Perspective Project Notary Information
The Perspectives Project notaries monitor over 350,000 remote sites twice daily. The notaries are diverse in terms of geography and upstream service providers. Most notary servers are scattered across the United States, but the set includes a server in both Asia and in Europe.
Your privacy is important to us. All network notary servers adhere to a strict policy of never recording client IP addresses when a client performs a notary look.
Additionally, the Firefox client lets you configure the scenarios when the client should contact Notaries. In fact, you can set the preferences of the Firefox client to ask permission each time before contacting notaries.
