Title:Students’ Absence Registration and Reporting
Author Name:Rana D. Alanni, Atheer M. Al-saraaf and Mohammed M. Noori 
Synopsis:
Whole world and administrators of Educational institutions are concerned about the regularity of student;s attendance. Students overall academic performance is affected by the student's presence in his/her institute. Due to that, keeping track of student’s attendance becomes an important job in an academic environment. This paper presents a software design and implementation for taking student’s attendance and extract different kinds of absence reports. The software system is based on inserting, deleting, updating and querying of a database management system. In this system, the teachers engaging different classes are required to submit the attendance of the students present in their class regularly. The administrator monitoring this information, can extract different reports about a student’s weekly absence or whenever he/she wants the details using this system.

Title:Audio Steganography and Security by using Cryptography
Author Name:Hamsa A Abdullah, Aalaa A. Abdulameer and Israa F. Hussein 
Synopsis:
Audio steganography is a security technique by which a secret data to be transmitted over a public insecure channel is embedded into an audio cover object that hides it in such way that third party cannot detect the presence of the message. In this proposed system, DES cryptographic encryption algorithm is used to encrypt data before hiding it into the cover object for additional security. For the purpose of data encoding into audio samples, LSB coding algorithm is used. The overall system gives a relatively secure system that hides the secret message, a feature is provided by steganography, beside deformations the structure of the message, a feature provided by cryptography, which together leads to prepare the message travel through public channels.

Privacy Issues Surrounding Wearable Technology

Title:Privacy Issues Surrounding Wearable Technology
Author Name:Thomas Page
Synopsis:
Wearable devices give people the ability to track almost every facet of the lives through being embedded with a multitude of sensors. The collection of data through the use of these sensors is called 'personal metrics' - the quantification of everyday activity in order to change, improve or understand human behaviour. In order to deliver meaningful insight to the user, these personal metrics need to be sent to companies for analysis. This collection of data from companies ultimately causes complex concerns for consumer's privacy, most notably among young consumers, who are widely reported as having an increased acceptance for the sharing of their data. The study was achieved through first gaining-an understanding into the research area through reviewing literature, and then conducting primary research through an online survey. Overall, it was found that education into app privacy regulation and companies' use of data alone didn't have much effect on young adult consumer's behaviours. Furthermore, it was concluded that, young adult consumers appear to have an acceptance for the loss of their privacy, however some behaviours appear to show a level of concern. Nonetheless, due to limitations in the methodology of the research undertaken, it was concluded that further studies would be required in order to ensure the validity of the data.

Title:Analysis of TCP Variants Over Variable Traffic
Author Name:Varun Chauhan and Rajesh Kumar
Synopsis:
In today’s scenario most of the work carried out is accomplished through the internet. Internet plays a vital role in day-today’s regular activities and hence has become the backbone of our society. In internet the data is transferred from one place to another with the help of most commonly used protocol known as Transmission Control Protocol (TCP). TCP possesses various variants and each one has different criteria such as TCP, Tahoe, Reno, New-Reno and so on. Each variant performs in a different routine for different networks based upon the various key parameters. In this paper we have simulated various TCP variants with respect to different network parameters such as variable packet size, bandwidth and buffer size. This paper analyses the throughput, packet drop, delay and jitter of TCP variants evaluated over the above mentioned network parameters.

Defending Against Remote File Inclusion Attacks on Web Applications

Title:Defending Against Remote File Inclusion Attacks on Web Applications
Author Name:Bharti Nagpal, Naresh Chauhan and Nanhay Singh 
Synopsis:
Web applications are the fundamental pillars of today's world. Society depends on them for business and day to day tasks. Because of their extensive use, web applications are under constant attack by hackers that exploit their vulnerabilities to disrupt business and thus access confidential information. Remote File Inclusion (RFI) is a type of vulnerability most often found on websites. It allows an attacker to include a remote file, usually through a script on the web server. The attackers operate independently of one another with the goal of seeking exploitable vulnerabilities on the web. Different reasons were found for attack such as use of user-supplied input without proper validation. This can lead to something as minimal as outputting the contents of the file or more serious events. From observations, it is apparent that the detection and blocking of such attacks can be prevented by creating a blacklist of attack sources and a black list of URLs of remotely included malicious scripts. Remote file inclusion is a technique which is used to attack web applications mainly php applications from a remote server. RFI attacks are extremely dangerous as they allow a client to force a vulnerable application to run their own malicious code by including a reference pointer to code from a URL located on a remote server. When an application executes the malicious code it may lead to a backdoor exploit or technical information retrieval. Attackers attempt to remotely include these within the web applications. While the scripts are hosted at many locations, many of them are duplicates of each other, so the number of actual scripts that are used in the attacks are very small.

Secure Data Hiding by Optimal Placement of Queen Along Closed Knight Tour

Title:Secure Data Hiding by Optimal Placement of Queen Along Closed Knight Tour
Author Name:Abhishek Bansal, Sunil Kumar Muttoo and Vinay Kumar
Synopsis:
A knight tour starts from any square of the chessboard. A tour in which a knight visits every square on the board exactly once is called closed knight tour. A queen can move along column, row and diagonal in both forward and backward direction. In proposed method, the authors divide the cover image into non-overlapping 8x8 pixel blocks. For each block, they place a queen on a square and find the number of prime attacking positions by the queen along knight tour. Then the authors remove these attacking positions from the sequence of knight tour in 8x8 bytes block. They compute number of mismatches between bits in LSB position in 8×8 bytes blocks and corresponding number of bits from encrypted message to be hidden. The queen position that results in minimum distortion is chosen. The process is applied on each block in the cover image. The queen positions determined during embedding phase is recorded as the key and the same is used to extract the hidden message from stego cover. Experimental results performed on different images reveal that this method maintains high degree of imperceptibility. Randomization achieved through knight tour and queen moves provide another level of security against detection.

Title:Web Based Archiving System
Author Name:Khalid W. Hameed , Samer A. Ahmed and Amir A.Mohammed
Synopsis:
Today, people are more interested in efficiency, speed and more importantly in cost, in every walk of life. The management of work, industries, trade etc. which is called "Office work" is one of these. The office work may include saving information on paper in an ordered manner such that it may return to them in future. In order to overcome the difficulty in managing paper inventory and difficulty in searching for a particular document, the authors have designed and implemented an archiving system to save the burden of hard copies. The requirements had been first identified by analyzing the work nature. Upon these requirements for both the manager and user sides, the system was designed by creating a facility for each requirement, which in overall comprises the system. The designed system is easy, simple and web based. It was designed primarily based on XAMPP application and PHP language.
