Today, one of the popular products is mobile device because this device can be used anywhere and anytime. One of these mobile devices is a smartphone equipped with GPS services. In a condition, when a tour group is traveling sometimes there is one member missing. This paper proposes a solution by develope an application on a smartphone that can track the position of members by utilizing GPS technology. To maintain data security when sending GPS data, data is secured using RSA cryptography, IB-mRSA and group signatures so that only those members are able to access member GPS data. Group signatures is used to authenticate whether the lost members are part of the same group as other members or not. The Identity Based Mediated RSA algorithm (IB-mRSA) uses the ID of the member to do public key generation and private keys.
