As per the above scenario, please find the short report below. The art of sending the message that is hidden in the grapical images is mainly called as \"STEGANOGRAPHY\". It is mainly followed , to protect the message from the unknown source. were other they cannot see the message that is hidded. Only the reciever and sender alone the way to encrypt or decrypt the hidden message from the images that are sent. 1) To make the message hidden in the image, first choose the message. There are so many softwares that are available, were the images if that are stored in the local drive, they can choosen. 2) Then type the information that you like to transfer , in terms of message. It may ask you for the password. Then you can create the password and enter it. Its mainly for the purporse of security. 3) After that if you , click hide message button in the available software, the message will be hidden. It will take few minutes to create the image with message. ONce it is created we will not able to crop the image of resize the image. Once the encryption is done, sender will send the message to intended reciepent. After recieving the message, the reciever need to decrypt the message. Following steps need to be followed to see the hidden messages. 1) Select the image needed for the decryption. 2) Enter the password that was sent by the sender, once the password is entered the password check will be done and reveal your message option need to be clicked. 3) Atlast the hidden message will be shown.

The secret sharing is a method to protect confidentiality and integrity of the secret messages by distributing the message shares into several recipients. The secret message could not be revealed unless the recipients exchange and collect shares to reconstruct the actual message. Even though the attacker obtain shares shadow during the share exchange, it would be impossible for the attacker to understand the correct share. There are few algorithms have been developed for secret sharing, e.g. secret splitting, Asmuth-Bloom secret sharing protocol, visual cryptography, etc. There is an unanswered question in this research about which method provides best level of security and efficiency in securing message. In this paper, we evaluate the performance of three methods, i.e. secret splitting, secret sharing, and recursive threshold visual cryptography for handwritten image security in terms of execution time and mean squared error (MSE) simulation. Simulation results show the secret splitting algorithm produces the shortest time of execution. On the other hand, the MSE simulation result that the three methods can reconstruct the original image very well.

With the increase in rate of unauthorized access and attacks security of confidential data is important. Now a day Cryptography and Steganography are the secure communication media for security purposes. This paper focuses on quantitative comparision of steganography technique such as improved LSB technique for RGB images, pattern based steganography technique and raster scan technique. The simulation has been done on MATLAB 2013 using 20 images and output of few has been shown in this paper. It has been concluded that the on the basis of various factors such as quantitative measures of the three techniques, pattern based steganography technique is the best among the other techniques w.r.t to security , irrespective of the fact that this technique has low capacity.

Encryption of Text in Image Over a Network

Stephen Hasford

Internet hacking has become common now a days and is increasing day by day. It is a high time to safeguard our data. There are several cryptographic methods and algorithms that are evolved and already exist. How about additional protection makes us stress free? In this paper, I present a unique design of cryptographic algorithm which is specifically designed for Auditory cryptography and visual cryptography to make the encryption and decryption technique stronger. The purpose is to make it very difficult to decode the file when an unauthorized user accesses the data. This algorithm is a combination of multiple techniques such as Ant Algorithm, Logical Gates Technique, Dual authorization PINs, Indexed Arrays. Combination of these techniques makes the algorithm unique and strong to secure the data. This research was implemented on audio files, images and video files. The study of the result shows effective way of masking the data as it is hard to decode without PINs. Also, performance of the algorithm is efficient during encryption and decryption process.

The art of information hiding has received much attention in the recent years as security of information has become a big concern in this internet era. As sharing of sensitive information via a common communication channel has become inevitable. Steganography means hiding a secret message (the embedded message) within a larger one (source cover) in such a way that an observer cannot detect the presence of contents of the hidden message [1]. Many different carrier file formats can be used, but digital images are the most popular because of their frequency on the Internet [2]. This paper intends to give an overview of image Steganography, its uses and techniques. It also attempts to identify the requirements of a good Steganography algorithm and briefly reflects on which Steganography techniques are more suitable for which applications.

Two advantages of using financial accounting information in decision making are : (i) Financial accounting provides an insight into the financial viability of the Company. Hence, based on the fund position, the decision can be correctly taken. (ii) Further, the financial accounting makes calculation of ratios easier, which can lead to a correct decision regarding the long term or short term profitability of the decision to be taken, as the case may be. Two disadvantages thereagainst are : (i) Financial accounting, if not done in accordance with the Generally Accepted Accounting Principles, can lead to a wrong picture being shown. This can affect the purchase power for a decision to be taken correctly. (ii) In major cases of decision making, budgets are also required to be analysed. This information is not provided for by financial accounting, but by management accounting.

The phylogenetic origin of the flu virus that caused the 2009 pandemics can be traced before 1918. Around 1918, the ancestral virus, of avian origin, crossed the species boundaries and infected humans as human H1N1 in North America. The same phenomenon took place, where the human virus was infecting pigs; it led to the emergence of the H1N1 swine strain, which later became the swine flu. Then the avian strain H1N1 infected humans again; this time the virus met the strain H2N2, and then the strain H3N2 originated. Around 1979, the avian H1N1 strain infected pigs and gave rise to Euroasiatic swine flu and H1N1 Euroasiatic swine virus. The 2009 outbreak is a triple reassortment process in a pig host of North American H1N1 swine virus, the human H3N2 virus and avian H1N1 virus which generated the swine H1N2 strain. Finally, the last step was in 2009, when the virus H1N2 co-infected a human host at the same time as the Euroasiatic H1N1 swine strain. This led to the emergence of a new human H1N1 strain, which caused the 2009 pandemic. In 2009, the World Health Organization raised the worldwide pandemic alert level to Phase 6 for swine flu, which is the highest alert level. This alert level means that the swine flu had spread worldwide and there were cases of people with the virus in most countries. Swine flu spread very rapidly worldwide due to its high human-to-human transmission rate and due to the frequency of air travel. This difference in the rate of spread is mainly due to the increased volume and speed of global transportation and to a minimal extent the increased virulance of the pathogen.

Plasma membrane of human is made of phospholipids; these are fluids so fluidity is reflected to the viscosity of the membrane. The fluidity is reciprocal to viscosity of the lipids of membrane. High viscosity causes to low fluidity. Cholesterol plays an important role for the binding of phospholipids in the membrane. Cholesterol has hydrocarbon ring. They interact with the hydrophilic head of phospholipids through their polar hydroxyl groups. This binding helps to decrease mobility of membrane to outside; make more rigid. When the temperature downs from 37 0C (200C) the cholesterol plays such important role because it prevents the closeness of lipid hydrocarbon chains by binding with them. When the temperature rises (400C) cholesterol holds some methylene group of fatty acid chains and thus increases the melting temperature.

One of the functions of skin is to regulate the temperature. The skin under the influence of homeostatic control regulates the body temperature. Skin coordinates with the blood vessels present in it to regulate the temperature. When the outside environment is hot with high temperature, the blood vessels are dilated to initiate the heat loos. Simulatneously, the sweat glands in skin produce sweat or prespiration along with salts. The sweat with the blow of wind from outside cools the body immediately and allow the drop of internal temperature. When the external environment is cold with low temperatures, blood vessels constrict and pores and sweat glands in skin are tightened initiating shivering to retain or generate heat in the body and to resist the cold temperatures. The heat or cold temperatures are snesed by the thermorteceptors present in the skin and that carry the sensory information to temperature regulation center in the brain (pituitary gland). The signals received back by the receptors integrate the message with skin and regulates the temperature. Solution One of the functions of skin is to regulate the temperature.
