The advent of intelligent technologies, notably Brain–Computer Interfaces (BCIs), has introduced novel privacy dilemmas. Ensuring judicious privacy transfer is imperative for the application of BCI technology and pivotal for fostering economic and technological progress. This study adopts privacy transfer as the research perspective and employs an ethical matrix as the research method. It establishes BCI users as the central core interests, with marketers, developers, and medical personnel as stakeholders. Departing from the binary opposition of public and private in traditional privacy theory, this article proposes ethical principles such as maximizing benefits, minimizing harm, and respecting independent decision-making power. It constructs a judgment matrix for the privacy transfer of BCIs, utilizing this matrix to identify ethical risks like privacy disclosure and hijacking. This study analyzes the reasons for risks, aiming to overcome dilemmas and construct an ethical matrix to explore privacy transfer boundary division methods suitable for BCI technology and tailored to different stakeholders.

脑机接口隐私转移困境的视角与边界探索——基于伦理矩阵的维度

智能技术的出现，特别是脑机接口（BCI），带来了新的隐私困境。确保明智的隐私转移对于 BCI 技术的应用至关重要，也是促进经济和技术进步的关键。本研究以隐私转移为研究视角，采用伦理矩阵为研究方法。它将BCI用户建立为核心利益中心，营销人员、开发人员和医务人员为利益相关者。本文摆脱传统隐私理论中公与私的二元对立，提出利益最大化、损害最小化、尊重独立决策权等伦理原则。构建了脑机接口隐私转移的判断矩阵，利用该矩阵识别隐私泄露、劫持等伦理风险。本研究分析风险产生的原因，旨在克服困境，构建伦理矩阵，探索适合BCI技术、针对不同利益相关者量身定制的隐私转移边界划分方法。
