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: RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag acts as a passive RFID tag, and the information it holds can be read with a proximity reader. This operation is performed when the RFID tag is attached to the object to be monitored. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag. The RFID tag then acts as an active RFID tag and starts to emit messages which can be received by a RFID reader.

Abstract: The present invention discloses a method, system and computer program embarked in a vehicle, for estimating traffic conditions based on positioning information exchanged with other vehicles using wireless communication. A method in accordance with an embodiment of the invention includes: receiving positioning information repeatedly broadcast by at least one vehicle, the positioning information for each vehicle including: information related to a current location of the vehicle; and information identifying the vehicle; calculating based on at least two successive locations of a same identified vehicle, a current speed and a current direction for the vehicle; and estimating current traffic conditions based on current location, speed and direction of identified vehicles.

Abstract: The present invention describes a RFID tag and a system and method involving a plurality of RFID tags. Each RFID tag is attached to an object (or to a structure or a person) on which the presence of a predefined fluid is monitored. In a first state, (absence of the monitored fluid), the tag is acting as a passive RFID tag, and the information it holds, (at least its identifier—ID), can be read with a proximity reader (a hand held or stationary/fixed reader). This operation is performed when the RFID tag is attached to the object (or person) to be monitored. At this stage a table associating tag ID, object name (or person name) and location (or any other information), may be built, and may be recorded so that information it contains is accessible by a control center. In a second state, whenever the monitored fluid appears on the tagged object, a fluid activated battery generates the electrical power which is used to power the RFID tag.

Abstract: The present invention provides a wireless service purchasing system used for getting a service provided by a service provider. In one embodiment, the system comprises a mobile device including a SIM card, wherein a RFID tag is integrated, the user being identified by the same identification number in both SIM card and RFID tag. The RFID tag is adapted to communicate with a service controller booth so that the user of the mobile device be authorized to get the service. The system comprises a service provider server adapted to receive a request when it has received the identification number from the RFID tag to verify whether an account associated with the user has enough credit to gain access to the requested service and to send back a reply to the service controller booth authorizing or denying the user access to the service according to whether there is enough credit in the account.

Abstract: A method of operating a phone is provided and includes receiving input to set a phone in a do-not disturb mode and to set a time period during which the do-not-disturb mode is activated and setting the phone accordingly, upon reception of an incoming call from a caller during the time period, activating a caller ID function of the phone, detecting a caller ID of the caller and searching for the caller ID in black- and white-lists. In an event the caller ID of the caller is stored in the blacklist, the voicemail function is activated or the incoming call is ended. In an event the caller ID of the caller is stored in the whitelist, an input of the password associated with the caller ID is requested, and, in an event the caller inputs the password, the ringing function is activated.

Abstract: A radio frequency identification (RFID) tag and a method and system for communicating with the RFID tag. The RFID tag includes a first and second structure respectively holding first data and second data that is complementary to the first data. The RFID tag does not include a microchip. An electromagnetic radio frequency signal is transmitted from an interrogator to the RFID tag. The interrogator receives, from the RFID tag, a response signal including third data being the first data or a combination of the first data and the second data. The interrogator extracts the third data from the response signal. A default value equal to the combination of the first data and the second data is stored in the interrogator. If the interrogator determines that the third data is unequal/equal to the default value, then a screen of the interrogator displays that the RFID tag is enabled/not enabled.

Abstract: A closure includes a closing member for sealing an opening of a pressurized container. The closing member may include a passive electronic sensor coupled thereto that includes a status register that may be readable by, for example, a RFID reader. The status register is responsive to a pressure change in the pressurized container caused by an insertion of the closing member into the opening or an extraction of the closing member from the opening. The status value in the status register indicates whether the pressurized container has been tampered with. An identification register may include a pressurized container identification encrypted with the private key of the manufacturer, which can be decrypted for comparing to identification on the pressurized container to identify tampering.

Abstract: In a client-server environment, a method and system are disclosed for granting transparency to the compulsory gateway of an IP network versus client applications run by the end-users connected on the IP network. When client applications have to access, on request of the end-users, server applications beyond the compulsory gateway this latter acts on behalf of them to access the requested remote resources eventually, relaying data between client and server applications. This is achieved without requiring any personalization on client end thus, guarantees that since gateway is becoming transparent to client applications all improvements and modifications brought to the IP network actually fully benefit to all end-users.

Abstract: A voting method. A ballot paper is received. The received ballot paper includes a recorded vote. The recorded vote includes candidate/party information for an election held on a voting day in a jurisdiction. The ballot paper includes a burnable radio frequency identification (RFID) tag including an on-tag fuse that is not blown.
