is an unlawful activity where fake websites or emails that look original or authentic are presented to the user to fraudulently collect sensitive and personal details, particularly usernames, passwords, banking and credit card details. The most common phishing method is through email spoofing where a fake or forged email address is used and the user presumes it to be from an authentic source. So you might get an email from an address that looks similar to your bank or educational institution, asking for your information, but if you look carefully you will see their URL address is fake. They will often use logo’s of the original, making them difficult to detect from the real! Phishing attempts through phone calls or text messages are also common these days. (A) Identity Theft Identity thieves increasingly use personal information stolen from computers or computer networks, to commit fraud by using the data gained unlawfully. A user’s identifiable personal data like demographic details, email ID, banking credentials, passport, PAN, Aadhaar number and various such personal data are stolen and misused by the hacker on behalf of the victim. This is one type of phishing attack where the intention is largely for monetary gain. There can be many ways in which the criminal takes advantage of an individual’s stolen identity. Given below are a few examples: • Financial identity theft: when the stolen identity is used for financial gain. • Criminal identity theft: criminals use a victim’s stolen identity to avoid detection of their true identity. • Medical identity theft: criminals can seek medical drugs or treatment using a stolen identity. Beware !! Accepting links from untrusted emails can be hazardous, as they may potentially contain a virus or link to malicious website. We should ensure to open any email link or attachment only when it is from a trusted source and doesn’t look doubtful. Ch 11.indd 240 08-Apr-19 12:32:00 PM 2020-21 Societal Impact 241 11.5.3 Ransomware This is another kind of cyber crime where the attacker gains access to the computer and blocks the user from accessing, usually by encrypting the data. The attacker blackmails the victim to pay for getting access to the data, or sometimes threaten to publish personal and sensitive information or photographs unless a ransom is paid. Ransomware can get downloaded when the users visit any malicious or unsecure websites or download software from doubtful repositories. Some ransomware are sent as email attachments in spam mails. It can also reach our system when we click on a malicious advertisement on the Internet. 11.5.4 Combatting and Preventing Cyber Crime The challenges of cyber crime can be mitigated with the twin approach of being alert and taking legal help. Following points can be considered as safety measures to reduce the risk of cyber crime: • Take regular backup of important data • Use an antivirus software and keep it updated always • Avoid installing pirated software. Always download software from known and secure (HTTPS) sites • Always update the system software which include the Internet browser and other application software • Do not visit or download anything from untrusted websites • Usually the browser alerts users about doubtful websites whose security certificate could not be verified; avoid visiting such sites • Use strong password for web login, and change it periodically. Do not use same password for all the websites. Use different combinations of alphanumeric characters including special characters. Ignore common words or names in password • While using someone else’s computer, don’t allow browser to save password or auto fill data, and try to browse in your private browser window Activity 11.6 Explore and find out how to file a complaint with the cyber cell in your area. Ch 11.indd 241 08-Apr-19 12:32:00 PM 2020-21 242 Computer Science – Class xi • For an unknown site, do not agree to use cookies when asked for, through a Yes/No option. • Perform online transaction like shopping, ticketing, and other such services only through well-known and secure sites • Always secure wireless network at home with strong password and regularly change it. 11.6 Indian Information Technology Act (IT Act) With the growth of Internet, many cases of cyber crimes, frauds, cyber attacks and cyber bullying are reported. The nature of fraudulent activities and crimes keeps changing. To deal with such menaces, many countries have come up with legal measures for protection of sensitive personal data and to safeguard the rights of Internet users. The Government of India’s Information Technology Act, 2000 (also known as IT Act), amended in 2008, provides guidelines to the user on the processing, storage and transmission of sensitive information. In many Indian states, there are cyber cells in police stations where one can report any cyber crime. The act provides legal framework for electronic governance by giving recognition to electronic records and digital signatures. The act outlines cyber crimes and penalties for them. Cyber Appellate Tribunal has been established to resolve disputes arising from cyber crime, such as tampering with computer source documents, hacking the computer system, using password of another person, publishing sensitive personal data of others without their consent, etc. The act is needed so that people can perform transactions over the Internet through credit cards without fear of misuse. Not only people, the act empowers government departments also to accept filing, creation and storage of official documents in the digital format. 