Good Health Medical Centre - a private owned medical centre - has been providing general outpatient clinic services to public since 1999. The medical centre usually treats at least 200 patients everyday for both walk in or follow up cases. All patient data are recorded on paper forms that are stored as patient records in numeric order according to the patients IDs. There are more than 3000 patients records have been accumulated for the past 10 years and occulting a lot of space. Those materials...
An operating system (sometimes we called OS) is a process, in the first start the program to the computer, management, computer, and all other program load. Other program are called applications or application. The application makes use of the operating system through a defined application program interfaceservice request. In addition, users can interact with the user interface of the operating system, such as the direct command of the languega or graphical user interface. An operating system...
Consider that you are a privilege user of the internet and Internet Service Providers (ISP) provides a data to you as efficient as possible. But ISP can't give guarantees of accurate data transmission. For same data there are lots of fluctuations on different ends of same network. One end of the network gets data quickly but other ends of the same network gets the same data slower than first end. For example, anyone downloads a file from any website at night at the rate of the 500 kbps but in...
This chapter discusses the issues related to mobility management across heterogeneous networks. A review of various types of Vertical Handoff Decision Algorithm (VHDA) has also been presented in detail. In next generation heterogeneous networks, there are wide variety of networks with their own merits and demerits [24]. No single system is good enough to replace all other technologies. Therefore, there is a significant need for a single unified approach that integrates all disparate wireless...
There are various ways in which data can be encrypted in this ever changing digital world. There are many ways to secure and authenticate digital data. This report purely focused on cryptographic algorithms. This report also concentrated on implementation of an application specifically for encryption. The algorithm used for this is a combination of a few algorithms such as Vigenere cipher, RSA and hash functions. The strengths and weaknesses of different algorithms have been discussed further....
Microchip implantationAbstractState /purpose/ aim of research/Why interesting Microchip implantation as a method of identification has drew a lot of attention in recent years. As the need for more secure and efficient authentication device is emphasized, microchip implantation is very competitive and controversial.What is studied/ methodologyThis paper will begin by introducing some aspects of Radio Frequency Identification (RFID) technology. From there we will take a look at the properties and...
Abstract- For preserving privacy of the data in data engineering anonymization technique is used. Anonymization is a technique used to show the duplicate data instead of the original data to preserve the publication of the data. There are various anonymization techniques such as generalization, bucketization and slicing. Generalization have the data with less specific values. Bucketization spilts the tuples into buckets.Slicing divides attributes into columns and spilts the tuples into...
Information is very important to a company. It can help to operate a company. It is very dangerous if the company's information be stolen by the information theft. For an example, if the company's product information been stolen by the information theft, he can sell it to their competitor. The competitor will copy it and sell it to the public, it will cause a damage to the company. An information theft is someone who breaks into other computer without authorization. The information theft is...
Dynamic loading is an important mechanism for software development. It allows an application the flexibility to dynamically link a component and use its exported functionalities. Operating systems generally provide two resolution methods, either specifying the full path or the filename of the target component. This common component resolution strategy has an inherent security problem. Since only a file name is given, unintended or even malicious files with the same file name can be resolved...
Searching something in a list is a common task. That something is normally called as a record(s). I.e. employee number , employee address etc. The goal of a search algorithm is to find the item/record in shortest possible time, keeping in view the efficient resource utilization. The resource in question may be Storage requirements, CPU utilization/Total execution time etc.Data StructuresTo store and search/access the data efficiently a number of data structures are used. Some of the commonly...
