In this modern era, where technology is increasing at rapid pace and made all day new developments, security is of highest priority. To protect facts into the unrecognizable form diverse technique are used for records hiding like steganography and cryptography techniques have been advanced. This paper securing the image by way of encryption is completed by LSB bits, DWT and RSA algorithm. This paper additionally presents new strategies wherein cryptography and steganography are mixed to scramble the information and in addition to cover the insights in some other medium through image processing (IP). The encrypted picture can be hiding in some other image by way of the use of LSB bits, DWT strategies so that the secret’s message exists. RSA algorithm applied, receiver will use his/her private key because the secret data have been encrypted by recipient public key. Hide encrypted image in the cover image by DWT. Extract encrypted image from cover image and decrypt text by DWT. The proposed scheme is implemented in MATLAB platform the use of preferred cryptography and steganography set of regulations. Calculate PSNR and MSE. Also calculate the entropy of cover image and stego image. This method is secure for communication in the digital world with the digital data transmission.

Protecting information on various communication media is considered an essential requirement in the present information transmission technology. So, there is a continuous search around different modern techniques that may be used to protect the data from the attackers. Steganography is one of those techniques that can be used to maintain the copyright by employing it to cover the publisher logo image inside the video frames. Nowadays, most of the popular known of the Video-Steganography methods become a conventional technique to the attacker, so there is a requirement for a modern and smart strategy to protect the copyright of the digital video file. Where this proposed system goal to create a hybrid system that combines the properties of Cryptography and Steganography work to protect the copyright hidden data from different attack types with maintaining of characteristics of the original video (quality and resolution). In this article, a modern Video-Steganography method is presented by employing the benefits of TC (Turbo code) to encrypt the pixels of logo image and Least two Significant Bit Technique procedure to embed the encryption pixels inside the frames of the video file. The insertion is performed in the frequency domain by applying the Fast Fourier Transform (FFT)on the video frames. The examination of the suggested architecture is done by terms of Structural Similarity Index, MSE (mean squared error), and PSNR (peak signal-to-noise ratio) by comparing between an original and extracted logo as well as between original and Steganographic video (averaged overall digital frames in the video). The simulation results show that this method proved high security, robustness, capacity and produces a substantial performance enhancement over the present known ways with fewer distortions in the quality of the video

Need of hiding information from intruders has been around since ancient times. Nowadays digital media is getting advanced like text, image, audio, video etc. To maintain the secrecy of information different methods of hiding have been evolved. One of them is Steganography which means hiding information under some other information without noticeable change in cover information. Video Steganography is the technique of hiding some covert message inside a video. In these paper work on improve data hiding capacity using video Steganography and use motion vector here for hiding data using LSB approach for hide text data. Using proposed system to improve images accuracy, embedding capacity. To enhance more security each bit of secret frames will be stored in covered frames. That are achieves good images quality when compared with existing method.

In the mechanical design constituent, numerical simulations method is mostly used for design instauration (or modification) and design optimisation. In the nowadays aim of work the first stage rotor leaf sword of a two-stage gas turbine has been analyzed for steady state thermal using ANSYS 16.2 an attempt has been investigated the effect of temperature on the turbine blade. A steady state thermal analysis has been carried out to investigate the focal point of the temperature flow rate which is been develops due to the thermal loading. An attempt is also made to suggest the best material for a turbine blade by comparing the results obtained for three different stuff such as Copper, Titanium and Nickel that has been considered for the analysis. The blade is modelled with SolidWorks 2015. The geometric model of the blade profile is generated with mathematically and extruded to get a solid model. In this work after finding the suitable materials, the analysis of different diam of hole also investigated. For different hole diameter, it has been pointed out that if the diameter of the hole is increased gradually with the constant number of holes, then the maximum temperature value and the total heat flux distribution decreases, then it grows again. Therefore, this present work the suitable diameter of hole also has been suggested for better performance in future.

This paper proposes a new compression technique and compares its performance with the popular adaptive Huffman encoding. The main objective of our approach was to shrink the original data optimally without losing data integrity. The above proposed algorithm employs static variable length non prefix codes for ASCII characters that have been assigned by analyzing the character occurring probabilities in variables lossless data file. We have used several lossless data formats like BMP, PNG, TXT, WAV, FLAC, AAC, WMV, DOC. For comparison and analysis we have used compression ratio, compression time, compression factor and saving percentage. A windows executable application has been constructed to facilitate and ease application usage. Moreover the addition of encryption algorithm(Caesar Cipher) will ensure the file protection and privacy. This compression can easily handle large files and without consuming much of system's resources.

This paper proposes a simple and robust method of audio data embedding into videos. Robustness in this method comes because of the use of double coding mechanism. Here double coding means using two kinds of codes on the same data one after another. This provides more security and reliability to the hidden data into video. As security is the most important matter of concern in present data communication scenario, thus our proposed method provides satisfactory results. The method performed in wavelet domain by using pseudo random codes and morse codes. The performance of this method is evaluated by MSE (Mean Square Error) and PSNR (Peak Signal to Noise Ratio). Further testing is done on videos after embedding, by exposing it to video compression technique. The obtained test result doesn't affect much to the quality of extracted audio data.
