How does Field Encryption work?

Managing encryption permissions

Create a bespoke permissions framework by giving your users separate rights for encryption and decryption, per institute.

Castor Forms

Integrate encryption into your study

While building your study forms, you decide which fields require an additional layer of protection, and therefore should be encrypted.

Encrypt data upon collection

Data is encrypted automatically upon collection, ensuring that data visibility and exposure is kept at a minimum.

Search encrypted fields

Encrypted data can be searched only through an exact match, to ensure privacy and prevent attempts to uncover participant identity.

View the encrypted data (decrypt)

Add permissions for your data monitors so they can easily search and complete source data verification (SDV) using PII on your patients' health records.
