The European Union is a political and economic union consisting of 28 member states, which are subject to the obligations and the privileges of the membership. Countries which form part of the European Union are therefore characterized by their ongoing efforts to create a common European area with an internal market which promotes scientific and technological development.
What is more, the European Union and the United States are tied not only by the world’s largest bilateral trade agreement, but also by common investments, which form part of the most integrated economic relationship in the world. Advancements within the EU are therefore seen as important building blocks of this relationship. One of the most recent developments concerns the European Union’s copyright reforms, which have been an ongoing phenomenon for the past couple of years.
Apart from Article 11 of the proposed EU copyright reform (granting direct copyright over online use of press publications), which derives from the ancillary copyright for press publishers introduced in Germany in 2013, Article 13 has also raised a few eyebrows, as it proposes to permanently commit internet platforms to so-called upload filters. While supporters of the clause in question see this as an essential technological development ensuring correct copyright measures in movies, music, or texts, its opponents fear that it will weaken the network culture and threaten the right to freedom of expression with unforeseeable consequences.
We must therefore ask ourselves what the upload filters are all about, how they work, where they have already been implemented, and most importantly, why do they cause such heated debates?
It now looks like the upload filters ostensibly required by Article 13 will come after all.
On Wednesday, March 13th representatives of the EU Parliament, Commission and EU member states have agreed on a final text on the reform of EU copyright law. In the near future, only the European Parliament will have to vote on it. However, it is assumed that there will be no surprising change: Since all three institutions have already reached agreement on the text, it would be very unusual for Parliament to reject it. However, this does not stop opponents of the reform from continuing to argue against upload filters: In addition to online
Provisions to check content for copyright infringement will only apply to large sites, and smaller ones would be spared. Online encyclopedias such as Wikipedia are also to be exempted from the obligation to check content. The European Commission have also presented another directive in which upload filters play a key role: As part of the fight against terrorism, internet platforms are to be forced to examine all content for terrorist propaganda. What was not included in the regulation, however, was an exception for small website operators or open source offerings. This means that the upload filter policy would be a blanket policy, covering all nations. In the context of upload filters, Article 13 is of particular interest, even though it is not exactly mentioned. The European Parliament does not tell operators of online platforms how to ensure copyright protection. But critics and observers assume that there is no other option: According to the draft, platforms should check their content for copyright infringements already, before publishing anything. Due to the enormous volume of data, this is practically impossible without automated upload filters.
Upload filters are automated computer programs that scan data either when it is uploaded online or before it is published on a platform, and subsequently verify it according to certain criteria. There are three possible scenarios upon detecting content which does not conform to previously defined criteria – it is either blocked, the user is prevented from uploading, or the content is simply modified to match all norms. Upload filters can either be installed on individual sites and apps, implemented by web hosts, or by the user's internet provider. They can be used for the following purposes:
It is the last point that has recently triggered heated debates about upload filters among members of the European Parliament in the context of copyright law.
Upload filters require two essential components, one of them being a database of impermissible data stored in the form of hash values. In the case of the current EU-driven incentive, such a database would contain copyright-protected material.
Hash values, which are primarily used to store passwords, are strings of letters and numbers generated by mathematical functions from source materials. The same source material always produces the same hash value. However, it is not possible to deduce the source material from hash values.
An algorithm compares the hash values of copyrighted material with those of the uploaded data. An overlap between the two prevents the file from being uploaded. Nevertheless, upload filters do not become activated solely in cases of completely identical or very similar files. With the aid of various machine learning methods, you can spot individual components in images, videos, song parts, or texts. It is even possible to model underlying files to a certain extent. Let’s take cat images as an example. From a database of cat images, algorithms are able to learn how a cat looks and subsequently recognize new cat images that have not yet been saved in a database.
A nationwide commitment to upload filters would be a far-reaching step. However, in order to validate the large amounts of data uploaded onto various platforms on a daily basis, large internet companies have already been using this technology for a long time.
YouTube’s upload filter – Content ID – checks all newly uploaded videos for copyright infringements. Upon detection of content which violates respective regulations, copyright owners can act in three different ways:
In particular, the unauthorized distribution of movies, shows, songs, and music videos is to be prevented by this method. According to YouTube, the algorithm in question spares the work of 180,000 human inspectors.
The world’s largest social network – Facebook – predominantly uses upload filters to spot posts, images, and videos which are violent, inappropriate for young viewers, and offensive even before their publication. In order to combat terrorist or extremist content, Facebook, Twitter, Microsoft, and YouTube resort to a common database compliant with the operations of Europol – the European Police Authority.
As individual files are uploaded onto Microsoft’s cloud, the file hosting service in question performs automatic data analysis called PhotoDNA, which is predominantly used to combat child pornography. In this way, in 2015 for example, the German Federal Criminal Police was able to detect a pedophile with the aid of evidence provided by Microsoft.
Upon requests by various publishers, this social network for scientific publications was forced to introduce upload filters to identify unauthorized secondary publications and plagiarisms. The algorithm simply decided whether publications should only be made available to certain research groups or should be deleted it their entirety instead.
Although upload filters and their fight against child pornography, extremism, and copyright infringement initially sounds like a support-worthy cause, they also cause some considerable risks, which are incessantly pointed out by opponents of this new EU copyright law.
Practical applications show that algorithms have long been susceptible to errors. For instance, they are relatively easy to trick when carrying copyrighted material across blocking filters. Nonetheless, what seems to be even more worrying is that computer programs often censor permissible content. In this way, algorithms do not spot parodies, remixes, or tributes, which are generally covered by copyright law. Critics therefore not only speak of restrictions to artistic freedom, but also of an end to “meme culture.” This internet phenomenon is often based on recontextualizing copyright-protected images, videos, and songs, and even sometimes contributes towards the redistribution of content which has been changed in its entirety.
It is also possible to fraudulently claim copyrighted material and register it in a database. The spread of content unprotected by copyrights would therefore be impossible before determining the true owner.
Upload filters simultaneously provide a means for pre-censoring and controlling government-owned information. When misused, upload filters could favor the restriction of the right to freedom of expression and of the press. For instance, if databases were not filled with copyrighted material, but rather with unpopular statements and other forms of criticism directed at the State, then they could no longer be freely voiced on the internet. The implementation of such forms of technology gives a taste of what the nationwide content-filtering policy in China feels like.
The redesign of copyright laws in the European Union has considerably heightened the public’s awareness of upload filters. Copyrights holders such as publishers, film distributors, and the music industry demand improved protection of their copyrighted works on digital distribution channels and urge the prevention of unauthorized data disclosure (already taking place on platforms such as YouTube).
On the other side of the fence, however, there are various associations, internet activists, civil rights campaigners, Wikipedia operators, and critically-minded politicians spread across various parties. Although they are in favor of the aims of the proposed act and support the protection of intellectual property, they point out that upload filters are not the right way to go at all. They believe that the filters in question go far beyond their main objective, are not yet fully developed, and would pose a threat to freedom of expression.

Just because a photograph or artwork is available to view on the internet, doesn’t mean that you can use it for your own purposes. The creator’s consent and payment for royalties are often required. The rules don’t solely apply to sharing images that don’t belong to you; even if you use your own, you have to stick to certain guidelines.
YouTube has revolutionized the internet: since it was founded, it has been inundated with video content and more than a billion users have been recorded. No other alternative has come close to this impressive amount. But what are the other alternatives to YouTube and what do they have to offer? Here are the four best YouTube alternatives at a glance.
Legal disputes don’t necessarily have to be settled in court. In many cases, copyright law-related issues can be resolved outside of court using a cease-and-desist letter.
