Abstract
A method of secure management of data records stored in an RFID (Radio Frequency Identification) tag includes data fields whose contents are provided by different parties. Some of the data-fields contain public information data accessible to authorised end users. The data records are stored in encrypted form by encrypting data provided by different parties with different keys so as to set different access rights for contents providers and end users. The end users are supplied only with the keys allowing access to information data fields, whereas proprietary data are accessible only to the data owners. The keys are provided to the users in encrypted form.

A method of secure management of data records stored in an electronic tag, wherein said data records comprise data fields whose contents are provided by different parties, and wherein some data fields contain information data relevant to at least one RFID-based service and accessible to authorised end users, comprising the steps of:
- storing at least part of said data fields in encrypted form by encrypting data provided by different parties with different keys, each key being personal to the party providing the data for the respective field;
- and
- delivering different sets of keys to said end users and said different parties so as to set different access rights for said end users and said different parties, the different sets of keys being such that said end users are provided with the keys allowing access to the information data, each of said different parties having an exclusive access right to specific data provided by the party itself.
A system for secure management of data records stored in electronic tags, wherein said data records comprise data fields whose contents are provided by different parties, and wherein some data fields contain information data relevant to at least one RFID-based service and accessible to authorised end users, comprising:
- a plurality of electronic tags arranged to store respective data records where at least part of the data fields are in encrypted form, data provided by different parties being encrypted with different keys, each key being personal to the party providing the data for the respective field;
- a plurality of authorised end user equipment arranged at least to read the electronic tags;
- and
- at least one RFID-based service provider node and at least one information data provider node, which are said data providing parties and which are arranged to supply the end users and the other parties with different sets of keys so as to set different access rights for said end users and said parties, wherein each user equipment is arranged to store keys allowing access to the information data fields and each party can have exclusive access to specific data provided by the party itself.
An electronic tag storing data records comprising data fields whose contents are provided by different parties, some data fields containing information data relevant to at least one RFID-based service and accessible to authorised end users, wherein at least part of the fields of said data records are stored in encrypted form, wherein data provided by different parties are encrypted with different keys so as to set different access rights for said different parties and said end users, such that the end users are provided with the keys necessary for access to the information data, and any proprietary data is encrypted with a key available only to the data owner.
