Multimedia security is ever demanding area of research covering different aspects of electrical engineering and computer science. In this chapter, our main focus is encryption of JPEG2000 compatible images. Though both stream and block cipher have been investigated in the literature, but this chapter provides a detailed study of block cipher as applied to images, since JPEG2000 generates various subband sizes as blocks. In the first section, we briefly define various encryption components like wavelet transform, bit plane decomposition, XOR operation, artificial neural network, seed key generator and chaotic map functions, for interest of the reader. Later in section 2, we present literature review of various encryption techniques from two perspectives: applications to highlight scope of research in this domain; and approaches to provide overall view of multimedia encryption. The section three provides a new two-layer encryption technique for JPEG2000 compatible images. The first step provides a single layer of encryption using a neural network to generate a pseudo-random sequence with a 128-bit key, which XORs with bit planes obtained from image subbands to generate encrypted sequences. The second step develops another layer of encryption using a cellular neural network with a different 128-bit key to develop sequences with hyper chaotic behavior. These sequences XOR with selected encrypted bit planes (obtained in step 1) to generate doubly-encrypted bit planes. Finally,

Over the years, cryptography has been used to protect secrets, in a military capacity to make sure that either hackers, enemies of the countries, do not intercept sensitive formation. Ciphers, and encryption blocks are becoming so hard to break even the best super computers cannot break the codes in a timely fashion. Encryption has been improved over the years, also has been around for thousands of years and this paper is intended to explain about different forms of cryptography that either has been used or is still in use to this day. This paper is about

Cloud solution provides shared resources on demand, which is highly configured and computed, with minimized management efforts required. With the emergent of cloud services, individual users and enterprises with various capabilities would able to manage their data either locally or remotely, with servers located somewhere else, or they pay to have cloud providers manage the data.

With the emergence of rapid growth in technology in our society today, there is an enormous amount of data that is being stored. However, an important question to ask is how is sensitive or important data being protected. One popular method that is currently used for protecting data is through encryption, which is “the process of converting data to an unrecognizable or ‘encrypted’ form.” 1 This process ensures that only authorized individuals have access to the confidential encrypted message. Encryption can be applied to files, folders, storage devices, or entire volumes. Although encryption can be used to protect a variety of data types, there are many different encryption algorithms that can be used. The most common and popular encryption algorithms that are used include hashing, symmetric methods, and asymmetric methods.

In the present world lot of multimedia data is exchanged on internet and the percent of image data in that is highest. So we need to securely transmit that and this can be achieved by Image encryption.

Encryption has become a necessity in modern society due to the nature of the information we must interact with every day. Furthermore, the encryption of computer data is becoming increasingly important since much sensitive information is stored on our hard drives and human based codes are simply too easy for a computer to solve. All forms of encryption are based on cryptology which is "the science of analyzing and deciphering codes and ciphers and cryptograms". Cryptology and simple codes have been used as early as the Roman Empire. Encryption is used to ensure the confidentiality of a message that is being sent is not compromised as in case of the message being intercepted, it ensure that only authorized individuals can understand the contents. As technology, has been advancing, the complex nature of encrypting and decrypting messages have also been advancing the electronic age has brought forth many technological advances. With these advances came the need for security and tighter control on how we send information electronically over the Internet or through a network. Date encryption is, in its simplest terms, the translation of data into a secret code. To read an encrypted file, the receiver of the file must obtain a secret key that will enable him to decrypt the file. A deeper consider cryptography, cryptanalysis, and the Data Encryption Standard (DES) will provide a better understanding of data encryption.

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

Distributed computing is a pulling in innovation in the field of software engineering. In Gartner 's report, it says that the cloud will convey changes to the IT business. The cloud is changing our life by furnishing clients with new sorts of administrations. Clients get administration from a cloud without paying consideration on the subtle elements. NIST gave a meaning of distributed computing as a model for empowering omnipresent, helpful, on-interest system access to a mutual pool of configurable registering assets (e.g., systems, servers, stockpiling, applications, and administrations) that can be quickly provisioned and discharged with negligible administration exertion or administration supplier association. More individuals pay consideration on distributed computing. Distributed computing is productive and versatile however keeping up the strength of preparing such a variety of employments in the distributed computing environment is an exceptionally complex issue with burden adjusting getting much consideration for specialists. Since the occupation landing example is not unsurprising and the limits of every hub in the cloud contrast, for burden adjusting issue, workload control is essential to enhance framework execution and look after security. Burden adjusting plans relying upon whether the framework progress are essential can be either static or element. Static plans don 't utilize the framework data
