JPEGcrypto

Popis

JPEGcrypto safeguards JPEG images on your web site from ‚copyright violation‘. Advanced feature provides supremely strong protection with RSA-4096 bit crypto used by Gov and Mil organizations. Works with major Lightbox scripts cooperatively.

JPEGcryptoは貴方のウェブサイトに貼られたJPEG画像を著作権侵害から護ります。また、アドバンス機能では政府や軍でも使用される堅牢さのRSA-4096ビット暗号を用いて非常に強固な保護を提供します。主要なライトボックスとも協調的に動作します。

なお、日本語表示がWordPress本体のバージョンアップ等によって正常でなくなる事象についてはver2.6にて長期的対応を行いました。

Advanced feature

An image encrypted in JPEGcrypto format can not be saved as it is seen even when tried to be saved by analyzing html source code. Also displayed images can have dynamically-generated watermark that let you identify by whom and when copied it. This feature let you set ‚expiration date‘ and ‚granted website‘ with your images. When you pass an encrypted image to your clients, they can display your images only within your grant.

Encrypting and decrypting are done not with apps to be installed in your system but with our remote API server. All users have ‚free plan user‘ privilege with 100 calls/mth once the plugin gets activated. Please subscrive to our advanced plan when more professional service is needed.

Recenze

I have been looking for a good solution to block downloading images on my site by visitors who can look into page html. Though all developers I met said that 'being displayed means being downloadable', this plugin solved in an unique way with encryption and token. I'd say that another advantage of this plugin is its simplicity. I didn't have to install any application to my host that might make it unstable. Better if I can customize watermark drawn on my images. I'm a satisfied user.
