Embodiments herein relate to a method and an information appliance device having a unique access card for preventing security breach in the information appliance device. A multimedia content server transmits a one-time access key to both the information appliance device and a user of the information appliance device. The user must input the access key to the information appliance device. The information appliance device verifies the access key and provides access to the user for the multimedia services, by activating a periodic activation key upon successful verification of the access key. Therefore, even if unauthorized user tries to skip the access key verification process through modification of access cards used in information appliance device, the unauthorized user cannot access the multimedia service due to lack of the periodic activation key required for activating multimedia service. Hence, security breach such as, cloning or duplication of the access cards will be minimized.
