Ethical Use of AI in Software Systems

The ethical use of AI in software systems is an increasingly important consideration as AI technologies are integrated into many aspects of daily life. AI systems have the potential to transform industries, improve decision-making, and enhance user experiences. However, with these opportunities come ethical challenges, as AI systems can impact fairness, privacy, accountability, and transparency. Ethical AI seeks to ensure that these systems are developed and deployed responsibly, respecting human rights and minimising potential harms to individuals and society.

Ethical AI requires a balance between innovation and responsibility, where AI systems are not only designed to perform effectively but also align with societal values and legal standards. Key principles in ethical AI include fairness (avoiding bias and discrimination), transparency (making AI decisions understandable), accountability (ensuring human responsibility for AI outcomes), and privacy (safeguarding users’ personal data). Adhering to these principles is critical, as AI systems can sometimes reflect or amplify existing social biases, produce opaque outcomes, or inadvertently compromise privacy.

As regulatory bodies worldwide develop frameworks and laws to address these challenges, software engineers must stay informed and incorporate ethical considerations into their AI projects. International standards, such as the EU’s AI Act, along with guidelines from institutions like the UK Government and the Organisation for Economic Co-operation and Development (OECD), provide frameworks that guide ethical AI development. By following these guidelines, software engineers can develop AI systems that are trustworthy, safe, and aligned with ethical standards, ultimately benefiting users and fostering public trust in AI technology.

The current status of legal frameworks for the ethical use of AI, while advancing, remains fragmented and faces several challenges in addressing the complexities of rapidly evolving AI technologies. Regulations such as the EU’s AI Act, the UK’s pro-innovation AI guidelines, and Canada’s Artificial Intelligence and Data Act (AIDA) represent significant steps toward creating accountability, promoting transparency, and protecting human rights in AI. However, these frameworks vary widely in approach and scope, leading to inconsistencies that complicate compliance for global AI developers. For instance, the EU’s AI Act adopts a stringent, risk-based approach that categorises AI applications by their potential societal impact, whereas the UK’s approach is more flexible, allowing sector-specific regulators to craft tailored guidelines. This divergence reflects differing priorities — strict regulatory oversight versus innovation facilitation — which can create challenges for multinational companies trying to navigate these legal landscapes.

Moreover, current legal frameworks often struggle to keep pace with the speed of AI advancements, leading to regulatory gaps in emerging areas such as generative AI, autonomous systems, and adaptive learning models. AI regulations typically focus on transparency, privacy, and fairness, but the technical specifics of enforcing these principles—such as explainability in complex machine learning models—are still challenging to codify in law. This gap risks creating “grey areas” where AI systems may operate without clear accountability.

Another critical limitation is that many existing frameworks lack robust enforcement mechanisms, making it difficult to hold organisations accountable when ethical violations occur. For example, without a standardised global enforcement authority, companies can face different levels of scrutiny and consequences depending on where they operate. Additionally, while current frameworks emphasise principles such as fairness and accountability, operationalising these values in technical terms remains a challenge, as it is often unclear how to apply high-level ethical concepts in specific AI use cases.

The absence of unified, global standards and enforceable guidelines makes it difficult to ensure a consistent ethical foundation for AI across borders. While localised legal frameworks are valuable, their variability underscores the need for collaboration and harmonisation on an international scale. As a result, the current state of AI regulation provides a starting point for ethical governance but still requires further development to effectively guide AI’s role in society, protect individuals, and adapt to new technological realities.

EU regulation

The EU’s Artificial Intelligence Act (AI Act) is currently one of the most comprehensive legal frameworks for AI, particularly in its ambition to regulate AI across multiple dimensions, with a broad and well-defined approach to ethics, safety, and accountability.

Risk-Based Approach

The AI Act introduces a risk-based classification system for AI systems, categorising them into four levels:

  • Unacceptable
  • High
  • Limited
  • Minimal

This approach allows for targeted regulation, ensuring that the most potentially harmful applications — such as AI used in critical sectors like healthcare, law enforcement, and employment — are subject to the strictest oversight. This dynamic, tiered system is unique and is designed to focus resources and regulatory efforts where they are most needed.

Comprehensive Scope

Unlike previous AI regulations in other jurisdictions which may focus on specific industries or technologies, the EU’s AI Act has a wide-reaching scope. It covers all AI systems deployed in the EU, regardless of their origin, making it the first regulation to attempt to regulate AI holistically. The Act applies to public and private sector AI applications alike, offering a comprehensive framework for AI governance, which includes elements such as data governance, algorithmic transparency, and human oversight.

