A digital watermark is called fragileif it fails to be detectable after the slightest modification. Fragile watermarks are commonly used for tamper detection (integrity proof). Modifications to an original work that clearly are noticeable, commonly are not referred to as watermarks, but as generalized barcodes.
You need a digital scanner. That's all... just put the photos in, scan them as a .jpg file and store them, and review them with any photo software.
A digital camera is hardware.
Digital watermarking is used to avoid illegal copying of images by integrating a more or less visible copyright notice on the photo. Most image converters (see reference link fro an example) can overimpose digital watermarks on the photos.
A digital camera is hardware. The computer program inside that runs it is software. ----------------- Both, alone the camera (hardware) would not work without the program (software) inside it.
A watermark is a recognizable image or pattern embedded into paper or digital content, often used to signify authenticity or ownership. In physical documents, it is usually created during the manufacturing process and can be seen when held up to the light. In digital media, watermarks can be logos or text overlaid on images or videos to deter unauthorized use. Overall, watermarks serve as a protective measure against copyright infringement.
