Analysis of NSL-KDD Dataset for Fuzzy Based Intrusion Detection System
(International Journal of Science and Research (IJSR), 2012-01-08) Mukosera, Macdonald; Mpofu, Thabiso Peter; Masaiti, Budwell
In a bid to provide useful information for intrusion detection, we focused on analyzing the NSL-KDD dataset. In this analysis, we seek to simplify the process of mining fuzzy rules by reducing the features and categorizing the dataset into various smaller clusters as smaller units of the dataset are easier to work with than the whole single large dataset. It is less complex to observe and discover sound fuzzy rules from a smaller dataset and this work serves as a foundation to a fuzzy logic based intrusion detection system. This paper presents a methodology for data preprocessing towards an intrusion detection system and Microsoft excel was used in the process.
Credit Scoring Techniques:A Survey
(International Journal of Science and Research (IJSR), 2012-01-01) Mpofu, Thabiso Peter; Mukosera, Macdonald
: Credit scoring is a numerical expression of the credit worthiness of an individual. A Value with a specific creditworthiness associated is assigned to an individual. Overall objective is to determine the creditworthiness of an individual. Ability of an individual to repay is determined in the credit scoring process. The credit scoring process looks at specific criteria such as income, credit history and many others. All this is done with the intent to reduce the overall default rate thereby decreasing the overall risk of financial institutions such as banks and micro lending institutions. Several credit scoring methodologies have been proposed and implemented and are varied from statistical based methods to Artificial Intelligence based techniques.
Digital Currency:The Emergence of Bitcoins
(International Journal of Science and Research (IJSR), 2014-06-06) Mpofu, Thabiso Peter; Masaiti, Budwell; Mukosera, Macdonald
: Bitcoins are a crypto currency whose concept was developed in 2009 by Satoshi Nakamoto. Bitcoins are digital currencies which operate on a peer to peer system. The system is decentralized as there is no central regulatory authority as with fiat currency. For an individual to transact you need a bitcoin wallet which has one or more private and public keys associated with it. Unlike fiat currency and electronic payment methods such as Visa and MasterCard which are based on trust, Bitcoin usage is based on cryptographic proof. Bitcoin usage has been on the increase and they can be converted into fiat currency through bitcoin exchange
Enhancing Security in Electronic Health Records using AES and PBKDF2: A case study of Zimbabwe e-health system
(IST-Africa, 2018-01-28) Mutandavari, Mainford; Matema, Chantel; Gotora, Tatenda; Mukosera, Macdonald; Manjoro, Wellington
As health IT is evolving, the use of traditional methods of storing patient information is being phased out. Notably Zimbabwe has begun digitalizing its medical records in most private and public health centres but limited internet connectivity and patient data harmonisation is still an issue. The viable solution lies in adopting Electronic Health Records (EHRs) which promote data sharing across healthcare providers while also ensuring data integrity and availability. Despite the many efforts by various researchers in suggesting strong encryption and biometric techniques to circumvent data loss or hacks, cyber criminals are getting more experienced due to the availability of more exploitation tools. This technical research presents an analysis of some of the widely implemented security techniques used in securing EHRs and proposes an enhanced hybrid mechanism for EHRs using AES and PBKDF2 within the Zimbabwe health care context. Observations made indicate the enhancement of data integrity, authentication and improved service delivery within the private and public health set up. Furthermore if scaled the e-health platform requires rigorous health personnel training in usage and changing mentality towards user acceptance.
The Impact and Application of 3D Printing Technology
(International Journal of Science and Research (IJSR), 2014-06-12) Mukosera, Macdonald; Mawere, Cephas; Mpofu, Thabiso Peter
3D printing also known as Additive manufacturing technology has been dubbed the next big thing and be as equally wide spread as cellular telephone industry. 3D printers print objects from a digital template to a physical 3-dimensional physical object. The printing is done layer by layer (Additive manufacturing) using plastic, metal, nylon, and over a hundred other materials. 3D printing has been found to be useful in sectors such as manufacturing, industrial design, jewellery, footwear, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and many others. It has been found to be a fast and cost effective solution in whichever field of use. The applications of 3D printing are ever increasing and it’s proving to be a very exciting technology to look out for. In this paper we seek to explore how it works and the current and future applications of 3D printing.
