hula hoop in 1958. Also it dates back to the 1400’s (Hula Hooping). The history of the hula hoop is how it first was discovered, what it looks like and how it became so popular.
No one is going to hand me success. I must go out & get it myself. That’s why I’m here, to dominate, to conquer. Both the world, and myself. — Unknown
make you feel happy. After reading both of the poems about residential schools “Stolen Children Stolen Souls” and “The Secret Path” several times, and gazing over them carefully, I have come to the conclusion that “The Secret Path” definitely has more meaning than “Stolen Children Stolen Souls. “The Secret Path” is more meaningful to me because of the pictures. I feel this way because they say “a
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
We all have things to hide. Whether it’s our passwords or something we have done in the past, we will often go to extremities just to keep these personal secrets from becoming known to our friends and family. However, in our constantly developing world, it is becoming more and more difficult to keep our personal life private.
Shug and Sofia are women that I think will influence Celie into finally standing up for herself; however, I personally am not a big fan of Shug. I have my reasons; first of all, she is sleeping with another woman's husband, and to add to that she’s done nothing but drag Celie through the dirt, even though Celie has done everything she can to nurse Shug back to health. Shug may not be the most high class sophisticated woman, and she may be a little sleazy and in short, she’s a woman of bad morals, but she’s always there for Celie. Her standard for men isn't very high, she's very much like a man, and she runs off at the mouth quite often; straightaway, she has all the characteristics of a villain. She abandoned Celie, but not until she knew
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
Stencils are complicated works of graffiti more similar to paintings, made simple with the use of a thick sheet of cardboard cut into a stencil. They achieve the appearance of paintings with only
This critical review is to investigate steganographic studies and their methods to either exfiltrate data or defend against data exfiltration. Steganography has one main purpose, to conceal data. Huang’s (2011) method, embedding steganographic data in inactive frames of low-bit rate audio streams went against the norm (Aoki, 2008), (Wu et al., 2006), used active frames of high-bit rate audio streams. Active high-bit rate audio streams have higher least significant bit counts, which presents added frames to conceal steganographic payloads (Huang et al., 2011). Howbeit, Huang (2011) demonstrated a new algorithm he administered to (VOIP) inactive frames of low-bit audio streams, which could carry higher capacity payloads than
Steganography (literally meaning covered writing) dates back to ancient Greece, where common practices consisted of etching messages in wooden tablets and covering them with wax, and tattooing a shaved messenger's head, letting his hair grow back, and then shaving it again when he arrived at his contact point. Steganography comes from the Greek steganos, or "covered," and graphie, or "writing". Synonymous to abstraction, the art and science of hiding information by embedding messages within other, seemingly harmless messages. Steganography takes cryptography a step farther by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data
Sometimes it is impossible or impractical to completely isolate the information then completely remove all traces of the information. In such instances, we may store the information for future use, such as to help resolve disputes between us. The same security safeguards will be in place to protect the information.
