The covert channels of type covert storage channels were used in this research to hide textual data or an (image hiding secrete data) in the transmission protocol layer and the internet protocol layer of TCP/IP module. We use IP protocol in designing covert channel by using Identification field, and use TCP protocol in designing covert channel by using Urgent Pointer field, and UDP by using Source Port field. Finally ICMP protocol by using Echo request message and Message field. The result of Covert channel after analyzing the protocols (IP, TCP, UDP, ICMP) header depends on the field that used in the designing the Covert channel. The access ratio of hidden data in the two protocols TCP/IP was %100. UDP protocol on the other hand depends on a mechanism of unsafe communication. ICMP protocol provided a good transmission, though unreliable, in that the message structure can be unreliable or clear.]]>

ABSTRACT Steganographic techniques are generally used to maintain the confidentiality of valuable information and to protect it from any possible theft or unauthorized use especially over the internet. In this paper, Least Significant Bit LSB-based Steganographic techniques is used to embed large of data in different color space models, such as (RGB, HSV, YCbCr, YIQ, YUV). The idea can be summarized by transforming the RGB value of the secret image pixels into three separate components into the pixels of the cover image. The measures (MSE, SNR, PSNR) were used to compare between the color space models, the comparisons proved that steganography with color systems (RGB and HIS) shown a best results.]]>

Therefore, it is up to users to choose for themselves whether an application is safe to use or not. It is important to say that there are differences between mobile devices and PC machines in resource management mechanism, the security solutions for computer malware are not compatible with mobile devices. Consequently, the anti-malware organizations and academic researchers have produced and proposed many security methods and mechanisms in order to recognize and classify the security threat of the Android operating system. By means of the proposed methods are different from one to another, they can be arranged into various classifications.

ABSTRACT Shoreline monitoring is important to overcome the problems in the measurement of the shoreline. Recently, many researchers have directed attention to methods of predicting shoreline changes by the use of multispectral images. However, the images being captured tend to have several problems due to the weather. Therefore, identification of multi class features which includes vegetation and shoreline using multispectral satellite image is one of the challenges encountered in the detection of shoreline. An efficient framework using the near infrared–histogram equalisation and improved filtering method is proposed to enhance the detection of the shoreline in Tanjung Piai, Malaysia, by using SPOT-5 images. Sub-pixel edge detection andthe Wallis filter are used to compute the edge location with the subpixel accuracy and reduce the noise. Then,the image undergoes image classification process by using Support Vector Machine. The proposed method performed more effectively and reliable in preserving the missing line of the shoreline edge in the SPOT-5 images.]]>

ABSTRACT In today’s world, the swift increase of utilizing mobile services and simultaneously discovering of the cloud computing services, made the Mobile Cloud Computing (MCC) selected as a wide spread technology among mobile users. Thus, the MCC incorporates the cloud computing with mobile services for achieving facilities in daily using mobile. The capability of mobile devices is limited of computation context, memory capacity, storage ability, and energy. Thus, relying on cloud computing can handle these troubles in the mobile surroundings. Cloud Computing gives computing easiness and capacity such provides availability of services from anyplace through the Internet without putting resources into new foundation, preparing, or application authorizing. Additionally, Cloud Computing is an approach to expand the limitations or increasing the abilities dynamically. The primary favourable position of Cloud Computing is that clients just use what they require and pay for what they truly utilize. Mobile cloud computing is a form for various services, where a mobile gadget is able to utilize the cloud for data saving, seeking, information mining, and multimedia preparing. Cloud computing innovation is also causes many new complications in side of safety and gets to direct when users store significant information with cloud servers. As the clients never again have physical ownership of the outsourced information, makes the information trustworthiness, security, and authenticity insurance in Cloud Computing is extremely difficult and conceivably troublesome undertaking. In MCC environments, it is hard to find a paper embracing most of the concepts and issues such as: architecture, computational offloading, challenges, security issues, authentications and so on. In this paper we discuss these concepts with presenting a review of the most recent papers in the domain of MCC.]]>

Fractals may be exactly the same at every scale, they may be nearly the same at different scales. The concept of fractal extends beyond trivial self-similarity and includes the idea of a detailed pattern repeating itself. The algorithms to constructing different fractal shapes in many cases typically involve large amounts of floating point computation, to which modern GPUs are well suited.

ABSTRACT Shoreline monitoring is important to overcome the problems in the measurement of the shoreline. Recently, many researchers have directed attention to methods of predicting shoreline changes by the use of multispectral images. However, the images being captured tend to have several problems due to the weather. Therefore, identification of multi class features which includes vegetation and shoreline using multispectral satellite image is one of the challenges encountered in the detection of shoreline. An efficient framework using the near infrared–histogram equalisation and improved filtering method is proposed to enhance the detection of the shoreline in Tanjung Piai, Malaysia, by using SPOT-5 images. Sub-pixel edge detection and the Wallis filter are used to compute the edge location with the subpixel accuracy and reduce the noise. Then, the image undergoes image classification process by using Support Vector Machine. The proposed method performed more effectively and reliable in preserving the missing line of the shoreline edge in the SPOT-5 images.]]>
