Digital Content (PDF, Images, ZIP) Redistribution Prevention Strategies
I’ll share some redistribution prevention strategies for digital contents that I’ve been thinking about.
Want to prevent redistribution of digital content sold on an EC site after purchase.
The digital content file types I’m considering are:
One redistribution prevention strategy for PDF files is to insert the purchaser’s email address as a watermark on each page.
For image file redistribution prevention, you could embed the purchaser’s name or email address in the Exif data. While this doesn’t prevent redistribution, it can serve as a clue to identify who redistributed the content.

It seems there have been redistribution prevention efforts since the flip phone era.
For redistribution prevention with password-protected ZIP files, you could set a unique password for each purchaser.
It appears various companies are working on using blockchain technology to record ownership of digital content.
That’s all from the Gemba.
