data encryption

Data encryption protects sensitive information on a computer.

Definition
  1. Noun:
    • (Computer Science) The encryption of data for security purposes: "Data encryption" refers to the process of converting plain, readable information (data) into an encoded, unreadable format. This is done to protect the data's confidentiality and integrity, especially during storage or transmission over networks. Only authorized parties with the correct decryption key can convert the encrypted data back to its original, usable form.
Usage Examples
  • Noun:
    • Modern messaging apps use end-to-end data encryption to protect your private conversations.
    • The company implemented strong data encryption for all customer records stored in its database.
    • Without proper data encryption, sensitive financial information sent online is vulnerable to theft.
Advanced Usage

  • "At-rest data encryption": The encryption of data while it is stored on a device or server.

    • The new policy requires at-rest data encryption for all files on company laptops.

  • "In-transit data encryption": The encryption of data while it is being transmitted from one location to another.

    • The website uses SSL/TLS for in-transit data encryption to secure your login details.
