Abstract

A method of producing pharmaceutical product packaging. The method includes, determining a serial number associated with a pharmaceutical product, generating, using the serial number, an identity, and generating, using the identity, a digital signature of at least part of the identity. The identity and signature are then used to generate coded data including a number of coded data portions, each coded data portion encoding the identity and at least part of the signature, the pharmaceutical product packaging being printed by printing at least some coded data, and at least one of the identity and the serial number.

Claims

1. A method of producing pharmaceutical product packaging, wherein the method includes, in a computer system:

determining a serial number associated with a pharmaceutical product;

generating, using the serial number, an identity;

generating, using the identity, a signature, the signature being a digital signature of at least part of the identity;

causing generation of coded data using the identity, the coded data including a number of coded data portions, each coded data portion encoding

the identity; and

,

at least part of the signature causing printing of, on the pharmaceutical product packaging;

at least some coded data, and

at least one of;

the identity; and

,

the serial number.

2. A method according to claim 1, wherein the identity is formed at least in part from at least one of:

a serial number of the pharmaceutical product;

an identity of the pharmaceutical product;

an EPC;

an identity of the packaging; and

,

an identity of a region of the packaging.

3. A method according to claim 1, wherein the method includes, encoding the entire signature within a plurality of coded data portions.

4. A method according to claim 1, wherein the method includes:

determining visible information relating to the pharmaceutical product;

determining a description, the description describing a layout of the visible information;

recording an association between the identity and the layout; and

,

causing printing of the packaging using the layout.

5. A method according to claim 4, wherein the description is indicative of at least one action associated with the pharmaceutical product, the action including at least one of:

providing information to a user;

updating tracking information relating to the pharmaceutical product;

performing a transaction relating to the pharmaceutical product;

authenticating the pharmaceutical product; and

,

receiving feedback from the user.

6. A method according to claim 1, wherein the method includes, in the computer system, communicating with a database, the database storing data relating the pharmaceutical product, including at least one of:

authentication data, including at least a key associated with a signature, the signature being a digital signature of at least part of the identity;

tracking data, the tracking data being at least partially indicative of tracking information including at least one of;

an owner of the pharmaceutical product;

one or more transactions performed using the pharmaceutical product;

a location of the pharmaceutical product; and

,

a location of the sensing device; and

,

product data, the product data being at least partially indicative of product information including at least one of;

a product cost;

a patient identifier;

a user identifier;

an owner identifier;

manufacture date;

batch number;

product manufacturer;

product distributor;

product supplier;

issue country;

ingredients;

storage conditions;

disposal conditions;

serial number;

expiry date;

effects;

side-effects;

conditions for use;

instructions for use;

links to further information;

contra-indications; and

,

dosage.

7. A method according to claim 6, wherein the method includes, in the computer system:

updating at least some of the data relating to the pharmaceutical product; and

,

generating the coded data using at least some of the data relating to the pharmaceutical product.

8. A method according to claim 1, wherein the method includes, in the computer system, receiving from a scanning system, in response to scanning of the packaging, information indicative of at least one of:

a source of the pharmaceutical product;

a pharmaceutical product type;

the identity of the pharmaceutical product; and

,

the serial number of the pharmaceutical product; and

,

9. A method according to claim 1, wherein the coded data is indicative of a plurality of reference points such that sensing of at least one coded data portion, by a sensing device, allows for determination of at least one of:

the identity;

at least one signature part;

a position of the sensing device relative to the packaging; and

,

movement of the sensing device relative to the packaging.

10. A method according to claim 1, wherein the identity is formed at least in part from at least one of:

a coded data portion identity;

an identity of the pharmaceutical product;

an EPC;

an identity of the packaging; and

,

an identity of a region of the packaging.

11. A method according to claim 1, wherein packaging includes at least one of:

a blister pack;

a bottle;

a bottle lid;

a label;

a box; and

,

a leaflet.

12. A method according to claim 1, wherein the coded data is substantially invisible to an unaided human.

13. A method according to claim 1, wherein the coded data is printed on the surface using at least one of:

an invisible ink; and

,

an infrared-absorptive ink.

14. A method according to claim 1, wherein the coded data is provided substantially coincident with visible human-readable information.

15. A method according to claim 1, wherein the coded includes a number of coded data portions, and wherein at least some of the coded data portions encode at least one of:

a location of the respective coded data portion;

a position of the respective coded data portion on the surface;

a size of the coded data portions;

a signature part;

a size of a signature;

an identity of a signature part;

units of indicated locations; and

,

at least part of a data object, the entire data object being encoded at least once by a plurality of coded data portions.

16. A method according to claim 15, wherein the data object includes at least one of:

Multipurpose Internet Mail Extensions (MIME) data;

text data;

image data;

audio data;

video data;

application data;
