EMC today strengthened its already strong grip on the identity market with the acquisition of knowledge-based authentication provider Verid.

Terms of the deal were not disclosed.

Verid, whose solutions are used on websites, back-office systems and interactive voice-response platforms to validate users’ identities, will join EMC’s RSA Security division.

Last June, EMC acquired RSA, best known for its tokens and smart cards, for about £1 billion. Before that deal, RSA picked up strong authentication provider PassMark, known for its SiteKey login tool, and Cyota, which offers banks and other financial institutions fraud intelligence.

"The acquisition of Verid both builds upon our existing set of authentication methods and significantly expands our capabilities into the preliminary vetting and verification stages of new user relationships in a variety of markets," Christopher Young, vice president of consumer and access solutions at RSA, said in a statement today announcing the acquisition.
