Abstract:
When high-resolution, copyrighted photographic images are displayed on the Internet, they must be protected from being copied by screen capture or by file. HTML and a Web browser alone do not provide protection, e .g., screen capture by a standalone program can not be prevented. This paper describes a Java system that provides copy protection for Internet display of photographic images organized into albums. Included is protection aga inst image file copy and against effective screen capture. The system involves three software components, two used by an administrator to build albums and a one used by client viewers. The system supports any number of albums, provides image annotation, zooming, and searching, requires no server-side software, maintains client privacy, and, using Java Web Start, does not require clients to install any software locally. The system is being used to maintain albums of noncommercial high-resolution historical and contemporary photos
