摘要： The present invention relates to a method for tagging an object (101). The method comprising: measuring a physical characteristic pertaining to the object (101); determining an object reference unique identification (105) from the physical characteristic pertaining to the object (101); generating a cipher (108) using an encryption algorithm (107) having the object reference unique identification (105) as input data; tagging the object (101) with the cipher (108); and registering the cipher (108) and a key (110) for decrypting the cipher (108) in a ledger (111).
