One aspect of success in data communication is security. Data security can be done by using steganography. Steganography is a way to hide messages in the media in such a way that other people do not realize there is a message in the media. Many of the algorithms used in steganography one of which is the Least Significant Bit. In this research, the authors modify Least Significant Bit algorithms with Alternate Insertion method. Modification is doing of embedding and extracting messages process by changing the RGB values ??at each pixel of image data with confidential file by inserting message alternately and insertionly until the all message inserted. This steganography applications have input password that is used as the key of a message can't be opened in addition to the addressee so that the data will be kept confidential. The parameters used to measure the performance of the Least Significant Bit and Alternate Insertion are using runtime program and analysist algorithms of Big . The message insertion applications built by using C# (C Sharp) programming language. From the results of research that extracting process messages work faster than the embedding process. More larger of image in used it will be spend longer time to process the inserting message. Time complexity of algorithms (Big ) embedding and extracting processes obtained in testing the system is T (n) = (xy).

A selective bit-plane encryption scheme was proposed for securing the transmission of image data in mobile environments with a claim that it provides a high security viz. the encryption of the four most significant bit-planes is sufficient for a high image data security. This paper presents the security analysis of the said encryption scheme and reports new important results. We perform the security analysis of the bit-level encryption by considering the normal images and their histogram equalised enhanced images. We consider different bit-plane aspects to analyse the security of the image encryption, and show that the encryption of the four most significant bit-planes is not adequate. The contents of the images can be obtained even when all the bit-planes except one least significant bit-plane are encrypted in the histogram equalised images as shown in the results. The bit-plane level security analysis seems very useful for the analysis of the bit-plane level image encryption schemes.

Secure and efficient authentication mechanism becomes a major concern in cloud computing due to the data sharing among cloud server and user through internet. This paper proposed an efficient Hashing, Encryption and Chebyshev HEC-based authentication in order to provide security among data communication. With the formal and the informal security analysis, it has been demonstrated that the proposed HEC-based authentication approach provides data security more efficiently in cloud. The proposed approach amplifies the security issues and ensures the privacy and data security to the cloud user. Moreover, the proposed HEC-based authentication approach makes the system more robust and secured and has been verified with multiple scenarios. However, the proposed authentication approach requires less computational time and memory than the existing authentication techniques. The performance revealed by the proposed HEC-based authentication approach is measured in terms of computation time and memory as 26ms, and 1878bytes for 100Kb data size, respectively.

Recently, the rate of data transfer over the internet globally has increased and this called for more data security as security of data is of great concern for individuals as well as business owners. Cryptography and steganography are two major key players for data security technique. Cryptography is use to perform encryption on the secrete message while steganography hides the secrete message in digital media, image in this regards. This paper employed these two techniques using Advanced Encryption Standard (AES) for the cryptography and Least Significant Bit (LSB) for the steganography. Combining the two algorithms ensured data integrity, data security, and flexibility. The changes in the secrete message carrier (Stego) is insignificant and is often not noticeable by the nicked eyes, thus this make the interception of the message often difficult by intruder.

Technological advances have developed rapidly nowadays. These technological advances are also in line with the development of ways of communicating both orally and in writing. In terms of writing, maintaining aspects of data security and confidentiality is very important. Many technologies can be used to secure data such as cryptography and steganography. This research will use the First of File and End of File Steganography Algorithms to secure data. Steganography is the science of hiding messages or data in the media. The First of File and End of File methods are one of the many methods commonly used in the Steganography Algorithm. Generally, the First of File and End of File methods are not much different. The First of File method inserts a message at the beginning of the file, while End Of File inserts a message at the end of the file. This technology can also be applied again for the years to come. This research produces an overview after a review study of the application of the FOF and EOF steganographic algorithms, the speed of steganography and the differences in the image after steganography in terms of image size and pixel. Kemajuan teknologi sudah sangat berkembang dengan pesat pada era sekarang. Kemajuan teknologi ini juga seiring dengan berkembangnya cara berkomunikasi baik secara lisan maupun tulisan. Dalam hal tulisan, menjaga aspek keamanan dan kerahasiaan data sangatlah penting. Banyak teknologi yang bisa dipakai untuk mengamankan data seperti kriptografi dan steganografi. Penelitian ini akan menggunakan Algoritma Steganografi First Of File dan End Of File untuk mengamankan data. Steganografi merupakan ilmu menyembunyikan pesan atau data ke dalam media. Metode First Of File dan End Of File merupakan salah satu dari banyaknya metode yang biasa digunakan pada Algoritma Steganografi.Umumnya,metodeFirst Of File dan End Of File tidak jauh berbeda. Metode First Of File akan menyisipkan pesan diawal file sedangkan End Of File akan menyisipkan pesan di akhir file. Teknologi ini juga dapat diaplikasikan kembali untuk tahun-tahun kedepannya. Penelitian ini menghasilkan gambaran setalah studi review penerapan algoritma steganografi FOF dan EOF , kecepatan steganografi dan juga perbedaan gambar setelah di steganografi dalam hal ukuran dan pixel gambar.

A new partitioning method, called Wedging Insertion, is proposed for solving large-scale symmetric Traveling Salesman Problem (TSP). The idea of our proposed algorithm is to cut a TSP tour into four segments by nodes’ coordinate (not by rectangle, such as Strip, FRP, and Karp). Each node is located in one of their segments, which excludes four particular nodes, and each segment does not twist with other segments. After the partitioning process, this algorithm utilizes traditional construction method, that is, the insertion method, for each segment to improve the quality of tour, and then connects the starting node and the ending node of each segment to obtain the complete tour. In order to test the performance of our proposed algorithm, we conduct the experiments on various TSPLIB instances. The experimental results show that our proposed algorithm in this paper is more efficient for solving large-scale TSPs. Specifically, our approach is able to obviously reduce the time complexity for running the algorithm; meanwhile, it will lose only about 10% of the algorithm’s performance.
