Question 38

Hashing provides assurance of data integrity.

Hashing is a one-way function that transforms input data into a fixed-size string of characters, which is typically a hash code. This process ensures that even the slightest change in the input data results in a completely different hash, thus providing assurance of data integrity.

A) Hashing

Hashing is indeed a one-way function that is designed to provide assurance of data integrity. It creates a unique hash value for a given input, allowing for the detection of any alterations to the original data. If the data is modified, the hash will change, indicating that the integrity of the data has been compromised.

B) Sailing

Sailing is not applicable in this context as it refers to the act of navigating watercraft. It does not relate to data integrity or any form of data processing, making it an incorrect choice for this question.

C) Segmentation

Segmentation refers to the division of data or networks into smaller parts for better management and efficiency. While it plays a role in data handling, it does not function as a one-way method for ensuring data integrity, thus making it an incorrect option.

D) Tokenization

Tokenization is the process of replacing sensitive data with non-sensitive equivalents, or tokens, that can be used in a transaction without exposing the original data. While it enhances security, it does not serve as a one-way function for confirming data integrity, rendering this option incorrect.

Conclusion

Hashing is the only option that effectively serves as a one-way function for ensuring data integrity, as it provides distinct hash values that change with any data alteration. The other options either do not pertain to data integrity or lack the one-way functionality necessary for this purpose. Therefore, hashing is the definitive choice for this question.
