Security is about keep data safe from users who should not have access to that information (unauthorized users). This data can be read, used or corrupted, so the idea of data security was born. Data security helps people keep their files confidential and keep it protected. Data security’s purpose is to keep data from being used by unauthorized users. A form of data security is encryption, encryption works but scrambling letters and numbers into an unreadable code. Only the authorized users will have the key to unscramble the code and get the correct data. Data protection and security allows users to identify and view the issues and risk that are known when retrieving the data which can be deleted or lost through not only hackers and viruses and natural disasters.

The loyalty card shows the details of customer which were given when signing up for the card so the products bought are linked to the customer. While internet based companies like http://www.pcspecialist.co.uk/ live out free credit and discounts when you return and login to your customer account.
