First spotted by a Spanish-speaking blogger identified as Kwisatz, the photograph showing three men is tucked into one of the holograms on the surface of Vista DVDs. But at just one millimeter in size, it's too small to see without magnification.
"These security measures were never intended to be impossible to find, but rather difficult to reproduce," said White.
Microsoft stepped up the DVD antiduplication measures used for Vista and embedded numerous holograms in the plastic. "While it's extremely difficult to replicate a holographic design in general, the inclusion of original images makes it that much more so," White said.
There's one mystery still unsolved, however: White did not name the three tiny Microsoft employees.
