Understanding Data Encryption
What is Data Encryption?
In this video, we will explore the concept of data encryption and its role in protecting information from fraud. Most of the time, you may not be aware that your data is being encrypted, but this process is crucial for data security.
How Does Data Encryption Work?
Data encryption is a security measure that encodes information so that it can only be accessed or decrypted by users with the correct encryption key. Encrypted data, also known as ciphertext, appears scrambled or unreadable to unauthorised individuals or entities.
Encryption is a mathematical function that protects information stored on both mobile and static devices, as well as data in transmission. Various encryption options are available to suit different security needs.
Legal Requirements for Data Encryption
Companies are legally required to encrypt data to ensure its security. The General Data Protection Regulations (GDPR) mandate that personal data must be held securely, and encryption is one of the recommended methods to achieve this. Companies can implement encryption measures easily and cost-effectively.
Everyday Examples of Data Encryption
Often, your data is encrypted without you even realising it. Here are some common examples:
- Server Storage: Data stored on computer servers must be secure and readable only by authorised users. Encryption ensures that no unauthorised person can access this data without the correct key.
- Data Transmission: Data is encrypted when transmitted between two sources, such as your computer and a website. For example, when you access your bank online, the data you send is encrypted to prevent interception by unauthorised parties.
The Importance of Data Encryption
Encryption is vital for protecting sensitive information from fraud and unauthorised access. Whether the data is stored on a device or transmitted over the internet, encryption ensures that it remains secure and only accessible to authorised users.
Conclusion
Data encryption is an essential security measure that protects information from fraud and unauthorised access. By encoding data in such a way that only authorised users can access it, encryption plays a crucial role in safeguarding personal and sensitive information, ensuring compliance with legal regulations like GDPR.
