為有效預先防範風險轉變為危害，必須立法授權警察機關得採取許多蒐集資料的措施，這些干預措施會侵害人民的基本權利。在我國警察法危害防止領域內，如何立法因應，避免以追求提升行政效率或保障國家安全為名，發動對人民廣泛性的監控，過度侵害人民的自由權利，深具研究價值。本文以警察法領域為研究範圍，全文計分為五部分，除前言外，分別討論透過資訊科技進入電腦蒐集資料的憲法問題、德國聯邦憲法法院的相關判決與法制、以及我國警察法上的法律依據，最後提出結論與建議。
In order to effectively prevent risks from turning into hazards, it is necessary for the legislation to authorize the police to take measures to collect information. However, these measures may violate the human rights. In police law, how to legislate so that the monitoring is not excessive and human rights are not infringed, in the name of improving efficiency or safeguarding national security, has profound research value. Within the scope of police law, this article is divided into five parts. In addition to the preface, it discusses the constitutional issues of secret infiltration of computers to collect informations, the relevant judgment of the German Federal Constitutional Court and legal systems, the legal basics of police law in my country, and at last, states conclusions and recommendations.
