Summary:A method of protecting confidential data using a non-sequential hidden block mechanism is provided, including the following steps of: (a) configuring the size of the confidential file; (b) the electronic host reading the capacity of the physical memory; (c) configuring the capacity of usable physical memory space; (d) the electronic host writing confidential data; (e) generating a random access lookup table (LUT) of address space; (f) using a random function to generate random address within a certain range and storing into the random LUT sequentially; and (g) sequentially mapping the logic addresses of the confidential data to the random LUT, and writing the mapped physical addresses to the physical memory blocks. Through the above steps, the mass storage device, such as no-volatile memory and hard disk, can store the data non-sequentially to achieve the object of confidential data protection.
