Protect and Index Sensitive Data with Polymorphic Encryption

https://www.linkedin.com/in/toanshu What if you could run real-time queries on data that remains safely encrypted? That might seem nonsensical at first — doing anything with encrypted data is usually cumbersome, resource-intensive, and slow. But real-time queries on sensitive data aren’t just possible, they’re very practical, especially when working with sensitive personal data (PII).

Homomorphic encryption is widely considered to be the “gold standard” of encryption because it supports arbitrary operations on encrypted data without first decrypting it.

Polymorphic data encryption is distinct from polymorphic key encryption, in which encryption keys rotate, but data is unusable unless you fully decrypt it.
