"I have a problem with how they are to validate information," Binney, a veteran US government cryptanalyst, told Sputnik.
The blog post said the company was making the Fact Check label in Google News available everywhere and expanding it into Search globally in all languages.
Only publishers that are algorithmically determined to be an authoritative source of information will qualify for inclusion, the statement added.
Binney expressed concern about Google’s condition.
"It causes me a big problem. For example, if publishers from MSM [mainstream media] are included then I see problems right off the bat," he stated.
The snippet will display information on the claim as to who made the claim and the fact check of that particular claim, Google said in its post.
However, Binney said Google had yet to demonstrate they had a transparent and credible process to make that distinction.
"Somewhere they need to distinguish between opinion and documents that could stand up in court. I don't see where they have established a validation process," he cautioned.
William Binney, a cryptanalyst and mathematician, served for 30 years as senior analyst at the National Security Agency (NSA). He is known for exposing major aspects of NSA’s blanket surveillance programs.
