On Securing Web-based Educational Online Game Using SSL Protocol

Currently, web-based online games is becoming popular in supporting learning process due to their effective and efficient tool. However, online games have lack of security aspect, in particular due to increase in the number of personal information leakage. Since the data are transmitted over insecure channel, it will be vulnerable of being intercepted by attackers who want to exploit user’s identity. This paper aims to propose an online web-based educational game, Vidyanusa which allows the students to register their personal information using a unique code, a user name and a password. It manages the users according to their schools, subject teachers and class levels. In addition, by adopting a unique code, the confidentiality of the user identity can be kept away from attackers. Moreover, in order to provide a secure data communication between client and server, Secure Socket Layer (SSL) protocol is adopted. The performance of the system after implementing SSL protocol is examined by loading a number of requests for various users. From the experiment result, it can be concluded that the SSL protocol can be applied to web-based educational system in order to offer security services and reliable connection.

Pseudonym-based privacy protection for Steppy application

Steppy is an Android-based application which is used for calculating the number of footsteps. The Steppy data is stored in the database and is shown on the Shesop website. When Personal Health Record (PHR) features on the website, privacy becomes vulnerable to various attacks so it needs reliable and effective technique for privacy preserving. In order to improve the security of data which are displayed on the Shesop website, anyone who access the site should not tamper without permission. In this paper, we adopt pseudonym technique and apply it to the Shesop website to construct secure application. We review the existing system and make some recommendations to preserve the privacy of user and we design pseudonym technique using time based one-time password (TOTP). Furthermore, we present an approach to address the security needs and pseudonym algorithms to tackle the security requirements. In addition, the proposed scheme can overcome the leaked information, the real identity of patients is never disclosed to anyone. Analysis result shows that the proposed scheme can enhance the user privacy against the adversary contained in the mobile healthcare networks (MHNs), which can be regarded as one of the most vulnerable conditions for patients data.

A development of non-invasive optical technique to investigate the feasibility of fatigue using skin color extraction

A development of Human-Computer Interface (HCI) technology is proposed to estimate and investigate users fatigue problem with non-invasive optical technique using web-camera sensor. Two kind of parameters are used such as heart rate (HR) as the physiological sign by processing the change of the skin color from face area and separating the signal color that normalized and analyzed using Independent Component Analysis (ICA) and then optimized with Fast Fourier Transform (FFT) algorithm. Eye blinking as the facial features also used as the second parameter that processed using centroid (color-based extraction) method which means observing the darkest area around the eyes in order to count the openness and closeness stage as the result. The image processing using computer vision technique and design to perform in real-time as a smart personal health care through desktop application. Notification also perform as an alert to remind the users condition while in a fatigue state and present in the measurement result which also used to review the proposed system performance. Furthermore, the whole system is developed and implemented to be a reliable and cost effective with providing a convenient, provision of health and social care, ease and simplicity of use to the end user.

3D spatial models for geometric description of spatial objects

Whilst thematic analysis and 2D spatial analysis are well studied, research on 3D spatial analysis is still at an intensive stage. Spatial relationships are the fundament of a large group of operations to be performed in Geographic Information System (GIS), e.g. inclusion, adjacency, equality, direction, intersection, connectivity, and their appropriate description and maintenance is inevitable. Similar to 2D variants, 3D GIS should be capable to perform metric (distance, length, area, volume, etc), logic (intersection, union, difference), generalisation, buffering, network (shortest way) and merging operations. Except metric operations, most of them require knowledge about spatial relationships. The third dimension increases drastically the number and complexity of all possible spatial relationships, compared with 2D GIS. A formalism for the detection of spatial relationships based on set topology notions has already been proposed by several authors, however the description of 3D spatial relationships is not sufficiently studied. The design of a spatial query language or the extending of existing languages, updating procedures to ensure topology consistency of database, etc., these are tasks that need further development. In this paper, the definition of a new spatial model will be given. It will be referred to as Geometric Domain Spatial Model. According to the proposed definition of an object, the geometry of each spatial object can be associated with four abstractions of geometric objects, i.e. point, line, surface and body.

Notice of Violation of IEEE Publication Principles 3D topological relations for 3D spatial analysis

This paper presents an integrated study on possible topological relationship between multidimensional simple objects in 0,1,2 and 3D space. The formal categorisation of spatial relationships is completed upon the 9-intersections model. The focus is on the definition of a unified set of conditions for eliminating relationships that cannot be realised in reality. The negative conditions are formulated on the basis of dimension and co-dimension of objects, and connectivity of boundaries. The set of 25 conditions is sufficient for deriving all the possible relationships mentioned currently in the literature and for specifying the relationships between surface and surface in 3D space. Drawings of example configurations verify the obtained results in 3D space.
