One 是一个以隐私为核心的身份验证平台，用户只需验证一次身份，即可在多个应用程序中重复使用，且无需共享敏感的个人身份信息（PII）。 与传统方式不同——即用户需向不同服务商重复上传身份证件和自拍照——One 采用了用户自持加密技术。应用程序仅会收到所需的特定证明（如年龄确认或真人验证）以及审计记录，而原始身份数据始终保持加密状态，并由用户独家控制。 这一基础设施解决了两个核心问题：一是消除了用户在反复进行侵入式验证流程时所面临的阻力和安全风险；二是使企业能够在无需承担存储敏感个人数据责任的情况下，满足合规性要求。作为用户自持加密数据的底层架构，One 支持包括 KYC（了解你的客户）和私有 AI 转录在内的多种应用场景，确保敏感信息绝不会泄露给第三方数据库。归根结底，One 将范式从“平台托管数据”转变为“用户掌控身份”，从而提升了整个互联网的安全性和隐私性。
Some applications need to know that a user is old enough to use their product. Others want confirmation that there is a verified person behind an account. One returns the required identity proof in one tap, helping businesses meet their requirements without collecting personal data or putting users through a long and invasive verification flow.
Users verify their identity once, then reuse it across any application that uses One. No repeated ID uploads, and no new processor to trust with sensitive data. Applications receive only the proof a user approves, not their PII. Their data stays encrypted with a key only they hold, so even a breach of One would not expose readable identity data.
No. Age verification is simply the first privacy challenge that One was built around. The same infrastructure can confirm that an account belongs to a verified person without revealing who they are. At its core, One is a new primitive for persisting sensitive data under user-held encryption. It can power reusable identity presentation for KYC, private AI chat transcripts, and other applications that require persistence of sensitive data without surrendering custody to the platform.
One stores ciphertext: encrypted blobs created with a key held by the user. Never the underlying identity data. This includes government ID data, as well as the verified email associated with the account.
Only the requested proof and an audit record. For example, that a user is a verified person or is at least 18 years of age, and when the check was completed. No name, birth date, address, selfie, or ID image.
Applications increasingly need to verify aspects of their users’ identities, but traditional verification methods create a new privacy problem. Users upload IDs, selfies, and other PII to providers that can read and retain it, then repeat the process across multiple applications. That creates friction and spreads sensitive data across more databases and attack vectors. One was built around a new primitive to resolve that conflict: reusable identity data encrypted with keys only the user holds. Businesses get the proof they require, while users maintain their privacy and custody of their data. Read more: The Internet Should Be More Like a Liquor Store
