Abstract: A method of marking a manufactured item is described, comprising: creating a unique product identifier for a manufactured item; creating one or more encryption keys; generating a secret key using the unique product identifier and the one or more encryption keys; generating a system noise value by performing a hash function on the secret key and the unique product identifier; generating a physical key from a measured physical property of the manufactured item; generating a physical noise value by performing a hash function on the physical key and the unique product identifier; generating a secure identifier derived from or incorporating the system noise value and the physical noise value; and placing a mark on the manufactured item, the mark comprising the secure identifier or an identifier derived from the secure identifier. Also described are methods of authenticating items marked in accordance with the described method.

Abstract: Exemplary embodiments are directed to a method and apparatus for storing data for a batch of manufactured items. The method comprises defining in a processor, using a lower limit identifier and an upper limit identifier, a range of unique item identifiers for the batch, wherein each manufactured item in the batch is allocated a unique item identifier falling within the range. The item identifiers are stored in allocated storage space. If an upper limit identifier is specified for each time interval, an amount of storage specified for all manufactured items during a production time period is calculated as a sum of a first product and a second product, the first product being a product of a production time and a size allocated to each upper limit identifier, and the second product being a product of the production time, a total number of manufactured items, and a percentage of unused identifiers.

Abstract: The invention relates to a system of automatic correction where certain errors are accepted while others are recognized as errors. This applies specifically to non-machine readable inputs or to optical character recognition when reading or transcribing codes. When entering certain characters, this system would allow certain similar character combinations and number of errors from that set while still maintaining integrity of identification codes.

Abstract: The invention relates to a method of defining a numerical basis by combining at least two different ranges of numbers which can be used to obfuscate an alphanumeric character. This basis can be used for product identification or other methods of creating unique tracking or identification numbers when used in combination with conversion functions.

Abstract: The invention relates to a system of obtaining authorization where there are multiple authorization modules. When an authorization is provided by a module, it is combined with a security token, digital signature or encryption identifying which module provided the authorization. To obtain a full authorization, multiple authorization modules may be required and these modules can be connected in parallel and or in series with each other.

Abstract: There is provided a method and system for authenticating a production of products. The method and system comprise determining if configuration data for the production run is authorized and, if the production run is authorized, generating a security token and associating the token with configuration data. The configuration data is digitally signed by generating a digital signature and associating the digital signature with the configuration data. The digital signature associated with the digitally signed configuration data is verified. Products are then produced in a production run according to the digitally signed configuration data, and the set of secure product identifiers is printed on the products according to the digitally signed configuration data.

Abstract: Manufactured goods are marked or labelled with a secure unique identifier. A central checking centre allows users to verify the authenticity of a particular good such as a cigarette pack or carton via any convenient interface such as the internet or a cell phone. A system of secret sharing allows secure authentication of each item and prevents code breaking or misuse.

Abstract: A method and apparatus for identifying manufactured items in containers, where each container is suitable for containing two or more units, and where the method comprises the steps of: associating each unit with a unique unit identifier, uniquely identifying each unit, allocating two or more units to be contained in each container, uniquely identifying each container, for each container, determining one or more ranges of unit identifiers of the two or more units allocated to the container, and storing, in a database, a container identifier for each container, each container identifier being coupled, in the database, to the one or more ranges of unit identifiers of the two or more units allocated to the container. There is also provided methods and apparatus for authenticating, tracking and tracing the units.

Abstract: A method and apparatus includes providing a cryptographic key, in an inactive state, to a point in a supply chain for manufactured items, providing the cryptographic key, in an active state, and an activation code for activating the cryptographic key, to a verification center, and providing the activation code to the point in the supply chain in response to the point in the supply chain transmitting information relating to the received cryptographic key. The method includes generating, at the point in the supply chain, an identification (ID) code for each manufactured item, derived from the cryptographic key in the active state and a dynamic key generated for each batch of manufactured items. Including providing the dynamic key for each batch of manufactured items to the verification center, marking each manufactured item with the ID code, and counting the actual or correct number of ID codes marked on the manufactured items.

Abstract: Exemplary embodiments are directed to a method and apparatus for storage of data for a batch of manufactured items. The method comprises defining, by a lower limit identifier and an upper limit identifier, a range of unique item identifiers for the batch, wherein each manufactured item in the batch is allocated a unique item identifier falling within the range. The number of unique item identifiers allocated to the manufactured items is smaller than the number of unique item identifiers in the range. The unique item identifiers allocated to the manufactured items are defined by the lower limit item identifier of the range, the upper limit item identifier of the range and an indication of those item identifiers in the range which are not allocated to a manufactured item.
