To mitigate password vulnerabilities, Multi-Factor Authentication, comes as a solution. I have worked on the user side of privacy and security by following qualitative, quantitative, and mixed methods to provide actionable recommedations and effective insights for improving security hygiene of individuals and in turn enable protecting the online user data by exploring mental models and user experience.
Social Media Privacy and Security
Collaborators: Dr. L. Jean Camp, Dr. Apu Kapadia, Dr. Sameer Patil, Dr. Tousif Ahmed, Dr. Irina Shklovski, Jayati Dev, Abu Salem Noman, Morgan L Brockman.
Social media privacy and security is a major concern due to technological advancement and an increased user involvement. I have worked on several social media and Mobile messaging platforms, including, Facebook, WhatsApp, Instagram, Snapchat, LinkedIn, Twitter, etc. to learn about the user privacy concerns and generate actionable solutions to enhance online user data and mitigate privacy concerns of individuals.
Phishing & Risk Communication
Collaborators: Dr. L. Jean Camp, Dr. Jim Blythe, Dr. Timothy Kelley, DongInn Kim, Jacob Abbott.
Phishing is the most common yet effective cybersecurity attack. I am involved in creating and learning risk communication tools which is effective in communicating risks to users by successfully catering to their mental models developed from user focused studies.
IOT Privacy and Security
Collaborators: Dr. L. Jean Camp, Joshua Streiff, Olivia Kenny, Ashley Kaufman.
IoT devices have become a part of our everyday usage. User studies focusing on the privacy concerns and understanding the security concerns of the smart devices escpecially that of smart toys are been studied.
Collaborators: Dr. Apu Kapadia, Dr. Patrick Shih, Dr. Sameer Patil, Dr. John Paolillo, Dr. Tousif Ahmed, Dakota Murray, Javon Goard, Swapna Joshi, Aehong Min, Alec Theisman.
Online interractions have increased considerably since the advent of interraction. Through this research I aim in understadning how users interract online to communicate with their audience.
Security Threats of E-Waste
Collaborators: Dr. Sadhan Kumar Ghosh, Dr. Ghazanfar Latif, Dr. Jaafar M. Alghazo, Dr. Abhijeet Das, Biswajit Debnath, Adrija Das.
E-waste has increased considerably over the last few years. With environmental concerns, security of such discarded and refurbished devices are often understudies. Our reseach provides effective recommednations to mitigate such risks.
