5.1 Personal data Personal data is any data that relates to you and your identity. This includes data such as: •Name •Address •Telephone number •Email address •Bank details •Medical records •Salary •Political opinions You should be very careful about revealing any of your personal data! By revealing personal data to another, especially online, you are exposing yourself to dangers such as identity theft, fraud, bullying and blackmail. These types of dangers can be issues that arise as a result of revealing more personal thoughts and feelings to those that can use them against you. It is a more sinister viewpoint to take, but the moment you reveal any personal data to another, you are providing them with the potential to harm you or your identity. This isn't to say you should never speak to another, especially those unknown online, just understand how to recognise a danger and how to keep your identity secure. To keep yourself safe in your daily life, you are likely to have been taught to take measures such as locking doors, not talking to strangers and not venturing into unsafe areas. However, when many people go online, they relax their safety measures, perhaps because they are in the comfort of their own home, so do not think anything negative will happen. Many people that use the internet are genuine, but knowing how to detect the few that aren't is important. There are several guidelines for you to be aware of to keep your personal data confidential: •Have strong passwords set on any account that holds personal data. Stronger passwords include characters, numbers and symbols and are not a recognisable word. •Encrypt (scramble text so that it cannot be read without a decryption key) any personal data that you store on your computer. •Have a firewall present, scanning incoming and outgoing data from your computer system. •Regularly scan your computer with preventative software, such as an anti-virus package, that is used to identify a virus on a computer and remove it. •Make use of any biometric devices (devices that measures a person's biological data, such as thumbprints), that are built into technology. •Only visit and provide data to websites that are a trusted source. •Do not open any email attachments from a sender you do not recognise. •Check the URL attached to any link requesting data to see if it is genuine. •Be cautious about any pictures or opinions that you post or send to people. •Remove data about your location that is normally attached to your photos and videos that you may post, such as geotags. •Do not become friends on social networking sites with people you do not know. •Set all the privacy controls to the most secure setting that are available on social media accounts. •Report and block any suspicious user. •Use a nickname or pseudonym when using the internet for entertainment, for example, playing games. •If it is possible, use a virtual private network (VPN), an encrypted connection that can be used to send data more securely across a network. The ways in which some of these guidelines can be used in more detail will be explored throughout this chapter.

Revealing personal data can lead to threats like identity theft, fraud, bullying, and blackmail. 1.Identity Theft Definition: Identity theft occurs when someone steals your personal information and uses it without your permission. This can include your name, Social Security number, or bank details. Example: If someone gets your Social Security number, they could open a credit card in your name and run up bills that you would have to pay. 2.Fraud Definition: Fraud is when someone deceives another person to gain something of value, like money or personal information. This is often done through lies or tricks. Example: A person might call you pretending to be from your bank and tell you that you need to confirm your account details. If you give them your information, they may steal your money. 3. Bullying Definition: Bullying is when someone repeatedly hurts, threatens, or picks on another person. This can happen in person or online (cyberbullying). Example: If someone sends hurtful messages or spreads rumors about you on social media, that’s a form of bullying. 4. Blackmail Definition: Blackmail is when someone threatens to reveal harmful or embarrassing information about you unless you give them something they want, usually money or favors. Example: If someone takes a private photo of you and threatens to share it unless you pay them, that’s blackmail. Summary Identity Theft: Stealing personal information for illegal use. Fraud: Deceiving someone for personal gain. Bullying: Repeatedly hurting or threatening someone. Blackmail: Threatening to expose information unless demands are met. Understanding these terms helps you recognize and protect yourself from potential dangers in both real life and online. If you see any signs of these actions happening, it’s important to talk to a trusted adult or authority figure. There are several guidelines for you to be aware of to keep your personal data confidential: •Have strong passwords set on any account that holds personal data. Stronger passwords include characters, numbers and symbols and are not a recognisable word. •Encrypt (scramble text so that it cannot be read without a decryption key) any personal data that you store on your computer. •Have a firewall present, scanning incoming and outgoing data from your computer system. firewall : a security measure that can be implemented to monitor traffic into and out of a computer and prevent external users gaining unauthorised access to a computer system. A firewall is a security measure that helps protect a computer system by monitoring and controlling the traffic that comes into and goes out of the system. Think of it as a barrier between your computer and the outside world. It prevents unauthorized users from accessing your computer while allowing authorized traffic to pass through. •Regularly scan your computer with preventative software, such as an anti-virus package, that is used to identify a virus on a computer and remove it. Anti-virus: software that is used to identify a virus on a computer and remove it •Make use of any biometric devices (devices that measures a person's biological data, such as thumbprints), that are built into technology. biometric devices: Unique physical characteristic of a person that can be used by a computer for identification purposes. https://www.aratek.co/news/biometric-devices-definition-and-examples Biometric devices are tools that use unique physical characteristics of a person for identification purposes. This means they can recognize who you are based on features that are unique to you. Here are some examples of biometric characteristics: Fingerprint Recognition, Facial Recognition, Voice Recognition •Only visit and provide data to websites that are a trusted source. •Do not open any email attachments from a sender you do not recognise. •Check the URL attached to any link requesting data to see if it is genuine. •Be cautious about any pictures or opinions that you post or send to people. •Remove data about your location that is normally attached to your photos and videos that you may post, such as geotags. Geotag: an electronic tag that assigns a geographical location A geotag is an electronic tag that assigns a specific geographical location to a piece of information, like a photo or a video. Geotags can help people understand where a photo was taken or where an event occurred, making it easier to organize and find information based on location. •Do not become friends on social networking sites with people you do not know. •Set all the privacy controls to the most secure setting that are available on social media accounts. •Report and block any suspicious user. •Use a nickname or pseudonym when using the internet for entertainment, for example, playing games. •If it is possible, use a virtual private network (VPN), an encrypted connection that can be used to send data more securely across a network. Virtual private network (VPN) : an encrypted connection that can be used to send data more securely across a network A Virtual Private Network (VPN) is a special way to connect to the internet that keeps your information safe. Imagine you are sending a secret message to a friend. You want to make sure no one else can read it while it travels. A VPN helps you do just that! It creates an encrypted connection, which means it turns your message into a code that only your friend can understand Example: Public Wi-Fi Safety: When you use public Wi-Fi, like in a café, your data can be easily accessed by hackers. If you connect to a VPN while using that public Wi-Fi, your data is encrypted, making it much harder for anyone to steal your information.

