Parents who share pictures of their children on social media are putting their human rights at risk, the United Nations has warned. 

The UN's special rapporteur Joseph Cannataci said that "strong guidelines" were needed to preserve the rights of children whose parents upload video and images of them.  

During a mission to the UK to assess the privacy situation he also found that kindergarten-age children were being surveilled using CCTV at school and in their bedrooms.
