OBJECT ORIENTED MODELING FOR AUTHENTICATION OF CERTIFICATE IN E-LEARNING USING DIGITAL WATERMARKING
Main Article Content
Abstract
As the popularity of e-learning system is increasing day by day, the question of security is also becoming a matter of concern. While the administrator sends certificate or any essential document in an e-learning system via internet or intranet, if the hacker can reach the document, can easily change or destroy it, which makes a bad impact on the corresponding e-learning institution. Through digital watermarking along with some cryptography techniques, the administrator can make this kind of transmission very secure. The advantage of object oriented modeling of any system is to reduce the maintenance cost, improve reliability and flexibility, code reusability etc. To achieve these advantages, we wrapped our proposed model in object oriented modeling utilizing the benefits of object oriented analysis and design.
