Ensuring Participant Privacy | ||||
|
Participants are not required to provide their name or other identifying information. Data are only accessible to the principle investigator, password protected, with 256-bit SSL encryption. Participants entering the $100 lottery will need to provide an e-mail address, which is not linked to survey data. We do not use web "cookies" to track users. We identify multiple responding by logging browser type and a partial IP address (dropping the last digit), to preserve privacy. |
