Which of the following is NOT considered a basic method to maintain data integrity?

Data integrity refers to the accuracy and consistency of data over its lifecycle, and maintaining it is crucial for ensuring that information remains unaltered and trustworthy. Hashing, regular audits, and digital signatures are all established methods used to uphold data integrity.

Hashing transforms data into a fixed-size string of characters, generated by a specific algorithm. This unique representation helps verify that the original data has not been altered; any change in the data would result in a different hash value, indicating a potential integrity issue.

Regular audits involve systematic reviews of data and processes to ensure compliance with policies and standards. They help identify discrepancies, unauthorized changes, or irregularities in data, thereby reinforcing its integrity.

Digital signatures provide a means to confirm the authenticity and integrity of digital messages or documents. By using cryptographic techniques, a digital signature ensures that the content was created by a specific individual and has not been altered after signing.

In contrast, data breaches refer to unauthorized accesses or exposures of data, which compromise its integrity rather than maintain it. Thus, data breaches are contrary to the principles of data integrity and represent failure rather than a method of safeguarding data accuracy and consistency.
