Copyright infringement occurs when someone uses, reproduces, distributes, or displays copyrighted material without the permission of the copyright owner, in a way that violates the exclusive rights granted to the creator. Here are some key points regarding copyright infringement:
### 1. What Constitutes Copyright Infringement? - Unauthorized Use: Copying or distributing copyrighted works without permission. - Public Performance or Display: Showing copyrighted content (movies, music, books, software) in a way that violates the owner's rights. - Derivative Works: Creating modifications, adaptations, or derivative works without permission. - Commercial Exploitation: Using copyrighted material for profit without proper licensing.
### 2. Examples of Copyright Infringement - Downloading or sharing movies, music, or books illegally. - Using copyrighted images or music in YouTube videos without permission. - Copy-pasting text from books, articles, or research papers into a published work without citation or authorization. - Selling merchandise with copyrighted logos or characters without a license.
### 3. Consequences of Copyright Infringement - Legal Actions: The copyright owner can sue for damages. - Fines & Penalties: Courts can impose heavy financial penalties. - Takedown Notices (DMCA in the U.S.): Websites hosting infringing content may receive a Digital Millennium Copyright Act (DMCA) takedown request. - Account Suspension: Platforms like YouTube, Instagram, or Facebook can suspend or terminate accounts involved in infringement.
### 4. Defenses Against Copyright Infringement - Fair Use (U.S.) / Fair Dealing (UK, Canada, Australia): Limited use of copyrighted material for commentary, criticism, news reporting, teaching, or research. - Creative Commons & Open Licenses: Using content with proper licensing. - Public Domain: Works whose copyrights have expired or were never copyrighted.
### 5. How to Avoid Copyright Infringement - Use royalty-free or Creative Commons-licensed content. - Get explicit permission from the copyright owner. - Credit the source when required. - Create original content instead of copying others.
Images are extensively utilized in educational materials due to their efficacy in conveying complex concepts. However, unauthorized use of images frequently results in legal issues related to copyright infringement. To mitigate this problem, we introduce a dual-module system specifically designed for educators. The first module, a copyright infringement detection system, employs deep learning techniques to verify the copyright status of images. It utilizes a Convolutional Variational Autoencoder (CVAE) model to extract significant features from copyrighted images and compares them against user-provided images. If infringement is detected, the second module, an image retrieval system, recommends alternative copyright-free images using a Vision Transformer (ViT)-based hashing model. Evaluation on benchmark datasets demonstrates the system's effectiveness, achieving a mean Average Precision (mAP) of 0.812 on the Flickr25k dataset. Additionally, a user study involving 65 teachers indicates high satisfaction levels, particularly in addressing copyright concerns and ease of use. Our system significantly aids educators in creating educational materials that comply with copyright regulations 1)
