How can I tell if a contract has been altered in two areas?

Hi which contract you mean ?

[Michael Bullo]

Can you please provide a lot more detail. Is this…
- A PDF with live text?
- A flattened image such as a JPEG or PNG?
- A HTML based page online?
- etc…

You need to be much more specific as @Michael Bullo already pointed out before anyone even can advise on the potential of a forensic analysis. Different formats require different approaches. If all you have is soem low-res photos of a paper contract then that's pretty much a pointless venture, but a high-res scan may expose tampering. Similarly, if someone hacked around in a PDF this can be detected, but other formats may not. Rinse repeat for whatever you have in mind.
