There are many occasions where conflicts can arise between protecting users’ data and providing online security.

In some cases, for national security reasons, the deletion of data can be ordered by national authorities and might be interfering which the right of expression. But which are the limits of this control? And what are the rights of the user of being notified of such measures?
Similar concerns could be raised for what concerns the use of personal data made by private companies, and the correspondent rights of users to know/act on this regard.
Lines are sometimes difficult to draw. Have you in mind examples of conflict between security measures and the respect of human rights? Can you list some of those?
