Face recognition at a Chiayi jail works within 3 seconds in a test

Taiwan's Control Yuan tested face recognition at the Chiayi Detention Center on 29 September 2021. It found that recognition finished within 3 seconds with a very high recognition rate.

  • 1 an organization

    The Control Yuan found in its test that recognition finishes within 3 seconds, a time saving for staff that it did not measure.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Status
Reported benefit.
Evidence

An independent audit report supports the benefit.

Compared with

Face recognition as described in a December 2020 press report, which the Minister of Justice said referred to the old 2016 project. Assumed without a measurement.

The system’s part
Not isolated. The Control Yuan timed the face recognition in a site test and judged its recognition rate very high. It gave no measured rate and did not compare identification with and without the system. It does not describe how the face recognition was built or trained.

Details

AI system

Workflow

The Chiayi Detention Center installed the smart prison systems in 2020 with judicial-technology funds from the Ministry of Science and Technology. The face recognition was one module of a smart surveillance system, beside a module for behavior analysis.

Follow-up

Conditions for replication

Inmates must face the camera when the system checks a group at the central control desk. Camera angle and resolution, which depend on the budget, must support recognition.

Entry details

Sector

Prisons.

Purpose

A vendor that the Control Yuan does not name built the face recognition for the Agency of Corrections' smart prisons, to identify inmates and offset staff shortages.
