Abstract:
A method and computing systems for refreshing, from a server, objects locally stored by a client device remotely connected through a communicating means to said server. The client device send a request for refresh message and a list of object identifiers and the digest of the object itself stored in its local storage. The server, after checking the deals the client device has subscribed to, sends back a refresh answer message with the objects stored locally in the client device and which needs to be refreshed. According to the deals to which the client device has subscribed, the server will also send new objects and will send a special code to specify to the client device to delete objects which are no more part of the deals.
Abstract:
A method is disclosed to create files in a file system hierarchy in a way which facilitates their retrieval. The method of the preferred embodiment allows to manage a file by creating , retrieving, deleting, copying and moving the file in a file hierarchy as displayed through the graphical user interface provided with the operating system. The file is saved in one folder under a file name and a possibility is given to the user to save the file under the same file name or different file names in different folders which are all in relation with the context of the file creation. The user will multiply his chances to retrieve the file in different folders when he desires access it later on. The principle is to create a real file in a first designated folder and to create shortcut files in the other folders. The list of shortcut files is saved as a hidden file in the same directory as the real file. The advantage of the invention is to take benefit of the shortcut function available in most operating systems.
Abstract:
An expiration management method and system. The method includes transmitting by an RFID tag reader within an enclosure, a plurality of continuous timing signals. The enclosure comprises a container comprising a product and an RFID tag. The RFID tag comprises data indicating a first state for the RFID tag and a first time period. The RFID tag reader receives the data and generates a first time stamp. The RFID tag reader transmits a first message commanding the RFID tag to enter a second state. The RFID tag reader transmits the first time stamp and generates a second time stamp. The RFID tag reader transmits the second time stamp. The RFID tag reader receives results from a comparing process performed by the RFID tag. The RFID tag reader performs a function indicating the results.
Abstract:
A method for authenticating an item comprising an RFID having a memory for storing an identifier and a secret key, and a built-in hashing function, is disclosed. According to the method of the invention, the output of the RFID of the item to be authenticated is compared with the output of the RFID of a genuine item. To that end, a random number is transmitted to the item to be authenticated with zero as parameters. The RFID 's identifier, the random number, and the secret key are concatenated and use as input of the built-in hashing function that result is output with the RFID identifier. The RFID 's identifier and the random number are then transmitted to the RFID of the genuine item that returns its identifier and the output of the built-in hashing function computed with the RFID 's identifier of the item to be authenticated, the random number, and the secret key. If the results of both built-in hashing functions are identical, the item is authenticated else, it is counterfeiting.
