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.
Claims16
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 recorded rule, said apparatus being adapted to receive a locator for said recorded rule, and to encode the characterizing value of said selected entity together with said locator.
An apparatus for identifying a selected entity belonging to a defined set of entities, said selected entity having an identifier, said apparatus being adapted to:
- read said identifier,
- extract a locator from said identifier,
- retrieve a recorded rule corresponding to said locator,
- extract a characterising value from said identifier, and
- determine whether said characterising value complies with said rule.
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 recorded rule, said identifier comprising the respective characterising value of said selected entity encoded together with a locator for said recorded rule.
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 recorded rule, said method comprising:
- receiving a locator for said recorded rule, and
- encoding the characterising value of said selected entity together with said locator.
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 corresponding to said locator,
- extracting a characterising value from said identifier, and determining whether said characterising value complies with said rule.
