Secure Data Management Device and Method
First Claim
1. An item, attached to a product which is subjected to a chain of logistics, for collection of data and for communication with a host computer via a data network, the item comprises an electronic module including a unique identity identifying each item individually and a non-retrievable cryptographic key and the host computer is storing the corresponding identity and cryptographic key, characterized by that the electronic module stores collected data related to the product or use of the product in a non-volatile memory and a cryptographic operation is performed on the collected data when exchanged between the item and the host computer in order to ensure identity, authenticity, integrity and confidentiality of the collected data.

Abstract
The invention concerns a secure data management device and a method for providing communication between a remote device in a chain of logistics and a host computer via a data network which ensures the identity, authenticity, integrity and confidentiality of collected information. This is provided by an item which is attached to a product subjected to a chain of logistics. The item can collect information about the product or use of the product and communicates such information to a host computer via a data network in a secure manner, which will assure the recipient of the information that the communication is made with the correct item and that the information communicated has not been manipulated and the transmission is protected from eavesdropping. The information collected by the item can be generated by sensors integrated or attached to the product.

13. A method for gathering data generated by a multitude of products being part of a logistic chain and each product having an item attached to it, the item comprising an electronic module for communicating with a host computer via a data network and said electronic module comprising a unique identity and a non-retrievable cryptographic key, characterized by that
the generated data is collected and stored by a memory means of the electronic module; -
the cryptographic key performs an encryption operation on the generated data;
the generated data is transmitted together with the unique identity to the host computer via a data network;
the host computer is decrypting the transmitted data with a cryptographic key stored in the host computer together with the unique identity given to the item. - View Dependent Claims (14, 15, 16, 17, 18)
