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 authorized 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.
