A Reversible Data Hiding Scheme Using Multi-layer Embedding for Intelligent Transportation Systems Images
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 10
Abstract
This paper proposes a lossless or reversible data hiding method which is based on the pixel difference histogram shifting for images in intelligent transportation systems (ITS) in spatial domain. Pixel differences are generated between a reference pixel and its neighbors in a pre-assigned block. After the difference histogram shifting, a large number of data such as vehicle's plate can be embedded into the host image and multi-layer embedding is used to improve the hiding capacity. The proposed scheme can extract the hidden data and recover the exact original cover image if we received embedding level (EL) number and the watermarked image via communication channel. The receiver can be various police forces who use this information to issue penalty ticket. The Simulation results demonstrate high degree of performance for the proposed method.
