Abstract: 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.

Abstract: Disclosed is a set top box (STB) configured to work with a smart card (SC) wherein the STB is authenticated by an operator who provides the smart card to a user using a One Time Password (OTP). The OTP is generated by the SC and sent via the STB to the operator through a user mobile device operatively coupled with the STB. The operator verifies the sender based upon registered mobile number of the sender, decrypts the received OTP and uses the decrypted OTP to transmit STB specific control messages to the STB and facilitate registration of the SC. Thereafter the STB can receive and decrypt channel data being transmitted by the operator. The SC, STB and the user mobile device have secure communication amongst each other after authentication of each other. Data sent between the user mobile device and the operator is encrypted.
