Do embedded rights metadata of photos survive social media systems? Michael Steidl, IPTC



welcome to this short presentation about something very real so it is about a simple workflow of metadata in photos which are embedded into photos and if this workflows goes across social media systems so a quite usual workflow is simply to write this up so you're taking a photo then metadata are added and you see on the very few metadata actually in most cases only the date and time when the picture was taken is already embedded into the metadata at the moment when taking a photo so there is an effort you the photograph for the agency has to spend some time on adding the method metadata to it and to embed them that means there must be a good reason and the good reason is to describe the photo but also to claim some rights relevant information that means who has the copyright who is straight creator and also some usage terms mostly in the in the copyright notice okay so when this has been done you spread this to other parties so if you look at this this is how it usually looks like you forward your photo to some distribution system and then your photos go to some receivers and users okay that's the simple case the more elaborate cases you embed metadata I've shown this as simply the word metadata in the slide and so this is the intention the metadata go with the pixels so you don't have to move this separately you don't distribute the separately and even as this has been mentioned today if you have an identifier for a photo which should go which represents an entry in the registry this also has to be embed and therefore is some kind of metadata which is embedded into this photo okay so how does this work now with social media systems so you upload a photo to the social media system and then you have two opportunities to make use of it well the first opportunity is I think from many people this is sufficient to share it with other for viewing so they would like that others have a look at this but we have to be real people and not naive and say okay at the moment when mitch is shown on a webpage in most cases you can save it as an image file so the browser's provide their menu feature which lets you if you see a photo you click on it and then you open the context menu and say safe as there are a few systems we found out which prevent doing this we which disable these features but many systems allow what the browser enables you to do and the second opportunities there are some social media systems which have an explicit download feature that means there is some wear a button there is somewhere a list of men you like items what you can do with the image and this includes there such a download feature okay so what we have tested now is simply that we said okay let's see what happens in this work of workflow going through so the first test is we have looked at what has been uploaded our metadata are shown on the user interface and if they are shown are they shown correctly that means is there a label which indicates for instance this photo was taken by a person or party and is this the value of them that metadata all the dates created okay secondly we checked if there are four relevant fields are shown that are the copyright field credit create the field and the caption description field and then as explained before we try to save as or to download an image and when it has been saved on a local computers or not in the system but on a local computer we looked into the image file and check their art they're still embedded metadata so technically they're in headers embedded and so let's see other still in the headers and better the results we found there so we followed a traffic light indication so green means everything is okay yellow means not everything is ok but it looks not so bad and red means yeah to be a sorry to tell but that looks bad so you see there we have their 1515 social media systems we checked and there you see the results so they are quite mixed there are some which have a long line of greens lights but others also have a long line of red lights that means they're particularly in this section here that means if you download an image the metadata organ they are not embedded anymore so you see that the results 45 front pic so there is simple in lexical order so you see Facebook and Flickr here they could perform better hooghly does quite well we have tested large and small ones so we went try to find out which are quite common in this area so we have the image lead to male photobucket picked if I Pinterest is more widely used and the grey means there was no possibility to test this because either you cannot download or you cannot save as an image or if it's displays correctly if nothing is displayed we cannot say correct or incorrect ok by the the second group and that's the third group so tumblr more widely used system quite well Twitter ok metadata Oregon yfrog better so you may ask can I look at this elsewhere ok you can do so if you go to the embedded de todo dork side so this is a distinct site but it's managed by diabetes see because it's the home of them embedded metadata manifester which encourages both photographers to embed metadata into the images but also encourages systems which are using these photos to keep them in and not to stretch them out thank you
