The right to privacy under the Act

Dear Sir
After having referred to the News on BBC, I encounter a sentence like " The right to privacy under the Act". I realise that it’d have talked about the British law but I don’t really understand what exactly it include. So please would you explain it to me and or is there any website would provide the detailed information of it.
Many thanks for your help,

Best regards,

Hi Kelly,

If I am allowed to make a suggestion (I’m not ‘a Sir’ :)), I’d say that they mean
