Abstract
Secure identifiers for a series of articles are generated by encoding a characterising value such as a time stamp or serial number of each article with a pointer to a database entry such as a blockchain entry storing a range of valid characterising values, or other rule permitting the validation of each characterising value. When an identifier is challenged, the pointer is extracted and used to retrieve the rule, against which the characterising value extracted from the same identifier is tested.
Claims15
An apparatus for creating an identifier for a selected entity belonging to a defined set of entities, where each said entity has a characterizing value and where each said characterizing value complies with a common recorded rule, said apparatus comprising an encoder configured to receive a locator specifying where said recorded rule is to be electronically retrieved, and to encode the characterizing value of said selected entity together with said locator, wherein said rule specifies one or more of
- a maxima and a minima defining a range, or
- a particular mathematical progression, or
- a set of numbers defined in condensed form, or
- a mathematical or physical constant, or
- a mathematical operator applied to a defined value.
An apparatus for identifying a selected entity belonging to a defined set of entities, said selected entity having an identifier, said apparatus configured to:
- read said identifier, extract a locator from said identifier, electronically retrieve a recorded rule common to each entity of said set from a location specified by said locator, extract a characterising value from said identifier, and determine whether said characterizing value complies with said rule, wherein said rule defines one or more of
- a maxima and a minima defining a range, or
- a particular mathematical progression, or
- a set of numbers defined in condensed form, or
- a mathematical or physical constant, or
- a mathematical operator applied to a defined value.
An identifier for a selected entity belonging to a defined set of entities, where each said entity has a characterizing value and where each said characterizing value complies with a common recorded rule, said identifier comprising the respective characterizing value of said selected entity encoded together with a locator specifying where said recorded rule is to be electronically retrieved, wherein said rule defines one or more of
- a maxima and a minima defining a range, or
- a particular mathematical progression, or
- a set of numbers defined in condensed form, or
- a mathematical or physical constant, or
- a mathematical operator applied to a defined value.
A method of creating an identifier for a selected entity belonging to a defined set of entities, where each said entity has a characterizing value and where each said characterizing value complies with a common recorded rule, said method comprising:
- receiving a locator specifying where said recorded rule is to be electronically retrieved, and encoding the characterizing value of said selected entity together with said locator wherein said rule defines one or more of
- a maxima and a minima defining a range, or
- a particular mathematical progression, or
- a set of numbers defined in condensed form, or
- a mathematical or physical constant, or
- a mathematical operator applied to a defined value.
A method of identifying a selected entity belonging to a defined set of entities, said selected entity having an identifier, said method comprising:
- extracting a locator from said identifier, retrieving a recorded rule common to each entity of said set corresponding to said locator, extracting a characterizing value from said identifier, and determining whether said characterizing value complies with said rule wherein said rule defines one or more of
- a maxima and a minima defining a range, or
- a particular mathematical progression, or
- a set of numbers defined in condensed form, or
- a mathematical or physical constant, or
- a mathematical operator applied to a defined value.
