of luxury goods
October 2008
“Genuine fakes” are fake luxuryitems sold as authentic - theyare bad and rapidly multiplying
Thisis not thereal problem!
Genuine fakes are extremelyprofitable. They will “force entireindustries to rethink luxury or facerapid deflation”
9X ≈ potential marginof “genuine fakes”
30% ≈genuine fake“discount”

A digital certificate connectsone entity with its specific data
•Me My My name
•Me My My digital signature
...this particularbag…
(1 in the world)
…this particularcertificate…
(1 in the world) …to this particularcode/number
(attached to the bag)…
…is connectedthrough…
So…
…and…
…thisparticularcustomer…
…in which eachcode/bag is
associated to itscertificate
…and anaccount on a
website…
…has fourbags, each
with a code…
1.For each product put on the market, a specificcertificate is activated on the website
2.When a customer buys the product she logsin the website, (creates an account and)associates the code on the product to heraccount, either by typing it in or by reading it with hermobile phone
3.If the website confirms that thecertificate with that code exists and it is indeedassociated with that specific kind of product, then theproduct is real
Two bags might be identical, but theone with the certificate is certainlyreal and the other is certainly fake
The “remote certificate” solution linksthe product/digital-certificate to theholder of the account on the web
