Aspects of the invention relate to a customer authentication system for authenticating a customer making a request related to a customer account. The customer authentication system may include multiple application level data receiving and processing mechanisms for receiving customer requests and collecting customer data. The customer authentication system may additionally include a central authentication system for receiving the customer requests and customer data from the multiple application level data receiving and processing mechanisms, the central authentication system determining, based on authentication policy, whether the collected customer data is sufficient to authenticate each customer in order to fulfill the customer request. The central authentication system may return its conclusions and instructions to the multiple application level data receiving and processing mechanisms. The customer authentication system may additionally include a fraud policy system for centrally managing authentication policy implemented by the central authentication system.

A non-volatile semiconductor device has a memory cell array having electrically erasable programmable non-volatile memory cells, reprogramming and retrieval circuits that temporarily store data to be programmed in the memory cell array and sense data retrieved from the memory cell array. Each reprogramming and retrieval circuit has a first latch and a second latch that are selectively connected to the memory cell array and transfer data each other. A controller controls the reprogramming and retrieval circuits on data-reprogramming operation to and data-retrieval operation from the memory cell array. Each reprogramming and retrieval circuit has a multilevel logical operation mode and a caching operation mode. In the multilevel logical operation mode, re-programming and retrieval of upper and lower bits of two-bit four-level data is performed using the first and the second latches in storing the two-bit four-level data in one of the memory cells in a predetermined threshold level range. In the caching operation mode, data transfer between one of the memory cells selected in accordance with a first address and the first latch is performed while data transfer is performed between the second latch and input / output terminals in accordance with a second address with respect to one-bit two-level data to be stored in one of the memory cells.

Systems and methods are disclosed for providing a trusted database system that leverages a small amount of trusted storage to secure a larger amount of untrusted storage. Data are encrypted and validated to prevent unauthorized modification or access. Encryption and hashing are integrated with a low-level data model in which data and meta-data are secured uniformly. Synergies between data validation and log-structured storage are exploited.

A network element and method for marking traffic in a packet-switched data network which comprises a distributed hierarchical naming system and the network element. The network element comprises a marking rule store for storing marking rules, in which each marking rule is indicative of a quality of service level allocated to traffic on a connection impinging on the network element. The network element derives from the distributed hierarchical naming system quality of service level data for a connection, stores in the marking rule store a marking rule for the connection based on the retrieved quality of service level data and marks traffic on the connection in accordance with the marking rule.
