<p>The purpose of this thesis is to look into the differences between the theoretical frame-works of Realism and Feminism in general as well as their differences with regards to security and referent objects to security.

That is how a shift in the referent objects could change outcome and success or failure in the case studied.</p><p>This is done by a theory testing study based upon literature within the topics of Realism and Feminism, by mainly Morgenthau (1993) with regards to Realism and Ti

Abstract:

The Internet of Things (IoT) is seen as one of the next Internet revolutions. In a near future the majority of all connected devices to the Internet will be IoT devices. These devices will connect previously offline constrained systems, thus it is essential to ensure end-to-end security for such devices. Object Security is a concept where the actual packet or sensitive parts of the packet are encrypted instead of the radio channel. A compromised node in the network will with this mechanism still have the data encrypted ensuring full end-to-end security. This paper proposes an architecture for

Recently, there is a great interest in moving object tracking in the fields of security and surveillance. Object recognition under partial occlusion is the core of any object tracking system.

The intended use of the system is to recognize and track external vehicles entered inside a secured area like a school campus or any army base.

Following the success of software engineering design patterns, security patterns are a promising approach to aid in the design and development of more secure software systems. At the same time, recent work on aspect-oriented programming (AOP) suggests that the cross-cutting nature of software security concerns makes it a good candidate for AOP techniques. This work uses a set of software metrics to evaluate and compare object-oriented and aspect-oriented implementations of five security patterns--Secure Base Action, Intercepting Validator, Authentication Enforcer, Authorization Enforcer, and S

The self-defending object (SDO) concept is an extension to the object-oriented programming paradigm, whereby those objects that encapsulate the protected resources of a security aware application (SAA), are made aware of, and responsible for, the defence of those resources. That defence takes two forms, the enforcement of mandatory access control on protected resources and the generation of the corresponding portion of the SAA's audit trail. The SDO concept acts as the philosophy that guides the application level mandatory access control within SAAs which ensures that the provided access contr

First, the development of an optimised software radar signal processor will be outlined. Through use of threading and GPU acceleration, high data processing rates were achieved using standard PC hardware. The flexibility of this approach, compared to specialised hardware (e.g. DSP, FPGA etc…), allowed the processor to be rapidly adapted and has produced a significant performance increase in a number of advanced real-time radar systems.

Web crawlers are a fundamental component of web application scanners and are used to explore the attack surface of web applications. Crawlers work as follows. First, for each page, they extract URLs and UI elements that may lead to new pages. Then, they use a depth-first or breadth-first tree traversal to explore new pages. In this approach, crawlers cannot distinguish between "terminate user account" and "next page" buttons and they will click on both without taking into account the consequences of their actions.

碩士<br>國立交通大學<br>多媒體工程研究所<br>96<br>A vision-based vehicle system for security patrolling in indoor environments using an autonomous vehicle is proposed. A small vehicle with wireless control and a web camera which has the capabilities of panning, tilting, and zooming is used as a test bed. At first, an easy-to-use learning technique is proposed, which has the capability of extracting specific features, including navigation path, floor color, monitored object, and vehicle location with respect to monitored objects. Next, a security patrolling method by vehicle navigation with obstacle avoidance

Abstract:

Partially restricting access to objects enables system designers to finely control the security of their systems. We propose a novel approach that allows granting partial access at method granularity on arbitrary objects to remote clients, using proxy objects. Our initial approach considers methods to be either safe (may be invoked by anyone) or unsafe (may be invoked only by trusted users). We next generalize this approach by supporting Role-Based Access Control (RBAC) for methods in objects. In our approach, a policy implementer annotates methods, interfaces, and classes with roles. Our sy

Abstract:

The protection of digital images and video from unauthorized access is important for a number of applications, including privacy protection in video surveillance and digital rights management for consumer applications. However, traditional cryptographic methods are not well suited to digital visual content. Applying standard encryption approaches to the entire content can require significant computational resources due to the large size of the data. Furthermore, digital images and video often need to be manipulated,such as by resizing or transcoding, which traditional encryption would hinder.

Such control-flow hijacking attacks exploit a gap between high level language semantics and the machine language that they are compiled to.

Abstract:

This study explores the utilisation of spatial technologies as a tool to analyse and combat crime. The study deals specifically with remote sensing and its potential for being integrated with geographical information systems (GIS). The integrated spatial approach resulted in the understanding of land use class behaviour over time and its relationship to specific crime incidents per police precinct area. The incorporation of spatial technologies to test criminological theories in practice, such as the ecological theories of criminology, provides the science with strategic value. It proves t
