This refers to any natural or legal person located or established in the Union who has received and accepted a written mandate from an AI system or general-purpose AI model provider to perform and carry out the obligations and procedures on their behalf.
Importer
An importer refers to a natural or legal person located or established in the EU who places an AI system on the market bearing the name and trademark of a natural or legal person established in a third country.
Distributor
This refers to a natural or legal person within the supply chain, other than the provider or the importer, that makes an AI system available within the EU market.
Operator
This refers to a provider, product manufacturer, deployer, authorized representative, importer, or distributor.
Notifying Authority
This refers to the national authority responsible for setting up and carrying out the necessary procedures for assessing, designating, notifying, and monitoring conformity assessment bodies.
This refers to the process of demonstrating whether an AI system can meet the requirements set out in Chapter III, Section 2 of the AI Act relating to a high-risk AI system.
Conformity Assessment Body
This refers to the body responsible for conducting third-party conformity assessment activities, including testing, certification, and inspection.
Notified Body
This refers to a conformity assessment body that has been notified in accordance with the provisions of the AI Act and other relevant Union harmonization legislation.
CE Marking
This refers to a provider's marking to an AI system that indicates its compliance with the requirements set out in Chapter III, Section 2 of the AI Act and other relevant Union harmonization legislation.
Post-Market Monitoring System
This refers to all the activities providers of an AI system have to do to collect and review experience gained from the use of AI systems to identify and address any immediate issues via corrective and preventive measures.
Market Surveillance Authority
This refers to any national authority responsible for carrying out activities related to the provisions of Regulation (EU) 2019/1020.
Biometric Data
This refers to personal data resulting from specific technical processing relating to the physical, physiological, or behavioral characteristics of a natural person, such as facial images or dactyloscopic data.
Biometric Identification
This refers to the automated recognition of physical, physiological, behavioral, or psychological human features to establish the identity of a natural person by comparing the biometric data of that individual to the biometric data of individuals stored in a database.
Biometric Verification
This means the automated, one-to-one verification, including authentication, of the identity of natural persons by comparing their biometric data to previously provided biometric data.
Special Categories of Personal Data
This refers to categories of personal data defined per Article 9(1) of Regulation (EU) 2016/679, Article 10 of Directive (EU) 2016/680, and Article 10(1) of Regulation (EU) 2018/1725.
Emotion Recognition System
This refers to an AI system that can identify or infer the emotions and intentions of natural persons based on their biometric data.
Biometric Categorization System
This refers to an AI system that can assign natural persons to specific categories based on their biometric data unless it is strictly necessary for objective technical reasons.
Remote Biometric Identification System
This refers to an AI system that can identify natural persons without their active involvement, typically at a distance through the comparison of their biometric data with that available in a reference database.
Real-time Remote Biometric Identification System
This refers to a remote biometric identification system that can collect, compare, and identify biometric data without any significant delay for instant identification.
Post Remote Biometric Identification System
This refers to any Biometric Identification System that is not real-time in nature.
Law Enforcement Authority
Law Enforcement Authority refers to any public authority or authorized body/entity competent in preventing, investigating, detecting, or prosecuting criminal offenses or executing criminal penalties, including safeguards against threats to public security. Additionally, it may also refer to entities empowered by a member state law to exercise public authority and powers for the aforementioned purposes.
Law Enforcement
This refers to the activities carried out by a law enforcement authority or on their behalf by third parties to prevent, investigate, detect, or prosecute criminal offenses or execute criminal penalties.
AI Office
This refers to the Commission's functions related to the implementation, monitoring, and supervision of AI systems and general-purpose AI models, and AI governance developed under the European Artificial Intelligence Office.
National Competent Authority
This refers to a notifying authority or a market surveillance authority; as regards AI systems put into service or used by Union institutions, agencies, offices, and bodies. References to national competent authorities or market surveillance authorities in this Regulation shall be construed as references to the European Data Protection Supervisor.
Personal Data
Personal data are any information that is related to an identified or identifiable natural person.
Non-Personal Data
This refers to any other data than personal data as defined under GDPR.
This refers to consent provided by the subject, which is a freely given, specific, unambiguous, and voluntary expression of his or her willingness to participate in a particular testing in real-world conditions after having been informed of all aspects of the testing that are relevant to the subject's decision to participate.
Deep Fake
This refers to AI-generated or manipulated image, audio, or video content that resembles existing persons, objects, places, entities, or events and would falsely appear to a person to be authentic or truthful.
General-Purpose AI Model
General-purpose AI model is an AI model, including when trained with a large amount of data using self-supervision at scale, that displays significant generality and is capable to competently perform a wide range of distinct tasks regardless of the way the model is released on the market and that can be integrated into a variety of downstream systems or applications.
Systemic Risk
This refers to risk specific to the high-impact capabilities of general-purpose AI models, which may pose a risk to the Union market owing to their reach or due to actual or reasonably foreseeable negative effects on public health, safety, public security, fundamental rights, or society as a whole that can be propagated at scale across the value chain.
