Architecture for generating a temporary account (e.g., an email address) with a user-supplied friendly name and a secret used to the sign the temporary account. For example, when a user wishes to create a temporary email address to use with an online organization, a friendly name is provided and the system generates a temporary email address including the friendly name. A signing component signs the temporary email address with a secret. One or more of these secrets can be provisioned prior to the user's creation of a friendly name, which eliminates propagation delay. During use, only incoming email messages having the temporary email address signed with the secret are validated. When the user revokes the temporary email address, the secret is revoked and the revocation is propagated to network gateways, rejecting any email sent to that address.

Signed ephemeral email addresses

Multiple contacts are aggregated through contact linking into a unified profile view addressing conflicting data, duplicates, etc. By persisting contact information in a server-maintained mailbox that is used as a storage model and as the contact linking system, roaming solution across form factors (mobile, slate, PC, etc.) can be provided with higher accuracy and fewer false positives. By centralizing the solution in the mailbox, redundancy and manual work by the user is substantially reduced. Contact data, communication heuristics, corporate directory meta-data, instant messaging data, etc. can be leveraged in linking contacts.

Persisting contact information in mailbox

Systems for providing sign-up email addresses are disclosed herein. A user may set up a sign-up email address for receiving emails from a trusted, Internet-based enterprise. The user may set up a dedicated mailbox folder associated with the sign-up email address or enterprise. The email server may automatically direct emails coming from that enterprise into that folder. To 'unsubscribe,' the user needs only to delete the folder or the sign-up address. Emails from the enterprise to the sign-up address may be highlighted in the user's main inbox. Thus, the user may be assured that any such email is truly from the enterprise, and not a phishing expedition or spam. Such systems also provide the user with effective tools to recognize phish or spam emails that appear to be from the trusted enterprise and not to act on them.
