Identity verification and authentication technologies, as one of the applications of blockchain-based solutions – and the focus of our own efforts at SecureKey Technologies – have been critical components in service delivery in both sectors due to their power to increase trust between citizens and the services they access. To convert trust into solid value added, identities must be validated through highly-reliable technologies, such as blockchain, that have the capacity to reduce cost and fraud and to simplify the experience for customers while also keeping out the bad actors. With identities migrating to digital platforms, organizations and citizens need to be able to transact with reduced friction even as more counter-bound services move to online delivery. In this article, drawing on our own experiences with an ecosystem approach to digital identity, we describe the potential value of using blockchain technology to address the present and future challenges of identity verification and authentication within a Canadian context. 10ablockchain10aconsumer privacy10acybersecurity10adigital assets10adigital attributes10adigital identity10aidentity fraud10aidentity verification10aonline privacy10aonline security1 aWolfond, Greg  uhttp://timreview.ca/article/111201672nas a2200193   4500008004100000022001400041245005000055210004900105260004200154300001000196490000600206520110800212653002701320653003001347653003101377653002001408100001401428856003601442       2013                        eng d  a1927-032100aMultifactor Authentication: Its Time Has Come0 aMultifactor Authentication Its Time Has Come  aOttawabTalent First Networkc08/2013  a51-580 v33 aTransactions of any value must be authenticated to help prevent online crime. Even seemingly innocent interactions, such as social media postings, can have serious consequences if used fraudulently. A key problem in modern online interactions is establishing the identity of the user without alienating the user. Historically, almost all online authentications have been implemented using simple passwords, but increasingly these methods are under attack. Multifactor authentication requires the presentation of two or more of the three authentication factor types: “What you know”, “What you have”, and “What you are”. After presentation, each factor must be validated by the other party for authentication to occur. Multifactor authentication is a potential solution to the authentication problem, and it is beginning to be implemented at websites operated by well-known companies. This article surveys the different mechanisms used to implement multifactor authentication. How a site chooses to implement multifactor authentication affects security as well as the overall user experience.10aauthentication attacks10aauthentication mechanisms10amultifactor authentication10aonline security1 aReno, Jim  uhttp://timreview.ca/article/716
