Date of birth precision detailed examples

The following examples represent the data as it is compared along with the resulting date of birth precision scores. The first date of birth represents the existing date of birth for an entity in the entity database, and the second date of birth is for an incoming date of birth identity.

Precision level: Exact (100 point)

This case shows two exact dates. The algorithm will generate a 100 point match.

DATE OF BIRTH STATUS
1963/12/01 Existing
1963/12/01 Incoming

Precision level: Tight (90 point)

This case shows two dates whose precision score is greater than or equal to 90 points. The example shows two date of birth values with the same year and day value, but the month value is different by one month.

DATE OF BIRTH STATUS
1963/12/01 Existing
1963/11/01 Incoming

Precision level: Medium (85 point)

This case shows two dates whose precision score is greater than or equal to 85 points. The example shows two date of birth values with the same month and day value, but the last two digits of the year value are transposed.

DATE OF BIRTH STATUS
1963/12/01 Existing
1936/12/01 Incoming

Precision level: Loose (80 point)

This case shows two dates whose precision score is greater than or equal to 80 points. The example shows two date of birth values with the same month and day value, and the third digit of the year value incorrect (which still is a rational value for a date of birth).

DATE OF BIRTH STATUS
1963/12/01 Existing
1933/12/01 Incoming
