Introducing Elog.io

Commons Machinery is introducing Elog.io, a new catalog of creative works in which users can find the author, license information and source of images. The catalog can be implemented in other software, or used with browser extensions for Firefox and Chrome, to look up information about images posted online, even when images are posted without […]


How does Elog.io relate to dating & viral images?

When we started to research into the area of reverse image searches, we discovered that one of the drivers for reverse image search is: dating sites. Not the dating sites themselves, but the visitor thereof. It appears that fake profiles are quite common, and a fake profile needs a fake image, usually from Google Images […]


Pre-alpha sneak peek at elog.io…number two!

In this preview of our elog.io plugin, we demonstrate how it looks up information in our catalog (containing information from Wikimedia Commons) to provide automatic attribution into LibreOffice or any other application supporting pasting with HTML.


Pre-alpha sneak peek at Elog.io Firefox add-on!

In this video, our founder and CEO Jonas Öberg walks us through a pre-alpha version of the Elog.io plugin for Mozilla Firefox. The Elog.io catalog is currently seeded with information about 10,000 images from Wikimedia Commons, and the Firefox plugin can match images seen on other web sites with images from the catalog, meaning you […]

The iPhone 6 and copying data to the cloud

Unless you have been living in a completely isolated monastery, you are probably aware that the iPhone 6 was released on the 19th for general public sale (and the very first purchaser, a guy in Perth, Australia, dropped it while being interviewed on camera). Here in Montreal, a quick walk by the Apple store around 7pm […]

Updates on Elog.io!

When creative works – images in particular – are shared and used online today, they frequently lose their connection with the original. Even only one share often makes it impossible to find out where an image came from, who created it, or what permissions someone has to use it. What license is it released under…and […]

The New Generation of Trash Pickers

By now everyone knows, or should, that anything on the Web is susceptible to misuse or abuse. Personal information (such as social security numbers and credit card information) should not be posted to untrustworthy sites. With people relying more and more on digital media, internet fraud and identity theft are on the rise. This is […]


Digital image matching, part 2: finding similar hashes

Last week, Artem described our implementation of blockhash for image matching. The second part of making this into a service that can find similar images is to search for hashes that are close but not always matches. To do this we have implemented an algorithm called HmSearch[1]: C++ library and command line tools Node.js package […]

Laughing or crying at Le Corbusier: Every action has consequences

Le Corbusier is one of those names: many have heard of him but few know why. (This is based on a totally unscientific poll I took at a party. It reflects the poor quality of knowledge among my chosen friends, and bad science on my part to generalize it in this way) Anyway, we vaguely […]

Digital image matching, part 1: Hashing

One particularly interesting planned Elog.io feature is matching images found online with the catalog, which in turn makes it possible to retrieve metadata by comparing image contents to the records in our database. This, for instance, allows looking up metadata instantly from the browser when we see an image on the web. After some explorations […]
