### Ethical Theories and Principles 1. **What is Ethics?** - Ethics are shared principles distinguishing right from wrong and guide behavior in society. They are often not laws but can influence laws and are not always tied to religion. 2. **Normative Ethical Theories:** - Divided into three domains: - Theories of moral character (virtue ethics): What virtues should be promoted? - Theories of the good: What is morally valuable? - Theories of right obligation: What makes an action right or wrong? 3. **Applied Ethics:** - Applied ethics is about applying moral principles to real-world issues such as ICT ethics, bioethics, business ethics, and environmental ethics. - Examples of ethical dilemmas include bluffing during business negotiations or mercy killing in medical contexts. ### 21st Century Skills and ICT 4. **21st Century Skills:** - Life & Career: Focus on cross-cultural collaboration, bridging knowledge cultures, and ethical skills. - Learning & Innovation: Problem-solving, creativity, entrepreneurial and managerial skills. - Digital ICT Literacy: Data mining, self-branding, online sociality, etc. - Research & Publishing: Information gathering, data visualization, interdisciplinary skills. 5. **ICT and Digital Literacy:** - ICT enhances the ability to process and disseminate information. However, there is a risk of the "digital divide" between those who have access to ICT and those who don't. ### Industry 4.0 and 4IR (Fourth Industrial Revolution) 6. **Industry 4.0:** - Industry 4.0 marks the integration of technologies like cloud computing, AI, robotics, 3D printing, and IoT into manufacturing and other industries. - The Fourth Industrial Revolution (4IR) refers to this transformation, emphasizing automation, data, and human-machine interaction. 7. **Technologies in 4IR:** - AI, robotics, IoT, big data analytics, UAVs (drones), 5G technology, cybersecurity, blockchain, quantum technology, and smart homes. ### Ethical Issues in Emerging Technologies 8. **Big Data Ethics:** - Ethical concerns revolve around data privacy, consent, fairness, and algorithmic bias. Data scientists and analysts must manage these responsibly to avoid misuse and ensure fairness. 9. **Artificial Intelligence (AI) and Warfare:** - AI's role in warfare, including lethal autonomous weapons and robotic technologies, raises ethical questions about accountability and safety. 10. **Autonomous Vehicles and Drones:** - These technologies also present safety and privacy challenges, with questions about public safety and ethical responsibilities. 11. **Ethics of 5G Technology:** - The 5G debate centers on its benefits (enhancing performance, unlocking economic opportunities) versus its risks (health concerns due to electromagnetic exposure and environmental harm). ### Discussion Topics 12. **For Discussion:** - Ethical considerations surrounding AI, IoT, cyberattacks, robot partners, and the limitations of technologies like autonomous vehicles are crucial in understanding the broader ethical impact. ### 1. **Ownership and Copyright:** - **Copyright** laws are in place to protect the creators of software, artistic work, and other intellectual property (IP). It discusses the balance between the creator's rights and the public’s access to information. - There is a particular focus on *Open Source Software (OSS)*, which is freely available to the public, allowing users to modify and share it. However, using OSS in commercial products can have legal risks. - The **Public Domain** consists of works that are no longer under copyright protection, and *Fair Use* permits certain limited uses of copyrighted material for teaching, research, or commentary. ### 2. **Plagiarism and Piracy:**  - **Plagiarism** is using someone else's work without permission or proper attribution. The document emphasizes the need for clear citation practices to avoid this, even unintentionally. - **Piracy** refers to the unauthorized duplication and distribution of copyrighted materials, such as music, movies, or software. Anti-piracy measures include encryption and user-friendly paid alternatives. ### 3. **Ethics and Online Content:** - The ethical use of online resources extends beyond consumption, including the responsibility of those managing and monitoring web platforms. - Ethical dilemmas arise when navigating issues like **Online Privacy**, **Social Media Addiction**, and **Online Tracking** of users. The document highlights the balance between convenience, safety, and privacy online. ### 4. **Political Impacts and AI Biases:** - There is an exploration of the political implications of IT, including how online content influences public opinion and governance. - The document also discusses **bias in AI models**, where the lack of diverse data in training models can lead to skewed outcomes, making ethical AI development a critical issue. ### 1. **What is Artificial Intelligence (AI)?