Focus on High-Risk AI Systems

The EU’s AI Act places a strong emphasis on high-risk AI systems, which must comply with specific requirements like rigorous risk assessments, data quality standards, documentation and transparency, and human oversight. This is particularly relevant in sensitive areas such as criminal justice, healthcare, and recruitment, where AI has the potential to directly affect individuals’ rights, safety, and well-being. These regulations ensure that AI systems in these areas undergo regular scrutiny and certification, offering a high degree of consumer protection.

Prohibition of Unacceptable Risks

The AI Act prohibits certain AI applications deemed to pose unacceptable risks, such as AI used for mass surveillance or social scoring. By taking a strong stance on these high-risk areas, the EU demonstrates its commitment to preventing AI systems that could infringe upon fundamental rights or enable systemic harm. This prohibition is one of the more stringent regulatory aspects in the global landscape.

Emphasis on Transparency and Accountability

The EU Act sets out clear and enforceable requirements for AI systems to provide transparent operations. These include making the decisions of high-risk AI systems explainable and accessible to users, and ensuring there is adequate human oversight. Furthermore, AI developers must maintain records that document how the system was designed, how it operates, and its impacts. This level of accountability and traceability is unprecedented in many other AI regulatory frameworks.

Global Applicability

The EU’s AI Act is not only groundbreaking in terms of its thorough regulation within Europe but also in its extraterritorial reach. It applies to all entities that deploy AI within the EU, regardless of where the company is based. This global applicability forces companies worldwide to comply with EU standards if they want to access the European market, positioning the AI Act as a potential global standard for AI regulation.

Human Rights and Ethical Standards

The AI Act places a strong emphasis on human rights, aligning with broader EU values such as democracy, dignity, and the protection of personal data. Its focus on fairness, transparency, non-discrimination, and accountability in AI systems is a major step toward ensuring AI development and deployment align with ethical standards. This approach makes the AI Act more aligned with human rights principles compared to some other regulations, which may focus primarily on safety or economic factors.

Penalties for Non-Compliance

The AI Act includes substantial penalties for non-compliance, with fines up to €30 million or 6% of a company’s global annual turnover, whichever is higher. These penalties are among the most severe for technology regulation and reinforce the importance of compliance. This enforcement mechanism makes the AI Act one of the most robust in terms of ensuring adherence to its provisions.

Continuous Evaluation and Updates

The AI Act includes provisions for ongoing review and updates to ensure it remains relevant as technology evolves. AI is a fast-moving field, and the regulation has been designed to be flexible enough to adapt to emerging developments, maintaining its relevance over time. This forward-looking approach makes it a more comprehensive and sustainable framework compared to others that may struggle to keep pace with AI innovation.

The EU’s AI Act is the most comprehensive AI regulation currently available due to its broad and detailed coverage, its robust ethical focus, and its global applicability. It combines clear risk-based regulation with detailed safety, accountability, and human rights provisions, addressing both the immediate challenges and the long-term concerns of AI technologies. While it sets a high bar for other jurisdictions, the ongoing challenge will be its enforcement, ensuring that the rules are effective across diverse applications and industries globally.

Explainable AI

Explainable AI (XAI) is an active area of AI research focused on making AI systems and their decision-making processes understandable to humans. As AI becomes increasingly embedded in everyday applications — ranging from healthcare and finance to autonomous vehicles and criminal justice — there is a growing need for transparency, so that users, stakeholders, and regulators can understand how and why AI systems reach certain conclusions. Explainable AI addresses this by providing tools and techniques that make AI decisions interpretable, reducing the “black box” nature often associated with complex models like deep learning. By enhancing transparency, XAI promotes trust, accountability, and ethical responsibility in AI applications, helping developers and organisations ensure that their systems align with legal requirements, societal expectations, and end-user needs.

There are several main approaches to achieving transparency and interpretability in AI systems. One key method is post-hoc explainability, where explanations are generated after a model has made its predictions, allowing developers to understand the reasoning without altering the model itself. Techniques in this category include visualisation tools, which highlight features or input areas that influenced a decision, and methods such as SHAP (Shapley Additive Explanations) and LIME (Local Interpretable Model-agnostic Explanations), which approximate how different inputs impact predictions.

Another approach is model-intrinsic interpretability, where the AI model is designed to be inherently understandable. This can involve using simpler, inherently interpretable algorithms, such as decision trees or linear regression, which naturally provide insights into their decision-making processes. Although these models may not achieve the same accuracy as complex deep learning models, they offer a clear and direct interpretation of how inputs lead to outputs.

Lastly, model simplification seeks to balance performance and interpretability by approximating a complex model with a simpler one that behaves similarly but is easier to understand. This may involve using rule-based systems or surrogate models that mimic the behaviour of a complex model, providing insights into its decisions without sacrificing interpretability. These approaches together form the foundation of explainable AI; however, a full discussion of the details of XAI is beyond the scope of this module.
