  • Privacy Enhancing Technologies in the EU Digital Omnibus Proposal: Clarifying the Role of PETs in the Definition of Personal Data under the GDPR Reviewed International journal

    Kenji Suzuki

    In: Morinaga, S., Nakano, Y., Tono, K. (eds) New Frontiers in Artificial Intelligence. JSAI-isAI 2026.Lecture Notes in Computer Science   16608   87 - 100   2026.6

    The EU Digital Omnibus Proposal was published by the European Commission on November 19, 2025. It aims to simplify the overall EU digital legislative framework. As part of this effort, it proposes amendments to clarify the interpretation of “personal data” under the General Data Protection Regulation (GDPR). In particular, the proposal introduces a subject-specific and context-dependent assessment of identifiability, under which information does not constitute personal data for an entity that lacks reasonably available means of re-identification. However, the current GDPR framework lacks clarity regarding how identifiability should be assessed across different entities.

    This paper focuses on the judgment of Court of Justice of the European Union (CJEU) in SRB (Case C-413/23 P European Data Protection Supervisor v Single Resolution Board [2025]) as the institutional background of this amendment. While the judgment recognizes that identifiability may depend on the means reasonably available to each entity, it also maintains a controller-based standard for the transparency obligation, thereby separating the assessment of identifiability from the establishment of that obligation.

    Against this background, this paper addresses the following research question: how the EU Digital Omnibus Proposal transforms the legal role of privacy enhancing technologies (PETs) from supplementary safeguards into institutional elements that define the scope of personal data under the GDPR. It argues that the proposal repositions PETs as structural components that shape the range of reasonably available re-identification means and thereby influence the scope of application and the activation of obligations under the GDPR.

    This institutional design suggests a new approach to balancing data protection and data utilization, in which the boundary between personal and non-personal data is constructed through technology-dependent identifiability assessments.

    This paper clarifies the usefulness and limitations of machine unlearning about data protection legislation. The machine unlearning efficiently removes specific data from AI pretrained models and plays a vital role in responding to data protection legislation. EU General Data Protection Regulation (GDPR) stip- ulates the right to be forgotten, but the legal system differs in other regions. Therefore, the data protection legislation of each jurisdiction (EU, United States, India, and Japan) is analyzed, and the legal applicability of machine unlearning are evaluated. As a result, more effective use of machine unlearning is expected in the development of the guidelines and legislation in the future.

    This article provides an explanation of the “Act on the Promotion of Research, Development, and Utilization of Artificial Intelligence Technologies” (the “AI Act”), which came into effect in Japan on June 4, 2025. While the Act places emphasis on promoting AI research, development, and utilization, it also establishes an institutional foundation for risk management. Its distinguishing feature lies in adopting a uniquely Japanese approach.

    The EU AI Act's Prohibited AI Practices, which came into effect in February 2025, prohibits the use of AI systems for the purpose of inferring the emotions of natural persons in the workplace and in educational institutions. The specific details of the regulation are clarified in the Guidelines for Prohibited AI Practices. On the other hand, in Japan, there are no clear guidelines or regulations on emotion inference technology, and there have been some examples of demonstration experiments and introduction of such technology into products and services. In this paper, I examine how the protection of personal information should be handled in emotion inference technology. This paper clarifies that the regulations in the EU suggest the necessity of careful institutional design in Japan as well, taking into account the purpose of use, technical limitations, and the relationship with inner freedom.

  • Considerations from the DABUS Invention Case Decisions in Japan and Germany Legal Issues of AI Fully Autonomous Invention

    Authorship:Lead author   Language:Japanese  

    The Japanese court decision on May 16, 2024 (the “DABUS Invention Case”), in which the applicability of AI as an “inventor” was disputed, provided an important opportunity to question how Japanese patent law should respond to the development of AI. The day is not far off when “AI fully autonomous inventions” will be realized, which will not require any human creative involvement. The “inventor” as defined in patent law is interpreted to be limited to a “natural person,” but with the future evolution of AI, how to treat “AI fully autonomous inventions” will be a major issue. The legal issues concerning “AI fully autonomous inventions” are discussed by comparing the decision of the German Federal Court of Justice in the “DABUS Invention Case” on June 11, 2024 with court decisions in Japan. Under the current Japanese patent law, “AI fully autonomous inventions” may cause the problem of absence of “inventor” or presumption. Therefore, we believe that there is a limit to the solution of this problem by the theory of interpretation, and that it is necessary to consider the problem by the legislation.

