为什么人脸、指纹这类生物特征不能随便给？
Why shouldn’t you give away biometric data like face or fingerprint?
密码是秘密，可以改，泄露一次只废一次；人脸和指纹不是秘密，它本就暴露在明处，又绑在人身上，换掉等于换人。系统存的也不是口令而是用于比对的模板，一旦外流你无法重新注册一张脸，冒用就没有终点；何况验证靠相似度阈值，不必完美还原也能过闸。风险不在这次验证，而在一次授权变成长期身份，所以它只宜作多因素之一、尽量在本地比对。
A password is a secret: it can be changed, and one leak spoils it once. A face or a fingerprint is no secret - it is on display all the time and tied to one body, so replacing it would mean replacing the person. What the system keeps is not a passphrase either, but a template made for comparison; once that leaks you cannot enrol a new face, and the impersonation has no deadline. Matching also runs on a similarity threshold, so an attacker need not reconstruct you perfectly to pass the gate. The danger lies not in this one check but in a single authorisation turning into a lifelong credential, which is why biometrics belong as one factor among several, matched locally wherever possible.

为什么给App“最小必要权限”更安全？
Why is giving apps 'minimum necessary' permission safer?
过度授权让App收集你的位置、通讯录用于画像或转卖，按需开放、用完收回能降低泄露风险。
Over-permission lets apps harvest location and contacts for profiling or resale; granting only what’s needed reduces leak risk.

为什么路由器和摄像头要用强密码、改掉默认密码？
Why change default passwords on routers and cameras?
很多设备出厂弱口令会被黑客扫描利用，入侵后可能被用来偷拍或发动攻击，设置强密码是第一道防线。
Many devices ship with weak default passwords that hackers scan and exploit for spying or attacks; a strong password is the first defense.
