Abstract: A Web-based multi purpose contractual management system can provide support to contractual process workflows for different types of contractual process of unilateral, bilateral or multilateral contracts. These processes can be done on-line i.e. Web-based without the need for all actors to be synchronously present with respect to both time and space. Different contractual processes of initialization, negotiation, agreement, signing (witness), and archive are managed within the application securely by analyzing data-flow between actors, ushering actors to perform their duties in a timely manner and employing appropriate cryptographic techniques on every step of the way. The implementation must deliver a management system that provides operational properties of authenticity, privacy, trustworthy, reliability, verifiability, and linkability.
