Explanation:
The Internet has made our lives easier in many ways. We now shop online, keep in touch with friends, pay bills, market our businesses and keep up with current affairs in cyberspace.
The Internet is also incredibly useful for finding information that would have required a trip to the local library 30 years ago. Need to check out the 12th game of the 1927 world chess championship or find the best hotel in Santa Cruz, Bolivia? Want a quick recipe for pumpkin soup or a tutorial on video editing? You can get all this and more in a matter of minutes online.
Criminals are also excited about this wealth of information, because it gives them access to personal details that can be used for unlawful activities. Staying safe online is mostly about being alert to the dangers.
Here are some useful tips for increasing your Internet safety:
Don’t become a victim of identity theft
Thieves only need to collect a few pieces of information before they have enough to steal your identity.
Identity theft is a serious issue in Australia. Criminals increasingly turn to the Internet for easy pickings. In 1 out of 5 instances, your stolen identification details are used to gain credit or apply for a loan. Around a third of Australian identity theft victims don’t even realise anything has happened until they receive an official notification or query from a government agency.1
Although people often use the terms interchangeably, there are distinct differences between identity theft and identity fraud. Identity theft occurs when a thief accesses your personal information in order to impersonate you (in person or online), mainly to open accounts in your name. They might even use your details to take control of your existing accounts.
Identity fraud is a little different: instead of stealing your identity, the thief uses your details to create a fictitious person in order to defraud merchants. Both identity theft and identity fraud are sinister crimes that affect all Australians, because merchants, credit card issuers, utility companies and other entities must factor these crimes into their pricing structure, resulting in higher costs for everyone.
