What if you want to run a query to compare your DNA to everyone else’s to see if you have any relatives that are registered already? Wouldn’t that need access to the entire database and essentially be a point of weakness?
- WalterBright 3y agoI am no expert on such systems. But it seems to me that the comparisons should only be run within the cells. The caller only passes the one to compare it to, and the only thing that comes back from each cell is any matches. That way, only the specific cell has access to its data.
