This paper analyzes threats and attacks in the Internet Commerce world and suggests schemes to detect the attacks when they occur, prevent further loss once an attack is detected, and provides remedial corrective actions so as to enable victims of commerce-related attacks to resume conducting business transactions. Some commerce based transaction recovery mechanisms are suggested to recover from losses these attacks may have caused. Suitable cryptographic primitives and protocols that realize an anonymous complaint and an anonymous receipt are developed to provide trust and security against e-commerce related attacks.
