Behavioral Biometrics
I believe that the usage of behavioral biometrics is inherently unethical. The large-scale storing and usage of personal behavioral data not only violates personal privacy, but sets a dangerous precedent of the amount of involvement and knowledge corporations and governments can have of a person’s life. As has been repeatedly demonstrated in recent years, both governments and corporations can and will abuse access to people’s data in any way they can. See: Snowden, huawei.
I also believe that the sharing of any stored biometric data with the government is unethical. Governments the world over have proven themselves untrustworthy and unethical when it comes to personal data, therefore, giving them more access would be unethical.
Usage of biometrics is absolutely an invasion of personal privacy. Even with user consent, the amount of knowledge that can potentially be gained is disturbing. The collection of personal data tends to be a violation of personal privacy in general, even when behavioral analysis does not come into the equation.
