Metapho_borderedHere’s one for the iOS users out there concerned about information security issues! I just discovered the app Metapho, which lets you view the metadata associated with the photos on your iOS device. More importantly, it lets you choose to share images without metadata, while maintaining the metadata locally. How does it do that?

It uses iOS 8’s new extensions feature to make itself available in the universal share sheet as a destination for photos. Choose it, and it gives you the option to share it further without metadata. Metapho makes a quick edit in the background, shares the photo to the next program (Twitter, Facebook, SMS, Mail, whatever) without any of the associated metadata, then keeps the file with metadata in the photo roll. So you get all the benefits of sharing photos, without the infosec leaks. I’ve tested it, and it seems to work just like it says.


I’m impressed, and happy to see iOS apps that are focused around giving people control over their data in ways that may not be obvious to most users. Metapho is free to download and view your metadata, $1.99 in-app purchase to enable removal and the share-sheet ability.


Social Cataloging

A great presentation by Tim Spalding called What is Social Cataloging?, from the LIANZA 2009 conference in New Zealand. I recommend it if you’re at all interested in metadata, LibraryThing, or, I suppose, Tim Spalding.

Concluding Keynote at LIANZA 09 in Christchurch, NZ. Covers LibraryThing, tagging, personal cataloging, sharing, social networking, implicit and explicit social cataloging, collaboration, what’s wrong with OCLC and other exciting topics.
