BEIJING, Aug. 20 -- Israeli scientists have developed a new technology to fight biological identity theft, according to media reports Thursday.

The researchers showed that with the use of basic equipment and know-how, anyone can obtain artificial DNA. The standard technique called whole genome amplification.

Researchers also demonstrated how one could implant DNA into real blood by using a centrifuge to separate red and white blood cells and placing the DNA in the former, giving the blood a new profile.

As part of the experiment, a sample of the modified blood was sent to a laboratory in the United States that works with FBI forensic teams, which failed to catch the forgery, researchers said.

To combat the practice, researchers have developed a DNA authentication method that distinguishes between real and fake samples.

The new process was tested on natural and artificial samples of blood, saliva and touched surfaces, with complete success, researchers said.

It also identified "contaminated" DNA that had been mixed with two or more samples.
