Patent ID: 8806590

Claim:
A computer-implemented system, comprising: a provisioning component configured to provision a secret for use with an ephemeral account prior to creation of a friendly name included with the ephemeral account, the secret provisioned prior to or at a same time as creation of the user account by a messaging service provider; a signing component configured to receive the ephemeral account from the provisioning component and to sign the ephemeral account with the secret to generate a signed ephemeral account and return the signed ephemeral account to a user of the user account; an address book of the network gateway configured to receive the signed ephemeral account from the signing component and store the ephemeral account and the secret, wherein the network gateway confirms the ephemeral account is valid when the ephemeral account is in the address book, and confirms the signed ephemeral account is signed using the secret when the signed ephemeral account is not in the address book; and a hardware processor executing computer-executable instructions that implement the provisioning component, the signing component, and the address book.
