AUTHENTICATION METHOD FOR PHARMACEUTICAL PRODUCTS HAVING CODED PACKAGING
First Claim
1. A method for authenticating a pharmaceutical product, the pharmaceutical product being associated with packaging having disposed thereon or therein coded data including a number of coded data portions, each coded data portion being indicative of an identity of the pharmaceutical product and at least part of a signature, the signature being a digital signature of at least part of the identity and being encoded within a plurality of coded data portions, wherein the method includes:
- in a sensing device;
sensing at least one coded data portion; and
,generating, using the sensed coded data portion, indicating data indicative of;
the identity; and
,the at least one signature part;
in a processor;
determining, from the indicating data;
a determined identity; and
,at least one determined signature part;
authenticating the pharmaceutical product using the determined identity and the at least one determined signature part,wherein the coded data is arranged in accordance with at least one layout having n-fold rotational symmetry, where n is at least two, the layout including n identical sub-layouts rotated 1/n revolutions apart about a centre of rotation, at least one sub-layout including rotation-indicating data that distinguishes that sub-layout from each other sub-layout.

Abstract
A method for authenticating a pharmaceutical product, the pharmaceutical product being associated with packaging having disposed thereon or therein coded data including a number of coded data portions, each coded data portion being indicative of an identity of the pharmaceutical product and at least part of a digital signature of at least part of the identity. The method includes, using a sensing device to sense at least one coded data portion. A processor then determines the identity at least one determined signature part, and uses these to authenticate the pharmaceutical product. The coded data is arranged in accordance with at least one layout having n-fold rotational symmetry, where n is at least two. The layout includes n identical sub-layouts rotated 1/n revolutions apart about a centre of rotation. At least one sub-layout includes rotation-indicating data that distinguishes that sub-layout from each other sub-layout