11.7 Impact on Health As digital technologies have penetrated into different fields, we are spending more time in front of screens, be it mobile, laptop, desktop, television, gaming console, Do you follow precautions to stay healthy — physically, mentally as well as emotionally while using digital technologies? Think and Reflect Digital signatures are the digital equivalent of a paper certificate. Digital signatures work on a unique digital ID issued by a Certified Authority (CA) to the user. Signing a document digitally means attaching that user's identity which can be used to authenticate. A licensed CA who has been granted a license to issue it under section 24 of the indian IT-Act 2000, can issue the digital signature. Ch 11.indd 242 08-Apr-19 12:32:00 PM 2020-21 Societal Impact 243 music or sound device. But interacting in an improper posture can be bad for us — both physically, and mentally. Besides, spending too much time on Internet can be addictive and can have a negative impact on our physical and psychological well being. However, these health concerns can be addressed to some extent by taking care of the way we position such devices and the way we position our posture. Ergonomics is a branch of science that deals with designing or arranging workplaces including the furniture, equipments and systems so that it becomes safe and comfortable for the user. Ergonomics helps us in reducing the strain on our bodies — including the fatigue and injuries due to prolonged use. When we continuously look at the screen for watching, typing, chatting or playing games, our eyes are continuously exposed to the glare coming from the screens. Looking at small handheld devices makes it worse. Eye strain is a symptom commonly complained by users of digital devices. Device Safety: Ensures Good Health of a Computer System √ Regularly clean it to keep the dust off. Use a liquid solution specifically formulated for the cleaning of electronic screens. √ Wipe monitor’s screen often using the regular microfibre soft cloth (the one used for spectacles). √ Keep it away from direct heat, sunlight and put it in a room with enough ventilation for air circulation. √ Do not eat food or drink over the keyboard. Food crumbs that fall into the gaps between the keys or spilled over liquid can cause issues to the devices.

Figure 11.5 shows the posture to be maintained in order to avoid fatigue caused due to prolonged use of computer system and other digital devices. However, to get rid of dry, watering, or itchy eyes, it is better to periodically focus on distant objects, and take a break for outdoor activities. Bad posture, backaches, neck and shoulder pains can be prevented by arranging the workspace as recommended by ergonomics. Overuse of keyboards (be it physical keyboard or touchscreen-based virtual keyboard) not aligned ergonomically, can give rise to a painful condition of wrists and fingers, and may require medical help in the long run. Stress, physical fatigue and obesity are the other related impacts the body may face if one spends too much time using digital devices. Maintain a Balance!! Enjoy the exciting world of digital devices in tandem with other pursuits of thrilling sports and hobbies. Online friends are good, but spending time with friends in real life is very fulfilling. Often the wholesome nature of real interactions cannot be compared to just online social networking. Summary • Digital footprint is the trail of data we leave behind when we visit any website (or use any online application or portal) to fill-in data or perform any transaction. • A user of digital technology needs to follow certain etiquettes like net-etiquettes, communicationetiquettes and social media-etiquettes. • Net-etiquette includes avoiding copyright violations, respecting privacy and diversity of users, and avoiding cyber bullies and cyber trolls, besides sharing of expertise. • Communication-etiquette requires us to be precise and polite in our conversation so that we remain credible through our remarks and comments. • While using social media, one needs to take care of security through password, be aware of fake information and be careful while befriending unknowns. Care must be taken while sharing anything on social media as it may create havoc if being mishandled, particularly our personal, sensitive information. • Intellectual Property Rights (IPR) help in data protection through copyrights, patents and trademarks. There are both ethical and legal Ch 11.indd 244 08-Apr-19 12:32:01 PM 2020-21 Societal Impact 245 aspects of violating IPR. A good digital citizen should avoid plagiarism, copyright infringement and trademark infringement. • Certain software are made available for free public access. Free and Open Source Software (FOSS) allow users to not only access but also to modify (or improve) them. • Cyber crimes include various criminal activities carried out to steal data or to break down important services. These include hacking, spreading viruses or malware, sending phishing or fraudulent emails, ransomware, etc. • Excessive usage of digital devices has a negative impact on our physical as well as psychological well-being. Ergonomic positioning of devices as well as our posture are important. Exercise 1. After practicals, Atharv left the computer laboratory but forgot to sign off from his email account.

