Protecting personal information

12 Sep 2018

Personal information is anything that can be used to identify you in real life.

Chances are, you do not leave your money lying around your classroom. Your personal information is the same: it is the currency that criminals use to commit several types of scams. With your personal information, they may be able to access your social media accounts to make posts under your name, or even your bank account (the one your parents likely set up for you) to steal your money – things that may seriously hurt you!

Singapore recently experienced the SingHealth cyber-attack, where 1.5 million SingHealth patients had their data breached, gaining information such as their personal particulars and medication data. This caused public outcry as people realised the potential risks involved in such a breach, and SingHealth was quick to reach out to affected patients and provide them the necessary information to take steps moving forward. Although the SingHealth data breach was not the work of casual hackers or criminals, it acts as a timely reminder for Singaporeans to better understand the importance of protecting their personal information in their everyday lives as well.

What are examples of personal information?

  • Full name
  • Address
  • Phone number
  • Photos
  • Date of birth
  • NRIC number
  • School
  • Email address
  • Passwords

When might I share personal information?

There are several activities online which require some disclosure of your personal information, including:

  • Registering: signing up for sites often requires a name and email address, but you may sometimes be asked for your gender, date of birth, and more, but a red asterisk (*) often marks out the fields you must enter to register
  • Shopping: sites may ask for further details to verify your identity, process payments, and make deliveries
  • Contests: these often require you to share extensive personal information, including your interests, which are then used by sellers to promote their goods or services

What happens if someone has my personal information?

There are many possible consequences of sharing personal information, including:

  • Spam emails
  • Scams
  • Fraud
  • Identity theft
  • Damage to reputation

How can I protect my personal information?

  • Only use secure websites when sharing personal, and especially financial, information: look at the URL bar and check that it begins with https:// and has a ‘locked’ padlock symbol on the left, which indicates that your data is encrypted
  • Make sure that the websites are authentic by checking the URL address: there are many fake government websites trying to get your NRIC or passport number, and fake banking websites trying to get your financial information
  • Read user agreements and privacy policies: try not to give your email address to organisations that sell your information so as to prevent spam emails from flooding your inbox
  • Check your social media account settings: make sure that your social media is set to private wherever possible, so that only people you know can see your content
  • Check your device settings: every smartphone and tablet has privacy settings, so disable functions like location services, sharing of contacts or photos, or Bluetooth sharing
  • Never share your password with anyone
  • Use a different password for each online account, and change them regularly
  • Set strong passwords, which are more than 8 characters long, and include numbers, symbols, and both lowercase and uppercase letters. Here is how you can create a strong password:
    • Think of a sentence with at least 8 words (Jack and Jill went up the hill)
    • Take the first letter of each word (jajwuth)
    • Change some letters to uppercase (JajwUth)
    • Change some letters to symbols (J&jwUth
    • Add some numbers (J&jwUth2)

Someone has used my information. What can I do?

  • If someone has stolen your password, change it on all affected platforms immediately
  • If you are constantly receiving spam emails, try to block the senders of the emails or unsubscribe to the mailing list, but if the problem persists, you may have to create a new email address
  • If someone has used your personal information to harm you – such as by stealing your identity, or threatening to visit and harm you or your family – contact the authorities at 999
