Sammanfattning
Surveillance images are often used for forensic purposes. Being possible evidence in court or in an insurance claim, it is crucial that the authenticity of images can be verified. The path between the actual camera and the forensic investigator who is to examine the surveillance images may be quite long and involve many people, causing it to be difficult to establish a chain of custody. The usage of digital signatures can improve this situation by using cryptography to authenticate digital images. The sooner the signature is created in the chain, the better. Ideally, the signature should be created inside the surveillance camera itself, and this dissertation covers a method for that.