** - **AI Definition**: Artificial Intelligence (AI) refers to the development of computer systems that can perform tasks usually requiring human intelligence, such as decision-making, language understanding, visual perception, and problem-solving. - **Types of AI**: There are two main types: - **Narrow AI (Weak AI)**: Designed to perform a narrow task (e.g., facial recognition or internet searches). - **General AI (Strong AI)**: Capable of performing any intellectual task that a human can do. Currently, this level of AI does not exist. ### 2. **History of AI** - The field of AI has its roots in the mid-20th century, beginning with pioneers like Alan Turing, who proposed the "Turing Test" to measure a machine’s ability to exhibit intelligent behavior. - **Milestones** in AI history include: - Development of symbolic reasoning (1950s-60s) - Expert systems and machine learning advancements (1970s-80s) - Deep learning and neural networks breakthroughs (2000s-present) ### 3. **Components of AI**  - AI systems comprise several fundamental components: - **Machine Learning (ML)**: A method of data analysis that automates analytical model building. It's a core part of AI where computers learn from data without explicit programming. - **Neural Networks**: AI systems that mimic the human brain's neural structures to make sense of patterns and relationships in data. - **Natural Language Processing (NLP)**: Enables machines to understand and process human language. It is used in applications like chatbots and language translation. - **Robotics**: The integration of AI into physical machines that can interact with the world (e.g., self-driving cars or industrial robots). ### 4. **Branches of AI** - **Expert Systems**: AI that uses knowledge bases to make decisions. These systems are designed to solve specific problems within a domain (e.g., medical diagnosis). - **Speech and Language Processing**: AI techniques for processing human speech and language in real-time (e.g., voice-activated assistants like Siri). - **Vision Systems**: AI systems that can interpret and understand visual information from the world, similar to human sight. ### 5. **Applications of AI** - **Healthcare**: AI is revolutionizing the medical field with applications like diagnostic tools, personalized medicine, and robotic surgeries. - **Finance**: AI is used for fraud detection, algorithmic trading, and credit scoring. - **Manufacturing**: AI powers robotics, predictive maintenance, and automated quality control. - **Entertainment**: From video game design to personalized content recommendations (like Netflix), AI plays a major role in enhancing user experiences. - **Self-Driving Cars**: Autonomous vehicles rely on AI to navigate and make real-time decisions. ### 6. **Machine Learning** - **Supervised Learning**: A type of ML where the algorithm is trained on labeled data. The machine makes predictions and is corrected when wrong, iterating until accuracy improves. - **Unsupervised Learning**: The machine is given data without labels and must find patterns or relationships in the data. - **Reinforcement Learning**: The machine learns by interacting with its environment and receiving positive or negative feedback (e.g., in games or robotic movements). ### 7. **Deep Learning and Neural Networks**  - **Deep Learning**: A subset of ML involving neural networks with multiple layers, capable of learning from large datasets to recognize patterns or trends. It powers much of today’s advancements in AI. - **Convolutional Neural Networks (CNNs)**: Specialized for image recognition and processing. - **Recurrent Neural Networks (RNNs)**: Used for tasks involving sequential data, such as language translation and speech recognition. ### 8. **Ethical and Social Implications of AI** - **Bias in AI**: AI systems can inherit biases from the data they are trained on, leading to unfair or harmful outcomes. Ethical AI development aims to mitigate these biases. - **Job Displacement**: Automation through AI may lead to significant shifts in job markets, potentially displacing certain roles while creating new opportunities. - **Privacy Concerns**: AI systems, especially those involved in surveillance or personal data processing, raise important questions about privacy and data security. ### 9. **Challenges in AI Development** - **Data Quality**: AI systems are only as good as the data they are trained on. Poor or biased data can lead to unreliable AI outcomes. - **Computational Power**: Training large AI models requires massive computational resources, often limiting their accessibility to large organizations. - **Ethics and Governance**: Developing policies and regulations to ensure AI is used responsibly is an ongoing challenge. Ensuring transparency, fairness, and accountability in AI is critical. ### 10. **Future of AI** - **Artificial General Intelligence (AGI)**: Research is ongoing to develop AGI, which would match or exceed human intelligence across a wide range of tasks. - **AI in Everyday Life**: AI is expected to become more integrated into daily life, from smart home systems to personal AI assistants. - **Collaboration between Humans and AI**: Rather than replacing humans, AI is increasingly seen as a tool for enhancing human capabilities, working alongside people to solve complex problems. Ethic issue in Social media Professional Benefits When you want to watch a movie, you may check out movie ratings and user comments on IMDb before choosing a movie to buy.  