Ethical and legal issues in computing concern the responsible use of technology and the laws that govern it. For GCSE Computer Science, students must understand key UK legislation, intellectual property, privacy, and the broader social impact of computing — including environmental costs and the ethical questions raised by artificial intelligence.
Why does GCSE computing include ethics and law?
Computers have transformed how society works, communicates, and makes decisions. With that power come serious responsibilities. The DfE national curriculum requires students to "understand the risks" of technology and to be able to "evaluate the social, ethical and legal issues associated with computer science." This topic appears across all GCSE Computer Science specifications and accounts for a significant portion of examination marks at AQA, OCR, and Edexcel.
What are the key UK laws covering computing?
| Law | Year | What it covers |
|---|---|---|
| Computer Misuse Act | 1990 | Makes it illegal to (1) access a computer without authorisation, (2) access a computer intending to commit further offences, and (3) modify computer material without authorisation (including releasing malware) |
| Data Protection Act / UK GDPR | 2018 | Controls how organisations collect, store, and use personal data; gives individuals rights to access, correct, and delete their data |
| Copyright, Designs and Patents Act | 1988 | Protects creative works (software, music, images, text) from copying without the creator's permission |
| Regulation of Investigatory Powers Act | 2000 | Governs the interception of communications by government and law enforcement |
Computer Misuse Act in detail
The Computer Misuse Act 1990 (CMA) has three main offences:
- Unauthorised access — logging into someone else's account, even with guessed credentials. Maximum sentence: 2 years.
- Unauthorised access with intent — accessing a computer to commit further crime (e.g. fraud). Maximum sentence: 5 years.
- Unauthorised modification — deleting, changing, or encrypting someone else's data without permission; releasing malware. Maximum sentence: 10 years.
The CMA covers activities such as hacking, creating and distributing viruses, and using password-cracking tools on systems you do not own.
What are intellectual property rights?
Intellectual property (IP) refers to creations of the mind — software, music, images, films, and written content. In computing:
- Copyright is automatic upon creation. You do not need to register it. A software program is protected by copyright from the moment it is written.
- Copying software without a licence is illegal under the Copyright, Designs and Patents Act 1988.
- Open-source software is released under licences (e.g. MIT, GPL) that allow copying, modification, and redistribution — sometimes with conditions. Open-source is legal; pirated software is not.
- Creative Commons licences allow creators to specify how others may use their work (e.g. attribution required, non-commercial only).
What is the Data Protection Act and UK GDPR?
The UK General Data Protection Regulation (UK GDPR), implemented through the Data Protection Act 2018, governs the use of personal data. The eight data protection principles require that personal data must be:
- Processed lawfully, fairly, and transparently.
- Collected for specified, explicit, and legitimate purposes.
- Adequate, relevant, and limited to what is necessary.
- Accurate and kept up to date.
- Kept no longer than necessary.
- Processed securely (integrity and confidentiality).
- Not transferred to countries with weaker data protection without safeguards.
- Held accountable — organisations must demonstrate compliance.
Individuals have rights including the right to access their data, the right to correction, and the right to erasure ("right to be forgotten").
What are the ethical issues raised by AI?
Artificial intelligence raises ethical questions that do not have simple technical answers:
| Ethical issue | Description |
|---|---|
| Bias and fairness | AI trained on biased data produces biased outputs. Facial recognition systems have shown higher error rates for darker-skinned individuals — a real-world harm when used in policing or hiring. |
| Accountability | If an AI makes a wrong decision (e.g. denying a loan, misidentifying a suspect), who is responsible? The developer? The user? The organisation deploying it? |
| Privacy | AI systems trained on personal data, or used for surveillance (facial recognition in public spaces), raise significant privacy concerns. |
| Employment | Automation and AI may displace jobs — self-checkout machines, automated customer service, and AI-driven logistics have already reduced some categories of employment. |
| Autonomous weapons | AI decision-making in military contexts — who decides when a weapon fires — is a major ongoing ethical debate. |
What are the environmental impacts of computing?
Computing has a substantial environmental footprint that is often invisible to users:
- Energy use of data centres — large data centres consume enormous amounts of electricity (estimated 1–2% of global electricity consumption). Cooling alone accounts for a significant proportion of this.
- Manufacturing emissions — producing a laptop requires significant energy and rare earth materials; smartphone manufacturing is particularly resource-intensive.
- E-waste — discarded electronics contain toxic materials (lead, mercury, cadmium) that require careful disposal. The UK generates approximately 1.1 million tonnes of e-waste per year.
- Internet traffic — streaming video, cloud storage, and AI model training all require data centre processing power that has a carbon cost.
Positive environmental uses of computing include climate modelling, smart energy grids, precision agriculture, and remote working reducing commuter emissions.
Frequently asked questions
Is it illegal to look at hacking tutorials online?
Reading about hacking techniques is not itself illegal in the UK. However, applying those techniques to any computer system you do not own and have not been given explicit permission to test is a criminal offence under the Computer Misuse Act, regardless of your motivation. Organisations such as GCHQ provide legitimate pathways for those interested in cyber security — including the UK Cyber Security Challenge — where skills are tested in safe, legal environments.
What is the difference between copyright and plagiarism?
Copyright is a legal concept: copying protected work without permission is illegal. Plagiarism is an academic concept: presenting someone else's work as your own without attribution, even if the copying is technically legal (e.g. copying from a public domain work). Copyright infringement can result in criminal prosecution or civil damages. Plagiarism typically results in academic consequences (failing a coursework, exclusion). Both apply to software: copying code without permission may break copyright law; submitting copied code as your own coursework is plagiarism.
What does "open source" mean and is it free?
Open source means the source code is publicly available and can be viewed, modified, and distributed. "Free" in the open-source context usually means "free as in freedom" (freedom to use, study, modify, share) rather than necessarily "free as in no cost." Some open-source licences (e.g. GPL) require that any modified versions are also released as open source. Others (e.g. MIT) allow incorporating code into proprietary software. Open-source software is legal; the specific licence governs what you may do with it.
What is algorithmic bias and why does it matter?
Algorithmic bias occurs when a computational system systematically produces unfair outcomes for certain groups of people. It typically arises from biased training data (historical data that reflects past discrimination) or from how a problem is defined. A hiring algorithm trained on past hiring decisions may perpetuate historical gender or racial biases — not because the algorithm intends to discriminate, but because it learned from data that reflected discrimination. Algorithmic bias matters because AI decisions increasingly affect access to jobs, loans, medical diagnoses, and the criminal justice system.