    The use of large-scale, web-scraped datasets to train face recognition models has raised significant privacy and bias concerns. Synthetic methods mitigate these concerns and provide scalable and controllable face generation to enable fair and accurate face recognition. However, existing synthetic datasets display limited intraclass and interclass diversity and do not match the face recognition performance obtained using real datasets. Here, we propose VariFace, a two-stage diffusion-based pipeline to create fair and diverse synthetic face datasets to train face recognition models. Specifically, we introduce three methods: Face Recognition Consistency to refine demographic labels, Face Vendi Score Guidance to improve interclass diversity, and Divergence Score Conditioning to balance the identity preservation-intraclass diversity trade-off. When constrained to the same dataset size, VariFace considerably outperforms previous synthetic datasets (0.9200 → 0.9405) and achieves comparable performance to face recognition models trained with real data (Real Gap = -0.0065). In an unconstrained setting, VariFace not only consistently achieves better performance compared to previous synthetic methods across dataset sizes but also, for the first time, outperforms the real dataset (CASIA-WebFace) across six evaluation datasets. This sets a new state-of-the-art performance with an average face verification accuracy of 0.9567 (Real Gap = +0.0097) across LFW, CFP-FP, CPLFW, AgeDB, and CALFW datasets and 0.9366 (Real Gap = +0.0380) on the RFW dataset.

    This paper discusses the importance of “legitimate interests” as a legal basis for data processing under the EU General Data Protection Regulation (GDPR) and the legal issues involved. Data processing based on legitimate interests is used in many situations, but its application is difficult to interpret legally because it is a general provision. However, legitimate interests require an understanding of the position of legitimate interests, including the impact of recent technological evolution, legislation in the EU, and changes in social acceptance. The purpose of this paper is to summarize the complex legal issues related to legitimate interests from the perspective of the use of AI learning data, based on recent EU legislative trends, court cases, academic theories, and the views of the data protection authorities in Italy, the Netherlands, and France. Although the three-step criteria of legitimacy, necessity, and proportionality have been used in recent cases, the specific legal interpretations are still unclear.

    Training data and learned models may contain personal information that should be erased based on legal requirements. However, erasing such data from the learned model and rebuilding the model is economically expensive. For this reason, machine unlearning has been attracting attention as a technique for forgetting specific personal information from learned models. This paper focuses on the significance and technical limitations of machine unlearning and clarifies its legal status. The EU's GDPR and the U.S. state of California's CCPA are open to flexible interpretations of the technical limitations.

    Large-scale language models are a high-performance technology that can bring about change, but their behavior is very complex. Also, there are potential challenges such as misinformation, bias, and subliminal manipulation. Explainable AI is a technology that makes black box models understandable to humans. In December 2023, the European AI Act incorporates regulations on infrastructure models, generative AI, and general-purpose AI. We will discuss what kind of legal role explainable AI has for large-scale language models.

    Advances in generative AI, such as large language models and image generation AI, are bringing about revolutionary technological changes. On the other hand, there are concerns about ethical, legal, and social issues posed by generative AI, and it is necessary to consider the nature of co-creation between generative AI and humans in the information society.
    This paper considers the issues based on the EU AI Act, a comprehensive regulatory act on AI. With the rapid development of generative AI, the European Parliament adopted the EU AI Act in June 2023, adding provisions on foundation models and generative AI to the amendment. In relation to the new development of generative AI and its relationship with society, this paper outlines the legal system including technical aspects regarding the obligations of providers of foundation models and generative AI. The paper examines how to make the best use of generative AI and create fair society in our country.

    Our goal is to develop fine-grained real-image editing methods suitable for real-world applications. In this paper, we first summarize four requirements for these methods and propose a novel diffusion-based image editing framework with pixel-wise guidance that satisfies these requirements. Specifically, we train pixel-classifiers with a few annotated data and then infer the segmentation map of a target image. Users then manipulate the map to instruct how the image will be edited. We utilize a pre-trained diffusion model to generate edited images aligned with the user's intention with pixel-wise guidance. The effective combination of proposed guidance and other techniques enables highly controllable editing with preserving the outside of the edited area, which results in meeting our requirements. The experimental results demonstrate that our proposal outperforms the GAN-based method for editing quality and speed.

  • Explainable Data Bias Mitigation

    I propose an explainable fairness method that can not only mitigate data bias but also make humans understand the reason. Machine learning algorithms have high-risk use cases, such as hiring and loan decision, that demand fairness, accountability, and transparency. Differences in AI predictions due to sensitive attributes, such as gender, race, and age, have become fairness issue. Although various methods of bias mitigation in AI have been proposed, there is a problem that conventional methods do not allow humans to intuitively understand on how basis data bias mitigation is performed. Therefore, I propose a method of bias mitigation by using explainable AI. My proposed method allows humans to understand how bias mitigation is achieved. Experimental results of applying this method to credit scoring by German Credit dataset shows that the statistical parity difference improved from -0.108 to -0.004 on gender.

