Yesterday, the Senate Commerce Committee questioned former Yahoo CEO Marissa Mayer, Verizon chief privacy officer Karen Zacharia, and both the current and former CEOs of Equifax on how to protect consumers against major data breaches. The consensus was that Social Security numbers have got to go.
Multiple times throughout the hearing, Brazil’s Infraestrutura de Chaves Públicas system of citizen IDs through digital certificates came up as a potential model for the U.S. as it moves forward. In this model, a certificate lasts for three years at maximum and can be used to issue a digital signature much like written signatures are used now. Unlike its counterpart in the U.S., these identity accounts can be revoked and reissued easily through an established national protocol.
