The invention provides a method and system for privacy protection of block chain transaction. The method comprises: a transaction group is established between nodes of a block chain system, a user establishes an account at a node, and the node generates public and private key information of the account and then joining of a group is carried out; a transaction request node encrypts transaction information by using a broadcast encryption algorithm, carries out group signature processing on the encrypted transaction information, and then broadcasts the transaction information after broadcast encryption and group signature processing; a common non-account-recording node verifies the transaction information and then broadcasts the transaction information, an account-recording node decrypts thetransaction information and performs an intelligent contract to carry out account recording, broadcast encryption is carried out and then the information is recorded into a public account book, wherein the stored data are only allowed to be opened by the account-recording node, the transaction request node and an administration node. With the broadcast encryption algorithm and group signature technology, a privacy protection problem in the block chain system is solved and the traceability of the transaction is ensured.

A catheter 1 suitable for advancement through a body passageway of a patient. The catheter 1 comprises a catheter body 4 which is flexible to provide the necessary trackability for the catheter 1 to advance through a body passageway, and two stainless steel reinforcement wires 5 extending along the catheter body 4 which provide the necessary pushability to advance the catheter 1 through the passageway. The reinforcements 5 are positioned diametrically opposed to one another by approximately 180 degrees on opposite sides of the longitudinal axis of the catheter 1, and the catheter body 4 is relatively soft and twistable. This configuration enables the entire catheter 1 to spontaneously twist during advancement so that the reinforcements 5 orientate themselves along a plane of neutral bending during advancement of the catheter 1.

An integrity network is used to authorize electronic transfer of funds between two entities such as a caller or user and a third party. The network is accessed by a user via an electronic device that is capable of transmitting voice, such as a telephone. The network uses voice recognition functions, and optionally other information to uniquely identify the user and hence guarantee the integrity of transactions. In one embodiment, a user's phone number, a cellular phone serial number, or other code can be used as a security token. A person called via the network can further validate the identity of the user. Once validated, the user becomes a trusted member of the integrity network. Financial product can be provided to the trusted member with guarantees to the network of the identity of the trusted member.