    Language:English  

    Generative models, particularly GANs, have been utilized for image editing. Although GAN-based methods perform well on generating reasonable contents aligned with the user's intentions, they struggle to strictly preserve the contents outside the editing region. To address this issue, we use diffusion models instead of GANs and propose a novel image-editing method, based on pixel-wise guidance. Specifically, we first train pixel-classifiers with few annotated data and then estimate the semantic segmentation map of a target image. Users then manipulate the map to instruct how the image is to be edited. The diffusion model generates an edited image via guidance by pixel-wise classifiers, such that the resultant image aligns with the manipulated map. As the guidance is conducted pixel-wise, the proposed method can create reasonable contents in the editing region while preserving the contents outside this region. The experimental results validate the advantages of the proposed method both quantitatively and qualitatively.

    Identifying the influence of training data for data cleansing can improve the accuracy of deep learning. An approach with stochastic gradient descent (SGD) called SGD-influence to calculate the influence scores was proposed, but, the calculation costs are expensive. It is necessary to temporally store the parameters of the model during training phase for inference phase to calculate influence sores. In close connection with the previous method, we propose a method to reduce cache files to store the parameters in training phase for calculating inference score. We only adopt the final parameters in last epoch for influence functions calculation. In our experiments on classification, the cache size of training using MNIST dataset with our approach is 1.236 MB. On the other hand, the previous method used cache size of 1.932 GB in last epoch. It means that cache size has been reduced to 1/1,563. We also observed the accuracy improvement by data cleansing with removal of negatively influential data using our approach as well as the previous method. Moreover, our simple and general proposed method to calculate influence scores is available on our auto ML tool without programing, Neural Network Console. The source code is also available.

    While there exist a plethora of deep learning tools and frameworks, the fast-growing complexity of the field brings new demands and challenges, such as more flexible network design, speedy computation on distributed setting, and compatibility between different tools. In this paper, we introduce Neural Network Libraries (this https URL), a deep learning framework designed from engineer's perspective, with emphasis on usability and compatibility as its core design principles. We elaborate on each of our design principles and its merits, and validate our attempts via experiments.

    Identifying the influence of training data for data cleansing can improve the accuracy of deep learning. An approach with stochastic gradient descent (SGD) called SGD-influence to calculate the influence scores was proposed, but, the calculation costs are expensive. It is necessary to temporally store the parameters of the model during training phase for inference phase to calculate influence sores. In close connection with the previous method, we propose a method to reduce cache files to store the parameters in training phase for calculating inference score. We only adopt the final parameters in last epoch for influence functions calculation. In our experiments on classification, the cache size of training using MNIST dataset with our approach is 1.236 MB. On the other hand, the previous method used cache size of 1.932 GB in last epoch. It means that cache size has been reduced to 1/1,563. We also observed the accuracy improvement by data cleansing with removal of negatively influential data using our approach as well as the previous method. Moreover, our simple and general proposed method to calculate influence scores is available on our auto ML tool without programing, Neural Network Console. The source code is also available.

    We report structural and optical properties of GaSb/GaAs self-assembled quantum dots (QDs) grown by molecular beam epitaxy. The QDs, with nanometer-scale dimensions, were characterized by atomic force microscopy. Furthermore, in photoluminescence (PL) measurements the feature from the QDs was observed at ∼1.1 eV, clearly separated from that of the wetting layer at ∼1.3 eV. With increasing excitation power, the peak from the QDs displayed a large shift towards higher energy. In addition, the temperature dependence of PL yielded a large thermal activation energy, 130 meV, confirming the strong localization of excitons in the QDs.

     More details

    Event date: 2025.5

    Language:English   Presentation type:Oral presentation (invited, special)  

    This talk explores the potential and limitations of machine unlearning in the context of data protection laws. Machine unlearning refers to a set of techniques that enable the efficient removal of specific data from trained AI models. As concerns over data privacy grow, such techniques are increasingly important for compliance with legal frameworks. While the EU General Data Protection Regulation (GDPR) explicitly guarantees the "right to be forgotten," data protection regimes in other jurisdictions, including the United States, India, and Japan, differ significantly. This presentation analyzes the legal compatibility of machine unlearning across these regions and assesses its practical applicability. The findings suggest that, as machine unlearning technologies continue to evolve, the development of legal guidelines and legislative support will be crucial to realizing their full potential in safeguarding individual privacy.

    In the development of human resources through joint education between universities and companies, a complementary relationship is essential. Until now, educational programs have been designed with a focus on the complementary relationship between the theoretical and practical aspects of data science and AI. However, moving forward, it will be necessary to also emphasize the cultivation of a global perspective, economic value, and ethical values. In the EU, regulatory measures, including responses to ethical, legal, and social issues arising from generative AI, have been introduced under the "EU AI Act." Against this backdrop, I will explore the ideal form of joint education through industry-academia collaboration from the perspective of practitioner educators who are AI developers, legal scholars, and educators.

