Eproject tendering using email gateway system

ABSTARCT :

Tendering processes are considered to be a suitable mechanism for governments to fairly assign contracts for construction projects and procurement. The demand for efficiencies to be created in the process has resulted in a significant number of governments implementing e-tendering systems. E-tendering systems generally involve the submission of tender offer documents to a secure system hosted by the government (principal). An electronic environment presents obvious opportunities for collusion between principal and certain tenderers, fraud by tenderers and a minefield of legal uncertainties for fuelling protracted disputes. Critical examination of the security and legal requirements for e-tendering systems does not appear in the current literature. This paper identifies key security and legal issues to be addressed in the design of e-tendering systems, which may be included in e-procurement software, and proposes a new e-tendering architecture, using distributed trusted third parties which may be suitable for secure large scale operations such as the construction industry.

EXISTING SYSTEM :

? The existing architecture of popular-tendering system are introduced. Then a new architecture for a highly secure E-tendering system is proposed. ? The new architecture uses encrypted iris pattern as biometric attribute for authentication of tenderers participating in a tender. ? Iris authentication necessitates the existence of standardized iris image capture and encryption software along with the web camera that is built in the recent computer systems. ? Tenderers place their trust in the access control system employed by the principal to ensure that collusion or internal malfeasance by the principal’s users is difficult.

DISADVANTAGE :

? It minimises the reliance on one party thus reducing the chance of collusion and single point failure problems. Also, the documents for each tendering project are not stored on a third party system. ? This paper seeks to identify key security and legal issues to be addressed in the design of secure and legally compliant e-tendering systems. ? When these documents are kept and maintained electronically, legal issues arise as to how the contents and integrity of those documents can be proven in court. ? The same security issues and mechanisms such as secure communication, authentication and non-repudiation, access control and evidential integrity are relevant in this electronic tendering system.

PROPOSED SYSTEM :

• The proposed architecture uses Shamir threshold crypto system for securing the e-tender box and imposes BellLaPadula security model on the access rights of parties involved in the e-tendering system. • In the previous electronic tendering system, digital signatures were proposed as a technical means to ensure the non-repudiation of precontract communications. • In our proposed architecture DTTP is improved by using Biometric information for authentication, bell-LaPadula security model and shamir threshold crypto system for securing e-tender Box and other tendering documents. • In the proposed architecture, Biometric system is used for authentication .

ADVANTAGE :

? The demand for efficiencies to be created in the process has resulted in a significant number of governments implementing e-tendering systems. ? E-tendering systems generally involve the submission of tender offer documents to a secure system hosted by the government (principal). ? While an e-tendering system will be more efficient and cost-effective, the shift to an electronic environment presents several legal hurdles, in part because the law that governs electronic transactions is under-developed and lags behind the technology. ? However, as the tendering process is governed largely by contract law (as supplemented by constructions protocols or standards in some jurisdictions) many of the various gaps in the law may be remedied by explicit and detailed conditions of tender.
