The transformation of EVVE will make it easier for businesses and government entities to verify birth and death records and prevent identity theft, Cognizant said in a statement.
The company will also help the National Association for Public Health Statistics and Information Systems (NAPHSIS) grow its customer base by enhancing its marketing strategy and attracting new subscribers, it added.
This will enable NAPHSIS to not just expand the usage of EVVE across federal and state agencies, but also make it available for the first time to authorised non-governmental organisations with proven administrative use or property right to query birth and death data, Cognizant said.

The improved EVVE will match queries against 250 million birth records in participating vital record databases nationwide.
By using a single interface, subscribers will now be able to verify the validity of a paper birth certificate or request an electronic certification in lieu of the paper birth certificate.
The system will also prevent fraudulent acts by flagging if the person matched is deceased, while also providing for the electronic verification and certification of death records.
