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: System for enhancing the security of the e-mails transmitted from a sender (10) to a receiver (12) over a data transmission network such as Internet wherein a Message Transfer Agent (MTA) (14) associated with the sender is in charge of transmitting over the network an original e-mail sent by the sender. The MTA associated with the sender includes a message splitting means (16) adapted to divide the original e-mail into a plurality of chunks according to a predetermined algorithm and a predetermined list of relay MTAs (20, 22, 24) to which are forwarded the plurality of chunks. The system comprises a chunk assembly agent (28) for receiving from the relay MTAs the plurality of chunks and re-assembling them by using the predetermined algorithm in order to re-build the e-mail before sending it to the receiver.

Abstract: Electronic system for managing the payment by the users of car parks comprising at least one kiosk (16, 18 or 20) used by a user to perform a payment corresponding to the period of time the user's car is authorized to be parked in a car park (10, 12 or 14) and a payment device located located inside the user's car having a screen visible from outside for displaying the time limit until which the car is authorized to be parked. The kiosk and the payment devices of the cars parked in the car park are connected by a wireless link so that the kiosk detects a car when it is parked within the car park and registers the car identification, the kiosk transmitting to the payment device the time limit to be displayed on its screen after the user has performed the payment corresponding to the amount of time for which the car will be authorized to be parked.

Abstract: The data transfer process involves using nodes where incoming packets are enqueued prior to being forwarded toward their destination. Clipping operations are performed within the nodes by selectively discarding enqueued packets. The packets include an EC field initially loaded to indicate whether the corresponding packet is eligible for clipping or not within the network. The packets from a source terminal are made eligible for clipping on a periodic basis. The sequence is made to designate as eligible for clipping every other packet from the source. Each packet includes a bit position (PC) to be used to bar the clipping of the corresponding packet. If required within a network node, a non eligible for clipping packet may be clipped, with the prevent clipping bit of next from same source being set during its transfer through the node, whereby the next packet is prevented from any subsequent clipping along its path within the network.

Abstract: A surveyor's mark and a method of forming the mark. A tag is embedded in a head. The head is removably assembled to a stick. The head is configured to be above a ground when the stick is planted in the ground. The head includes a tag. The tag in the head includes an identification number whose value identifies the tag and indicates if the head is disassembled from the stick. If the stick is planted in the ground and the head is above the ground, then pulling the head in an attempt to pull up the mark from the ground results in changing the value of the identification number in the tag from a first code value to a second code value that differs from the first code value.

Abstract: A computing system and computer readable medium storing computer instructions are disclosed, which when the computer instructions are executed, enables a computer system to manage data using a file name on a computer system having a graphical user interface and a file system storing files with a file hierarchy. The computer instructions comprise, in part, entering a command from an application to create a file; displaying the file hierarchy; allowing a user to select at least one folder; saving data in a first file having a file name in one selected folder; in each of the other selected folders, creating a shortcut file having the same file name and containing a pointer to the first file; and creating a hidden file in the folder containing the first file, the hidden file containing a list of pointers to the shortcut files.

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.
