| Abstract: |
Today one of the directions of data technology development is a visualization, i.e., a representation of something - a physical process, a phenomenon, etc. in a form convenient for viewing. Visualization became widespread in many practical areas, one of which is the digital forensics. In the latter one began to use the visual evidences very actively. In case of any crime the visual evidence plays a vital role for a realization of the punishment inevitability principle. However, the visual evidences have a digital nature and therefore require specific protection measures to be applied to stand any kinds of its modifications. In some cases, one might need to protect privacy of the visual evidence, particularly, if it contains information constituting a state or commercial secret or personal data.
On the other hand, the visual evidence has to confirm the fact of violation while not allowing an offender to desist from any action or inactivity confirming this fact. In this case, the judge may ask for visual evidence to make her/his mind about the fact of violation of the law.
The paper discusses the major ideas and approaches to practical implementation of the cryptographic method to ensure the integrity and confidentiality of images (visual evidence) - so called the method of Melnikov-Jones. In addition, this method can be used for formation and protection of visual evidence in the resolution of legal disputes (to assure non-repudiation). This method is based on the preparatory scrambling and several subsequent geometric permutations of pixels of the image via its decomposition using a triangular lattice that virtually eliminates any possibility of malicious distortion. In other words, any attempted modification of the visual document will be detected. |
