The subsequent 4G internet revolution accelerated internet accessibility, fostering the establishment of new technologies and companies enhancing user experiences. E-commerce flourished, with cloud-based entities, reshaping consumer preferences towards online shopping. This paradigm shift comes with challenges. As online transactions surged, data became the cornerstone sought by companies for feedback and analysis. This led to a complex scenario with vast data storage across companies, posing security risks from potential hackers. In the past decade, hacking incidents exposed customer data, risking privacy and well-being. Despite enacted legislation, success, especially in India, remains elusive.
