The digital forensics used in the corporate world primarily in relation to litigation involving computer- related evidence such as civil matters, breach of contract, breach of confidence, and so on, has recently been gaining a great deal of attention. In order to support the digital forensics in a stand-alone environment, we proposed a system named "Dig-Force (Digital Forensic System with Chaining Signature for Evidence)" that uses a USB device with a smart card function and a hysteresis signature based on digital signature technology. In the present paper, we discuss an application suitable for our system, and pro-pose a practical use such as surgical procedures where misconduct and mistakes are not permissible. In such a scene, not only data from a keyboard but also data from a camera are required. We also report on a program for the Dig-Force system that uses a function suitable for a camera application. Moreover, we show the result of an experiment that applies this program. The result shows the system is useful for keyboard as well as camera applications.