Before you purchase a product on Amazon, you often read reviews posted by previous buyers to confirm the product will work as expected. In college, students often review websites where students post comments about professors before picking classes such as in Yellowtalk. You face similar situations when you enter the workforce. When you are looking for jobs, in many ways it is useful to think of yourself as a product on the market for potential employers to buy. Before people hire you for your next job, they are very likely to explore what others have to say about you in the digital world. They may go to LinkedIn to check if your previous employers and colleagues have great things to say about you. They may even check your social media activities and learn about your family and political inclinations. The stakes are high. Hence, it is important to carefully manage your presence in the digital world, so your digital presence helps you and does not adversely affect your chances of finding a new job or striking new alliances. Good reviews and connections on LinkedIn may prove to be more valuable than what you list about yourself on your resume. An important challenge for both fresh graduates and employers is the high uncertainty about the work ethic and professionalism of fresh graduates. Do you show up on time? Are you a team player or do you create disruptions on the team? Do you show initiative, or do you have to be pushed to complete every task? A school or college transcript does not reveal these details. LinkedIn reviews from internship employers or team coaches can help close this gap and be a critical asset as you get started in your career. A basic LinkedIn account is free and allows you to send emails to your connections on LinkedIn. To send messages to members you don’t know, you need to pay for a premium account. If you are interested in working at a company, you can check on LinkedIn to see if any of your friends are working there and message them politely to make them aware of your interest. If a suitable position opens, your friends may reach out to you and may even connect you with the hiring manager. In fact, if your LinkedIn profile looks strong, a new job is likely to find you rather than the other way around. Recruiters, particularly in fields such as Digital Information Technology, with demand for good talents constantly scour LinkedIn in search of candidates. Other than LinkedIn, you may also want to establish your presence on sites frequented by other professionals in your field. If you are a programmer, you may want a GitHub profile to showcase all the hobby programming work you have done. If you are technically proficient, you could answer questions on StackOverflow and build your online reputation. If you do gig work, sites like Upwork and Fiverr can help you create a repertoire of work and reviews. Personal Benefits People of all ages use social media for its benefits. Eg. I stay connected with their friends from high school through social media, decades after graduation via facebook or Ig The Surgeon General’s advisory identifies several benefits, including a sense of community for people with shared values, identities, abilities, and interests. Users get important information quickly and also use social media to express their opinions. Social media helps you sustain friendships online and organize social events easily. By giving you access to a wider community, social media can increase the diversity of your peer groups. If you need social support, social media increases the likelihood that you will find one close to your preferences. Most adolescents report that social media helps them feel more accepted, more supported, more creative, and more connected to what’s going on in their friends’ lives. Professional Risks Unfortunately, the benefits of social media come with several risks that are not present in face-to-face interactions. Comments made during personal interactions stay limited to the memories of those present at the time of the interaction. But comments made on social media are persistent and available for review potentially forever. Many employers don’t just look at professional websites like LinkedIn but also do a Google search of your name. Employers, particularly large employers, are very concerned about how their customers feel about them. Anything associated with you on social media that can be interpreted as being disagreeable, such as racist, homophobic, xenophobic, or misogynistic, even statements made as jokes, may come in the way of a great career opportunity. In contrast, a carefully curated online persona can have a positive and meaningful impact on both your career and life. Therefore, be careful before you share information online. Another risk of social media relates to how you spend your time and attention. How you spend your time during your school years to learn skills relevant to a career can have a disproportionate impact on your professional outcomes. The earlier you enter a career, the longer you can benefit from the income earned from the career. Unfortunately, teenagers are also eager for social validation. They may end up spending their time and attention on trying to look like social-media influencers with excellent physiques. They do this without considering that having a certain body structure may be a job requirement for influencers, but few people can make a living by just relying on their great physique. For most people, it would take far greater effort to maintain physique and acquire skills necessary to earn a living as models (social media influencers) than it would take to learn technology for a profitable career. Focusing your attention on learning skills (such as enterprise technologies introduced in this book) that can help you find a good job may be very valuable ultimately compared to maintaining