Abstract: Method for direct access to information stored in the nodes of a packet switching network comprises the steps of: collecting the pointers, corresponding to which the information required for processing the packets belonging to one and the same flow is stored in each node of the network;—constructing a distributed linked data structure (DLDS) in which the pointers are contained inside packets (PI, P2, P3) that traverse the DLDS-aware routers constituting the path between sender (A) and receiver (B) of the flow;—use of the DLDS data structure for direct access to the information stored in a DLDS-aware router, using a pointer of the DLDS contained in the packet in transit;—selection of the pointer of the DLDS contained in the packet in transit based on its position inside said packet, said position being equal to the serial number of the DLDS-aware router in the flow path, and checking of validity by consistency tests.

Abstract: A method to search for affinities between subjects comprises registering a user with a certification authority, receiving first information relating to the user, memorizing the first information in a portable electronic device of the user, and synthesizing the first information by transmitting it to a user interface which processes the first information memorized. The method also comprises encrypting the first information and memorizing the first information encrypted in the portable electronic device, disseminating the first encrypted information to other portable electronic devices in geographical proximity, collecting second encrypted information relating to other users, sent from other portable electronic devices in geographical proximity and decrypting the first and second information encrypted at the certification authority.

Abstract: A wireless transmission and reception method for the transmission of sequences of signals between a first transceiver device and at least a second transceiver device, wherein the first transceiver device and second transceiver device are disposed outside a reciprocal direct radio-communication range. The method comprises a distribution step of a plurality of intermediate transceiver devices, disposed in a non-uniform manner between the first transceiver device and second transceiver devices as to form a linear transceiver chain. The method comprises a step of direct transmission, wherein a first sequence of signals is transmitted from the first transceiver device toward the second transceiver device at regular time intervals, temporally consecutive, able to define a synchronous times base in which each signal of the first sequence is re-transmitted from an intermediate device to an intermediate device immediately adjacent and successive along the path toward the second transceiver device.

Abstract: A method to search for affinities between subjects comprises the passages of effecting a step of registering a user with a certification authority (14), effecting a step of receiving first information relating to the user and memorizing the first information in a portable electronic device (11) of the user, and effecting a step of synthesizing the first information memorized in the portable electronic device (11) by means of transmission to a user interface (13) which processes the first information memorized.
