signed

Definition

Three senses, disambiguated entirely by context. In mathematics it means carrying a sign — a signed distance function encodes inside versus outside as negative versus positive, the standard representation for implicit 3D surfaces. In security and systems it means cryptographically signed so tampering is detectable, while in ordinary prose signed up just means registered.
