When developing electronic systems, there are some industry standards requiring United States agencies to ensure the transactions provide an appropriate level of assurance. Generally, servers adopt the US' Office of Management and Budget's (OMB's) E-Authentication Guidance for Federal Agencies (M-04-04) as a guideline, which is published to help federal agencies provide secure electronic services that protect individual privacy. It asks agencies to check whether their transactions require e-authentication, and determine a proper level of assurance.[16]
