Abstract: This invention relates to methods, computer program code and apparatus for improved RFID tagging systems. We describe a module for configuring an RFID system comprising a plurality of RFID readers, said RFID system operating in an environment comprising a plurality of RFID tagged entities, the module comprising: code to enable a user to build an interface for defining a state map for said RFID system, said state map comprising a plurality of states representing information about tagged entities within the environment and transitions between said plurality of states; a transition logic module storing transition logic controlling transitions between states wherein said transition logic module is connected to said interface so that transition logic for said state map is defined using said interface; and a database for storing said states, said transitions and said defined transition logic.

Abstract: The present invention relates to RFID systems. In particular, the invention relates to an RFID system having enhanced security of communication between a tag and a tag reader. In a first aspect of the present invention there is provided an RFID system comprising at least one RFID reader; control means for communicating with an RFID tag by public-key encryption via said reader; at least one RFID tag adapted to encrypt a response to a transmission by a reader using a public-key transmitted to the tag; unauthorised broadcast detection means for detecting a broadcast made by an unauthorised reader; and alert means for providing an alert in the event a broadcast by an unauthorised reader is detected.

Abstract: A system and method for executing a document in a verifiable manner is described where the system displays an electronic document, receiving an identifying characteristic of a party executing the document. The system then adds an electronic form of the identifying characteristic to the electronic document and receives confirmation that the electronic form of identifying characteristic is authentic. On receipt of confirmation the system digitally signs and stores the electronic document.
