Hi there,

I am curious about one particular aspect of eMule. Unlike Torrents-like P2P, which rely heavily on external middlemen-trackers, eMule has an in-built search engine.

Now lets say I have a bunch of photos (primarily in *.jpg or *.png ) metatagged by IPTC or MWG with the use of ExifTool. The content of my collection can be sensitive to copyrights claims. Imagine that I wanna share my collection with someone else, so a person could search my collection remotely by metatags and retrieve the images without disclosing neither mine, no its own identity. Is this something eMule can help to facilitate?

Thanks in advance for guidance.

That would involve a whole lot of additional code to examine each file metadata and store it, for it to be searchable. You would have to extend the protocol and then interoperatability would suffer. One of the eDonkey variants might want to explore this however.

Thanks. And that is still not the worst part of it. Metadata can be subject to frequent changes (tags updates and deletions), which results in re-calculations of hash values for each file.

There is also problem with fake metadata (a picture portraying a pet can be tagged as "lion" or "Jupiter"), so in order to ensure the validity of the shared content users would need to have some sort of rating system (perhaps separate ratings for owners and each piece of their collection too). While some a*s-h*les may still spoil it by upvoting the fakes once in a while. So unless image recognition and tag assignment are fully automated (by using advanced OCR engines and machine-learning) I doubt we'll see an effective solution any time soon.

There have been literaly dozens and dozens of publications in the last 20 years, if one googles by keywords "Searching in peer-to-peer networks" or "Content-Based Image Retrieval", but they still bring us nowhere.
