Originating in the United States, the Internet Sex Offender Registry was introduced into South Korea and given the special designation of a "security measure." However, both among the general public and certain scholars, the system is still perceived as a form of punishment or as a supplement to criminal sanctions. This is because, while the Registry outwardly takes the form of a security measure, it is substantively equivalent to a criminal punishment. The gap between appearance and substance can be traced to two main causes: first, the Registry does not conform to the conceptual requirements of a security measure, and second, it is rooted in past criminal punishments and in practice fulfills punitive purposes and functions. Currently, the system operates more as an additional punishment circumventing the principle of culpability than as a legitimate security measure aimed at special prevention.
Though the South Korean version of the Registry has developed under the name of a security measure, its content is not consistent with the concept. Unlike criminal punishment, a security measure should be based on the offender’s risk and imposed for the purpose of special prevention. Yet, the current Registry is disconnected from the recidivism risk of the individuals subject to disclosure and from the objective of special prevention. Rather, it functions as an additional harm imposed on the basis of the past offense. This is due not only to flaws in the enabling legislation but also to the internal logic of the Registry itself, which fails to maintain a rational connection with its purported preventive goals. Even if, for the sake of argument, we were to accept the Registry as a true security measure, it would still be difficult to escape the conclusion that it is unconstitutional.
In substance, the Internet Sex Offender Registry is closer to a criminal punishment. It takes the form of a public shaming mechanism, informing the general public of the offender’s past crimes—similar to traditional forms of penal humiliation. Historically prevalent across cultures, the punishment of public shaming briefly disappeared before reemerging in the U.S. as a condition of probation, shortly followed by the introduction of sex offender registries. Although the Registry has succeeded in shedding the formal label of “punishment,” it continues to impose widespread social disadvantages such as ostracization and exclusion. Due to its origins, features, and lack of preventive function, the Registry is now widely regarded by the public as similar to premodern punishment, and functions in practice as a punitive measure aimed at retribution and general deterrence.
As a security measure, the Registry’s limitations are clear. Most empirical studies have found no evidence that the system effectively reduces recidivism. The majority of the public does not even attempt to access the Registry, partly because the cost of obtaining the information is high while the perceived benefit is low. Factors contributing to this include the nature of sex crimes, the overwhelming number of individuals listed, the frequency of checks required, and the uncertainty of post-disclosure protection. Many individuals listed on the Registry perceive the public disclosure as unjust, and numerous criminological theories suggest that such perceptions undermine deterrence or even increase the likelihood of reoffending. A more serious issue is that these shortcomings are embedded in the core structure of the Registry itself—its reliance on voluntary access, its focus on sex crimes, and the indiscriminate nature of public disclosure—making legislative reform unlikely to yield meaningful improvement.
Numerous prior studies have argued for the need to supplement and improve the Registry, and have proposed specific measures to this end. However, these remedial measures appear unlikely to bring about significant changes in practice, nor do they seem capable of overcoming the inherent limitations of the system’s effectiveness. While certain proposals that presuppose the continued existence of the Registry may serve to mitigate some of its adverse effects, they ultimately fall short of fully resolving them. Redefining the purpose of the Registry as inducing voluntary self-restriction among offenders might address several conceptual inconsistencies, but it would in fact amount to institutionalized shaming. Such a move would risk socially excluding even those offenders with a high potential for reintegration and would further increase the likelihood of constitutional violations.
In light of these considerations, abolishing the Internet Sex Offender Registry appears to be the only viable solution to its structural and normative problems. Nearly 25 years after its introduction, the system still falls far short of qualifying as a "non-punitive and constitutional security measure." Given its inherent limitations, meaningful improvement seems unlikely. As long as the gap between the Registry’s outward form and its substantive function persists, this unconstitutional security measure should no longer be maintained. Concerns arising from the abolition of the Registry could be alleviated by introducing transitional measures or by replacing it with other effective security measure. The introduction of the Internet Sex Offender Registry was a misguided policy choice, and it is necessary to make the decision to abolish it in order to protect people’s fundamental rights.
