    Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. This scheme provides the ability to hide the data into a host image and then recover the host image without losing any information when the secret data is extracted. The...

    A Symmetric Key Based Steganography Algorithm for Secured Data Transfer

    Steganography is the art of hiding information efficiently into another media. It serves as a better way of securing message than cryptography which only conceals the content of the information. Original message is being hidden within a carrier such that the changes so occurred in the carrier are not observable....

    Assuage Bandwidth Utilization DDoS Attacks by Using Prototype Analyzer and Transfer Scheduling Scheme

    Denial-of-Service (DoS) attacks occur when the attacks are from a single source, whereas Distributed Denial-of-Service (DDoS) attacks occur when many compromised systems flood the resources or bandwidth of a target system. Although the authors cannot alleviate the Denial-of-Service or Distributed Denial-of-Service attacks entirely, they can limit the attacks by controlling...

    Risk Chain Prediction Metrics for Predicting Fault Proneness in Software Systems

    The paper presents two atypical risk chain prediction metrics for barometer coupling and accord in software systems. The authors' aboriginal metric, Ideal Coupling Between Object classes (ICBO), is based on the acclaimed CBO coupling metric, while the added metric, Ideal Lack of Cohesion On Methods (ILCOM5), is based on the...

    Performance Evaluation for V-Blast MIMO Systems Under Various Modulation Schemes Using Ricean Channel

    Wireless communication system with multi-antenna arrays has been a field of intensive research on the last years. The use of multiple antennas at both the transmitter and the receiver sides can drastically improve the channel capacity and data rate. The paper of the performance limits of MIMO system becomes very...

    Embedded System Design for a Multi Variable Input Operations

    There are several multivariable input systems with one or more outputs exist in nature or designed and implemented successfully artificially. The input parameters of the system may or may not bear any relationship with each other however, output or outputs of the system definitely possess fixed relationship with input parameters....
