Partial Homomorphic Encryption

Allows certain operations on encrypted data, like addition. Useful for encrypted voting systems, where votes are counted without revealing individual choices.

Somewhat Homomorphic Encryption

Allows limited operations (e.g., certain additions and multiplications) on encrypted data. It could be used in secure data aggregation for outsourced analytics where partial data processing is needed.

Fully Homomorphic Encryption

Supports arbitrary operations on encrypted data, allowing complete computation without decryption. For example, encrypted medical data can be analyzed without ever decrypting it, preserving patient privacy.
