protection on the web

The news that I got to see it on a law which was implemented in companies that have or give a web service example (facebook) in which this law stated that the owners of these domains will have to put protective filters the web pages where the information is automatically encrypts personally it's a law something good to a certain point because they handle the information so users will be protected and only the sender will be the only one able to see and a choice Beuna for security.
