Let’s not take a step back in the fight against CSA

The Proposal for a Regulation laying down rules to prevent and combat child sexual abuse (CSA) will become one of the cornerstone pieces of legislation in the fight against the sexual abuse of children online. DOT Europe’s members have already undertaken serious steps in developing technology to effectively prevent and help to fight CSA, and are committed to continue these efforts.


CSAM in numbers:

  • In 2021, the National Center for Missing & Exploited Children (NCMEC) received over 85 million files of child sexual abuse material (CSAM) from around the web, and of that, 44.8 million contained video content. Of those, only 5.1 million video files were new content, leaving 39.7 million videos that are likely already known illegal content.
  • NCMEC reviews more than 25 million images annually. That’s more than 68,000 images per day.

Clearly, the problem of CSAM is enormous, global, goes across platforms and, the figures show, the majority of reports concerns known illegal content. Risk assessments, mitigation measures, and detection orders are measures proposed by the European Commission, to address the misuse of online services for the purposes of child sexual abuse (CSA). When it comes to the mitigation measures proposed, DOT Europe has 2 key recommendations that would render the proposal more effective.

1. Keep the flexible approach for providers to select the appropriate mitigation measures

2. Recognize the volume and quality of current voluntary measures in the fight against CSA

Flexible approach

All hosting service providers will be required to conduct a risk assessment to see how (un)likely their services are being used for the purpose of CSA. Once this is done, the proposal requires these providers to adopt mitigation measures to tackle those risks. Just like the Digital Services Act already does for VLOPs (very large online platforms). The proposal allows providers to select which technology and risk mitigation efforts are appropriate for their services (Recital 17). Keeping this flexibility is of tremendous importance to DOT Europe’s members when selecting appropriate and proportionate mitigation measures. There is no one-size-fits-all approach for providers with largely different content offering and services.

  • Moving this language to the actual body of the proposal would ensure this flexibility in adopting the appropriate measures is maintained.

Voluntary measures

The voluntary use of technologies to prevent online CSA and to detect CSAM is another important part in ensuring mitigation measures remain effective. DOT Europe’s members have long been leading innovation by developing and investing in detection and prevention technology. You can find a list of examples of such voluntary measures below. The current system based on voluntary detection and reporting by companies will no longer be possible once the interim solution currently in place expires. The current CSA proposal, unfortunately, does not recognise these voluntary efforts as mitigation measures, whereas they have proved crucial in tackling online CSA. This is really a step backwards as the large volume and quality of the work already undertaken voluntarily, could be in vein. And more importantly, it is likely to lead to further abuse material being spread online.

  • Voluntary efforts such as the ones mentioned below, should be recognized as a mitigation measure under Article 4 of the proposal

Did you know:

  • Discord scans all images uploaded to the platform using industry-standard DNA to detect matches with known CSAM?
  • Meta developed a safety alert that informs people who have shared viral, meme child exploitative content about the harm it can cause and warns that it is against their policies and there are legal consequences for sharing this material. This safety alert is shared in addition to removing the content, banking it and reporting it to NCMEC.
  • TikTok employs human and machine-based moderation tools like photo identification technologies, in alignment with industry standards, to identify and remove exploitative content. In addition, TikTok filters red-flag language and share information with NCMEC about situations that may indicate grooming behaviour, according to their policies and industry norms.
  • YouTube engineers developed CSAI Match: a world-leading technology used to scan and identify uploaded videos, and makes this available to other platforms and NGOs.
  • Google engineers developed Content Safety API, based on machine learning technology, and helps to identify content likely to contain abuse.
  • Microsoft developed PhotoDNA, a robust hash-matching technology to help find duplicates of known child sexual exploitation and abuse imagery. 
  • Snap Inc. gives parents, caregivers and other trusted adults insight into who their teens are communicating with on the app and allows them to report accounts of concern. It also uses proactive detection tools, such as PhotoDNA and Child Sexual Abuse Imagery (CSAI) Match technology to identify known illegal images and videos of CSAM.
  • The Tech Coalition , a global alliance with most of the leading tech companies, launched Project Protect, an ambitious five pillar plan to combat online child sexual exploitation and abuse. Whether it is funding independent research to inform industry priorities, developing new technology, or sharing hard-won knowledge and effective practice, each pillar of Project Protect is designed to generate objective outcomes that will accelerate industry progress in the fight against online child sexual exploitation and abuse.