CrossFi" generally refers to the intersection of Cross-Chain Finance and DeFi (Decentralized Finance), enabling seamless financial interactions across multiple blockchain networks. It allows users to move assets, trade, lend, and borrow across different chains without relying on centralized intermediaries. Key Features of CrossFi: Cross-Chain Asset Transfers – Users can transfer assets between different blockchains using interoperability protocols like bridges and wrapped tokens. Liquidity Aggregation – Combines liquidity from multiple chains to enhance trading efficiency and reduce slippage. Interoperability Solutions – Uses technologies like Polkadot, Cosmos IBC, LayerZero, and ThorChain to facilitate blockchain communication. Multi-Chain Yield Farming & Staking – Allows users to stake and earn rewards across various chains. Security & Decentralization – Many CrossFi solutions use decentralized oracles, multi-party computation (MPC), and ZK-rollups to enhance security. Popular CrossFi Projects: ThorChain (RUNE): A cross-chain liquidity network that allows native asset swaps. Synapse Protocol: Provides cross-chain bridging and interoperability solutions. LayerZero: A cross-chain messaging protocol enabling omnichain applications. Cosmos (ATOM): Uses the Inter-Blockchain Communication (IBC) protocol for seamless transactions. Why CrossFi Matters? Eliminates blockchain silos and enhances DeFi adoption. Reduces reliance on centralized exchanges for cross-chain trading. Enhances user experience by allowing smooth movement of assets across chains. include blockchain technology questions

The LMS has been an essential tool in curriculum design and development and in organizing factors that motivate student learning, especially in online distance learning. However, an LMS can be used in blended, hybrid, and in-class delivery modes. It is a software application designed to help in the administration of courses for both students and instructors. Such systems have been designed for use in learning and teaching activities (Chung et al., 2012). They also provide a variety of interaction methods between instructors and learners to facilitate the learning process better, You must remember well-designed LMS could also help improve student skills, such as effective online learning and self-direction (Norouzi, 2014). Students could use the system to enhance performance (perceived usefulness), and they could use such systems with little effort (perceived ease of use) (Venkatesh & Davis, 2000). A majority of higher education institutions have incorporated LMS systems; they have been used in university systems by schools, faculty members, and instructors (Klobas & McGill,. 2010), Because so much of higher education has been focused on course delivery Chapter3 INSTRUCTIONAL DELIVERY SYSTEMS AND EDUCATIONAL TECHNOLOGY i 71 in a physical classroom, the implementation of an LYS has a;ded institutons in transitioning to new online universe of curriculum de!ivery (Georgou!i, & Guerre. 2NS). Repositories, central databases, and online meeting 'oations are all characteristcs of a management system. As a concept, a 'earning management system is a broad idea and an example of technology's inabifity to be specific in terms of a definition. Several requirements a generat overview of what constitutes a leaming management system, such as those listed above Finally, end-user access is also a part of a learning management system with various levels being set up by security. For example, students have read-onty access, faculty members have read and write access, and technical staff has complete access for support and administrative duties (Graf & Chien, 2009). At its core, a learning management system contains internal or Web-based support and management for numerous aspects of learning and teaching (Hiary & Abu-Shawar, 2009). This allows access from numerous locales, usually on a 24-hour basis. When looking at a university or college, this concept begins to grow greatly depending on the organization's size and scope; department, and degree program. Leaming management systems also go by other names such as course management systems, and their use goes beyond higher education institutions to include businesses and individual instructors. Meis)ar-Tal, Kurtz, and Pieterse (2012) mentioned three primary purposes of an CMS. They include the following: 1. to provide students with digital learning materials; 2. to employ interactive learning activities with students in the forums; and 3. to manage the course and the learners. Faculty members who use an LMS to make available lecture notes and other classroom resources for their face-to-face class create a web-enhanced classroom experience. Regardless of its usage, requirements for classification as a learning management system include several key concepts like the availability of assets over networks, providing hosting, administration. and support. With the requirements set, utilization becomes the focal point. A fully utilized learning management system looks at use at the student level, faculty level, and administration level. proper utilization of learning management systems should mirror traditional higher education goals, enhancing students' experiences. For learninä management systems, this creates a central hub for a class activity. For some classes, all activities work in the learning management system, while others only use its resources for select activities.
