ABSTRACT:
A method for protecting digital information includes: converting a protected address range into a plurality of address blocks based on a preset conversion unit, and generating an address block rearranging rule using the address blocks as a parameter; when it is desired to load data into an address batch of the protected address range, converting the address batch into a plurality address blocks based on the conversion unit; and locating rearranged addresses of the address blocks in the protected address range according to the address block rearranging rule, and loading the data into the rearranged addresses. Thus, the data can be stored in the address batch scatteredly, and the protected data cannot be recomposed into the original correct data when stolen.
