The U.S. Department of Homeland Security has recently proposed a new rule that would require travelers from Visa Waiver Program countries—such as those in the Schengen Area, the United Kingdom, Japan, and South Korea—to disclose all social media accounts they have used over the past five years when applying for ESTA (Electronic System for Travel Authorization). The measure aims to enhance border security screening by analyzing travelers’ online activity to identify potential security threats.Under the proposal, applicants would need to voluntarily provide usernames, platform names, and usage periods for their social media accounts, though private messages and passwords would not be requested. While officials stress that the policy is not targeted at any specific country or group and that collected data will be subject to privacy protection laws, it has sparked widespread concerns over privacy rights, freedom of expression, and potential data misuse.Critics argue that mandatory disclosure of social media history could create a chilling effect on international travel, particularly affecting journalists, academics, and political dissidents. Questions also remain about how such vast amounts of data will be securely stored and ethically used. The proposal is currently in a public comment period and has not yet been finalized. If implemented, it could impact tens of millions of visa-free travelers annually.Supporters contend that expanding digital background checks is a necessary step amid rising risks of terrorism and transnational crime. However, striking the right balance between national security and civil liberties remains a central challenge for policymakers.
近日，美国国土安全部提出一项新提案，拟要求来自免签证国家（如申根区、英国、日本、韩国等）的游客在申请ESTA（电子旅行授权系统）时，提供过去五年内使用过的所有社交媒体账号信息。该措施旨在加强边境安全审查，通过分析旅客的在线活动，识别潜在的安全威胁。根据提案内容，申请人需主动申报包括用户名、平台名称及使用时间段在内的社媒账户信息，但不包括私密聊天记录或密码。尽管官方强调此举并非针对特定国家或群体，且数据将受到隐私保护法规约束，但仍引发了关于隐私权、言论自由和数据滥用的广泛担忧。批评者指出，强制披露社媒历史可能对国际旅行造成寒蝉效应，尤其影响记者、学者和持不同政见者。此外，如何确保海量数据的安全存储与合法使用，也成为公众关注焦点。目前该提案尚处于公众意见征询阶段，尚未正式实施。若最终通过，预计将影响每年数千万名赴美游客。支持者则认为，在恐怖主义和跨国犯罪风险上升的背景下，适度扩大数字背景审查是必要之举。然而，如何在国家安全与公民权利之间取得平衡，仍是政策制定者面临的核心挑战。
