We have some clues:

1. Dark skin

2. Blond hair

3. Prisoners of War code ( When Barry Allen was captured by Zoom on Earth 2, he was placed in a cell beside Jesse Quick and the man, who wore a mask, and was always knocking on the carbyne of his cell.  Barry and Jesse eventually realized he was not using Morse code, but a 5x5 tap code commonly used by POW's. The two began to work together and started to decipher his message. Barry and Jesse discovered the first part of his message spells J-A-Y as in Jay Garrick.)

4. Zoom says "you won't believe me if I told you" Since Zoom was able to bring a younger version of him from the past, the masked man can be from the past, present or future.

Future: Barry and Iris son (Don Allen) or John Diggle son (Connor Hawke who we saw in the Legends of Tomorrow episode 'Start city 2046' as the new Arrow)

Past: Joe West (younger version)
