Does providing a secure online survey link guarantee complete confidentiality of responses?

• A. Yes
• B. No
• C. It depends
• D. Not applicable

Answer: (C)

Confidentiality isn’t guaranteed by simply giving someone a secure online survey link. A secure link helps protect data in transit, but many other factors determine whether responses remain confidential. The best answer reflects that it depends on how the study handles data overall: what information is collected, whether data are de-identified, how data are stored and who can access them, the security of the survey platform, how data are transmitted and stored, and what is described in the participant consent and data management plan. Even with encryption and secure access, risks like potential re-identification, data breaches at the platform or server, and whether IP addresses or other identifiers are collected can affect confidentiality. So, you cannot guarantee complete confidentiality just from providing a secure link; it depends on the broader data-security and privacy practices in place.
