Claim 7:
8. A method for authenticating a portable diamond package with an authentication server, comprising:
providing, by an authentication device via a mobile device, a connection challenge to the authentication server, the authentication device embedded within the portable diamond package and located inside a package body, the portable diamond package having one or more diamonds located in the package body, wherein the package body is configured to reveal any tampering with the one or more diamonds located in the package body and the authentication device comprises a physical unclonable function (PUF) chip configured to output a unique algorithmic response;
establishing an encrypted connection between the authentication device and the authentication server responsive to receiving, at the authentication server, a response to the connection challenge from the authentication device;
generating, by the authentication server, an authentication challenge configured to verify the authentication device of the portable diamond package;
receiving, by the authentication server from the authentication device via the mobile device, an algorithmic response to the authentication challenge indicating authenticity of the portable diamond package and an image of the portable diamond package captured by a camera of the mobile device;
comparing, by the authentication server, cuts of a first set of diamonds in the image to cuts of a second set of diamonds in a reference image of the portable diamond package previously stored at the authentication server;
determining whether the algorithmic response from the authentication device match an expected response known to the authentication server; and
responsive to the algorithmic response matching the expected response and the comparison yielding a total match score deemed sufficient for authentication, sending a diamond package authentication confirmation to the mobile device.
