Respondent confidentiality is of the utmost importance within the ASA24 system. Researchers do not provide the National Cancer Institute (NCI) or the ASA24 system with any identifying data for study Respondents. Rather, Researchers specify a user ID for each Respondent and download system-generated usernames and encrypted passwords that Respondents use to access the application.
The ASA24 system also does not collect any identifying data directly from Respondents. However, IP address information is accessed for the purpose of routing information between the server and the Respondent's computer -- often the IP address is that of the user's Internet Service Provider (ISP).
IP addresses are not stored or tracked by the ASA24 system. However, logs of connections are kept for audit trail purposes. This information is not mined in any way but would be available if there were a legal obligation to release it.
