System and method for dynamic registration and utilization of QR-code identifiers on physical media

A method for dynamically registering and utilizing QR-codes, the method comprising:

• (i) generating a QR-code representing a unique URL, which is comprised of a domain, and a base-code;
• (ii) attaching, applying or associating the QR-code to a person, animal or thing, or onto a physical medium adapted to be applied to or associated with a person, animal or thing;
• (iii) providing a specific user;
• (iv) providing a smart-phone for use by said user, comprising an optical hand-held scanning device for scanning the QR code;
• (v) using said smart-phone to scan the QR-code for the first time for the specific user, whereby the user is directed to a registration website by the scanning device or by a second device in communication with said scanning device;
• (vi) enabling the user to register the QR-code with a specific registered action associated with the person, animal or thing;
• (vii) storing the registration information in an information storage means;
• (viii) performing the registered action upon subsequent scans of the QR-code by other users, and
• (ix) allowing said specific user who originally registered the code to update aspects of the registration;
• wherein the base code comprises a first element and a second element, and wherein one of said elements of the base code categorizes the QR-code into different application types and one of said elements of the base code represents a cryptographic signature;
• and further, wherein a third element of the base code is the signature and is generated using a hash of the rest of the base code concatenated with a secret key.
