I built an app to check if the person calling you is really them

A while ago I read about a company that wired $25M after a video call with deepfaked colleagues. Around the same time, voice-cloning scams started targeting parents: "Mum, I lost my phone, can you send money to this number." Social engineering at its best. The usual advice is a family safe word. Problem: it never changes, and once someone hears it, it's useless. So I built Hongi. How it works: - You pair with someone once by scanning a QR code (or sending an invite link) - After tha

AI 分析

痛点:深度伪造视频和 AI 语音克隆冒充亲友或同事实施诈骗,传统家庭暗语固定不变、一旦泄露即失效,缺少实时、防重放的真人身份核验手段。

目标用户:有老人/子女需防诈骗的普通家庭、需要防范商业邮件与转账欺诈的中小企业财务人员,以及银行、酒店等需要对来电身份做认证的机构。

证据:A while ago I read about a company that wired $25M after a video call with deepfaked colleagues... 'Mum, I lost my phone, can you send money to this number.'... Organisations (banks, hotels) pay to get listed in a verified directory... Getting people to pair *before* they need it is the hard part.

变现:个人端免费获客,向银行、酒店等机构收取「认证目录收录/年费」做 B2B 变现;后续可加企业版团队管理、API 核验接口订阅。

MVP:两周内做一个纯前端 Demo:基于 TOTP 算法在两端离线生成每 30 秒轮换的「双词口令」,用二维码配对,通话时互相念词核对;先做 iOS 单端 + 分享链接,不做后台目录。

竞品:Truecaller(来电识别,非防深伪)、各家银行 App 内置的安全口令/设备绑定、Pindrop(企业级语音防欺诈)

摘要:一位独立开发者用 React Native + Expo 做了 Hongi,通过二维码配对后两端每 30 秒生成两个不同口令、通话中互念核对,防止冒充者复述。个人免费、无广告,计划靠银行/酒店付费收录进认证目录变现。作者坦言最大难点是让用户在「出事前」先完成配对,需求真实但付费与采用均未被验证。
