Preeti should use the concept named encryption. Encryption is the method by which information is converted into secret code that hides the information’s true meaning.

Answer:
Encryption is the process of converting a readable message into an unreadable form, also known as ciphertext, using a cryptographic algorithm. It is a technique used to ensure the confidentiality of data being transmitted over a network or stored on a device. In this case, Preeti is using encryption to protect the confidentiality of her message.
Encryption Process:
1. Readable Message: Preeti starts with a readable message that she wants to send to her colleague.
2. Encryption Algorithm: She uses an encryption algorithm, such as Advanced Encryption Standard (AES) or RSA, to convert the message into ciphertext.
3. Ciphertext: The encryption algorithm transforms the readable message into an unreadable form, which is known as ciphertext. This ciphertext can only be decrypted back into the original message using a decryption key.
Benefits of Encryption:
- Data Confidentiality: Encryption ensures that only authorized recipients can access and understand the message. It protects sensitive information from unauthorized access.
- Data Integrity: Encryption can also provide data integrity by detecting any unauthorized modifications or tampering with the encrypted message. If any changes are made to the ciphertext, the decryption process will fail, indicating that the message has been compromised.
- Secure Communication: By using encryption over a secure channel, Preeti can securely send confidential information without the fear of interception or eavesdropping by attackers.
Other Options:
- Decryption: Decryption is the reverse process of encryption. It involves converting the unreadable ciphertext back into the original readable message using a decryption key. While decryption is essential for the intended recipient to read the message, the question specifically asks for the technique to convert a readable message into an unreadable message, which is encryption.
- Plagiarism: Plagiarism refers to the act of copying someone else's work or ideas without giving proper credit. It is unrelated to the concept of encryption.
- Data Security: Data security is a broader term that encompasses various techniques and measures, including encryption, to protect data from unauthorized access, modification, or destruction. While encryption is a crucial aspect of data security, it is only one component of a comprehensive data security strategy.
