Abstract

In a world where digital information can be so easily altered it is essential to protect the original content of digital files from unauthorized changes. This is especially important with digital images such as maps or historical documents. If these images are provided to the world for research or public use then proof must be provided showing that no alterations have been made and that the image contains exactly what it should. The DS3 project will create a digital signature system that will uniquely sign digital image files and provide a process to validate each file according to the individual signature. The importance of this project is that it will provide reliable security and protect valuable data from unauthorized changes and tampering. By generating a digital signature for an image file, the data can be verified against that signature at any time to ensure that no changes have been made. Any changes in the file will be detected during the verification process.
