Visual sharing protection method for medical images

Due to frequent occurrences of information security event, the secure cryptographic techniques have attracted much attention in recent years. Image sharing is a secure and fault-tolerant method for protecting digital images, which can reduce the risk of information loss. In this paper, a new visual sharing method is proposed for protecting the security of the medical images. The patient information is firstly embedded into a medical image. Then the medical image with patient information can be divided into several shared images and protected by different participator. The original patient information and medical image can be retrieved by collecting the shared images. Experimental results can demonstrate the efficiency of the proposed method.
