Soon, new system that uses plant DNA to prevent cheating in exams

January 26, 2012 - Washington

A firm has come up with a new system that uses molecules of plant DNA to validate a student's identity and thus thwart testing fraud.

According to Dr. James Hayward, president and CEO of Long Island-based Applied DNA Sciences, Inc., the "absolutely unbreakable" system features a counterfeit-proof identification card that combines the embedded DNA info with an authentic photograph of the student and forms a one-two identity verification that is impossible to forge or borrow.

"We start with the whole genome of a plant and it doesn't matter which one," Fox News quoted Hayward as saying.

"Plants are a great choice because they have quite complex DNA, in some cases as complex or more complex than humans and they also have systems that enable them to endure stressors we don't normally expose humans to."

Once implanted into the card, Hayward said that the "digital DNA" is then scanned using a smartphone and sent wirelessly to a secure database in a private cloud.

"We're capable of designing, in effect, an infinite number of markers, and we're able to embed those markers and encrypt it into a variety of media," he said.

"It eliminates the potential for electronics to be counterfeited. In order to crack our DNA sequence, you'd have to know the sequence and that cannot be uncovered from the marker itself," he added.
