1. Chapter at a glance
- Digital footprint is the trail of data created by online activities; it includes active (intentional) and passive (unintentional) types and cannot be fully erased.
- A netizen must follow net etiquettes (ethical, respectful, responsible), communication etiquettes (precise, polite, credible) and social media etiquettes (secure, reliable).
- Intellectual Property Rights (IPR) protect original works through copyright, patent and trademark; violations include plagiarism, copyright infringement and trademark infringement.
- Free and Open Source Software (FOSS) and public licences such as GNU GPL and Creative Commons (CC) allow sharing, modification and redistribution while preserving rights.
- Cyber crimes include hacking (ethical/white-hat vs non-ethical/black-hat), phishing, identity theft and ransomware; they target individuals, organisations or systems.
- The Information Technology Act, 2000 (amended 2008) provides the legal framework for electronic records, digital signatures and penalties for cyber offences.
- Excessive screen time affects physical and mental health; ergonomics and correct posture help reduce strain, eye fatigue and related problems.
2. Key terms and definitions
- Digital footprint: Trail of data reflecting online activities (websites visited, emails sent, information submitted) along with IP address, location and device details.

- Passive digital footprint: Data generated unintentionally (browsing history, cookies, location data when visiting sites or using apps).
- Netizen (digital citizen): Anyone who uses digital technology along with the Internet and practices safe, ethical and legal use.
- Net etiquettes: Proper online manners covering ethical behaviour (no copyright violation, share verified expertise), respect for privacy and diversity, and responsibility (avoid cyber bullying and trolling).
- Communication etiquettes: Rules for email, chat, forums etc. — be precise (respect time and data limits), polite and credible.
- Social media etiquettes: Rules for platforms — choose strong passwords, know contacts, beware of fake information, think before uploading.
- Sensitive data: Information that can cause substantial harm, embarrassment or unfairness if breached (biometric, health, financial, personal documents).
- Intellectual Property (IP): Inventions, literary/artistic works, designs, symbols, names and logos whose ownership lies with the creator.
- Copyright: Legal rights automatically granted to creators for original works (writing, images, audio, video, software); includes rights to reproduce, distribute and display.
- Patent: Exclusive right granted (after application) to an inventor to prevent others from using, selling or distributing the invention for 20 years.
- Trademark: Visual symbol, word, name, design or slogan that distinguishes one brand/commercial enterprise from others.
- Plagiarism: Presenting someone else’s idea or work as one’s own without citing the source.
- Copyright infringement: Using another person’s work without permission or without paying for it when required.
- Trademark infringement: Unauthorised use of another’s registered trademark on products/services.
- FOSS (Free and Open Source Software): Software that is free to use, access, modify and distribute; source code is openly available (examples: Linux, LibreOffice, Firefox).
- GNU GPL: Popular free software licence that grants rights to run, study, share, modify and redistribute software while requiring the same freedoms for derivative works.
- Creative Commons (CC): Public licence for creative works (websites, music, literature) allowing sharing, use and modification under specified conditions.

- Hacking: Unauthorised access to a computer, network or digital system.
- White-hat (ethical) hacker: Hacker who exploits vulnerabilities with permission to improve security.
- Black-hat (cracker) hacker: Hacker who gains unauthorised access for malicious purposes (data theft, damage).

- Identity theft: Unlawful use of a victim’s personal data (demographic, financial, Aadhaar, PAN etc.) for fraud or monetary gain.
- Ransomware: Malware that encrypts or blocks access to data and demands payment (ransom) for restoration.
- Ergonomics: Science of designing workplaces, furniture and equipment so that use is safe and comfortable, reducing fatigue and injury.
3. Syntax and constructs
No programming syntax, functions, methods or code constructs are taught in this chapter.
4. Algorithms and worked logic
No algorithms, procedures involving code or step-by-step computational logic are present in the chapter.
5. Common errors and exam pitfalls
- Confusing active vs passive digital footprints (active = intentional submission; passive = automatic generation).
- Treating plagiarism and copyright infringement as identical; plagiarism is failure to cite, while infringement is use without permission/payment.
- Mixing white-hat (ethical, authorised) and black-hat (malicious, unauthorised) hackers.
- Assuming anything on the Internet is free to use; students lose marks for not stating that even openly available content requires checking copyright status.
- Forgetting that deleted online content may still exist on servers or in others’ digital footprints.
- Listing safety measures without mentioning regular backups, strong/unique passwords, updated antivirus and avoiding pirated/untrusted sources.
- Omitting that the IT Act 2000 (amended 2008) covers electronic records, digital signatures and establishes the Cyber Appellate Tribunal.
