Electronic monitoring System
Currently, the business of using technological equipment to implement surveillance at the Taiwan High Prosecutor's Office includes the Technology Device Monitoring for Sexual Assault Offenders (TDMSAO) and the Technology Device Surveillance for Defendants during Suspension of Detention (TDSD).

Technology Device Monitoring for Sexual Assault Offenders (TDMSAO)
The business of TDMSAO in Taiwan, since targeting sexual assault parolee divert to protective control measures during parole period in 2006. According to the Ministry of Justice promulgated "The Regulation For The Implementation Of Technological Equipment Monitoring For Sexual Assault Offenders Diverted Protective Control Measures” . We began to undertake this business, then handled the matters about purchase and maintenance for technology monitoring equipment in 2008.

In order to respond to changes in Taiwan’s communications environment policies and strengthen the front-end of monitoring equipment. We are gradually improving equipment functions, data analysis functions, portable transmitter structure, and strengthening information system security. In addition, we have also developed a monitor user interface and an APP for overall maintenance operations about equipment of TDMSAO.

TDMSAO in accordance with legal provisions from early, the fixed-point, fixed-time "curfew supplemented by technological equipment monitoring" transformed to the current "satellite positioning full-time monitoring." And based on the crime pattern and living conditions of the individual cases, restricted areas and prohibited outing periods are defined. Moreover, we use technological monitoring methods, coupled with regular follow-up counseling by the probation officer, to help cases improve their self-management and psychological internal control capabilities and to enhance the effectiveness of preventing recidivism.

Technology Device Surveillance for Defendants (TDSD)

In order to prevent defendants who are without detention or whose detention has been suspended from escaping during an investigation or trial. The Criminal Procedure Law updated the mechanism of ‟Technology Equipment Monitoring and Anti-Escape” on July 17, 2019. Article 116-2(1)(d): ‟ When the court permits the suspension of detention, after considering the protection of human rights and the balanced maintenance of public interests, if deemed necessary, the court may specify a certain period of time, then ruling an order, that is to say, the defendant shall comply with the following matters: ...... (d) Accept appropriate technological equipment monitoring. ”

Later, the Judicial Yuan and the Ministry of Justice reached a consensus and entrusted the Taiwan High Prosecutor's Office to plan and build the Electronic Monitoring Center (EMC).

Based on this, the department has established a technology monitoring team, and the "Technology Equipment Monitoring Center" has been completed on the 2nd floor of the old building of the Taiwan Shilin District Prosecutor's Office in November 2021. We began to use technological equipment to replace traditional supervision manpower, consider the defendant's criminal circumstances and basic human rights, and plan vehicles with different functions and effects. For example, case mobile phones, electronic hand bracelets, electronic foot bracelets, home readers, etc., using positioning technology paired with geographical maps and supplemented by electronic fences, prompt the supervisor to master the defendant's whereabouts 24 hours a day through the monitoring system platform and mobile app.

Future outlook
Technology Equipment Monitoring Center plan to reorganize the TDMSAO and the Prisoner Escape Prevention Monitoring System for Furlough of External Penitentiary and
