The threat of an intruder accessing secret information has been an ever existing concern for the data communication experts. Cryptography steganography and visual cryptography are the most widely used techniques to overcome this threat. On the other hand, steganography embeds message into a cover media and hides its existence. Both these techniques provide some security of data neither of them alone is secure enough for sharing information over an unsecure communication channel and are vulnerable to intruder attacks. Although these techniques are often combined together to achieve higher levels of security but still there is a need of a highly secure system to transfer information over any communication media minimizing the threat of intrusion. In this paper we propose an advanced system of encrypting data that combines the features of cryptography, steganography along with multimedia data hiding.

Technology is on the ascendancy ever since it came to the foray. New and innovative technologies have been invented all over the world across all sorts of platforms. With such advanced technology around there are also an adverse side to it, security treats are most common nowadays leaving the network fragile and vulnerable. Of late we have been hearing stories of hacker attack at various important government organizations and defense websites. There should be a proper security measures to counter these malicious attacks.

Network security and cryptography is a subject too wide ranging to coverage about how to protect information in digital form and to provide security services. However, a general overview of network security and cryptography is provided and various algorithms are discussed. A detailed review of the subject of network security and cryptography in digital signatures is then presented. The purpose of a digital signature is to provide a means for an entity to bind its identity to a piece of information. The common attacks on digital signature was reviewed.

While in the beginning I have tried to give a general view about this topic. My efforts and wholehearted co-corporation of each and everyone has ended on a successful note. I express my sincere gratitude to.. I thank him for providing me the reinforcement, confidence and most importantly the track for the topic whenever I needed it. For many people, having access to this information is no longer just an advantage; it is essential.

 Отключить. Черт побери, немедленно отключить. Мидж появилась в дверях со свежей распечаткой в руке. - Директор, Стратмору не удается отключить ТРАНСТЕКСТ. - Что?! - хором вскричали Бринкерхофф и Фонтейн. - Он пытался, сэр! - Мидж помахала листком бумаги.

Он вечно навязывал что-то коллегам, например морковный сок, и убеждал их, что нет ничего важнее безукоризненного состояния кишечника. Хейл поставил масло на место и направился к своему компьютеру, располагавшемуся прямо напротив рабочего места Сьюзан.

Он даже представить себе не может, насколько хуже. Не в силах сдержать нетерпение, Беккер попытался позвонить снова, но по-прежнему безрезультатно. Больше ждать он не мог: глаза горели огнем, нужно было промыть их водой.

Целясь в торс, он сводил к минимуму возможность промаха в вертикальной и горизонтальной плоскостях. Эта тактика себя оправдала. Хотя в последнее мгновение Беккер увернулся, Халохот сумел все же его зацепить.

Сверху хлестала вода, прямо как во время полночного шторма. Стратмор откинул голову назад, словно давая каплям возможность смыть с него вину. Я из тех, кто добивается своей цели. Стратмор наклонился и, зачерпнув воды, смыл со своих рук частицы плоти Чатрукьяна. Его мечта о Цифровой крепости рухнула, и он полностью отдавал себе в этом отчет.

 Пожалуйста, - взмолилась. Но дверца не открылась. - Сьюзан, - тихо сказал Стратмор.  - Нужен код.
