Identity theft mitigation
Public-key authentication, based on public key cryptographic techniques, is utilized to authenticate a person opening an account. The person provides a declaration to use only public-key authentication and a copy of his/her public key to an authorized agent, such as a credit bureau. The person provides a signed request to open an account with a merchant based on public-key authentication. This merchant requests a credit report from the credit bureau, providing the credit bureau the applicant's public key. The credit bureau uses the public key to locate a credit report. Barring theft of the user's private key, the credit report will be that of the requesting user with a high probability. The credit bureau can then provide the requested information to the merchant, and the merchant can provide notification to the person that the account is authorized or not, based on what the merchant reads in the credit report.
