Authentication method for pharmaceutical products having symmetrically 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 encoding orientation-indicating data comprising a sequence of an integer multiple m of n symbols, where m is one or more, each encoded symbol being distributed at n locations about a centre of rotational symmetry of the layout such that decoding the symbols at each of the n orientations of the layout produces n representations of the orientation-indicating data, each representation comprising a different cyclic shift of the orientation-indicating data and being indicative of the degree of rotation of the 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 a n-fold rotationally symmetric layout. The layout encodes data comprising a sequence of an integer multiple m of n-symbols. Each encoded symbol is distributed at n-locations about a center of rotational symmetry such that decoding the symbols produces n-representations of the data each comprising a different cyclic shift of the data.
