Description
Return one subject's distinct gallery templates and duplicate positions.
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 one subject's distinct gallery templates and duplicate positions.
When to use this tool
Use Biometric Gallery One Subject Multiplicity when checking the stated biometric record, count, support, geometry or budget convention.
How to use the tool and how it works
- Enter subjectIds, templateIds, targetSubject. 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 templateIds, distinctTemplates, duplicateTemplateIndices. Use the output convention below.
Return one subject's distinct gallery templates and duplicate positions. Require aligned subject/template arrays; filter targetSubject, preserve first-seen template IDs and report original indexes of later repeats for that subject.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| subjectIds | Subject Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |

| targetSubject | Target Subject | Required. Text; maximum UTF-16 length 8192. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| templateIds | Template Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| distinctTemplates | Distinct Templates | Required. Safe integer. |

}Limitations and assumptions
- Template identifiers are literal records; no template contents, person identity or actual gallery search is inspected.
- 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.
