Why Free Registrations Get Abused
When an event features limited seats or merchandise giveaways, students often fill out forms multiple times under fake emails or friends' roll numbers to hoard passes.
Enforcing Strict Uniqueness - **Institutional Domain Restriction**: Restricting registration to `.edu` or university domain emails (`@iitb.ac.in`, `@vitstudent.ac.in`). - **Composite Unique Keys**: Ensuring (Event ID + Student Email) and (Event ID + Roll Number) are unique in the database prevents multiple claims by the same individual. - **Dynamic Cryptographic Signatures**: Spark signs ticket QR codes using HMAC-SHA256, rendering forged screenshots unreadable by volunteer scanners.
