How to Build and Deploy Responsible, Trustworthy, and Ethical AI Systems

AI can improve productivity, support better services and unlock social benefit at scale. However, if it is deployed without good governance, it can automate discrimination, intensify inequality, undermine privacy and damage public trust. 

In Episode 7 of the Guardians of Data podcast, AI expert Tahir Latif argued that ethical and responsible AI cannot remain a collection of impressive slogans. Principles such as fairness, transparency, accountability and safety only matter if organisations can translate them into practical governance, day-to-day 
decision-making and evidence of responsible deployment. This is an urgent challenge because AI is being adopted faster than many organisations are maturing.  

Defining the Use Case 

Tahir says that businesses and public bodies often see AI as a strategy in itself:
an answer to cost reduction, efficiency, competitive advantage or service improvement. But AI is not a strategy. It is a tool. The question is not simply “Can we deploy this?” but “Why are we deploying it, who may be affected, what could go wrong, and how will we know whether it is working fairly?” 

A responsible AI programme starts with a clearly defined use case. Organisations should resist the temptation to apply “AI everywhere for everything”. A use case should explain the problem being solved, the people affected, the intended benefits, the lawful basis for processing data, the decision points where AI will be used and the limits of the system. This matters because the ethical risk of AI depends heavily on context. A tool that recommends music is very different from one that influences access to housing, healthcare, benefits, policing or credit. 

Strong Information Governance  

The next foundation a responsible AI programme is data quality. AI systems inherit the strengths and weaknesses of the data on which they are trained, tested and deployed. If data is biased, incomplete, unlawfully sourced, poorly classified or disconnected from its original purpose, the organisation is not innovating on solid ground; it is scaling risk. Ethical AI therefore requires strong information governance: clear data provenance, lawful and fair processing, purpose limitation, data minimisation, retention controls, accuracy checks and ongoing monitoring for bias or drift. 

Governance should begin at the ideation stage, not after a model has been purchased, built or released. Organisations need an AI governance framework that identifies ownership, risk appetite, approval routes, documentation standards, testing requirements, escalation processes and independent review. The UK’s regulatory approach highlights five relevant principles: safety, security and robustness; appropriate transparency and explainability; fairness; accountability and governance; and contestability and redress. The OECD AI Principles similarly emphasise human-centred, trustworthy AI that respects human rights and democratic values. 

The Human in the Loop 

Governance cannot be a paper exercise. Tahir warns against organisations claiming to have “human in the loop” oversight when the human does not understand what they are reviewing or lacks authority to stop a problematic deployment. Responsible oversight requires trained and empowered people. They must understand the limits of AI outputs, be able to challenge results, know when to escalate concerns and have permission to say no where risks are disproportionate. 

This is particularly important because AI systems can be fluent, persuasive and wrong. A confident output is not the same as a reliable one. AI often produces plausible answers rather than verifiable truth. That creates a risk of misplaced reliance, especially where users assume that machine-generated outputs must be objective or authoritative. Organisations should therefore build in validation, sampling, audit trails, performance monitoring and clear thresholds for human review. 

Transparency and Explainability 

Tahir says that central to trustworthy AI is transparency and explainability. But these terms must be understood realistically. Transparency means being open about when and how AI is used, what data it relies on, what role it plays in decisions and what rights affected individuals have. Explainability is about providing a meaningful account of how a system reaches or supports an outcome. In low-risk settings, a simple explanation may be enough. In high-impact contexts, such as credit, employment, welfare or healthcare, people need understandable reasons, routes to challenge and access to human review. 

Tahir’s mortgage example makes the point. If an applicant with a strong credit history, stable income and low debt is refused by an AI-assisted system, “computer says no” is not acceptable. The organisation must be able to explain the relevant factors, identify whether the decision was fair and provide a meaningful mechanism for contesting it. The more opaque the model, the stronger the justification must be for using it, especially where simpler and more interpretable methods would achieve the purpose. 

Privacy and data protection also sit at the heart of responsible AI. The healthcare example discussed in the podcast shows both the opportunity and the caution required. AI can assist radiographers by reviewing large volumes of labelled X-ray images quickly and accurately, helping clinicians identify patterns that may be difficult for the human eye to detect. But the same sector also illustrates why governance matters: patients must be able to trust that sensitive data is used lawfully, securely and proportionately, and that AI supports rather than replaces accountable clinical judgment. 

Lifecycle Management 

Tahir emphasise that AI risk does not end at product launch. Models can degrade, data can change, users can misuse outputs and social impacts may emerge over time. Organisations should monitor performance, fairness, security, complaints, incidents, and unintended consequences. They should also be prepared to suspend, retrain, restrict or retire systems that no longer meet legal, ethical or operational standards. 

Respecting Rights 

Copyright and training data add another ethical dimension. AI systems depend on data, but innovation cannot simply override the rights of creators, authors, artists and performers. Organisations should ask whether training data has been lawfully obtained, whether rights holders have been respected, whether outputs may reproduce protected material and whether transparency is owed to users or creators. Ethical AI is not only about avoiding biased outputs; it is also about respecting the labour and rights embedded in the data ecosystem. 

IG Officer Skills 

For information governance professionals, the message is clear: AI governance is not a side issue. It is becoming a core professional responsibility. The most valuable skills will include judgment, translation, evidence and humility.  

Judgment means asking whether a system is proportionate, fair, defensible and wise. Translation means communicating risk across technical, legal, governance and executive audiences. Evidence means documenting decisions, testing, approvals, safeguards and monitoring. Humility means recognising that AI is developing quickly and that continuous learning is essential. 

