Binary pattern matchin, Difference Patch, and patching

Job Description:

I work in the automotive field, and as you already know there are firmware updates for cars, and every firmware update is diffrent. What iam looking for is a system/script, with a database, where it can store the firmware, and analyse it, and export the changes between these 2 binaries which i upload, and save it, [login to view URL] in future when i upload a similar firmware to automarically copy the changes, that where extracted ( if its similar firmware ofcourse ) so i assume it should look for patterns, or blocks/sectors on the ORIginal + [login to view URL] and to check if it can find them in the newly uploaded firmware, and if so, to apply the diffrence in the same places :)

1- Firmware A & Firmware B extract diffrences ( changes made ) from firmware B and store them

2- identify and store Firmware A & Firmware B & Diffrences in Database

3- upload new Firmware X

4- identify uploaded Firmware X and Compare in Database

5- If file Same or Similar to the one in database,

6- then Copy the diffrences into the Newly uploaded file Firmware X


Firmware 1 has , at sector 000037d is 10101010 bytes and Firmware 2 has, at sector 000037d has 11111111 bytes, when i upload firmware 3 which is for 70% similar to Firmware 1 i want the system to change in firmware 3 the sector 000037d from 10101010 to 11111111.
