電腦科技之於資訊時代，正如機械化之於工業革命，資訊工業逐漸成為本世紀末及下世紀時代之主流，其將主宰一切人類活動，「資訊即權力」之社會型態於焉形成；「水能載舟，亦能覆舟」，資訊革命固然積極的拓展人類生活空間，改變生活型態，但卻也隱藏著令人擔憂之問題-電腦犯罪以及人權之侵害等，有關後者各先進國家紛紛制定「個人資料保護法」以為保護與防範。在該等法制規範之內容中，除規定公務機關與非公務機關蒐集、處理與利用個人資料之要件與程序外，資料當事人於其資料遭上述機關蒐集、處理與利用時所擁有之權利，亦是規範之主軸，限於篇幅，本文僅就後者予以論述。論文中首先就「當事人權利」之概念，詳細加以剖析；然後針對當事人權利之保障與限制在我國「電腦處理個人資料保護法」中規範之情形，予以探討；同時並與德國法制做比較法上之觀察，藉由德國法上之經驗與見解指出我國該法之正確解釋方向與不足的地方；最後再就「當事人權益之保障」與「促進個人資料之合理利用」之目的略做說明，以為結語。
