THE TRANSFER OF DIGITAL CURRENCY ENCRYPTION KEYS THROUGH THE PROCESS OF ISSUANCE, VALIDATION AND DEVALIDATION OF A PHYSICAL INSTRUMENT WITH MULTI-FACTOR AUTHORIZATION, AND THE PHYSICAL INSTRUMENT OF ENCRYPTION KEYS FOR DIGITAL CURRENCY TO CARRY OUT THIS TRANSFER TECHNOLOGY

Abstract

A method for transferring digital currency encryption keys through the process of issuing, validating and devaluing a physical medium with multi-factor authorization, where said medium distributed on the market as a blank and to which belongs a second authorization factor (5A) securely stored by the manufacturer or embedded in the medium in the form of a frame with a seal that cannot be removed without a trace, is loaded by an issuer using a SW application for issuing the medium and based on a first authorization factor (2A) generated by the issuer, an identifier of the medium and other data, an address is derived and transmitted to the issuer to which it sends the balance of the digital currency in an amount equivalent to the nominal value of the medium.Then, through the online service for issuing digital signatures, the issuer requests the granting of the digital signature after completing all the formalities, in particular the authenticity of the instrument piece and with the transferred sum of the digital currency balance being equal to the nominal value of the instrument. The issuer then combines the digital signature with the first authorization factor using the instrument issuing software application and adds this data to the instrument in particular by printing, handwriting or as a sticker. In this way, it activates the instrument and makes it transferable to the next holder, even repeatedly. The recipient performs a visual inspection and verifies the instrument using a software application for verifying the instrument, in particular the digital currency balance.Then, this SW application verifies the authenticity of the digital signature (3A) after loading the first authorization factor (2A) and the digital signature (3A), the first authorization factor (2A) is validated, and the recipient compares the digitally signed data with the data visible on the medium. Subsequently, the recipient loads, using the software application for redeeming digital currencies, all authorization factors (2A and / or 5A) available on this new duly issued physical medium in an active state, possibly adds other authorization factors known to him, and composes and authorizes an electronic transaction on the digital currency network for the redemption of funds in electronic form to the recipient's private address.The result is the transfer of digital currency encryption keys through the process of issuing, validating and devaluing a physical medium with multi-factor authorization, and consequently the execution of a payment transaction between the issuer and the final recipient in digital currency. Part of the result is also a visibly devaluated medium. A physical medium of encryption keys for digital currency for carrying out the transfer of encryption keys through the process of issuing, validating and devaluing the physical medium described in claim 1, wherein said medium is made of a flat base body of any shape (in particular geometric shape) and solid materials (in particular / plastics, paper, metals and their alloys) with one of its main flat surfaces being identified by the unique alphanumeric identifier (1).This medium contains, depending on a particular model, applications of anti-counterfeiting protective features, with one or both of the main flat surfaces having a frame (2) for receiving the first authorization factor (2A) and a frame (3) for adding the digital signature (3A).
