Algorithm-Based Data Generation (ADG) Engine for Dual-Mode User Behavioral Data Analytics

The increasing significance of data analytics in modern information analysis is underpinned by vast amounts of user data. However, it is only feasible to amass sufficient data for various tasks in specific data-gathering contexts that either have limited security information or are associated with older applications. There are numerous scenarios where a domain is too new, too specialized, too secure, or data are too sparsely available to adequately support data analytics endeavors. In such cases, synthetic data generation becomes necessary to facilitate further analysis. To address this challenge, we have developed an Algorithm-based Data Generation (ADG) Engine that enables data generation without the need for initial data, relying instead on user behavior patterns, including both normal and abnormal behavior. The ADG Engine uses a structured database system to keep track of users across different types of activity. It then uses all of this information to make the generated data as real as possible. Our efforts are particularly focused on data analytics, achieved by generating abnormalities within the data and allowing users to customize the generation of normal and abnormal data ratios. In situations where obtaining additional data through conventional means would be impractical or impossible, especially in the case of specific characteristics like anomaly percentages, algorithmically generated datasets provide a viable alternative. In this paper, we introduce the ADG Engine, which can create coherent datasets for multiple users engaged in different activities and across various platforms, entirely from scratch. The ADG Engine incorporates normal and abnormal ratios within each data platform through the application of core algorithms for time-based and numeric-based anomaly generation. The resulting abnormal percentage is compared against the expected values and ranges from 0.13 to 0.17 abnormal data instances in each column. Along with the normal/abnormal ratio, the results strongly suggest that the ADG Engine has successfully completed its primary task

Smart Chatbot for User Authentication

Despite being the most widely used authentication mechanism, password-based authentication is not very secure, being easily guessed or brute-forced. To address this, many systems which especially value security adopt Multi-Factor Authentication (MFA), in which multiple different authentication mechanisms are used concurrently. JitHDA (Just-in-time human dynamics based authentication engine) is a new authentication mechanism which can add another option to MFA capabilities. JitHDA observes human behaviour and human dynamics to gather up to date information on the user from which authentication questions can be dynamically generated. This paper proposes a system that implements JitHDA, which we call Autonomous Inquiry-based Authentication Chatbot (AIAC). AIAC uses anomalous events gathered from a user’s recent activity to create personalized questions for the user to answer, and is designed to improve its own capabilities over time using neural networks trained on data gathered during authentication sessions. Due to using the user’s recent activity, they will be easy for the authentic user to answer and hard for a fraudulent user to guess, and as the user’s recent history updates between authentication sessions new questions will be dynamically generated to replace old ones. We intend to show in this paper that AIAC is a viable implementation of JitHDA

Sharing Economy Digital Platforms and Social Inclusion/Exclusion: A Research Study of Uber and Careem in Pakistan

Part 2: Digital Platforms for DevelopmentInternational audienceThe sharing economy business models enabled by digital platforms are shifting the landscape of economic growth and nature of employment globally. This study focuses on digital travel industry of Pakistan and aims to explore the social and economic implications of sharing economy platforms. Drawing on the concepts of social inclusion/exclusion from ICT and IS literature, we examine the potential participation of digital platforms in social inclusion/exclusion of the society. We adopted an interpretive and qualitative research design. The data was collected through informal talks, observations and semi-structured interviews. For our research study, we selected two online ride-hailing companies operational in Pakistan, Uber and Careem. The study shows social impacts of sharing economy digital-platforms to enhance culture of trust, family confidence and women empowerment. It highlights the inclusion of unemployed groups through self-entrepreneurship that improve economic activities in the society. The study also identifies few contradictions and potential challenges that support social exclusion due to technology, such as biased gendered contribution in economic activities, generation/age constraints in usability and accessibility issues based on geographic locations
