Recently, many digital techniques have been developed that perform steganography on electronic media, most notably sound and image files. Steganography works by following the concept of securing through obsecurity which is securing something by hiding it. Apparently, there are already many applications that can be used to reveal the hidden data. Therefore, this paper has been proposed to overcome this issue. This project model showed the combination of cryptography together with steganography and along with linear feedback shift register (LFSR) technique ensured the strength on the level of security for the message hiding. The combination of those concepts also ensured the robustness and efficiency of the method which the concept was encrypted data (plain text) had been hidden in the cover (image) in form of binary bits. The LFSR scattered the bits of the ciphertext and then those bits had been placed in the image randomly. This proposed method ensured that the difficulties of this image to be cracked by cryptanalyzer are high.

Therefore lightweight cryptography has become very vital and a strong demand. This paper meant to be a reference (for the cryptographic designers) on the lightweight block ciphers. It starts by doing a survey to collect the latest proposed ciphers, then to study them in terms of their algorithms specifications, hardware implementation and attacks. Finally, after the explanation and comparison, this research can be the basement for starting point to improve the lightweight block cipher in many directions like number of clock cycle, size of memory, number of Chosen Plaintext, Gate equivalence ( GE), throughput and attacks.

Many of these problems can be solve by building a Traffic Management System based on a Wireless Sensor Network (WSN). TMS is an innovative design for the road that saves time and money for the driver. This solution creates a city of intelligence, which can be control automatically through sensors. Some of the sensor nodes were portable and fixed that spread in buildings, streets, cars and traffic signals. We use two kinds of WSN motion sensors and physical sensors. We also use two kinds of WSN nodes: special-purpose sensor nodes and generic sensor nodes. Zigbee platform use to communicate between nodes in short speed and reduce energy consumption. The Database Management Systems (DBMS) supports a geospatial database by offering the GIS services such as fingerprints, photos and videos. The functionality of Network Operation Center (NOC) to supervise, maintains, and monitors the wireless network. GPS/routing protocols use to detect the location with longitude and latitude date information with Geographic information system (GIS) to discover geographic location for the city maps. The routing protocols were cheaper and provide same functionality as GPS. Our initial design describes the physical layer to explain the connectivity path from (NOC) to vehicle then network layer depending on routing protocols lastly, application layer shows the dashboard monitor system that controlled by (NOC) and how it solve a different issues in traffic problems.

Cryptography consists of a set of algorithms and techniques to convert the data into another form so that the contents are unreadable and unexplainable to anyone who does not have the authority to read or write on these data. The main objective of the use of encryption algorithms is to protect data and information in order to achieve privacy. This paper discusses an encryption method using base64, which is a set of encoding schemes that convert the same binary data to the form of a series of ASCII code. Also, The MD5 hash function is used to hash the encrypted file performed by Base64. As an example for the two protection mechanisms, Arabic letters are used to represent the texts. So using the two protection methods together will increase the security level for protecting the data.

Much of these problems and challenges can be solved by building a smart infrastructure based on wireless sensor network (WSN) that will be connected with backbone system depending on global network in various aspects: GSM, 4G, GPS, GIS, WIFI, WIMAX, and Cloud computing. This solution will create a city of intelligence which can be controlled automatically through sensors. Some of the sensors will be portable and carried by humans (Bracelet) or vehicles (Tag) while carrying necessary information in memory storage which can read/write into/from the sensors. Furthermore, other sensors can be fixed at important places while transmitting and receiving data. Recently, most of the researchers and IT companies proposed the idea of smart cities while focusing on a certain problem inside the city and giving a smart solution to that problem. For example, smart grid, smart meter, smart healthcare, traffic management system, smart energy, and smart Building. The idea behind this paper is to solve different city issues by using WSN and building an initial smart infrastructure using Kuwait city as case study.

