Ways of representing data
Infographics
- A visual representation of information that combines text, images, and charts to convey complex data clearly.
- Infographics are used to simplify complex information and make it engaging.
Data Visualization
- The process of converting data into visual representations like charts, graphs, and infographics.
- Visualizations are used to make data easier to understand and interpret.
Data visualization helps to communicate information effectively and make data-driven decisions.
Theory of KnowledgeHow does the way data is represented affect our understanding and interpretation of it?
Data Security
- The protection of data from unauthorized access, use, disclosure, disruption, modification, or destruction.
- Data security is crucial to ensure that data is protected and not misused. There are several techniques to ensure data security:
- Encryption
- Data masking
- Blockchain
Encryption
- The process of converting readable data into unreadable characters to prevent unauthorized access.
- Encryption is a process that transforms plain text into cipher text using an encryption key.
- The encryption key is a string of characters that is used to encrypt the data.
- The cipher text is the encrypted data that is unreadable without the encryption key.
- The cipher text can be decrypted back into plain text using a decryption key.
- The decryption key is a string of characters that is used to decrypt the data.
- The decryption key can be the same as the encryption key (which is known as symmetric encryption) or different to the encryption key (asymmetric (public key) encryption).
- Asymmetric key encryption is much more secure than symmetric encryption due to the usage of two separate cipher keys.
- However, due to this same reason, it is also more difficult to implement and requires additional safety protocols.
