The answer is because he is a programmer a graphic designer. So he likes hacking as you can guess from many of his videos and hackers masks their faces. Watch dogs was the first thing that came to my mind when I saw his first video.

If you compare the character in Watch Dog and Alan Walker you gonna find lots of similarities even the logo is somewhat similar.

Moreover when asked in an interview by NRK, why he used the mask, he said: "It is to keep a low profile while maintaining the public image they have given me. I think it's pretty cool. A little twist that makes people ask themselves questions about who really is the person behind Alan Walker.", and applied: "Basically, all of the data-world, focus on anonymity. Anyone can join Alan Walker, and the masks show that they can be anyone.

In the first promo pictures his management handed out, Walker's face was barely visible at all. Also in the music video for his single "Alone", he is all dressed as a black shadow figure. This is, according to the artist himself, a carefully planned image drawn up together with the record company Sony. "In a meeting with them we talked about how we could build the profile of Alan Walker", said Walker to the newspaper VG. "They asked about my interests. I replied PC, computer gaming and stuff like Anonymous and computer hacking where hoodies play a role.

At a press conference 9 November 2016, Alan said: "The concept with the mask is very cool, that is inspired by the hacker group "Anonymous" and the television series Mr. Robot. I have a background as a gamer and kept on with it before I started with music. By taking on a mask I can be immediately seen as a gamer.

"A lot of people ask me why I am wearing a mask. The mask is more of a sign and a symbol of unity and being alike each other, rather than me being different." said Walker, behind the scenes of the single "Alone".
