As more people handle tasks that require personal verification online, digital signatures are increasingly important.

Arcot Systems, which does digital-based signatures has raised a second round of funding. The money will no doubt be used to expand its operations in digital authentication.

The $23 million round was participated in by Accel Partners, Goldman Sachs, ONSET Ventures, Granite Ventures and Vedanta Capita.

The Sunnvale, Calif.-based Arcot Systems recently developed a token that Google can give business users of its online application suite so they are more secure.
