Encrypting research data

Encryption is a method of protecting sensitive research data by turning it into an unreadable code that only people with special passwords or keys can view.

Researchers may be required to encrypt sensitive research data to meet legal, ethical, and contractual requirements. This may be important when you are sharing or storing data to protect participants' privacy or to follow best practices in your research discipline.

FileSender and Globus both offer encrypted file transfers. See Choosing data transfer services.

Encrypting files on a University-managed device or a University virtual machine provides additional security. There are several methods for encrypting files, including:

• Built-in tools: Windows and macOS have built-in options to encrypt individual files and directories using your user account.
• Microsoft Office encryption: Using Microsoft Office common file types, such as .doc, .xlsx, and .ppt, you can save files as encrypted, password-protected files.
• Creating a secure archive: Archiving software lets you create password-protected, compressed archives of files and folders. Examples include 7-Zip and WinZip, which are available in the Software Centre. It is often more efficient to package multiple files into a single .zip archive before sending them over FileSender.

Note: Use strong passwords when encrypting files. If a password or key is lost, then it is impossible to recover encrypted data.