The Al-Quran provides guidelines in dispute resolution through a third party called Sulh. Sulh refers to the process of mediation, arbitration and reconciliation that takes place when the parties involved agree on a process of resolving a dispute with a third party mediator, who eventually will ensure that both disputed parties will be satisfied by the outcomes. This work is focused on community mediation, which involved with the disputes between the community members. In Malaysia, Sulh were actually practiced by the Malays prior to the time of the Portuguese, the Dutch and the British. The session will be conducted by a third party who normally a respected and elder person in the society, whom also held the position as the headman (Penghulu or Ketua Kampung) or Imam (a religious leader). Nowadays, given the plural society of Malaysia, and the era of Internet, it is crucial for Sulh to be available online. With the use of ICT tools, Sulh can be promoted to society, and if it is a part of e-government efforts, then it will encourage the society to be involved with the government's mission. The online Sulh will not merely act as an interface for those parties involved. The challenges of making the online system secured, the correct ways of ensuring the data accuracy, understanding on methods that will be used for data propagation (among others), are existed in the domain of Computer Science (CS). There are many possible CS approaches, but the work will focus on Computational Intelligence (CI) techniques, with special interest in connectionist models.

A hash function is a transformation that takes input values and returns a fixed-size string, which is called the hash value. In this paper, a message will be hidden inside an image by using the Least Significant Bits (LSB replacement) technique. This method creates a random dispersion of bits of the message in the picture, and it would be difficult to extract the message without the password key .After creation of the hidden message, the image will pass it in hash function to obtain hashing value using the MD5 technique. This value will be fixed as long as there has been no change to the picture. If it has been manipulated after hiding the information, it can be discovered by the owner of the key because the serial hash value will be changed.

There are many applications with respect to security, sensitivity and secrecy. Face detection is the most important and first step of recognition system. This paper introduces a new approach to face detection systems using the skin color of a subject. This system can detect a face regardless of the background of the picture, which is an important phase for face identification. The images used in this system are color images which give additional information about the images than the gray images provide.

SVG (Scalable Vector Graphics) is a standard applied widely over several applications. It can be used to display vector graphics and text on web pages. SVG has witnessed several improvements and drew more attention as the devices used to surf the web are evolving in screen sizes and resolutions. This paper demonstrates how to convert normal font to SVG, then opens the opportunity for an engine that can render Arabic SVG font on different platforms and ends with challenges and solutions for them. We speculate that SVG will play great rule in future technologies and making use of it early on can lead to great benefits for Arabic language consumption over the web.

"Safeer" is a portal through which a student can apply for any of the 86 available academic, administrative and financial services. It was launched on Sunday 29th of January 2009; to link the Saudi ministry of higher education to Saudi cultural missions around the world. The quality was evaluated by seven experts and eight factors. Every dimension was evaluated by different number of items on 5 Likert scales. The evaluation instrument was the survey developed by the researchers upon the reviewed literature. It was found that, the Safeer portal quality is fairly good by 75% and it needs further improvement and development by 25%. The researchers recommend further investigation on empirical surveys, in order to develop more acceptable and authentic instrument. Also, it needs further understanding of evaluators. The evaluators' uncertainty is an ambiguity issue raised in the difference between internal consistency of the survey and the lack of their concordance.

In order to improve the retrieval performance an efficient and accurate system is required. Retrieving images based on the content i.e. color, texture, shape etc is called content based image retrieval (CBIR). The content is actually the feature of an image and is extracted through a meaningful way to construct a feature vector. Images having the least distance between their feature vectors are most similar. This paper gives comparison of three different approaches of CBIR based on image features and similarity measures taken for finding the similarity between two images. Results have shown that selecting an important image feature and calculating that through a meaningful way is of great importance in image retrieval. All the important features must be considered while constructing a feature vector and a proper similarity measure should be used for calculating the distance between two feature vectors. These parameters play very crucial role in deciding the overall performance of the any CBIR system. Some future direction were identified and under our future work.