11.5 Cyber Crime Criminal activities
11.5 Cyber Crime Criminal activities
or offences carried out in a digital environment can be considered as cyber crime. In such crimes, either the computer itself is the target or the computer is used as a tool to commit a crime. Cyber crimes are carried out against either an individual, or a group, or an organisation or even against a country, with the intent to directly or indirectly cause physical harm, financial loss or mental harassment. A cyber criminal attacks a computer or a network to reach other computers in order to disable or damage data or services. Apart from this, a cyber criminal may spread viruses and other malwares in order to steal private and confidential data for blackmailing and extortion. A computer virus is some lines of malicious code that can copy itself and can have detrimental effect on the computers, by destroying data or corrupting the system. Similarly, malware is a software designed to specifically gain unauthorised access to computer systems. The nature of criminal activities are alarmingly increasing day-by-day, with frequent reports of hacking, ransomware attacks, denial-of-service, phishing, email fraud, banking fraud and identity theft. 11.5.1 Hacking Hacking is the act of unauthorised access to a computer, computer network or any digital system. Hackers usually have technical expertise of the hardware and software. They look for bugs to exploit and break into the system. Hacking, when done with a positive intent, is called ethical hacking. Such ethical hackers are known as white hat hackers. They are specialists in exploring any vulnerability or loophole during testing of the software. Thus, they help in improving the security of a software. An ethical hacker may exploit a website in order to discover its security loopholes or vulnerabilities. He then reports his findings to the website owner. Thus, ethical hacking is actually preparing the owner against any cyber attack. A non-ethical hacker is the one who tries to gain unauthorised access to computers or networks in order to steal sensitive data with the intent to damage or bring down systems. They are called black hat hackers Remember!! Cyber crime is defined as a crime in which computer is the medium of crime (hacking, phishing, spamming), or the computer is used as a tool to commit crimes (extortion, data breaches, theft). Activity 11.5 How can you unsubscribe from a mail group or block an email sender? Ch 11.indd 239 08-Apr-19 12:32:00 PM 2020-21 240 Computer Science – Class xi or crackers. Their primary focus is on security cracking and data stealing. They use their skill for illegal or malicious purposes. Such hackers try to break through system securities for identity theft, monetary gain, to bring a competitor or rival site down, to leak sensitive information, etc. 11.5.2 Phishing and Fraud Emails Phishing is an unlawful activity where fake websites or emails that look original or authentic are presented to the user to fraudulently collect sensitive and personal details, particularly usernames, passwords, banking and credit card details. The most common phishing method is through email spoofing where a fake or forged email address is used and the user presumes it to be from an authentic source. So you might get an email from an address that looks similar to your bank or educational institution, asking for your information, but if you look carefully you will see their URL address is fake. They will often use logo’s of the original, making them difficult to detect from the real! Phishing attempts through phone calls or text messages are also common these days. (A) Identity Theft Identity thieves increasingly use personal information stolen from computers or computer networks, to commit fraud by using the data gained unlawfully. A user’s identifiable personal data like demographic details, email ID, banking credentials, passport, PAN, Aadhaar number and various such personal data are stolen and misused by the hacker on behalf of the victim. This is one type of phishing attack where the intention is largely for monetary gain. There can be many ways in which the criminal takes advantage of an individual’s stolen identity. Given below are a few examples: • Financial identity theft: when the stolen identity is used for financial gain. • Criminal identity theft: criminals use a victim’s stolen identity to avoid detection of their true identity. • Medical identity theft: criminals can seek medical drugs or treatment using a stolen identity. Beware !! Accepting links from untrusted emails can be hazardous, as they may potentially contain a virus or link to malicious website. We should ensure to open any email link or attachment only when it is from a trusted source and doesn’t look doubtful. Ch 11.indd 240 08-Apr-19 12:32:00 PM 2020-21 Societal Impact
(A) Plagiarism
(A) Plagiarism
