Our world is making its way toward complete digitization, with more and more data going to the Internet. Thus, the security of the data has become one of our utmost responsibilities. Strong and secure cryptography and steganography techniques have become the need of the hour to defend against modern adversaries. In this article, a novel scrambled data hiding approach is proposed to secure the sensitive information used in communications. The lacuna in the existing data hiding approaches is the loss of originality in the sensitive data to be attached, leading to poor information quality. This issue is addressed in the proposed approach by encrypting the data using the triple data encryption standard (DES) algorithm. The scrambled data are hidden in the audio file using the least significant bit (LSB) embedding. Experiments were conducted, and the proposed approach secured the sensitive information significantly without the loss of information quality. Furthermore, the secured information is retrieved by only the authenticated users with high quality. [ABSTRACT FROM AUTHOR]

This paper provides an in-depth analysis of the history of DES and its successor Triple DES in the security market and secure data encryption. The different variations and improvements that have been proposed in research related to the uses of Triple DES since before it was approved as a standard for data encryption worldwide are studied. It is also important to mention that the proposals collected and analyzed are from different parts of the world, which solidifies the level of research carried out, due to the variety of sources found. In this way, the history of this algorithm is traced in order to provide the reader with a broad perspective on how it works and the different uses that have been made of it. Finally, it's determined that DES and 3-DES have been algorithms widely used in security information systems, but currently they are vulnerable to different attacks such as brute force and differential cryptanalysis, because of this it is suggested the use of other algorithms, for instance AES, or to include improvements in the DES and 3-DES implementation.

Cloud computing may be defined as management and provision of resources, software, application and information as services over the cloud which are dynamically scalable. Fault tolerance includes all the techniques necessary for robustness and dependability. The main advantages of using fault tolerance in cloud computing include failure recovery, lower costs and improved standards in performance. Even though the benefits are immeasurable, the element of risk on user applications due to failure remains a major drawback. So our suggested technique utilizes the effective fault tolerance method with the encryption algorithm. To improve the security of the recommended technique, triple-DES encryption algorithm is employed before the data transmission. For the transmission of encrypted data, the implemented method selects the minimum fault tolerance node. So the recommended technique utilizes the effective classification technique. Here, improved support vector machine (ISVM) classifier is used to classify the nodes based on its feature value and the content similarity each node. The proposed ISVM helps in predicting the faults if available, earlier before it occurs. The various parameters considered in our proposed system are accuracy, service reliability and availability. In the proposed method, the accuracy value of the fault tolerance is 79% which is better than in the existing method. The proposed method will be implemented in JAVA with CloudSim.

This work presents an approach for the applying Triple DES (TRIPLE DES) based on using genetic algorithm by adding intelligent feature for TRIPLE DES with N round for genetic algorithm. Encapsulated cipher file with special program which send an acknowledgment to a sender to know who decipher or broken to crash it , Thus it is considered as the initial step to improve privacy. The outcome for proposed system gives a good indication that it is a promising system compared with other type of cipher system. [ABSTRACT FROM AUTHOR]