  • Case Study: Case of a request for confirmation of non-existence of claims regarding the use of copyrighted material in a music school (Supreme Court decision, October 24, 2022, Minshu Vol. 76, No. 6, p. 1348)

    Language:Japanese   Presentation type:Oral presentation (general)  

    This article focuses on a case in which copyright management of musical compositions in a music school was contested. X and others who run a music school sued Y, a copyright management company, for a declaration that Y had no right to claim damages based on torts for copyright (performance rights) infringement against X and others for musical compositions managed by teachers and students in lessons. The first instance ruling confirmed the performance rights of musical compositions for the students' performances, but the appeal court denied it. The Supreme Court upheld the appeal court ruling and held that the performance rights do not extend to musical compositions performed by students in music schools, and that copyright management must be limited to teachers' performances. The standard of judgment did not use the "karaoke doctrine" that had been used in previous cases, but instead presented a general theory based on the "overall balance doctrine." This ruling indicated that when determining who is using musical compositions based on the form of performance, various circumstances such as the purpose and manner of the performance, and the content and degree of involvement in the performance should be taken into consideration.

    AI training data and AI pretrained models may contain personal data that should be erased based on legal requirements. However, erasing pertinent data from AI pretrained models and rebuilding AI models involves economic costs. For this reason, machine unlearning has attracted attention as a technique to forget specific personal data from AI trained models. This presentation will focus on the significance and technical limitations of machine unlearning and clarify its legal status. The application of machine unlearning to privacy protection legislation in various countries and regions will also be discussed, and its usefulness and limitations will be noted.

    The EU AI Act, which was passed by the EU on May 21, 2024 and entered into force on August 1, 2024, is a comprehensive regulation on AI. The EU AI Act will gradually come into effect on February 2, 2025 for “prohibited AI” and on August 2, 2025 for “general-purpose AI models. While previously relying on voluntary regulations such as AI ethical guidelines, the “EU AI Act” has transformed them into legally binding regulations. Its scope of application covers a broad value chain, from the developers of AI models to their providers and operators.

    In addition to the regulation based on the “risk-based approach” presented in the draft three years ago, a new regulation on General Purpose AI Models (GPAI) has also been introduced. Furthermore, it is important to note that the regulations are not limited to the EU, but also include extraterritorial application provisions, which apply to businesses outside the EU for products and services provided within the EU.

    The EU AI Act is also attracting attention as a “Brussels effect,” in which EU regulations spill over into legal systems around the world. Deepening our understanding of it will have important implications for future research and development. In particular, for those involved in data science and AI R&D, this seminar will provide detailed and easy-to-understand explanations from my perspective as an AI R&D and information law researcher. We sincerely look forward to your participation.

    On March 12, 2026, I will deliver a lecture titled “AI Risks: Cybersecurity under the EU AI Act” at the Graduate University for Information Security's Special SSL Symposium for Corporate Legal Affairs. The EU has undergone a significant shift from AI ethics and voluntary guidelines to legally binding regulations with penalties, establishing an AI governance framework centered on the EU AI Act. This presentation will explain the cybersecurity requirements and accountability structures demanded of AI systems within this new regulatory framework. Specifically, high-risk AI systems require: risk management to assess potential dangers beforehand; preparation of technical documentation detailing the system's design and architecture; logging to track operational status; ensuring appropriate human oversight; and safe design incorporating accuracy, robustness, and cybersecurity. We will also overview the relationship between cyberattacks on AI (such as data contamination and adversarial inputs) and relevant EU legislation (GDPR, NIS2 Directive, Cyber Resilience Act). Compliance with the EU AI Act means not merely meeting regulations, but building corporate governance that enables the safe design and operation of AI, along with the ability to explain its safety. We hope this presentation offers practical insights for leveraging AI.

    The rapid evolution of artificial intelligence (AI), especially through technological innovations driven by generative AI, is having a profound impact on society. While it brings enhanced convenience and efficiency, it also raises a range of ethical, legal, and social challenges.

    This course will explain the mechanisms behind generative AI, which enables image generation and natural conversations. Through specific case studies, we will explore the societal impacts of generative AI. In particular, we will examine a wide range of pressing issues, including personal data breaches, the sophistication of criminal activity, the spread of misinformation, cyberattacks, impacts on education, copyright infringement, and rising unemployment.

    Furthermore, using autonomous driving technology—which can support the daily lives of older adults—as an example, we will analyze where responsibility lies from both ethical and legal perspectives. The course will also provide a clear explanation of the legal frameworks necessary for the appropriate use of AI technologies in society, along with insights into future developments.
