being attacked, encrypt it with a secret key to obtain an encrypted bit stream . For that AES encryption is used. After AES encryption, will embed at the fourth bit position of . Some related information about the mosaic image generation process into the mosaic image for use in the secret image recovery process are also embed at the last fourth bit position of . Such information, described as a bit stream I like M, includes the following data items: 1) encryption key; and 2) total length of before encryption. After all this process Target image with mosaic image, residual value and all information that required to recover original image are transmitted to receiver

Riordan Manufacturing conducts an information systems security review over IT security issues that exist in different plants to prepare for an upcoming audit in accordance to the Sarbanes-Oxley Act. Several elements of the organization 's information systems require revisions and updates to optimize physical and network security, data security, and Web security.

• Bridges, routers and switches and other critical devices will be fitted with UPS and tested monthly.

Information security is a major concept in today’s industrial and computer era, so security must be higher to protect the confidential data. Information security plays major role in computer and network security with the use of different cryptography algorithms that includes the encryption and decryption of data with the uses of the algorithm and the key. By means of text or numerical key for the encryption can be dangerous because with the several hack attacks that a key can be broken. So I have proposed a new mechanism that will replace the text key with the image pixels and can gain high security which cannot be easy to break without prior knowledge.

Our data is never at rest. Even when organizations depend on their database for storage, there is always copies of data somewhere else to be found. To service our men and women in the Army Reserves, data has to be manipulated at the local computer and then sent back to be stored back on the database. The very moment that data is moved and stored on a local machine for it to be manipulated is also the moment that the data is most vulnerable. Despite the concerted efforts to ensure data confidentiality the overall security depends efforts put forth by the weakest link. The insider threat is one of the hardest risk to mitigate, mainly due to their initial need to legitimately data access.

The concept of securing the messages through cryptography has a long history. The word cryptography stems from the two Greek words “crypto” and “grafein” meaning “hidden” and “write” respectively. Julius Caesar is credited with creating one of the earliest methods of cryptography system to send the message to his generals.

Abstract- The utilization of PC systems for information transmissions has made the need of security. The security of this intuitive media data should be possible with encryption or information concealing calculations. To diminish the transmission time, the information pressure is necessary. Since couple of years, an issue is to attempt to join pressure, encryption and information covering up in a solitary stride. Picture security turns out to be progressively critical for some applications, e.g., secret transmission, video reconnaissance, military and therapeutic applications. These days, the transmission of pictures is an every day routine and it is important to locate a proficient approach to transmit them over systems. They send Secret message over channel utilizing Cryptography and Steganography calculations by AES (Advanced Encryption Standard). It is utilized to scramble the information from plain content to figure content the other way around. There are two sorts of keys accessible in the cryptography, symmetric and asymmetric. There are utilizing symmetric key which is separated into two key, for example, private and open key. Open key is utilized for encryption and private key is utilized for decoding. The reversible information concealing method is utilized to recover the information and picture

The paper proposes data hiding with codeword substitution in encrypted H.264/AVC video streams. Here video is encrypted and data is hided in the video to maintain the security and privacy. In this way data hiding in encrypted domain without decryption preserves confidentiality of the content. By analyzing the property of H.264/AVC codec, the codeword of the intra-prediction modes, the code words of motion vector differences and code words of residual coefficients are encrypted with the stream ciphers. The data hider may embed additional data in the encrypted domain by using code word substitution technique, without knowing original content. Data extraction can be done in encrypted domain or in the decrypted domain.

In the version of security analysis and experimental results our proposed encryption scheme is fast and on the other hand provides good security and adds very less overhead on the data, this today is the requirement of most of the multimedia applications.

Since from the earlier times, people are bothered about how to securely transmit secret messages. Both Cryptographic techniques and steganographic techniques are used to achieve this aim. In cryptography, the existence of the encrypted message is visible to the world, whereas in Steganography, only the sender and the receiver know the existence of the message. Darrel Hankerson, Alfred Menezes, and Scott Vanstone explained the various arithmetic behind elliptic curves and addresses some issues that arise in ECC implementation in detail [1]. Lawrence C. Washington provides an introduction to both the number theoretic and the cryptographic sides of elliptic curves. To securely transfer text and image through the network, various techniques have been developed in recent years using Elliptic Curve Cryptography [2]. S. Maria Celestin Vigila and K. Muneeswaran proposed an image encryption algorithm using ECC. They generated the values of k and nB by a random number generator, Comparative Linear Congruential Generator (CLCG) to give credibility [3]. Ali Soleymani, Md Jan Nordin, and Zulkarnain Md Ali creates a mapping table which has the intensity values ranging from 0 to 255 along the row and the corresponding columns of each row contain the elliptic curve coordinates. All the pixels of an image are mapped to related points on the elliptic curve using the table and encryption is done using receiver’s public key. To view the cipher image, we refer to the mapping table and find the

Abstract - This paper proposes a data hiding method using adaptive pixel pair matching and data encryption approach for secret data communication. Steganography is the science of hiding secret data in plain sight within cover data so that it can be securely transmitted over a network. The idea of PPM is to use the values of pixel pair as a reference coordinate, and search a coordinate in the neighborhood set of this pixel pair according to a given message digit. Before hiding the data within cover image, two encryption schemes chaos encryption for secret messages and selective encryption for cover object are used to increase the data protection. The results will prove that the proposed method not only provides better performance than those of LSB and OPAP, but also is secure under the detection of some well-known steganalysis techniques.

wavelet based watermarking techniques shows to be immune to attacks, adding the quality of robustness to protect the hidden

In [1] the existing system focuses on the data securityapproach when combined with encryption and steganographic techniques for secret communication by hiding it inside the multimedia files. The high results are achieved by providing the security to data before transmitting it over the internet. The files such as images, audio, video contains collection of bits

In recent times providing security to the information is the major issue. There are many applications developed by the cyber terrorists, cyber criminals, script kidders etc. to steal the private information like passwords, ATM pin numbers, and credit card details so on. One of the solution to protect the information is Cryptography, which is the focus of this paper.
