Data leakage from mobile phones and LBS is increasing with the exponential growth of technology, resulting in an innate risk of privacy threats. To address this issue, a novel method to protect user privacy is proposed in this paper. The proposed algorithms, namely SSET and SIMET, provide efficient means to encrypt the SIM and IMEI numbers respectively, thus protecting user identity. The reverse procedure to retrieve the numbers is provided by the algorithms SSDT and SIMDT and illustrated with examples.
