Description
Return distinct-person enrollment support.
Biometric research records separate subject IDs, template dimensions, image geometry, enrollment support and attempt budgets. Local counts and comparisons can reveal inconsistencies without reading biometric templates, detecting a physical trait or authenticating a person’s identity.
Return distinct-person enrollment support.
When to use this tool
Use Enrolled Sample Support Share when checking the stated biometric record, count, support, geometry or budget convention.
How to use the tool and how it works
- Enter personIds, sampleIds, qualityAccepted, enrollmentVerified. Follow any array-alignment requirements below. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read people, supportedPeople, distinctSupportedSamples, share, defined. Inspect defined before interpreting the associated values.
Return distinct-person enrollment support. Require aligned arrays; a nonempty sample with both qualityAccepted and enrollmentVerified supports its person, distinctSupportedSamples counts qualifying sample IDs globally, share divides supported people by all people or is undefined.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| personIds | Person Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| sampleIds | Sample Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| qualityAccepted | Quality Accepted | Required. Array of boolean; maximum items 256. |
| enrollmentVerified | Enrollment Verified | Required. Array of boolean; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| people | People | Required. Safe integer. |
| supportedPeople | Supported People | Required. Safe integer. |
| distinctSupportedSamples | Distinct qualifying sample IDs across all supplied people, not a sum of per-person sample counts. | Required. Safe integer. |
| share | Dimensionless numerator/denominator ratio under the explicit basis above. | Required. Finite number. |
| defined | Whether the stated denominator or information basis supports this value; inspect placeholders before interpretation. | Required. Boolean. |

}Limitations and assumptions
- Flags are supplied and one sample ID may occur for different people; no person/sample identity or enrollment quality is authenticated.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Use verified acquisition/enrollment records and the complete appropriate format and evaluation process for actual identity, quality, capacity or privacy decisions.
