A simple, easy, and safe electronic settlement system is provided. A user terminal such as a cellular phone is wirelessly connected to a synchronizing server at a counter of a retailer. A cashier terminal of the retailer connects to the synchronizing server via a private line and so on. The cashier terminal receives a transaction identifying number in order to identify the transaction from the synchronizing server, and notifies to a user. A user inputs the transaction identifying number to the user terminal and transmits the transaction identifying number to the synchronizing server. The synchronizing server completes a transaction between the virtual cashier terminal and the user terminal, both of which are corresponded to each other by the transaction identification number. The cashier terminal authenticates the user intermediated by the synchronizing server. The user can complete a settlement without telling his or her personal information such as a credit card number or a password to a retailer. A security of the system is improved.

Techniques for providing communication services include provisioning a packet network connection that has packet channels, each of which is independently capable of carrying narrowband signals so as to emulate a private line circuit. A narrowband private line that traverses the packet network connection using a particular one of the packet channels is established. Delays that might otherwise be introduced as a result of packetizing the narrowband signals can be reduced. Private lines that traverse the packet network connection using other packet channels can be added or removed without adversely affecting the existing lines. Additionally, a narrowband communication line that traverses a channel in a first virtual circuit connection in a packet network can be rolled over to a channel in a second virtual circuit connection in the packet network. The latter technique can improve the use of available bandwidth and can be applied to non-private line applications as well.

A secure token access distributed database system to provide verification of someone's or something's identity quickly and securely is provided, wherein such database and system is readily scalable from local to nationwide to worldwide use. The system specifically addresses the use of an authenticated user identification (ID) where any accepted authentication scheme can be employed in combination with a number of secure enabled databases connected by any means, including LAN, WAN, Internet, and dedicated lines, to provide value-added data in real-time at the main point of security contact. Furthermore, the instant invention provides a concept by which a potentially unlimited number of secure enabled databases containing various kinds of data potentially useful to a requesting entity, are either connected by some network means, or exposed to the Internet through a secure connection. Data transfer may also be bi-directional. As part of the security incident information exchange, data may not only be received by the requesting entity, but the provider database may also receive updated information. Requests may be progressive in nature. Data contained in a response from one database may cause the requesting application to send out a new, modified request for the ID based on that data. Moreover, continual update of the incident data may continue even after sufficient information has been received to make a security decision, e.g., grant entry. If subsequent data arrives that could affect that decision, it may provide authorities and security personnel with timely data and an opportunity for appropriate and effective action.

A data processing apparatus in which DMA transfer is performed. When a processor in a data processing unit outputs a first request to read data managed by a data management unit, a receiver-side DMA controller outputs a second request for DMA transfer, from the data processing unit to the data management unit through a dedicated line.

Data transmission for writing data into a shared memory is performed by a high-speed dedicated line provided between each processor and the shared memory. When a processor performs writing to a shared memory space, the processor notifies an update notification bus corresponding to the conventional global bus, to which address the update is to be performed. The other processors which have detected this notification inhibit access to that address and wait for the write data to be sent to the address via the dedicated line. When the data has arrived, the data is written into the corresponding address. Here, the data is also written into the corresponding address, thereby maintaining the cache coherency. Moreover, when transmitting a write address, it is necessary to acquire the bus use right while data transmission is performed by using the dedicated line, which significantly reduces the time required for acquiring the bus use right.

The invention relates to a disaster-tolerant system for processing telephone traffic data, which consists of a main operation system and a standby system. A synchronous private line is arranged between the main operation system and the standby system. The standby system and the main operation system have the same internal software and hardware structure and external network connection. The main operation system is an actual operation system, and the standby system synchronously operates with the main operation system. When normally processing data, the main operation system generates synchronizing information and transforms the synchronizing information to the standby system. The standby system receives the synchronizing information and implements the treatment process, but does not transmit the result. After the main operation system has system failure or disaster, the standby system temporarily takes over production, and after the acquired data is processed, the file is transmitted into the external network. The invention realizes disaster tolerance by adopting the mode that the systems are embedded into the processing flow and the transmitted data is greatly reduced. Moreover, the mode adopted by the invention has far lower requirement on bandwidth than the disaster-tolerant mode based on intelligent storage bottom copy. The standby system and the main operation system can complete switching over in a short time.
