Machine Learning Approach to Mobile Forensics Framework for Cyber Crime Detection in Nigeria

The mobile Cyber Crime detection is challenged by number of mobile devices (internet of things), large and complex data, the size, the velocity, the nature and the complexity of the data and devices has become so high that data mining techniques are no more efficient since they cannot handle Big Data and internet of things. The aim of this research work was to develop a mobile forensics framework for cybercrime detection using machine learning approach. It started when call was detected and this detection is made by machine learning algorithm furthermore intelligent mass media towers and satellite that was proposed in this work has the ability to classified calls whether is a threat or not and send signal directly to Nigerian communication commission (NCC) forensic lab for necessary action

Artificial Intelligence Approach to Cyber Security

Cyber security is a major concern of developed and developing countries due to the high rate of attack and threat to the cyber space The aim of this research work was to develop a fuzzy logic system for cyber security Four inputs were used and three outputs was produced with their associated linguistic variables Triangular angular membership function was used to implement the system Fuzzy controller has an advantage of performing according to linguistic rules in the manner of how a human behaves The reasoning method in the fuzzy controller is also similar to that of the cyber expert handl

Assessing the Effectiveness of Adhoc-Network and Electronic Government in Abuja, Nigeria

E-Government is the use of information and communication Technologies (ICT) such as internet, smart phones,telecommunication, mobile company among others to interact between government and the citizens in running the affairs of the country such as decision making etc. The impact and potential of ICTs have not been fully exploited in the Nigerian context,leaving government in a weak position to formulate policy comprehensively and implement plans effectively. In addition to the implementation of e-government in some part of the Federal Capital Territory (FCT) of Nigeria Abuja, but its effectiveness is not impressive. The citizens connection to the government is limited it can be improved more easily using electronic means of communication, A reduction in corruption cases as accountability and transparency can also be increased, Equal opportunity will be given to all to access information irrespective of the person’s physical location or disability and the elimination of the bureaucracy experienced in government offices. This research work is aimed at assessing the effectiveness of e-government in federal capital territory of Nigeria Abuja using Seoul Metropolitan Government as a yard stick for measuring the effectiveness.Questionnaire was used as a primary method of data collection, internet and library as secondary data. The data obtained from the questionnaire has been analyzed using frequency table and percentage. The findings of this work shows that 41.91% of the respondents agree e-government initiatives have decreased civil servants corruption in Abuja, 46.81% of the respondents agree that E-government services has increased citizens trust in Abuja, 58.11% of the respondents believe that E-government initiative have increased the accessibility to the government in Abuja however 37.11% agree that Lack of Information Technology (IT) infrastructure is the major problem affecting E-government in Abuja

Cybersecurity and Cyber Forensics: Machine Learning Approach Systematic Review

The proliferation of cloud computing and internet of things has led to the connectivity of states and nations (developed and developing countries) worldwide in which global network provide platform for the connection.Digital forensics is a field of computer security that uses software applications and standard guidelines which support the extraction of evidences from any computer appliances which is perfectly enough for the court of law to use and make a judgment based on the comprehensiveness, authenticity and objectivity of the information obtained. Cybersecurity is of major concerned to the internet users worldwide due to the recent form of attacks,threat, viruses, intrusion among others going on every day among internet of things. However, it is noted that cybersecurity is based on confidentiality,integrity and validity of data. The aim of this work is make a systematic review on the application of machine learning algorithms to cybersecurity and cyber forensics and pave away for further research directions on the application of deep learning, computational intelligence, soft computing to cybersecurity and cyber forensics

Design of Miniaturized Multiband Patch Antenna Using CSRR for WLAN/WiMAX Applications

A novel miniaturized multiband, single-feed microstrip patch antenna is presented in this paper for WLAN and WiMAX applications. Both size reduction and multiband are obtained by etching the Multiple Complementary Split Ring Resonators (MC-SRR) on the ground plane of the normal patch antenna. At first, the normal patch antenna produces a single band of 5.15 GHz; 200 MHz (5.0500~5.2499). Subsequently, a Single Circular Split Ring Resonator (SC-SRR) is etched on the ground plane and produces a triple band of: 3.25 GHz; 288 MHz (3.1085~3.3964), 4.5 GHz; 101.3 MHz (4.4488~4.5501), and 5.22 GHz; 220 MHz (5.1191~5.3400) and Double Single Circular Split Ring Resonator (DC-MCSRR) with: 2.99 GHz; 60.7 MHz (2.9574~3.0181), 3.57 GHz; 324.7 MHz (3.4065~3.7312), and 5.1413 GHz; 115.4 MHz (5.0817~5.1971). The working bandwidths cover the desired frequency bands of WLAN 5.2 GHz and WiMAX 3.3/3.5 GHz. The proposed (MC-SRR) antenna can be employed to wireless communication systems due to its simplicity in design, compactness and miniaturization

HERDPhobia: A Dataset for Hate Speech against Fulani in Nigeria

Social media platforms allow users to freely share their opinions about issues or anything they feel like. However, they also make it easier to spread hate and abusive content. The Fulani ethnic group has been the victim of this unfortunate phenomenon. This paper introduces the HERDPhobia - the first annotated hate speech dataset on Fulani herders in Nigeria - in three languages: English, Nigerian-Pidgin, and Hausa. We present a benchmark experiment using pre-trained languages models to classify the tweets as either hateful or non-hateful. Our experiment shows that the XML-T model provides better performance with 99.83% weighted F1. We released the dataset at https://github.com/hausanlp/HERDPhobia for further research.Comment: To appear in the Proceedings of the Sixth Workshop on Widening Natural Language Processing at EMNLP202

Review of Groundwater Potentials and Groundwater Hydrochemistry of Semi-arid Hadejia-Yobe Basin, North-eastern Nigeria

Understanding the hydrochemical and hydrogeological physiognomies ofsubsurface water in a semi-arid region is important for the effective management of water resources. This paper presents a thorough review of thehydrogeology and hydrochemistry of the Hadejia-Yobe basin. The hydrochemical and hydrogeological configurations as reviewed indicated that the Chad Formation is the prolific aquifer in the basin. Boreholes piercing theGundumi formation have a depth ranging from 20-85 meters. The hydrochemical composition of groundwater revealed water of excellent quality,as all the studied parameters were found to have concentrations withinWHO and Nigeria’s standard for drinking water quality. However, furtherstudies are required for further evaluation of water quality index, heavy metal pollution index, and irrigation water quality. Also, geochemical, andstable isotope analysis is required for understanding the provenance of salinity and hydrogeochemical controls on groundwater in the basin

Compact patch MIMO antenna with low mutual coupling for WLAN applications

A compact triband microstrip patch MIMO antenna is proposed for WLAN applications. The antenna consists of two patches antenna elements, which are orthogonally placed to each other for high isolation at 2.4, 2.8 and 5.8 GHz frequency bands. On its ground plane, a Complementary Split Ring Resonators (CSRRs) is etched for size reduction and multiband generation. The proposed compact MIMO antenna covers an entire size of 58 x 45 x 1.6 mm3, with the patch size of 13.3 x 17.1 mm2. A 79% size reduction at 2.45 GHz was achieved for miniaturization, with a very low mutual coupling (S21 and S12) of -32 dB at all bands
