Because it may be near impossible to keep genetic information private, some researchers are calling for the creation of centralized database with tight access controls, Bloomberg Businessweek reports.

DNA databases, it notes, have helped arrest individuals in a number of cold cases, including the Golden State Killer case. Investigators have used the GEDmatch database in similar cold cases, and FamilyTreeDNA has said it has provided the US Federal Bureau of Investigation access to its database.

"There is an urgent need for additional regulation of government access to the genetic information housed in public and private DNA databases.
