A New York judge has said Kanye West's lawyers can do the research necessary to learn the identities of the creators of digital currency called Coinye West.

US District Judge Analisa Torres granted the Gold Digger rapper's lawyers the legal authority to learn who'll face a lawsuit saying the electronic currency was created to cash in on his fame.

The lawsuit was filed this week in Manhattan federal court and seeks unspecified damages.

The judge said there is a likelihood Kanye will succeed with his claims. She said the music star's lawyers were told by Coinye West website operators they are anonymous and will keep it that way.

One of the websites targeted by the lawsuit put up a message after the lawsuit was filed saying: "COINYE IS DEAD. You win, Kanye."
