A Novel Visual Cryptography Coding System for Jam Resistant Communication
A form of visual jam resistant coding is presented. Using Visual BBC, a modified form of BBC (Baird, Bahn, Collins) coding, it is shown that several images can be printed on clear plastic, such that when they are superimposed (i.e., a bitwise OR of the pixels is performed), the resulting image may look random, but the original images can still be recovered without any information about the orig...
متن کاملJam Resistant Communications without Shared Secrets
Information security is only attained when all four of the classic information assurance goals confidentiality, integrity, authenticity, and availability – are attained. The work presented focuses exclusively on the availability goal; in particular, maintaining the availability of the physical layer link in an omnidirectional wireless communications system. Hostile jamming is a direct attack on...
متن کاملHuman Visual System Based Scalable Video Coding and Communications
This paper introduces our recent research work on the development of a scalable foveated visual information coding and communication system, which follows two emerging trends in visual communication research. One is to design rate scalable image and video codecs, which allow the extraction of coded visual information at continuously varying bit rates from a single compressed bitstream. The othe...
متن کاملA Novel Weighted Visual Cryptography Scheme with High Visual Quality
Visual Cryptography (VC) has been developed to encode a secret image into n shares for n participants in the past decades, in which each share is treated with the same priority. However, the privilege for participants in a group is not always the same. In this paper, a weighted visual cryptography scheme is proposed such that each participant obtains her/his share with different weight accordin...
