Use of Multi-Watermarking Schema to Maintain Awareness in a Teleneurology Diagnosis Platform

International audienceFollowing the tremendous evolution of transferring images through the Internet, it isnecessary to ensure security during this act and mainly for medical images.The application of multiple watermarking technique represents a solution to preserve the security of this data, on the one hand, and the traceability of medical diagnoses made by doctors, on the other hand. This falls under remote collaborative work.This technique is applied in the TeNeCi (Collaborative tele-neurology) platform. Thisproject allows practitioners to distribute the analyses of the medical image. In fact, we used the multiple watermarking technique in a wavelet field. The theory underlying this technique is to hide information in the medical image and to ensure at the same time its imperceptibility. The diagnosis made by the practitioner is the inserted data in theimage. The fundamental challenge of this paper is how to hide the total diagnoses of each practitioner in the image ensuring a good quality of the imageat the same time

Security of the Medical Media Using an Hybrid and Multiple Watermark Technique

International audienceThis paper proposes a new approach of multiple and hybrid watermark using two linked fields of insertion. This approach associates two different series of marks: one is sturdy guaranteeing the supervision of diffused media though the network and testifying to the identity of the owner of the medical image; the other series of marks, which is frail, insuring the integrity, the trace and the archives of medical diagnoses. In fact, this approach allows to benefit from the advantages of different insertion spaces (spatial and frequency field) and kind of two different fields of watermark. In the spatial field, the diagnosis of the doctor (frail marks) is inserted guaranteeing its records and its trace. In the frequency, the sturdy mark is inserted allowing to ensure the automatic control of the media through the network and testifying to the proprietor of the medical image
