Final answer:
Client-side encryption is the encryption of data on the client device, providing an extra layer of security for sensitive information during data transmission.
Step-by-step explanation:
In the context of data security, client-side encryption refers to the encryption of data on the client device.
When data is encrypted on the client device, it is protected by an encryption algorithm before it is transmitted to the server. This means that even if someone gains unauthorized access to the data on the server, they would not be able to understand or use the encrypted data without the decryption key.
This type of encryption provides an extra layer of security as it ensures that sensitive information remains encrypted and secure throughout the entire data transmission process.
