Data comes in different types. Some types need a significant amount of protection, and others do not.
For example, you don’t need to hide information about the weather forecast or the location of the local library. On the other hand, you don’t want the wrong people knowing your home address, ID number or debit card PIN.
Different types of data are considered private at an individual and institutional level. It’s impossible to list every data type you might want use encryption to protect, but here are the most common examples:
- Telephone numbers
- Bank and credit card details
- Health information
- Intellectual property, such as design for a proprietary device
- Financial Information
Governments also have sensitive data, such as military intelligence, that they need to protect with the highest levels of security.
