Online video search and identification service Anvato has picked up $2 million worth of a $4 million first round. Oxantium Ventures led the investment, which the Mountain View-based startup will use to launch AdMatch, its video advertising platform. The platform builds on Anvato’s fingerprinting technology, which lets publishers track the spread of their clips without the use of meta-data or watermarks.

Anvato’s entrenched and well-funded competitors include Audible Magic (which has been used by MySpace, MSFT and Google, among others), Attributor (picked up a $12 million third round in April) and AT&T and Disney-backed Vobile. Founded in 2007, the startup raised $550K in angel funding back in August. Release.
