Charles Stross has a nice blog post up about the UK DNA database, database security, and the ever dropping price of gene sequencing and replication. The UK has a government DNA database of anyone ever booked by anything by the police. Because of how these things work, lots of entities have access to it for good reasons. Like the US No Fly List, being on it is seen as a black mark on your trustability. He posits some scenarios for injecting data into the DNA database through wireless and other methods.
Another thing he points out is that the gear required to reproduce DNA is really coming down in price. In the not too distant future, it is entirely possible that the organized criminal will be able to plant DNA on the scene of a crime. This could result in pranks ("How'd the Prime Minister get to Edinburgh and back to London in time to jiz on a shop window?") to outright frame jobs.
Which is to say, once DNA reproduction gets into the hands of the criminal elements, it'll no longer be a good single-source biometric identifier. Presuming of course that the database backing it hasn't been perved.
