基于欺骗检测的CTS秘密图像共享
Secret Image Sharing Based CTS with Cheating Detection
摘要：
支票截断系统（CTS）是RBI实施的自动支票清算系统。CTS使用支票图像而不是支票本身进行支票清算，从而大大减少了周转时间。这种方法阻止了支票从提示行到付款行的物理移动。在CTS中，支票的数字图像使用标准的公钥和对称密钥保护，如RSA，三重DES等，这涉及到大量的计算开销和密钥管理。安全性也依赖于数学难题，仅是计算安全的.信息理论上安全的秘密图像共享技术可以用于CTS中，以安全有效地处理支票图像.本文提出了两个简单有效的秘密图像共享方案和基于这些算法的支票截断系统.在该方案中，提示行作为交易商，参与者为客户和付款行，交易商生成支票份额并分发给客户和付款行，在重构过程中，份额的有效性是重要的。该方案还提出了一种作弊检测方法，该方法使用散列技术来识别客户提交的任何无效份额。实验结果表明，与现有方案相比，该方案具有高效性和安全性。
英文摘要：
Cheque Truncation System(CTS) is an automatic cheque clearance system implemented by RBI.CTS uses cheque image, instead of the physical cheque itself, for cheque clearance thus reducing the turn around time drastically. This approach holds back the physical movement of cheque from presenting bank to the drawee bank. In CTS, digital image of the cheque is protected using standard public key and symmetric key encryptions like RSA, triple DES etc. This involves a lot of computation overhead and key management. The security also depends on the hard mathematical problem and is only computationally secure.Information theoretically secure, secret image sharing techniques can be used in the CTS for the secure and efficient processing of cheque image .In this paper, we propose two simple and efficient secret image sharing schemes and a Cheque Truncation System based on these algorithms . In the proposed scheme,the presenting bank is acting as the dealer and the participants are the customer, and the drawee bank.The dealer should generate the shares of cheque and distributes it to customer and drawee bank.The validity of the shares are important during the reconstruction process. The proposed scheme also suggests a method for cheating detection which identify any invalid shares submitted by the customers, using the hashing technique. The experimental results shows that the proposed scheme is efficient and secure compared with the existing scheme.
