Significantly, human rights implications of data collection and exchange may be different, depending on the purpose for which such measures are undertaken. In this regard, the chapter briefly reviews key human rights that may be impacted by data collection and exchange.

As all human rights are interrelated and indivisible, impacts on one right have implications on the enjoyment of other rights. The right to privacy 207. The right to privacy428 is regarded as a foundational aspect of democratic societies. The violation of this right has an impact on numerous other human rights, including the right to life, liberty, security of person, health, work and social security, among others.429 One of the greatest risks of collection, use and exchange of personal data is the potential infringement of the right to privacy, which is provided under a number of international instruments, including the Convention on the Rights of the Child.430 The Convention requires States parties to protect every child from arbitrary or unlawful interference of his or her privacy in the home, family and through correspon- 428 “Privacy” has been defined as “the presumption that individuals should have an area of autonomous development, interaction and liberty without interaction with others, free from State intervention…” A/HRC/23/40, para. 22; A/HRC/13/37, para 11, both citing Lord Lester and D.
