What term describes the process of encoding data so that only authorized users can access it?

The term that describes the process of encoding data so that only authorized users can access it is encryption. This method involves transforming readable data into a coded format using an algorithm and a key, so that it can only be read or decrypted back into its original form by those who possess the appropriate key. This ensures confidentiality and security, making the data inaccessible to unauthorized users.

Encryption is widely used in various applications, such as securing communications, protecting sensitive information in databases, and ensuring the integrity of files. It plays a crucial role in safeguarding data, especially in an era where data breaches and cyber threats are prevalent.

In contrast, encoding refers to converting data into a different format for storage or transmission purposes but does not secure it against unauthorized access. Hashing is a process that takes an input and generates a fixed-size string of characters, which is typically used for verifying data integrity rather than securing it against unauthorized access. Decryption is the reverse process of encryption, transforming the encrypted data back into its original format, but it is not the term that describes the encoding process itself.
