Facebook Track Photo Download
Sibyl Piccuillo
Facebook has become synonymous with privacy violations in the year since Cambridge Analytica came to light. Now in the same week that details of the record $5 billion FTC fine emerged, an Australian cyber researcher has reopened a years-old debate as to whether the social media giant is embedding "hidden codes" in photos uploaded by users onto the site.
"Facebook is embedding tracking data inside photos you download," Edin Jusupovic claimed on Twitter, explaining he had "noticed a structural abnormality when looking at a hex dump of an image file from an unknown origin only to discover it contained what I now understand is an IPTC special instruction." The IPTC (International Press Telecommunications Council) sets technical publishing standards, including those for image metadata.
Jusupovic described this as a "shocking level of tracking," adding that "the take from this is that they can potentially track photos outside of their own platform with a disturbing level of precision about who originally uploaded the photo (and much more)."
According to one analyst, the metadata has been added since 2016 and "contains an IPTC block with an 'Original Transmission Reference' field that contains some kind of text-encoded sequence. This coding method lets Facebook "know it has seen the image before when it gets uploaded again," explained a user on Reddit. "It is yet another way to learn associations between people. Person 1 uploaded a bunch of the same photos Person 2 uploaded, let's show them both all the same advertisements!"
Another user on the same forum linked the coding to the current focus on the spread of fake news: "You download a meme from some account/page which is known to spread propaganda/hate speech etc. Now you think, hey let me just share this on WhatsApp on my family groups, because why not. Now, Facebook can easily tag you as a user who 'believes in that propaganda' and can sell that data to political parties or companies to target ads or more propaganda on you."
Not everyone is willing to play along with the Facebook scheme though. Twitter strips out the basic level of IPTC coding when images are posted on its site. But what remains unknown is whether there are other levels of more advanced steganography (hidden data in media) used by Facebook. There are continual advances being made in hiding data in images, some for security and data protection, others to execute advanced levels of malware that can be virally shared across social media platforms.
Jusupovic told me he thinks "this is likely just the tip of the iceberg, this particular discovery was very obvious and easy to find. But in the future, it will be easier for companies to hide these sort of privacy violations. There is an emerging field in steganography, which will continue to be a problem and will be much harder if not impossible to spot."
You'd need to create a custom Facebook application that grabs user information based on the Facebook open graph for this. Users will have to allow your application to access their data first though. there is no way to track user information simply by uploading a photo on your wall/photo albums
The like button on the social networking website Facebook was first enabled on February 9, 2009.[1] The like button enables users to easily interact with status updates, comments, photos and videos, links shared by friends, and advertisements. Once clicked by a user, the designated content appears in the News Feeds of that user's friends, and the button also displays the number of other users who have liked the content, including a full or partial list of those users. The like button was extended to comments in June 2010. After extensive testing and years of questions from the public about whether it had an intention to incorporate a "Dislike" button, Facebook officially rolled out "Reactions" to users worldwide on February 24, 2016, letting users long-press on the like button for an option to use one of five pre-defined emotions, including "Love", "Haha", "Wow", "Sad", or "Angry". Reactions were also extended to comments in May 2017, and had a major graphical overhaul in April 2019.
The like button is one of Facebook's social plug-ins, in which the button can be placed on third-party websites. Its use centers around a form of an advertising network, in which it gathers information about which users visit what websites. This form of functionality, a sort of web beacon, has been significantly criticized for privacy. Privacy activist organizations have urged Facebook to stop its data collection through the plug-in, and governments have launched investigations into the activity for possible privacy law violations. Facebook has stated that it anonymizes the information after three months, and that the data collected is not shared or sold to third parties. Additionally, the like button's potential use as a measurement of popularity has caused some companies to sell likes through fake Facebook accounts, which in turn have sparked complaints from some companies advertising on Facebook that have received an abundance of fake likes that have distorted proper user metrics. Facebook states in its Terms of Service agreement that users may only create one personal page, and it has ongoing efforts against the spread of fake accounts.
