A content retransmitter receives information for receivers and forms an authorized list by transmitting authentication prompts, receiving authentication information, and adding receivers if the authentication information for the respective receiver is verified to match stored user information. Subsequently, the content retransmitter may receive content and broadcast the received content to some or all of the receivers on the authorized list. Additionally, the content retransmitter may store the received content in a storage medium and provide the stored content to receivers on the authorized list upon request. The user authentication information received from the receivers may be passwords, biometric information, and so on. The received content may be broadcast to a subset of the authorized list corresponding to users who are related to the content. The related users may be determined by examining metadata about the received content, facial recognition analysis of users present in the received content, and so on.
