Abstract: A method, device, and system for conducting trusted payment transactions including establishing a trust relationship between a first mobile computing device and a second mobile computing device. The first mobile computing device may initiate a payment transaction with a point-of-sale device, communicate with the second mobile communication device to retrieve payment information from the second mobile communication device, and complete the payment transaction with the point-of-sale device using the payment information. The second mobile computing device is configured to verify the user and identity of the first mobile computing device prior to providing the payment information. Communications between the mobile computing devices may be encrypted using pre-determined encryption techniques.

Abstract: A method and system to enhance the protection of the data in an user equipment and secure real time streaming of the data in the user equipment is disclosed. The method and system includes sending request by at least one user to access at least one application server. The user is provisioned to download a appropriate CMSC and a mapper into the user equipment from the application server. The method and system further comprises user sending request via an IMS network to download a data to the user equipment. The data is encrypted in the application server and is downloaded into the user equipment. The mapper identifies the appropriate CMSC, which may decrypt the data. Further, the data undergoes double decryption in real time within the user equipment before being presented in user interface. The double decryption is provisioned using the valid CMSC downloaded in the user equipment.