The like button is a feature of social networking service Facebook, where users can like content such as status updates, comments, photos and videos, links shared by friends, and advertisements. The feature was activated February 9, 2009.[2] It is also a feature of the Facebook Platform that enables participating websites to display a button that enables sharing the site's content with friends.[3]
When a user clicks the like button, the content appears in the News Feeds of that user's friends.[4][5] The button also displays the number of users who liked each piece of content, and may show a full or partial list of those users.[6] The ability to like users' comments was added in June 2010,[7] and the ability to react with one of five pre-defined emotions, including "Love", "Haha", "Wow", "Sad", or "Angry", was added in May 2017.[8][9]
After more than a year in testing,[11] which included October 2015 availability in Ireland and Spain,[12] Facebook officially rolled out "Reactions" to users worldwide on February 24, 2016. The feature allows users to long-press on the like button to get options between five pre-defined emotions ranging from "Love", "Haha", "Wow", "Sad", and "Angry".[11][13] In June 2017, in celebration of Pride month, Facebook introduced a rainbow flag as part of its Reactions options.[14][15][16]
The design of the reactions was updated in April 2019, with more frames comprising the icons' animations as well as a general graphical overhaul.[17] The reactions were first shown off by reverse engineering expert Jane Manchun Wong on Twitter,[18] with mixed reactions both as replies and on Facebook itself.
In September 2019 it was revealed that Facebook is conducting a trial in Australia to hide the like count on posts. [19]In 2020 during the COVID-19 outbreak, a "Care" reaction was added to Facebook.[20]
During a public Q&A session in December 2014, CEO Mark Zuckerberg answered questions regarding the public's wish to have a "dislike" button on Facebook. Zuckerberg said: "There's something that's just so simple about the 'like' button' ... but giving people more ways of expressing more emotions would be powerful. We need to figure out the right way to do it so it ends up being a force for good, not a force for bad and demeaning the posts that people are putting out there." While suggesting the comment field for users who feel the like button is not appropriate, he said that Facebook had "no plans" to introduce a dislike button.[21]
In a new Q&A in September 2015, Zuckerberg said that Facebook was working on an "empathy button", such as for showing support to victims of tragedies. He further commented that "People aren't looking for an ability to downvote other people's posts. What they really want is to be able to express empathy. Not every moment is a good moment, right? And if you are sharing something that is sad, whether it's something in current events like the refugee crisis that touches you or if a family member passed away, then it might not feel comfortable to Like that post."[22] In February 2016, Facebook announced its "Reactions", offering different ways for users to interact with posts through the like button, including "Love", "Haha", "Wow", "Sad", and "Angry",[11][13] with the later addition of "Care" in March 2020 due to the COVID-19 pandemic.[23]
The Like button is one of Facebook's social plug-ins, which are features for websites outside Facebook as part of its Open Graph.[24][25] Speaking at the company's F8 developer conference on April 21, 2010, the day of the launch, CEO Mark Zuckerberg said "We are building a Web where the default is social".[25][26] The like button is implemented similarly to an advertising network, in that as more sites participate, Facebook is given a vast amount of information about who visits which websites and in what time period. When loading a website that has the like button enabled, the user's web browser connects to Facebook's servers, which record which website was visited, and by what user.[27]
A week after the release of the social plugins, Facebook announced that 50,000 websites had installed the features, including the like button.[28] Five months later, the number had increased to 2 million websites.[29]
In December 2010 and in the United States, Microsoft's Bing search engine partnered with Facebook to identify which links in search results have been "liked" by the searcher's Facebook friends.[30][31]
The number of "likes" on Facebook can serve as a measurement of interest and/or popularity in a particular brand, product or personality, though there have also been reports of the "overblown importance" of likes.[32] Due to social media's influence in shaping reputations,[33] there exist companies specializing in selling "likes" from fake accounts.[34] This has caused issues for companies advertising on Facebook, due to receiving an abundance of likes without credibility that distort actual user metrics.[34] Facebook's Terms of Service agreement states that users are only allowed to have one personal page,[35] and it has an ongoing "war" against fake accounts.[36][37] A May 2015 estimate put the number of fake accounts at 170 million,[38] and a Symantec study in September 2011 found that 15% of 3.5 million video posts were made through fake likes.[39]
