Abstract

A novel method of message steganography is introduced to solve the disadvantages of traditional least significant bit (LSB) based methods by dividing the covering-stego image into a secret number of blocks. A chaotic logistic map model was performed using the chaotic parameters and the number of image blocks for generating a chaotic key. This key was then sorted, and the locations of blocks 1 to 8 were used to select the required blocks to be used as covering-stego blocks. The introduced method simplifies the process of message bits hiding and extracting by adopting a batch method of bits hiding and extracting. A comparative analysis was conducted between the outcomes of proposed method and those of prevalent approaches to outline the enhancements in both speed and quality of message steganography.

Abstract

In this paper we presented a new approach to manipulate a digital signal in order to create a features array, which can be used as a signature to retrieve the signal. Each digital signal is associated with the local binary pattern (LBP) histogram; this histogram will be calculated based on LBP operator, then k-means clustering was used to generate the required features for each digital signal. The proposed method was implemented, tested and the obtained experimental results were analyzed. The results showed the flexibility and accuracy of the proposed method. Althoug different parameters of the digital signal were changed during implementation, the results obtained showed the robustness of the proposed method.

Abstract

In this paper, we present an efficient dynamic array, called hybrid array list (HAL), whose structure is a linked list and each node is an array. In a HAL H, each node, called a chunk, is an array of size at most 2c, where c is an initial array size determined by the user. As the elements are added or deleted in H, it grows or shrinks by the number of nodes in the linked list as well as by the sizes of the chunks. We consider the operations append, insert and delete as well as a helping operation actual position in H. These operations run in O(1), O(m+c), O(m+c) and O(m) time, respectively, in worst case, where m is the number of chunks in H. These running times are much less than the worst case running time, which is O(n), where n is the total number of elements in H, taken by these operations in linked list or array. We implement HAL and compare these operations with similar operations in array list of Java and vector of C++. Our results show that H can perform substantially better when c is about half of the total number of elements.
