Privacy concerns arise naturally along with sharing or releasing personal data. Due to logical connections among individuals (e.g., online social networks) and/or correlation between individuals' data stemming from similar personal (e.g., DNA) or behavioral traits (e.g., individual mobility), privacy breaches and data holder malpractice could potentially jeopardize the privacy of many who may not even be aware of the act of sharing and its impact; not to mention consenting to the sharing. We refer to this phenomenon as interdependent privacy .
