Abstract

A method of dispensing a pharmaceutical product, the pharmaceutical product being associated with packaging having disposed thereon or therein coded data, at least some of the coded data being indicative of at least an identity of the pharmaceutical product. The method uses a computer system which receives indicating data from a sensing device, in responsive to sensing of the coded data. The computer system uses the indicating data and a dispensing database to determine at least one criterion for dispensing the pharmaceutical product. The computer system causes the pharmaceutical product to be dispensed if the at least one criterion is satisfied.

Claims

1. A method of dispensing a pharmaceutical product, the pharmaceutical product being associated with packaging having disposed thereon or therein coded data, at least some of the coded data being indicative of at least an identity of the pharmaceutical product, the method including:

sensing by a sensing device at least some of the coded data and generating indicating data indicative of the identity of the pharmaceutical product based on the sensed coded data, the coded data being 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 center of rotation, at least one sub-layout including rotation-indicating data that distinguishes that sub-layout from each other sub-layout;

receiving by a processor the indicating data from the sensing device;

determining by the processor based on the indicating data at least one criterion for displaying the pharmaceutical product; and

causing by the processor the pharmaceutical product to be dispensed based on the at least one criterion being satisfied.

2. A method according to claim 1, wherein the method includes communicating by the processor 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.

3. A method according to claim 2, wherein the method includes causing by the processor display of at least one of:

results of authentication;

tracking information; and

,

product information.

4. A method according to claim 2, wherein the digital signature includes at least one of:

a random number associated with the identity;

a keyed hash of at least the identity;

a keyed hash of at least the identity produced using a private key, and verifiable using a corresponding public key;

cipher-text produced by encrypting at least the identity;

cipher-text produced by encrypting at least the identity and a random number; and

,

cipher-text produced using a private key, and verifiable using a corresponding public key.

5. A method according to claim 1, wherein the at least one criterion is indicative of an intended recipient of the pharmaceutical product, and wherein the determining step includes sub-steps of:

determining identity data indicative of an identity of an individual requesting the pharmaceutical product;

comparing the identity data to the at least one criterion; and

,

determining the at least one criterion to be satisfied when the identity of the individual is the same as the identity of the intended recipient.

6. A method according to claim 5, wherein the sensing device includes a storage device for storing the identity data.

7. A method according to claim 1, wherein the coded data 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.

8. A method according to claim 7, 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;

contact data;

information;

business card data; and

,

directory data.

9. A method according to claim 1, wherein the at least one criterion is indicative of at least one of:

an intended time for dispensing the pharmaceutical product;

an intended date for dispensing the pharmaceutical product; and

,

an intended location for dispensing the pharmaceutical product.

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 the coded data includes at least one of:

redundant data;

data allowing error correction;

Reed-Solomon data; and

,

Cyclic Redundancy Check (CRC) data.

12. A method according to claim 1, wherein 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.
