Abstract: There is a need for secure query processing system due to the explosive growth of Internet- capable and location-aware mobile devices. The existing system consists of an untrusted location based service provider, which is also not unified and no user identity. In order to overcome these problems a secure query processing system is proposed which consists of a certificate authority (CA), data owner, location-based service providers (LBSPs) and system users. The data owner uploads its encrypted details and sends request to the CA for authentication, while LBSP collects and aggregates data sets from the data owner. The user sends query to the LBSP to perform the secure query processing. Based on the query the data is processed. In order to make the application more secure, the encrypted data will be decrypted by the user based on the CA’s private key and the user’s identity from the user. Thus by using the certificate authority we provide a secure location-based services to the system users.
