The benefits of encryption
Encryption is useful for sending and storing private or sensitive information. For example, doctors and hospitals use encryption to keep your medical history confidential, while banks and online stores use encryption to keep your credit card details secure and reduce the risk of fraud.
Encryption also helps to protect your personal information when you browse the internet. Websites that have HTTPS at the start of their URL (online address) encrypt your data so that no one can spy on your online activity, like when you’re logging into accounts or filling out forms.
In addition, it’s useful for protecting communication with people who need to keep their identity hidden – for example, human rights activists or whistle-blowers who could be punished if they’re exposed. Defence forces and intelligence services also use it to make sure important communications are kept secret.
Newer laptops and mobile devices often have built-in encryption, providing an extra layer of security for the data stored on them if they are lost or stolen. Without a passcode or biometric ID such as a fingerprint or faceprint, it’s almost impossible to unlock the device and access the data.
