<p>Election provides an important opportunity to advance democratization and encourage political liberalization. Free and fair election is the foundation of every healthy democracy. But to have confidence, voters need to be assured that their elections are truly free, fair and secure. Now it is very essential to introduce recent technologies to conduct fair and smooth election. In this article we have introduced a thumb impression based vote casting method and geoencryption based intelligent cryptosystem that provides the security in EVMs and poll data of election. Our aim is to protect the unauthorized access of confidential poll data based on the coordinate system and cryptographic algorithm. GPS is the backbone of our voting system. Vote counting personnel must be present at a particular coordinate to properly decrypt the polling information. Geoencryption key is generated based on longitude and latitude of two particular coordinates. There are three modules in our cryptosystem—location and hybrid intelligence based key generation, symmetric key based authentication and double encryption. The different types of experiments and their results and analysis conforms that our technique is very efficient for location based data security.</p>
