That concern is more and more being voiced under the phrase “the ethics of analytics”.
We realize that we have more possibilities for not only amassing personal information but for generating, through aggregation of the information received, an even more specific profile of a person. We realize that we truly need to have an ethical framework for that.
As we discover new models for, say, energy rates and the consumption of electricity, we realize that some people would actually like to have billing tailored to their personal consumption, which could reveal very personal information about usage. Combined with other information, it could actually draw a rather intrusive profile of an individual. That needs to be addressed, absolutely, through a proper ethical and legal framework to ensure that the principles of privacy we still adhere to—even in this new context of information technology—are respected.
