Hi all, I had an idea for an anonymous PGP messaging board system and wanted to get feedback on it or know if this idea has already been done.
In short, this would be an anonymous messaging system where you can post encrypted messages. Anyone can access the encrypted message but obviously only the one with the private key can decrypt it. Receiving users can filter for messages by their key ID to see if they have received anything. The system also replicates data across multiple servers so you can post a message on server A and a user can view the message on server B. Problems this solves: * Increase anonyminity of the *sender*. No attributable data is stored for the sender, such as email headers or IP addresses. The receiver can take steps to be anonymous, such as using a different key than a primary, but ultimately the receiver will require some form of a unique identifier. * While you can already do this on a message board or Usenet, those systems are not designed for this. They are not easily searchable or centralized. For example, I cannot filter for all messages sent to 0x0123456789ABCDEF on an online forum without a manual effort. The general process of the server would be to receive a message via HTTPS, determine its key ID, store it in a binary format to reduce the size and make it searchable by the limited metadata in all encrypted messages. Finally, two or more servers can replicate data on a periodic or in-real-time basis. And there are obviously standard problems, such as spam, the size of the database or a rogue server storing sender IP address data. But these are standard problems in all such systems. Obviously this would not be the next big method of communication, but an interesting niche idea and it seems easy to produce a proof-of-concept. Thoughts? I full anticipate being torn down :) --- Farhan Khan PGP Fingerprint: 1312 89CE 663E 1EB2 179C 1C83 C41D 2281 F8DA C0DE