influence on social media. Besides, it becomes increasingly difficult to create novelty and maintain influencer status. But careers in widely relevant skills such as Digital Information Technologies can easily last a lifetime. Tracking When you watch a TikTok video, not only do they know what you watched but also where you placed your finger when watching, how long you watched it, how many times you watched it, and how many similarly themed videos you watched. They know what time of the day you usually watch videos and how much time you spend on every session. They know whether you are stationary or driving when you watch videos. They know what you liked, disliked, followed, or commented on. They know who your friends are and what their viewing preferences are. This enables TikTok to build a profile about you, and it’s safe to assume that TikTok knows more about you and your innermost thoughts, likes, and dislikes than your teachers, doctors, parents, friends, and colleagues.  TikTok may even know more about you than you might be willing to acknowledge yourself. This information gives TikTok, and other social media companies who are similarly tracking your information, enormous leverage over you. You should not be surprised to see digital ads follow you around wherever you go on the Internet. Even if your partner searches for a new car on a laptop that is connected to your home router, you may soon begin to see car advertisements. It doesn’t take long for a search engine to figure out that two people are closely associated if they use the same home router. If your friend is interested in a car, car companies are willing to spend their dollars to influence you, too. Addiction Not surprisingly, social media companies are able to offer targeted advertisements to keep people glued to their platforms for hours. Teenagers and young adults are particularly susceptible to social media addiction. If you answer “Yes” to any behaviors such as those listed here, you may be suffering from this addiction. The good news is that social media addiction can be cured. While research results are limited at this time, several experts have shared their personal experiences on how they cured their own social media addictions. Setting rules and boundaries is a common theme. Here are a few suggestions based on these experiences: Create a social media “happy hour.” Designate a happy hour dedicated to social media and use it for social media engagement but eliminate social media activity outside this window. This limits doom scrolling where you spend hours scrolling through your accounts. For example, you may decide to spend 30 minutes in the evenings or after accomplishing a major task. Avoid social media during lonely or low times. The apps are likely to make you feel worse as you will end up comparing yourself to others. Instead, find ways to create in-person interactions by visiting a library to borrow books or engage in other activities—e.g., yoga studio, cycling, dancing, or other team sports. Disable notifications. Most social media apps hook you by notifying you of some event that promises excitement. This interferes with any serious activity. If you get notified of your friends’ dating adventures every five minutes, you are not likely to focus on your upcoming exams. Focus on what is in your best interests, not on what is in the social media companies’ best interests. Practice technology hygiene. Keep laptops and phones away from your bedroom at night to avoid disrupting your sleep. Visit friends and family when you want company. Cyberbullying The mobile Internet connected us to people, but it also connected us to their darker sides. Cyberbullying is a pattern of threatening, mocking, or demeaning posts about someone on social media apps or messaging platforms. Once limited to physical interactions, bullying can now easily become a pervasive and a permanent feature of our life, following us wherever we go. It is no longer confined to school playgrounds and toxic family gatherings. Here are a few forms of cyberbullying, according to UNICEF spreading lies about or posting embarrassing photos or videos of someone on social media; sending hurtful, abusive, or threatening messages, images, or videos via messaging platforms; impersonating someone and sending mean messages to others on their behalf or through fake accounts. If you are experiencing cyberbullying, please act immediately to avoid impacting your physical and mental health. Here are a few options to consider: hide or delete offensive posts; bring the cyberbullying to the attention of a trusted adult; unfriend or block bullies; alert your school counselors since they deal with cyberbullies regularly; delete the social media app where you are being bullied until the issue is addressed (This may be a temporary measure since you are likely to depend upon social media apps and messaging platforms as a source of information and a networking tool.); contact the help center of the social media app or the messaging platform where you are being bullied. (Social media companies are far more aware of cyberbullying now than they were a decade ago and are constantly developing new technology and offering help to thwart cyberbullying. The UNICEF website to stop cyberbullying lists the help centers of social media apps at the bottom of the page.) Online Predators Parents strongly discourage their children from getting close to strangers, but often give children access to the Internet, where strangers can contact them, talk to them, and share inappropriate content with them.  