Claim 6:
7. The method of claim 5, wherein comparing data in the respective blocks in both the updated executable file and the base executable file further comprises:
computing, by the one or more processors, each digest of each block in the base executable file;
for each specific block in the updated executable file:
computing, by the one or more processors, a first digest of the specific block in the updated executable file;
comparing, by the one or more processors, the first digest with each digest of each block in the base executable file;
in response to the first digest being the same as a second digest of a second block in the base executable file, determining, by the one or more processors, the specific block and the second block are paired blocks; and
in response to the first digest being different from any digest of any block in the base executable file, determining, by the one or more processors, the specific block is in different blocks; and

obtaining, by the one or more processors, the delta file based on the paired blocks and the different blocks.
