Software requirement engineering uses different elicitation approaches from clients and other relevant stockholders communication. The elicitation techniques are used to elicit and analyse the requirement that is based on the presence of stakeholder availability. So, software products often fail to handle the demand of the stakeholder and users of the software. The requirement elicitation process gets complicated and labour-intensive when the traditional techniques are used with a larger population. This gives us the motivation to use a data-centred approach of Re engineering (RE) where requirements are elicited and collected on a larger scale. This study uses crowdsourcing integrated with the SCRUM approach of agile software development which is now popular in software development industries due to reducing cost and efficiency. Although it is important to identify the issues while integrating crowd source software development (CSSD) with SCRUM and resolve those issues. This study proposed a framework based on the integration of SCRUM with crowdsourcing development. The framework is designed in four major layers, the first layer is the vision and goal in which the raw document has been prepared, and the second layer is the prioritisation of task in which the product owner prioritised the task which should be developed first and which should develop later, the third layer is sprint planning and designing in which core document has been prepared and deliver it to the final project development, and the fourth layer is retrospective meeting in which all the development team and product owner and Scrum master conduct a meeting on a weekly basis to discuss the issues and changes that are made in the development process. This study suggested a conceptual framework that can combine CSSD and SCRUM to benefit from both software requirement development approaches and to address integration issues. The challenge for the researcher is to combine CSSD and SCRUM so that both software development methodologies can benefit from each other. Finally, issues are identified, and possible research directions are discussed for the future.

For the software developer, this is critical to building the best software application with misinterpreted requirements to handle the user's demands. The best software system will be developed and fulfil the actual needs of the stakeholder when better requirements are being gathered from the stakeholder.

The attacks of cyber are rapidly increasing due to advanced techniques applied by hackers. Furthermore, cyber security is demanding day by day, as cybercriminals are performing cyberattacks in this digital world. So, designing privacy and security measurements for IoT-based systems is necessary for secure network. Although various techniques of machine learning are applied to achieve the goal of cyber security, but still a lot of work is needed against intrusion detection. Recently, the concept of hybrid learning gives more attention to information security specialists for further improvement against cyber threats. In the proposed framework, a hybrid method of swarm intelligence and evolutionary for feature selection, namely, PSO-GA (PSO-based GA) is applied on dataset named CICIDS-2017 before training the model. The model is evaluated using ELM-BA based on bootstrap resampling to increase the reliability of ELM. This work achieved highest accuracy of 100% on PortScan, Sql injection, and brute force attack, which shows that the proposed model can be employed effectively in cybersecurity applications.

The cutting-edge studies on Automatic Speech Recognition approach have reported exceptional accuracy rates that are even comparable to human transcribersposing a question if machine has reached human performance. Automatic Speech Recognition can be used as a biometric authentication technique, which is essential in ciphering many applications used. In light of the Arabic language, only few studies have proposed to assess the effectiveness of using Automatic Speech Recognition in Arabic language; therefore, this study aims to implement Arabic speaker recognition using three different algorithms, including (i) Dynamic Time Warping (DTW), (ii) Gaussian mixture model (GMM), and (iii) Support Vector Machine (SVM). To measure the effectiveness of these algorithm in recognizing the Arabic speech, two datasets are used to train and test them, which are: (i) speech agent archive, and (ii) Arabic speech corpus. The results reveled that the DTW outperforms the GMM and SVM in terms of accuracy, precision, recall and fmeasure, as it achieves 95.7%, 96%, and 95%, and 96%, respectively.
