Is it possible to e-mail word, excel or powerpoint files that self-destruct after a set expiry time. Our business uses NDA agreements to manage confidentiality but we feel uncomfortable e-mailing Office documents that contain valuable corporate information. It would be reassuring if we knew they would automatically delete themselves after 3 months.
You could possibly use Visual Basic to only permit viewing of information if the system date is before a set date and you could also set it to delete data in a file using date criteria. However as per the initial post files containing macros are often classified as suspicious and it would have to be set up to force a user to enable macros to view the information - people and IT departments are very suspicious of such files.
I can set expiry date for a powerpoint plus adding a protection level of not being copied with its transitions and animations. Add to this, that it would be ran on any digital platform with no need for a powerpoint viewer or software. Also, add to it, that it would be html5 responsive.
For getting a free sample, don't hesitate to contact me :)
