1. Government mandates everyone to have Aadhaar card . In Aadhar card application form, there is option towards "sharing of data with third party" . Most People do tick that option. If they don't tick,there are chances that officers(mostly in bank where they take photo and biometric details of applicant) themselves tick that and apply for aadhar card.

2) Many colleges sell Students' Info, Phone number, Address for money. We get direct calls from coaching centre who didn't at all had our phone number.

3) When you buy something (say Domain name in Indian company),there are chances that they sell your information across many corporate interests without your consent.
