164 results about "Electronic cash" patented technology

Electronic cash was until 2007 the debit card system of the German Banking Industry Committee, the association which represents the top German financial interest groups. Usually paired with a Transaction account or Current Account, cards with an Electronic Cash logo were only handed out by proper credit institutions. An electronic card payment was generally made by the card owner entering their PIN (Personal Identification Number) at a so-called EFT-POS-terminal (Electronic-Funds-Transfer-Terminal). The name “EC” originally comes from the unified European checking system Eurocheque. Comparable debit card systems are Maestro and Visa Electron. Banks and credit institutions who issued these cards often paired EC debit cards with Maestro functionality. These combined cards, recognizable by an additional Maestro logo, were referred to as “EC/Maestro cards”.

Certificateless partially blind signature method

The invention relates to a certificateless partially blind signature method. In the prior art, practicality of the partially blind signature method is low. The method of the invention is mainly used to solve the above problem. The method comprises the following steps that: 1) a secret key generation center randomly selects an integer sPKG as a private key in an integer multiplication group of mod q and stores secretly, and discloses a system parameter: (G1, q, 1, P, G2, e, H, h, QPKG); 2) a signer generates the partial private key s1 and a partial public key Q1, the secret key generation center generates the other partial private key S2 and the public key Q2 and sends to the signer through a safe authentication channel, and the signer acquires a private key pair (s1, S2) and a public key pair (Q1, Q2); 3) the signer carries out signature; 4) an authenticator verifies validity of the signature by using the public key pair (Q1, Q2) of the signer. By using the method of the invention, a demand to a certificate can be eliminated. There is no disadvantage of secret key escrow. A partial blind characteristic is possessed. Simultaneously, the method is simple and high efficient and possesses good practicality and security. The method can be used in an electronic cash transaction and electronic voting.

Cloud payment method, system and payment device thereof, and user terminal

The invention relates to the field of financial data processing, and provides a cloud payment method, a system and a payment device thereof, and a user terminal. The cloud payment method comprises thesteps of acquiring to-be-paid sum information which is input by a user; reading stored virtual financial card information, generating a two-dimensional code payment picture according to the sum information, wherein the two-dimensional code payment picture is used for scanning by an external payment device, and the payment device generates payment information and uploads the payment information toa bank payment server for finishing transaction. The cloud payment method, the system and the payment device thereof and the user terminal are advantageous in that low reconstruction cost is realized; the cloud payment method supports offline generation of the payment two-dimensional code and can be used for payment at the position with poor network environment or no network; the generated two-dimensional code picture can be transmitted to other persons for use and is equivalent with an electronic cash voucher, thereby realizing high convenience and preventing transferring cost caused by cashtransferring; the payment amount is input by a user and a condition of more money deduction caused by a trade company input error in code scanning is prevented; and furthermore restriction by carrying an NFC unit on an intelligent device is settled.
