What is the function of fixity information?

Fixity information plays a crucial role in digital preservation by providing assurance that a digital object remains unchanged over time. This involves verifying the integrity of a file or collection of files by using methods such as checksums or hash values. When fixity information is established, it allows archivists and digital curators to monitor the condition of digital objects, ensuring they have not been altered, lost, or corrupted unintentionally.

This is particularly important in the context of long-term digital preservation, where the risk of data degradation or modification is a significant concern. By maintaining and regularly checking this fixity information, organizations can act quickly if discrepancies are found, thus safeguarding the authenticity and reliability of their digital assets.

The other options relate to improvements in quality, user access, and data transfer efficiency, which are not the primary focus of fixity information.
