    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.

    Abstract: A method and system for identifying an authentication status of a first item. An RFID reader transmits zero and a random number to a first RFID tag associated with the first item. The first RFID tag uses a hashing function to compute a hash (H1) of a concatenation of an identifier (Id1) of the first RFID tag, the random number, and a first secret key and sends the hash H1 to the RFID reader which then transmits the identifier Id1 and the random number to a second RFID tag. The second RFID tag uses the hashing function to compute a hash (H2) of a concatenation of the identifier Id1, the random number, and a second secret key and sends the hash H2 to the RFID reader. The authentication status of authentic or counterfeit is determined for the first item based on whether or not H1 is equal to H2.

    Abstract: A method and system for creating a recursive scalable template instance (RSTI) in an electronic data table having dimensions D1 and D2. A recursive scalable template (RST) associated with the RSTI is selected such that the RSTI is to be structured in accordance with the RST. A plurality of contiguous recursive element instances (REIs) of the RSTI is created in a memory of a computer system. The REIs are ordered and aligned along the dimension D1. Each REI has a same size along the dimension D2. Each RET includes at least one scalable template instance (STI). Each REI is structured according to a recursive element (RE) defined for the RST such that the RE includes at least one scalable template (ST). Each ST of the RE is instanced to generate an associated scalable template instance (STI) of an REI of the plurality of REIs.

    Abstract: Some "summary" information in a spreadsheet of a cell named range is preserved when some spreadsheet elements (like rows, or columns, or pages) are added or removed from the cell named range. A plurality of cells are identified by a cell address. A range summary cell is defined by specifying in a table a range summary cell address; a cell range address identifying an associated cell range; the range summary cell address is a function of the specified cell range address. In response to a user request for adding or deleting a spreadsheet element sharing a common cell address along at least one dimension with the cell range associated with the range summary cell updating in the table, the cell range address of the cell range associated with the range summary cell according to the user request; updating in the table, the range summary cell address according to the updated cell range address; moving in the spreadsheet, the range summary cell according to the updated range summary cell address; adding or deleting the spreadsheet element according to the user request; updating in the table, the cell range address after the addition or the deletion of the spreadsheet element; and updating in the table, the range summary cell address according to the updated cell range address.
