For example, when the messages were imported from another device. They could be forged, but it is completely impossible to tell whether they were, unless the storage media used to copy them and the original device are available. | |
| Jun 11, 2022 at 4:24 | comment | added | Someone | Spoofing an email is so simple that spoofing an email to oneself may be the easiest way to forge an email. However, spoofing a text is much harder. In this case, the procedure @jiwopene described would probably be the easiest way to forge a text. (Of course, I do not recommend or endorse spoofing or forgery.) | |
| Jun 11, 2022 at 4:21 | comment | added | Someone | @PMF i think you are confusing spoofing and forgery. Yes, spoofing an email (making it show from someone other than the true sender, on a third party recipient's device) is much easier than spoofing a text. However, forging a message is different. This just requires the "recipient" to generate what appears identical to a message sent by the "sender," but not send it to someone else with this false impression. The copy on his computer may be inspected for authenticity, so it may need to pass that, but it does not need to be received on a third party's device with the false sender identity... | |

| Jun 10, 2022 at 17:25 | comment | added | bdb484 | Agreed. I doubt litigating at all would be cost-effective. They hypothetical seems to imply an absence of business savvy. Of course, all you have to do is add a few zeros to make the whole thing a lot easier to understand. | |
| Jun 10, 2022 at 17:21 | comment | added | Michael Seifert | @bdb484: And of course, hiring a data-forensics expert over a difference of 100€ might not be cost-effective. | |
| Jun 10, 2022 at 16:14 | comment | added | bdb484 | In the United States, at least -- and probably in the EU as well -- the easy answer is that each side will present whatever evidence it has and the court will decide who it believes. A well-advised client would hire a data-forensics expert to examine both phones to find evidence of tampering, but how they do that is probably a question better directed to another SE site. | |
| Jun 10, 2022 at 15:38 | comment | added | jiwopene | I would say that both are equally easy. Many phones or SMS apps allow importing and exporting all the messages. The import functionality can be used to add a custom message to the phone. | |
| Jun 10, 2022 at 15:28 | comment | added | PMF | Technically, it could be very different for SMS or E-Mail. The later can be forged much easier. | |
