The author illuminates the landscape of online threats and scams associated with Aadhaar, exposing the sale of data on websites and unauthorized access to personal information. Cases of unmatched biometrics and the exploitation potential within job-seeking platforms highlight the necessity for enhanced vigilance and stringent security protocols. The book offers an exhaustive exploration of Aadhaar's profound influence on India's identity domain. Balancing the acknowledgment of its merits with a candid exposure of pitfalls, the book presents a nuanced perspective on the complexities of Aadhaar. Real-life examples and critical analyses contribute to a comprehensive understanding, prompting essential questions about privacy, security, and the evolving dynamics of biometric identification in the digital era.
