DIGITAL WATER MARKING FOR VIDEO PIRACY

ABSTRACT Digital watermarking is the process by which identifying data is woven into media content such as images, movies, music or programming, giving those objects a unique, digital identity that can be used for a variety of valuable applications. Imperceptible to the human senses yet easily recognized by special software detectors, a digital watermark remains constant even through recording, manipulation and editing, compression and decompression, encryption, decryption and broadcast witho...

DISTRIBUTED CHANNEL MANAGEMENT SYSTEM

ABSTRACT Wireless hotspots are typically implemented using 802.11 APs. Each AP typically operates on a single, administrator-configured wireless channel. Each client associates with a single AP and subsequently interacts with this AP alone, on the AP’s configured channel. As a basic design rule, APs within radio frequency (RF) range of each other are set to different ‘non-overlapping’ channels. Proper assignment of channels to APs is important so that the network can take full advantage...

DISTRIBUTED COLLABORATIVE KEY AGREEMENT AND AUTHENTICATION PROTOCOL FOR DYNAMIC PEER GROUP

ABSTRACT We consider several distributed collaborative key agreement and authentication protocols for dynamic peer groups. There are several important characteristics which make this problem different from traditional secure group communication. They are: 1) distributed nature in which there is no centralized key server; 2) collaborative nature in which the group key is contributory (i.e., each group member will collaboratively contribute its part to the global group key); and 3) dynamic natu...

DISTRIBUTED DATABASE ARCHITECTURE FOR GLOBAL ROAMING IN NEXT-GENERATION MOBILE NETWORK

ABSTRACT The next-generation mobile network will support terminal mobility, personal mobility, and service provider portability, making global roaming seamless. A location-independent personal telecommunication number (PTN) scheme is conducive to implementing such a global mobile system. However, the nongeographic PTNs coupled with the anticipated large number of mobile user’s in future mobile networks may introduce very large centralized databases. This necessitates research into the desig...

DISTRIBUTED METADATA MANAGEMENT FOR LARGE CLUSTER-BASED STORAGE SYSTEMS

ABSTRACT An efficient and distributed scheme for file mapping or file lookup is critical in decentralizing metadata management within a group of metadata servers. This paper presents a novel technique called Hierarchical Bloom Filter Arrays (HBA) to map filenames to the metadata servers holding their metadata. Two levels of probabilistic arrays, namely, the Bloom filter arrays with different levels of accuracies, are used on each metadata server. One array, with lower accuracy and representin...

DESIGN AND IMPLEMENTATION OF DISTRIBUTED SYSTEM SIMULATOR FOR PUBLISH-SUBSCRIBE MODEL

ABSTRACT The characteristics of publish/subscribe technology are of synchronism and loosely coupled. This phenomenon makes producers and consumers are de-communicated in temporal and spatial domains during processing. It requires develop a dynamic integration in today's large-scale, distributed information system. This paper introduces a Semantic Integration Data Model (SIDM) for publish/subscribe systems, within which model subscription module is designed. The model contains a matching algor...

DESIGN AND IMPLEMENTATION OF ONLINE DRUG CONTROL INFORMATION SYSTEM (NAFDAC ENUGU STATE)

ABSTRACT Drug availability, distribution andcontrol are majorly concern in health development as drugs constitute an important aspect of health development technology (Silverman, Lydecker and Lee, 1990). In Nigeria particularly since the mid 1980’s shortage of drugs and other technologies have become pervasive threats to the medical care system (Ohuabunwa, 2002), the major problem however seems to lie within the drug distribution and control channel. The sum total of the effect is the incre...

COMPUTER AIDED TUTORIALS IN ADDITION TO CONVENTIONAL TUTORIALS TO IMPROVE LEARNING IN HYPERTEXT MARK UP LANGUAGE

INTRODUCTION Computer aided teaching series is becoming an efficient and reliable means of teaching and learning. The development and continual dominance of high level procedural language enables the development and distribution of standard tutorial software or with the help of sophisticated programs the computer can serve as a tutor or a teacher on any subject. Like with human being, the computer can be used to teach you what you don’t know and make it understandable to you.  A computer a...
