It won't....but as I've said at least a couple times (if you're so inclined) this should work. Do the following:How does a time stamp on some picture prove the items in said picture are the items currently in your possession?
- Take a picture of the mags, with the day's headline (paper) clearly visible. That effectively dates the photograph. Digital signatures can be altered, make no mistake about it. Yes, digital photos can be too but this works reasonably well.
- Print the pictures out, make three sets.
- Put each set in separate envelopes, seal them well, and mail them to yourself.
- DO NOT OPEN them when you get them. Leave them sealed, put them in a safe place.
- If ownership is questioned, you've got a postmarked (date) sealed letter, with photographs that have the date clearly identified by the newspaper also in the photos. Let a judge open the letter and see for himself.
No, mags don't have serial numbers and there's no way to prove the mags in the picture are the ones in question. But...it's very difficult to impossible to prove they aren't.
We did this when I was in the recording studio business with cassette tapes of music. Often called the "poor man's copyright" it has worked for people I know when questions arose.
Not saying everyone should run out and do this, but if you're so inclined, this is relatively easy to do and should hold up in court.
