These 3 images are actually encrypted with JPEGcrypt and decrypted when it is displayed on this screen. Please try to save them and see how strong JPEGcrypto image protection is. If you are an IT engineer, use the Developer Tool equiped with Google Chrome or Firefox, or Fiddler for hacking to find out the HTML source and try to save the image. Even with these IT professional tools, you will find it extremely difficult to save the displayed image. In addition, watermarked information of "display expiration date", "displayed date", and "displayed client" are dynamically drawn thinly on the surface of the image so that you can let you track the person who reproduced.

Custom install solution

We install our 'encryption' and 'decryption' algorithm to your web server. This solution is suitable for web servers that need to be isolated from open internet. We investigate your system prior to implementation, and there are several cases that we can not implement JPEGcrypto to your system. Please contact us when interested.

For custom installation, you need to have an application server for encryption and decryption. The application server itself needs to be prepared at the expense of the user. We build an application server for custom encryption and decryption on the prepared server.
