Image Copyright Protection Guide
In today's world where images can be easily shared and copied online, copyright protection is a critical concern for creators and photographers. This article explains methods to protect digital image copyrights and practical protection measures using watermarking.
What is Digital Image Copyright?
Digital images such as photographs and illustrations automatically receive copyright protection at the moment of creation (under Japanese Copyright Law). No registration is required. However, even though copyright arises automatically, proving ownership in cases of unauthorized use is not always straightforward. This is where watermarking technology becomes valuable.
Methods to Protect Image Copyright
1. Metadata
Recording copyright holder names and license information in EXIF data. Easy to set up, but metadata can be easily deleted or modified, making it an unreliable protection method.
2. Visible Watermarks
Overlaying logos or text on images. Visually asserts copyright, but degrades the image's appearance and can be technically removed.
3. Invisible Watermarks
Embedding copyright information invisibly while maintaining image quality. Does not affect the image's appearance and is resistant to common image processing (resizing, compression, etc.). truvis uses this method.
4. Blockchain Registration
Recording works on a blockchain to serve as evidence of creation date and copyright holder. Resistant to tampering, but has a high barrier to entry for general creators.
Practical Copyright Protection with Watermarks
Embed Watermarks Before Publishing
Before posting images on social media or portfolio sites, embed a watermark using truvis. In case of unauthorized use, it serves as evidence of your copyright.
Use Different Payloads for Different Recipients
Setting different payloads for each client or media outlet helps identify the source in case of a leak.
Regularly Check for Unauthorized Use
Use Google Image Search and similar tools to regularly check if your work is being used without permission. If unauthorized use is found, watermark detection results serve as evidence for your rights claim.
Summary
There are multiple approaches to digital image copyright protection, but invisible watermarking is a well-balanced method that reliably embeds rights information while maintaining image quality. With truvis, you can easily start protecting your image copyrights without specialized knowledge.
Copyright Law Basics
Under Japanese copyright law, creative works are automatically protected from the moment of creation (no registration required). The protection period is generally 70 years after the author's death. Copyright includes reproduction rights, public transmission rights, adaptation rights, and more. Unauthorized infringement can result in civil and criminal liability. However, there are certain limitations on copyright, including copying for private use (Article 30), quotation (Article 32), and educational use (Article 35). Understanding these exceptions is important when dealing with digital images.
Response Flow When Copyright Infringement Is Discovered
Step 1: Preserve Evidence
When you discover infringement, first save screenshots and URLs as evidence. Run a decode using truvis — if your embedded payload is detected, it serves as strong evidence that you are the copyright holder.
Step 2: Contact the Infringer
If the infringer can be identified, contact them directly to request image removal. In many cases of unintentional unauthorized use, the issue is resolved at this stage.
Step 3: Report to the Platform
If the infringer does not respond, file a DMCA notice or copyright infringement report with the platform hosting the image (social media, web hosting company, etc.).
Step 4: Consider Legal Action
If the above steps don't resolve the issue, consult a lawyer about legal measures (injunctions, damage claims). Watermark detection results can serve as evidence in court proceedings.
