The 4NSEEK forensic analysis tool is no longer supported.

Financing, work program and call

Project 4NSEEK “Forensic Against Sexual Exploitation of Children” is co-financed by the European Union (UE) through the financing program Internal Security Fund - Police, ISFP-2017-AG-CYBER call.


The timeframe of the Project is from January 2019 to June 2021.

Motivation and justification

The objective of this call is to finance projects in the area of the fight against Cybercrime and Child Sexual Abuse. In this regard, the projects must address the fight against sexual exploitation of children (with special attention to the identification of victims and child sexual tourism), including:

  • Developing capacity and expertise of law enforcement and judicial authorities. This includes, for instance, the development of investigative and forensics tools to address the challenges posed by the use of encryption by criminals and its impact on criminal investigations and supporting law enforcement authorities' engagement in the area of Internet governance;
  • Fostering cross-border cooperation among law enforcement and judicial authorities. This includes, for instance, the setting up of mechanisms facilitating swift access to seized evidence or intelligence (or both) across borders;
  • Fostering cross-border cooperation between law enforcement/judicial authorities and private entities. This includes, for instance, the establishment of mechanisms supporting public-private cooperation.

INCIBE, as a national reference entity for the development of cybersecurity and under the Collaboration Framework Agreement between the State Secretariat of Digital Advance and the Secretary of State for Security of the Ministry of the Interior, collaborates closely and proactively with the Spanish LEAs in criminal investigations. Part of this collaboration focuses on the fight against child sexual abuse, initiated under the European ASASEC project.


The main benefits of this call are:

  • Promote international police cooperation in this specific type of crime, providing a common tool and organizing activities for coordination, share good practices and receive advanced training.
  • The awareness and prevention of this cybercrime. This dissemination will be carried out in Spanish, English and Portuguese through the most suitable channels focused on minors, adolescents, families and educators.
  • Improve the capabilities of the forensic tool 4NSEEK, (initiated under the European project ASASEC and currently used by Spanish LEA in registers) to collect digital evidence related to child sexual abuse.
  • The free provision of the forensic tool 4NSEEK, to all the LEA participants in the project, as well as to other interested police.


The main objectives of the project are:

  • The promotion of international police cooperation with the use of common forensic tools and procedures, as well as advanced training in this matter that will materialize in the event Cybersecurity Summer Bootcamp 2019 and 2020 editions.
  • The improvement of the 4NSEEK forensic analysis tool specialized in child abuse including innovative improvements based on the needs of the police officers involved, reinforced by the scientific research of the participating Universities.
  • The preparation and dissemination of guides and other materials to detect and prevent the sexual abuse of minors through a group of experts in this type of crime, composed of psychologists, social workers, educators, legislators, police and prosecutors.


The main target group and beneficiaries of this project are:

  • The whole society (parents, educators, children, social services ...) will benefit from all the actions of the project to fight against the sexual exploitation of children, and directly, from the actions of awareness and prevention of this cybercrime.
  • LEAs will be able to reinforce cooperation and cross-border coordination, using the latest techniques and technologies. They will have a tool in a mature state that will help them increase the efficiency of their research and will have the opportunity to receive advanced training and share useful experiences to improve the fight against this type of crime.

Relevance and innovation

The 4NSEEK project has a strong innovative character. The technological solution developed will make use of the most advanced techniques and tools in forensic analysis, using, for example, artificial vision algorithms and automatic learning in its multimedia analysers to facilitate the Security Forces or bodies the resolution of cases related to child sexual abuse.

  • Forensic procedure. INCIBE has developed a procedure that brings together in a single document the technical and legal vision of the practice of forensic analysis in the Spanish legislative framework. This procedure has been supervised by FCSE so that it could be of the greatest use to its agents in the execution of forensic analysis.
  • #StopChildAbuse campaign to raise awareness about the sexual abuse and exploitation of minors on the Internet. More information and all resources here.

  • On February 10, 2021, at 4:00 p.m. CET, coinciding with Safer Internet Day 2021, a seminar about 4NSEEK forensic tool took place. The objective was to present the main functionalities of the product and several users from international Law Enforcement Agencies explained their experience with this solution in cases related to child sexual abuse. This seminar was in online format with a duration of approximately 3 hours and was attended by 75 people from 22 different countries.

Conclusions and questions



The 4NSEEK Project has a consortium formed by:

Spanish National Cybersecurity Institute (INCIBE)



It is an organisation dependent on the Ministry of Economic Affairs and Digital Transformation, the Secretary of State for Digitalisation and Artificial Intelligence and consolidated as a reference entity for the development of cybersecurity and digital trust for the citizens, academic and research network, professionals, companies and especially for strategic sectors.

With an activity based on research, the provision of services and coordination with the agents with competences in the field, INCIBE contributes to build cybersecurity at a national and international level.

Its contribution to this project is based on the coordination of all partners and participates in all lines of the same: police training programs, the development of the forensic analysis tool and the development of awareness guides.



Universidad de León

The University of León is a Public University established on 1979. It has two campus: one in the city of León and another one in Ponferrada, both in the province of León. It has 9 Faculties and 3 Schools of Engineering, where 40 Bachelor Degrees and Double Degrees, 36 Official Master Degrees,16 Doctorate Programs and 21 Own Titles are taught. Nowadays, it has approximately 13000 students. Since it was established, the University of León has been committed to internationalization, attracting, over the last few years, students from more than 40 countries thanks to the different mobility programs in which it participates. In addition, the University of León has agreements for student mobility with more than 300 universities around the world.

In the 4NSEEK Project, the research group GVIS (Group for Vision and Intelligent Systems), formerly known as VARP (Artificial Vision and Pattern Recognition) will work on behalf of the University of León. This group has been carrying out research in the fields of Artificial Vision and Machine Learning since 2003.

In particular, its contribution to 4NSEEK will consist of applying and developing methods based on Computer Vision, Machine Learning and Deep Learning for detecting Child Sexual Abuse (CSA) content in images and videos. In particular, models for detecting CSA based on the contents, file names, or other metadata of the multimedia files of the images and videos will be evaluated, or even a combination of the above.

ASGARD aims to contribute to LEA Technological Autonomy, by building a sustainable, long-lasting community for law enforcement agencies (LEAs) and the R&D industry. This community will develop, maintain and evolve a best-of-class tool set for the extraction, fusion, exchange and analysis of Big Data, including cyber-offense data for forensic investigation. ASGARD will help LEAs to significantly increase their analytical capabilities. Forensics being a focus of ASGARD, both intelligence and foresight dimensions are addressed by the project.

INCIBE as leader of the 4NSEEK project, is part of the ASGARD Advisory Board. The coordination of both projects is defining a series of initiatives whose purpose is the identification of synergies for a common goal: technical support to international LEAs in the fight against cybercrime.
