Tamper Detection in Multi-format Image Databases Using Fragile Watermarking

Storing and using multimedia data for various commercial usages has increased enormously, which in turn needs a way to secure data from intentional attacks. Watermarking is one of the securing methods that can wrap any content and detect the attack, if any on decoding. This paper proposes a watermarking technique for image databasses that might contain images in any format like JPEG, BMP, PNG, etc. We propose to store image data in encoded form and compare the content against the watermarked for its authenticity.
