Which of the following are possible IDC determinations?

The correct answer identifies the possible IDC (Identity Data Classification) determinations as consisting of a no match, a low threshold match, and a high threshold match. This classification system allows for varying degrees of similarity between data entries, accommodating different contexts and nuances in comparing identities.

A "no match" determination indicates that the data does not correspond to any existing records, which is essential for understanding unique entries. A "low threshold match" suggests that there is some similarity but not enough to confirm identity definitively—the records may be similar but could pertain to different individuals or entities. A "high threshold match," on the other hand, indicates a very strong likelihood that the records refer to the same identity based on the criteria used for comparison.

By using a tiered approach to matching, this system provides greater flexibility and accuracy in data assessment, which is especially useful in complex datasets where nuances matter. It enables practitioners to handle various scenarios in identity matching, ensuring better data integrity and reducing errors in identification processes.
