The 20 questions

  1. What is a digital footprint?

    • The size of the hard drive that a person uses to store their files on a laptop
    • The number of steps a person walks each day while carrying a mobile device with them
    • The trail of data a person leaves through their online activity, posts and accounts
    • The list of websites that a search engine has blocked for a particular region

  2. Why should a pupil think carefully before sharing personal information online?

    • Information shared online is deleted automatically after a day, so there is little risk
    • Information shared online can never be found by search engines, so it is always private
    • Information shared online is only visible to the pupil's own family and close friends
    • Information shared online can be copied, kept for years and seen by people the pupil does not know

  3. Which of these is personal information that should be kept private?

    • The colour of the classroom walls, which can be seen by anyone who visits the school
    • The full home address and date of birth of the pupil
    • The name of a famous football club that the pupil supports as a fan in a public way
    • The name of a favourite film that has been widely reviewed in the national newspapers

  4. What does a privacy setting on a social media account usually control?

    • The colour and design of the profile picture that appears on the account screen
    • Who can see the user's posts, profile details and contact information
    • The number of languages in which the account can be used by the user each day
    • How fast the account loads on a device that has a slow internet connection at home

  5. Why might a pupil turn off location sharing on a photo app?

    • Photos can contain location data that reveals where the pupil lives or spends time
    • Location sharing makes photos blurry, so the photos look worse when they are shared
    • Location sharing stops the photo app from working on a tablet with no internet connection
    • Location sharing makes the photo file much larger, which uses up storage on the device

  6. Why should a pupil use a different password for each important account?

    • Different passwords mean that the accounts never need to be updated by the provider
    • Different passwords make the accounts load faster, because each has its own cache
    • If one password is leaked, the other accounts stay protected from being accessed
    • Different passwords make it unnecessary to log out of the accounts on a shared device

  7. Which statement about a public social media profile is correct?

    • Anyone on the internet may be able to see its content, including people the user does not know
    • Public profiles are automatically deleted after a week, so their content does not last
    • Only the people the user has approved as friends can ever view the content in any case
    • Public profiles cannot be searched for or found by people who are not already contacts

  8. What is an online identity?

    • The login password a person sets to access one account on a school network, kept private to them alone
    • A serial number built into a device to identify it on a local area network, such as the MAC address of its network card
    • A type of virus that copies a person's photos and personal details from their device and sends them on to a stranger online
    • The way a person is represented online, through their accounts, profile and the information they share

  9. Why should a pupil check the age rating and terms of an app before signing up?

    • To find out whether the app's icon has the most attractive colours on the device
    • To confirm that the app can be used without any internet connection at all times
    • To check how many other apps the developer has built and released in the last year
    • To make sure the app is suitable for their age and to know how their data will be used

  10. What is a cookie in a web browser?

    • A small file a website stores on the device to remember settings or track visits
    • A type of sweet that is sold in school shops to pupils at break time each day
    • A program that deletes every file on a device once the user has visited a website
    • A password that is stored in the browser so that it can be shared with a friend

  11. Why might a pupil want to review the apps that have access to their contacts or camera?

    • Access to contacts or camera makes the apps load more slowly on the device each day
    • Access to contacts or camera only affects the colour of the icons on the home screen
    • Access to contacts or camera is required by law, so it cannot be changed by the user
    • Access to contacts or camera can expose personal information if the app is misused

  12. Which of these is a sensible way to protect online identity?

    • Use a username that does not reveal your full name, age or school
    • Use your full name, age and school name as the username so that friends can find you
    • Share your password with trusted friends so that they can help to manage your account
    • Post your school timetable on your profile so that people know when you are online

  13. What is the main risk of a 'friend' accepted from someone the pupil has never met in person?

    • The person may not be who they claim to be and may gain access to private information
    • The friend will always be an adult, which means the pupil will learn a new skill quickly
    • The friend's account will automatically delete the pupil's profile after one week
    • The friend will reduce the pupil's storage space, which slows down the device they use

  14. Why are personal data rights important?

    • They make it compulsory for every person to share their full address with every website
    • They remove the need for any privacy settings, because the law controls all data use
    • They make all personal information public so that everyone can see it in the same way
    • They give people control over how their personal information is collected, used and kept

  15. What should a pupil do if an app asks for more personal data than it seems to need?

    • Provide all the requested data quickly, because the app must need it to work properly
    • Provide the data but use a false name, so that the app cannot connect the data to them
    • Question the request, check the privacy settings and choose not to share unnecessary information
    • Delete the app at once and then reinstall it, so the request appears again for the same data

  16. Which statement about privacy online is correct?

    • Privacy only matters for adults, because children have nothing that needs protecting online
    • Privacy is fixed by the internet company, so the user has no say in how data is shared
    • Privacy is guaranteed once an account has a password, so no further action is needed
    • Privacy depends on settings, habits and what people choose to share, so it needs ongoing attention

  17. What is the best reason to review old posts on a social media account?

    • Old posts must be kept forever by law, so they should not be removed under any circumstances
    • Old posts are automatically sent to the school each term for the teacher to check
    • Old posts may reveal personal information or content that the pupil no longer wants to share
    • Old posts make the account load more slowly, so they should be removed to speed it up

  18. Which information is a sensible thing to share publicly online?

    • A photo that shows the house number and street name of the pupil's own home
    • The times each day when the pupil is alone at home, so friends can visit then
    • The name of the school, the year group and the usual route home from lessons
    • A general interest in a hobby, such as painting, without any personal details

  19. What does 'public by default' mean for an online account?

    • Only the account owner can see the content, because public accounts are always locked
    • The account is shown to the owner's school only, and never to other people online
    • The account is deleted automatically every time it is made public by the account owner
    • Anyone can see the account's content unless the user changes the privacy settings

  20. Why might old public content about a person still appear in search results?

    • Content that was public may remain indexed or copied until it is removed at source
    • Search engines show only content that is less than one day old in their search results
    • Search engines only show content that the user has approved in their privacy settings
    • Search engines keep every post for ever, even after the user has deleted it from the site
