Thanks to companies like 23andMe, this won't be neccessary in the future. If enough of your relatives have sent their genome to those companies, they already have the sequenced genome as well as consent from your relatives to use their DNA. Their DNA is highly similar to your DNA which means that they can extrapolate to you, without even having to resort to covert methods.