Someone pretending to be a sixteen-year-old girl may be a fifty-year- old man convicted of pedophilia. Unfortunately, the Internet offers anonymity, which can be a blessing as well as a curse. Online predators hang around in social media sites that are popular with children, pose as children to befriend them, and gain their trust over time before trying to take advantage of them in inappropriate ways. Here are a few things to keep in mind: never give your contact information (e.g., address or phone number) to people you meet online; never arrange to physically meet a person you have only met online; never share a picture or a video of yourself that has the potential to embarrass you publicly or to blackmail you; beware if someone uses excessive flattery; immediately alert trusted adults/school counselors/police if someone shares inappropriate content. Online Scammers There are many types of scams going on in the online world, including job offer scams, lottery scams, hitman scams, romance scams, disaster relief scams, grandparent scams, and others. Scammers can pose as FBI agents, bank officials, IRS agents, or sheriffs. In general, be skeptical of unsolicited communication asking for your financial or personal information. If some offer looks too good to be true, then it probably is. You can get more information about the current recommendations to defend against scammers by visiting the Federal Trade Commission’s website on scam defense. Echo Chambers or Confirming Your Biases As human beings, we tend to seek information that reinforces our preexisting beliefs. Echo chambers refer to groups that promote information that fits their conclusions and ignore information that does not. If you spend time on social media apps, you are likely to gravitate towards information that you agree with. Social media algorithms will then flood you with similar information to keep you engaged. If you are not careful, social media apps can then become echo chambers and confirm and solidify your biases. Unfortunately, this can prevent you from learning counterpoints to your opinions. Potentially, you may accept untrue information that reinforces your opinions. The Internet is full of fringe groups spouting fake news and rumors.  Over time, this leads people to move further away from the truth and reluctant to listen to opposing viewpoints. Social scientists believe that social media apps have contributed to the polarization we see in our world. To avoid getting into this trap, try to consciously reach out to people and groups with opposing opinions and try to understand what might be behind their opinions. It is generally not useful to label those who disagree with you in adversarial terms.

International Cyber Security Agreements: Some laws and agreements focus on international cooperation in combating cyber crimes and promoting cybersecurity best practices. Examples include the Budapest Convention on Cybercrime and bilateral cybersecurity. A threat is a potential violation of security and causes harm. A threat can be a malicious program, a natural disaster or a thief.  Vulnerability is a weakness of a system that is left unprotected. Systems that are vulnerable are exposed to threats. Threat is a possible danger that might exploit vulnerability; the actions that cause it to occur are the security attacks. Passive Attack: Aims to get information from the system but it does not affect the system resources. Passive attacks may analyze the traffic to find the nature of communication that is taking place, or, release the contents of the message to a person other than the intended receiver of the message. Passive attacks are difficult to detect because they do not involve any alteration of the data. Thus, the emphasis in dealing with passive attacks is on prevention rather than detection. Active attack: An active attack tries to alter the system resources or affect its operations. Active attack may modify the data or create false data. An active attack may be a masquerade (an entity pretends to be someone else), replay (capture events and replay them), modification of messages, and denial of service. Active attacks are difficult to prevent. However, an attempt is made to detect an active attack and recover from them. On Hardware: ▪could be due to a natural calamity like floods or earthquakes ▪ due to power related problems like power fluctuations etc.; ▪ or by destructive actions of a burglar. Software Attacks: ▪Harms data stored in Computer ▪Software attacks may be due to malicious software, or, due to hacking. ▪Malicious software or malware is a software code included into the system with a purpose to harm the system. ▪Hacking is the most common attack Commonly known as malware is a software that brings harm to a computer system. It can take the form of executable code, scripts, active content, and other software. It is commonly used for earning money illegally. It steals protected data, deletes documents or adds software not approved by a user. Definition: “A program that is inserted into a program, usually covertly, with the intent of compromising the confidentiality, integrity, or availability of the victim’s data, applications, or Operating system or otherwise annoying or disturbing the victim”.