With the availability of Internet, we can instantly copy or share text, pictures and videos. Presenting someone else’s idea or work as one’s own idea or work is called plagiarism. If we copy some contents from Internet, but do not mention the source or the original creator, then it is considered as an act of plagiarism. Further, if someone derives an idea or a product from an already existing idea or product, but instead presents it a new idea, then also it is plagiarism. It is a serious ethical offense and sometimes considered as an act of fraud. Even if we take contents that are open for public use, we should cite the author or source to avoid plagiarism. (B) Copyright Infringement Copyright infringement is when we use other person’s work without obtaining their permission to use or we have not paid for it, if it is being sold. Suppose we download an image from the Internet and use it in our project. But if the owner of the copyright of the image does not permit its free usage, then using such an image even after giving reference of the image in our project is a violation of copyright. Just because it is on the Internet, does not mean that it is free for use. Hence, check the copyright status of writer’s work before using it to avoid plagiarism. (C) Trademark Infringement Trademark Infringement means unauthorised use of other’s trademark on products and services. An owner of a trademark may commence legal proceedings against someone who infringes its registered trademark. 11.4.3 Public Access and Open Source Software Copyright sometimes put restriction on the usage of the copyrighted works by anyone else. If others are allowed to use and built upon the existing work, it will encourage collaboration and would result in new innovations in the same direction. Licenses provide rules and guidelines for others to use the existing work. When authors share their copyrighted works with others under public license, it allows others to use and even modify the content. Open source licenses help others to contribute to existing work or project without seeking special individual permission to do so. Beware!! √ Plagiarism means using other’s work and not giving adequate citation for use. √ Copyright infringement means using another person’s work, without permission or without paying for it, if it is being sold. Activity 11.4 Explore the follouing websites to know about open/public licensing: (i) creativecommons.org for cc, and (ii) gnu.org for GNU GPL Ch 11.indd 237 21-May-19 12:45:19 PM 2020-21 238 Computer Science – Class xi The GNU General public license (GPL) and the Creative Commons (CC) are two popular categories of public licenses. CC is used for all kind of creative works like websites, music, film, literature, etc. CC enables the free distribution of an otherwise copyrighted work. It is used when an author wants to give people the right to share, use and build upon a work that they have created. GPL is primarily designed for providing public licence to a software. GNU GPL is another free software license, which provides end users the freedom to run, study, share and modify the software, besides getting regular updates. Users or companies who distribute GPL license works may charge a fee for copies or give them free of charge. This distinguishes the GPL license from freeware software licenses like Skype, Adobe Acrobat reader, etc. that allow copying for personal use but prohibit commercial distribution, or proprietary licenses where copying is prohibited by copyright law. Many of the proprietary software that we use are sold commercially and their program code (source code) are not shared or distributed. However, there are certain software available freely for anyone and their source code is also open for anyone to access, modify, correct and improve. Free and open source software (FOSS) has a large community of users and developers who are contributing continuously towards adding new features or improving the existing features. For example, Linux kernel-based operating systems like Ubuntu and Fedora come under FOSS. Some of the popular FOSS tools are office packages, like Libre Office, browser like Mozilla Firefox, etc. Software piracy is the unauthorised use or distribution of software. Those who purchase a license for a copy of the software do not have the rights to make additional copies without the permission of the copyright owner. It amounts to copyright infringement regardless of whether it is done for sale, for free distribution or for copier’s own use. One should avoid software piracy. Using a pirated software not only degrades the performance of a computer system, but also affects the software industry which in turn affects the economy of a country. Remember √ CC licenses are a set of copyright licenses that give the recipients, rights to copy, modify and redistribute the creative material, but giving the authors, the liberty to decide the conditions of licensing. √ GPL is the most widely used free software license which grants the recipients, rights to copy, modify and redistribute the software and that the same rights are preserved in all derivative works.

