A computing device provides a resonance algorithm to process digital signal data according to a principle of physical resonance. The resonance algorithm determines a division length n of digital signal data according to a frequency f1 of an audio signal to be detected and a sampling frequency f2, which is used for sampling the digital signal data by a coder. Furthermore, the resonance algorithm divides the digital signal data into a serial of data segments by the division length n, and obtains enhanced digital signal data by accumulating a number m of the data segments.

Computing device and signal enhancement method

A data security protection method generates dynamic encryption keys and dynamic decryption keys for a host and a client during data transmission between the host and the client. The host stores a host initial key K, and determines a host key Kusing a one-way hash function based on the host initial key K. The client stores a client initial key K', and determines a client key K&#x2032;using the one-way hash function based on the client initial key K&#x2032;. Original data Ris encrypted as encrypted data Xusing the host key Kbefore being sent to the client. The client decrypts the encrypted data Xusing the client key K&#x2032;, to obtain the original data R.
