Location based services are immensely popular. Many location based services depends on current location. But determine the past location is important. Malicious users may access the restricted resources by cheating on their locations. Spatial Temporal provenance Assurance with Mutual Proof (STAMP) scheme used to find the past location of the users effectively. At the time of finding location proof there is a chance to occur collusion attack between the users and users may try to change their identity to get the location proof. So Collusion Resistance is one of the important aspects in the STAMP scheme. In order to defend against colluding attacks, present the Ciphertext Policy Attribute-Based Encryption (CP-ABE) method. Location sharing is the method to share the user's location in secure manner. To provide secure sharing of location proof Blowfish algorithm is used. Extensive experimental results show that CP-ABE can effectively defend against colluding attacks and Blowfish algorithm can effectively share the location proof in secure manner.
