A transmission method and a transmission system are provided. The transmission method is for communicating an electronic device and a wireless earphone. The wireless earphone has a normal mode and a sleep mode. The transmission method includes the following steps. If the wireless earphone works on the normal mode, then the wireless earphone continuously transmits the data of synchronization signals to the electronic device. If the wireless earphone works on the sleep mode, then the wireless earphone stops transmitting the data of synchronization signals to the electronic device, and simulates the data of synchronization signals.

Transmission method and transmission system

A data access control system and a method thereof is disclosed. First, the master key is divided into n subkeys to be kept by n holders, by way of secret sharing. The master key reconstruction procedure utilizes the shared secret with the subkey holders to obtain m subkeys (1<m<n) and then reconstructs the master key, using the (m,n)-threshold scheme. The system then uses the master key to access the data. Thus, m subkeys are required to reconstruct the master key in order to amend or read the data in the system.