Tahir says that ultimately, building responsible, trustworthy and ethical AI systems is not about choosing between innovation and regulation. It is about designing the conditions for AI to serve people well. That means clear use cases, good data, meaningful accountability, trained humans, transparent explanations, privacy by design, challenge mechanisms and ongoing assurance. AI may be powered by technology, but trust is built by people, governance and the choices organisations make before, during and after deployment.

AI and Cyber Security 

In recent weeks, governments, regulators and cyber security professionals have been gripped by the emergence of Mythos, the powerful AI model developed by Anthropic. Touted as capable of identifying software vulnerabilities at a level that rivals some of the world’s most skilled human researchers, the model has generated excitement, concern and intense debate.   

Against this backdrop, our guest in Episode 11 of the podcast is an internationally renowned cybersecurity leader, educator and technology strategist, Caroline Wong

In this conversation, Caroline explains how cybercriminals are using AI to launch sophisticate cyber-attacks. We also discuss how organisations can use the same technology to strengthen their cyber defences. But this conversation goes beyond the technical. We discuss why trust is becoming the central battleground in cybersecurity, how deepfakes and AI-generated content are reshaping the way we verify information, and why human judgment remains critical despite rapid advances in automation. We also take a closer look at Mythos itself and what it means for the future of cybersecurity.

The last two years has seen a massive increase in AI deployment. Previously the domain of Science Fiction, AI is now everywhere – in our workplaces, our personal lives, and in the systems that shape society. From healthcare to security and law enforcement. But alongside the opportunities, there are some big risks: including lack of accuracy and transparency as well as bias and discrimination. 

In this episode, we dive into one of the biggest questions of our time: How do we build trustworthy and responsible AI systems? 

To help us answer this question, we are joined by someone who is right at the heart of the conversation. Tahir Latif is a distinguished expert on building responsible and transparent AI systems. He is the Global Practice Lead for Data Privacy & Responsible AI at Cognizant, one of the largest global professional services companies. Tahir has led complex privacy and AI programmes across multiple industry sectors both in the UK and globally. He is also the Chief AI and Governance Officer and board member at the Ethical AI Alliance, a not for profit body which promotes ethical standards in AI development. Tahir is the co-author of Data Privacy – A Practical Handbook on Governance and Operation.

In this conversation, we explore how to cut through the complexity of ethical AI, what the future holds, and most importantly, what practical steps IG professionals can take to succeed in this new landscape.

Home Office Acknowledges Racial and Gender Bias in UK Police Facial Recognition Technology

Facial recognition is often sold as a neutral, objective tool. But recent admissions from the UK government show just how fragile that claim really is.

New evidence has confirmed that facial recognition technology used by UK police is significantly more likely to misidentify people from certain demographic groups. The problem is not marginal, and it is not theoretical. It is already embedded in live policing.

A Systematic Pattern of Error

Independent testing commissioned by the Home Office found that false-positive rates increase dramatically depending on ethnicity, gender, and system settings.

At lower operating thresholds — where the software is configured to return more matches — the disparity becomes stark. White individuals were falsely matched at a rate of around 0.04%. For Asian individuals, the rate rose to approximately 4%. For Black individuals, it reached about 5.5%. The highest error rate was recorded among Black women, who were falsely matched close to 10% of the time.

The data highlights a striking imbalance: Asian and Black individuals were misidentified almost 100 times more frequently than white individuals, while women faced error rates roughly double those of men.

Why This Is Not an Abstract Risk

This technology is already in widespread use. Police forces rely on facial recognition to analyse CCTV footage, conduct retrospective searches across custody databases, and, in some cases, deploy live systems in public spaces.

The scale matters. Thousands of retrospective facial recognition searches are conducted each month. Even a low error rate, when multiplied across that volume, results in a significant number of people being wrongly flagged.

A false match can lead to questioning, surveillance, or police intervention. Even if officers ultimately decide not to act, the encounter itself can be intrusive, distressing, and damaging. These effects do not disappear simply because a human later overrides the system.

Bias, Thresholds, and Operational Reality

For years, facial recognition vendors and public authorities argued that bias could be controlled through careful configuration. In controlled conditions, stricter thresholds reduce error rates. But operational pressures often incentivise looser settings that generate more matches, even at the cost of accuracy.

The government’s own findings now confirm what critics have long warned: fairness is conditional. Bias does not vanish; it shifts depending on how the system is used.

The data also shows that demographic impacts overlap. Women, older people, and ethnic minorities are all more likely to be misidentified, with compounded effects for those who sit at multiple intersections.

Expansion Amid Fragile Trust

Despite these findings, the government is consulting on proposals to expand national facial recognition capability, including systems that could draw on large biometric datasets such as passport and driving licence records.

Ministers have pointed to plans to procure newer algorithms and to subject them to independent evaluation. While improved testing and oversight are essential, they do not answer the underlying question: should surveillance infrastructure be expanded while known structural risks remain unresolved?

Civil liberties groups and oversight bodies have described the findings as deeply concerning, warning that transparency, accountability, and public confidence are being strained by the rapid adoption of opaque technologies.

This Is a Governance Issue, Not Just a Technical One

Facial recognition is not simply a question of software performance. It is a question of how power is exercised and how risk is distributed.

When automated systems systematically misidentify certain groups, the consequences fall unevenly. Decisions about who is stopped, questioned, or monitored start to reflect the limitations of technology rather than evidence or behaviour.

Once such systems become normalised, rolling them back becomes difficult. That is why scrutiny matters now, not after expansion.

If technology is allowed to shape policing, the justice system, and public space, it must be subject to the highest standards of accountability, fairness, and democratic oversight.

These and other developments in the use of artificial intelligence, surveillance, and automated decision-making will be examined in detail in our AI Governance Practitioner Certificate training programme, which provides a practical and accessible overview of how AI systems are developed, deployed, and regulated, with particular attention to risk, bias, and accountability.