11.4 Data Protection
11.4 Data Protection In this digital age, data or information protection is mainly about the privacy of data stored digitally. Elements of data that can cause substantial harm, embarrassment, inconvenience and unfairness to an individual, if breached or compromised, is called sensitive data. Examples of sensitive data include biometric information, health information, financial information, or other personal documents, images or audios or videos. Privacy of sensitive data can be implemented by encryption, authentication, and other secure methods to ensure that such data is accessible only to the authorised user and is for a legitimate purpose. All over the world, each country has its own data protection policies (laws). These policies are legal documents that provide guidelines to the user on processing, storage and transmission of sensitive information. The motive behind implementation of these policies is to ensure that sensitive information is appropriately protected from modification or disclosure. 11.4.1 Intellectual Property Right (IPR) When someone owns a house or a motorcycle, we say that the person owns that property. Similarly, if someone comes out with a new idea, this original idea is that person’s intellectual property. Intellectual Property refers to the inventions, literary and artistic expressions, designs and symbols, names and logos. The ownership of such concepts lies with the creator, or the holder of the intellectual property. This enables the creator or copyright owner to earn recognition or financial benefit by using their creation or invention. Intellectual Property is legally protected through copyrights, patents, trademarks,etc. (A) Copyright Copyright grants legal rights to creators for their original works like writing, photograph, audio recordings, video, sculptures, architectural works, computer software, and other creative works like literary and artistic work. Why should we always mention the source from which we got an idea or used resources (text, image, audio, video, etc.) to prepare a project or a writeup? Think and Reflect Activity 11.3 Supose someone's email password is ‘tecnnology’ which is weak. Can you suggest a stronger password? Ch 11.indd 235 21-May-19 12:44:19 PM 2020-21 236 Computer Science – Class xi Copyrights are automatically granted to creators and authors. Copyright law gives the copyright holder a set of rights that they alone can avail legally. The rights include right to copy (reproduce) a work, right to create derivative works based upon it, right to distribute copies of the work to the public, and right to publicly display or perform the work. It prevents others from copying, using or selling the work. For example, writer Rudyard Kipling holds the copyright to his novel, ‘The Jungle Book’, which tells the story of Mowgli, the jungle boy. It would be an infringement of the writer’s copyright if someone used parts of the novel without permission. To use other’s copyrighted material, one needs to obtain a license from them. (B) Patent A patent is usually granted for inventions. Unlike copyright, the inventor needs to apply (file) for patenting the invention. When a patent is granted, the owner gets an exclusive right to prevent others from using, selling, or distributing the protected invention. Patent gives full control to the patentee to decide whether or how the invention can be used by others. Thus it encourages inventors to share their scientific or technological findings with others. A patent protects an invention for 20 years, after which it can be freely used. Recognition and/or financial benefit foster the right environment, and provide motivation for more creativity and innovation. (C) Trademark Trademark includes any visual symbol, word, name, design, slogan, label, etc., that distinguishes the brand or commercial enterprise, from other brands or commercial enterprises. For example, no company other than Nike can use the Nike brand to sell shoes or clothes. It also prevents others from using a confusingly similar mark, including words or phrases. For example, confusing brands like “Nikke” cannot be used. However, it may be possible to apply for the Nike trademark for unrelated goods like notebooks. 11.4.2 Violation of IPR Violation of intellectual property right may happen in one of the following ways: In this digital age, data or information protection is mainly about the privacy of data stored digitally. Elements of data that can cause substantial harm, embarrassment, inconvenience and unfairness to an individual, if breached or compromised, is called sensitive data. Examples of sensitive data include biometric information, health information, financial information, or other personal documents, images or audios or videos.

Why should we always mention the source from which we got an idea or used resources (text, image, audio, video, etc.) to prepare a project or a writeup?

Copyright law gives the copyright holder a set of rights that they alone can avail legally. The rights include right to copy (reproduce) a work, right to create derivative works based upon it, right to distribute copies of the work to the public, and right to publicly display or perform the work. It prevents others from copying, using or selling the work. For example, writer Rudyard Kipling holds the copyright to his novel, ‘The Jungle Book’, which tells the story of Mowgli, the jungle boy. It would be an infringement of the writer’s copyright if someone used parts of the novel without permission. To use other’s copyrighted material, one needs to obtain a license from them. (B) Patent A patent is usually granted for inventions. Unlike copyright, the inventor needs to apply (file) for patenting the invention. When a patent is granted, the owner gets an exclusive right to prevent others from using, selling, or distributing the protected invention. Patent gives full control to the patentee to decide whether or how the invention can be used by others. Thus it encourages inventors to share their scientific or technological findings with others. A patent protects an invention for 20 years, after which it can be freely used. Recognition and/or financial benefit foster the right environment, and provide motivation for more creativity and innovation. (C) Trademark Trademark includes any visual symbol, word, name, design, slogan, label, etc., that distinguishes the brand or commercial enterprise, from other brands or commercial enterprises. For example, no company other than Nike can use the Nike brand to sell shoes or clothes. It also prevents others from using a confusingly similar mark, including words or phrases. For example, confusing brands like “Nikke” cannot be used. However, it may be possible to apply for the Nike trademark for unrelated goods like notebooks. 11.4.2 Violation of IPR Violation of intellectual property right may happen in one of the following ways:
