We present a layered architecture for secure e-commerce applications and protocols with fully automated dispute-resolution process, robust to communication failures and malicious faults. Our design is modular, with precise yet general-purpose interfaces and functionalities, and allows usage as an underlying secure service to different e-commerce, e-banking and other distributed systems. The interfaces support diverse, flexible and extensible payment scenarios and instruments, including direct buyer-seller payments as well as (the more common) indirect payments via payment service providers (e.g. banks). Our design is practical, efficient, and ensures reliability and security under realistic failure and delay conditions.

This research aims at the CEO's (chief executive officer) incentive-reward system and investigates 456 companies that have come into the market. The structure and level of agent reward are analyzed. And the problem in the incentive-reward mechanism is brought forward. The agent's payments are poor comparing to their contributions. And stock is not a primary incentive. Bonus compensation is still the dominant incentive means. By questionnaire and interview, it was fond that matriel need was rank first among these CEOs'needs. These foundinds indicate that the agents' payment is too poor to work as an effective incentive. The corporation's agent incentive is not enough in fact. The two reasons about this problem lie in our institutions and traditional opinions about commerce. To solve this matter, we must establish a scientific and reasonable evaluation system and incentive-reward system. At the same time, the market system and corporation management mechanism are absolutely need.
