Society has long seen anonymity in many forms such as suggestion boxes, unsigned letters and blocked calls. In the online world, the protection of users' anonymity, when performing some online transactions, is an important factor in the acceptance and use of several Internet and web services. Solutions for minimizing release of personal information can be based on many proposed cryptographic techniques for providing anonymity. In this thesis, we describe the design and implementation of an online feedback system employing an anonymous authentication mechanism based on blind RSA signature scheme. The proposed system prevents malicious evaluators from assuming multiple identities. It also maintains the anonymity of the evaluator even against an abusive authority that has access to the evaluation servers. Based on our design, the authority, responsible for the evaluation process, can be held accountable if it blocks any user's feedback. The system also prevents malicious evaluators from sending multiple evaluations for the same evaluatee. Finally, the developed system is generic enough, user friendly and allows the administrator to change the evaluation form to fit the assessment of essentially any type of function or performance
