Title: AUTHENTICATION METHOD AND SYSTEM TO VERIFY THE AUTHENTICITY OF A PRODUCT
Abstract: Authentication method to verify the authenticity of products, comprising the steps of: a) associating to each product an electronic identification device having a unique identification code; b) selecting at least one piece of product information suitable to describe the product; c) associating to each identification code at least one respective and unique encryption key; d) encrypting the identification code and the product information; e) storing said encrypted content in the memory of the electronic identification device; f) obtaining the identification code and the encrypted content from the electronic identification device; g) decrypting the encrypted identification code using the encryption key corresponding to the obtained identification code; h) in case of correspondence between the decrypted identification code and the obtained identification code, decrypting the encrypted product information using the encryption key.

Claims: number: 1
text: Authentication method to verify the authenticity of products, comprising the steps of:
number: 2
text: Method according to the preceding claim, wherein steps c) to e), g) and h) are carried out by an authentication entity having an authentication server in which are stored the encryption keys corresponding to respective electronic identification devices, wherein step g) is preceded by a step (f1) of sending the identification code and encrypted content to the authentication server by means of the verification device and wherein step h) is followed by a step (i) of returning the decrypted encrypted content to the verification device.
number: 3
text: Method according to claim 1, wherein steps c) to e) are performed by an authentication entity and wherein steps g) and h) are performed by the verification device in which the encryption keys are stored, or to which it has access.
number: 4
text: Method according to any of the preceding claims, wherein each identification code is associated to a pair of encryption keys suitable to implement an asymmetric encryption algorithm.
number: 5
text: Method according to claims 3 and 4, wherein the authentication server uses a first key of each pair of encryption keys, and wherein the verification device uses the second key of each pair of encryption keys.
number: 6
text: Method according to any of the preceding claims, wherein the product information comprises a serial number or registration number and a description of the product.
number: 7
text: Method according to any of the preceding claims, wherein the product information comprises sensitive data, wherein to each verification device is associated one of a plurality of security levels, and wherein step h) requires providing the verification device the sensitive data decrypted only if the verification device has a predetermined security level.
number: 8
text: Method according to any of the preceding claims, further comprising a step 1) of writing, by means of the verification device, a piece of user information encrypted in the memory of the electronic identification device.
number: 9
text: Method according to the preceding claim when dependent on claim 2, wherein step 1) comprises the substeps of:
number: 10
text: Method according to any of the preceding claims when dependent on claim 2 or 3, further comprising the step of detecting the spatial position wherein the reading of the electronic identification device and the sending of the detected spatial position to the authentication entity took place.
number: 11
text: Method according to the preceding claim, wherein the detection of the spatial position takes place by acquisition, by the authentication server, of the location data provided by a GPS receiver of the verification device.
number: 12
text: Method according to any of the preceding claims, wherein, in case of correspondence between the decrypted identification code and the obtained identification code, an authentic product message comprising the product information is sent to the supplier of the product for activating a warranty on the authenticated product.
number: 13
text: Method according to any of the preceding claims, wherein, in case of a lack of correspondence between the decrypted identification code and the obtained identification code, the verification device or the authentication entity sends an alarm message, possibly containing the spatial position detected, to a server of a control entity.
number: 14
text: Authentication system to verify the authenticity of products, comprising:
number: 15
text: Authentication system according to the previous claim, comprising an authentication server provided with encryption means and decryption means, the verification device being suitable to send to said authentication server the identification code and the encrypted content, and wherein said decryption means are also suitable to return the decrypted product information to the verification device.
number: 16
text: Authentication system according to claim 14, comprising an authentication server equipped with encryption means, and wherein the verification device is provided with decryption means.
number: 17
text: Authentication system according to any of claims 14 to 16, wherein said encryption means are suitable to encrypt at least one piece of user information, and wherein said verification device is suitable to write said encrypted user information to the memory of the electronic identification device.
