Is it ethical to use biometric identification data for purposes of daily living like paying in a supermarket or for identification at airports? What guidelines would have to be in place to ensure that such everyday applications of biometrics are ethical?

How should the rights of the community (public health) be balanced against the rights of individuals? Should public health data use be subject to different ethical standards than the use of individual medical data?

Should international sharing of biometric and medical data be harmonised? Who should have the authority to oversee this process?
