社會關係網絡視角下個人信息的私密與公開

個人信息的私密與公開之判斷，是個人信息保護的前提性、基礎性與根本性問題。然而，當前判定私密信息的各種理論皆有不足：微觀的場景理論之實質性與體系性有缺失，中觀的要件理論之操作性待提高，而宏觀的功能理論對私密信息欠保護。私密信息判定的社會關係網絡理論將社會科學融入法學教義，能夠對此問題予以更佳回應：只需將網絡結構與信息性質、技術架構結合，即可確定信息經由何種關係傳播到網絡的哪個節點與位置時，最有可能繼續廣泛傳播，不再私密；這亦適用於一般個人信息的保護與利用。智能時代的數字技術一方面提高了社會關係網絡的傳播效率，模糊了公私界限，助力信息傳播；另一方面也致使信息過載、信息失真、信息繭房等問題愈演愈烈，造成結構洞新增與固化，阻礙信息傳播，最終導致個人信息的私密與公開問題陷入新的不確定性。

The determination of whether personal information is private or subject to disclosure constitutes a preliminary, foundational, and fundamental issue in personal information protection. However, existing theories for identifying private information each suffer from certain deficiencies: at the micro level, the contextual integrity theory lacks substantive depth and systematic coherence; at the meso level, the element-based approach requires greater operational feasibility; and at the macro level, the functional theory provides insufficient protection for private information. The social network theory for determining private information integrates insights from the social sciences into legal doctrine and offers a more effective response to this problem: by combining network structure with the nature of information and technological architecture, it becomes possible to identify the point at which information, once transmitted through particular relationships to specific nodes and positions within a network, is highly likely to continue spreading widely and thus cease to remain private; this framework may even be applied to the protection and utilization of personal information more generally. In the age of intelligent technologies, digital technologies have not only further enhanced the transmission efficiency of social networks, blurred the boundary between the public and the private, and facilitated information dissemination, but have also intensified such problems as information overload, information distortion, and information cocoons, promoted the emergence and consolidation of structural holes, hindered the circulation of information, and ultimately introduced new uncertainties into the determination of whether personal information should be regarded as private or public.
