One of the latest techniques that have been used in this area by researchers at the Mount Sinai School MOUNT SINAI Medical in New York in 1999, as they managed to hide the secret texts in chromosome strand human DNA by using a technique called genetic system coverage (Genomic Steganography) and by placing signs resolution to be agreed upon in the nuclei chromosomes and then integrate these with millions sentences and sent to the other end. Anyway, the researchers provide and found out many approaches while others enhanced the methods and the approaches of the steganography in order to improve the steganographic applications, in this part of the thesis a discussion about the existent methods or approaches for the steganography and how the researchers improve it within more than 10 years will be presented. The main use for it was for military and government messages, nowadays the approaches of steganography become widely used for many purposes ( Zaidan et al., 2009). The steganography has been used for long time before. Research in information hiding has tremendous increased during the past decade with commercial interests driving the field ( Jalab et al., 2009). It is a performance that inserts secret messages into a cover file, so that the existence of the messages is not apparent. ![]() For example, digital video, audio and images are increasingly embedded with imperceptible marks, which may contain hidden signatures or watermarks that help to prevent unauthorized copy ( Jalab et al., 2009). This technique has recently become important in a number of application areas. Information hiding is a technique of hiding secret using redundant cover data such as images, audios, movies, documents, etc. Simple steganographic techniques have been in use for hundreds of years, but with the increasing use of files in an electronic format new techniques for information hiding have become possible ( Shirali-Shahreza and Shirali-Shahreza, 2008). The formal definition for the steganography is the art and science of communicating in such a way that the presence of a message cannot be detected. Adding encrypted copyright information to a file could be easy to remove but embedding it within the contents of the file itself can prevent it being easily identified and removed. This makes steganography suitable for some tasks for which encryption are not, such as copyright marking. Steganography hides the existence of a secret message and in the best case nobody can see that both parties are communicating in secret. However, the main difference between them is that with encryption anybody can see that both parties are communicating in secret. Steganography and encryption are both used to ensure data confidentiality. Under this topic we can drive two techniques which are used to hide information one is the digital watermarking this technique used for two main things the first is for authentication purpose and the second is to demonstrate the intellectual property rights, the another technique is the steganography which is used mainly for hiding information from any unauthorized party, in this case the aim is to prevent the message being detected by any other party ( Kawaguchi and Eason, 1998 Majeed et al., 2009). ![]() The term of hide information is the process of covering some private or secrete data to make sure that there is no another party can disclose or altering it ( Al-Azawi and Fadhil, 2010). ![]()
