Encryption and Security Analysis Using Modified Advanced Encryption Standard Based Algorithm in DICOM Images Using Histogram and Encryption Quality
Encryption is the effective way to have security in the data. During the transmission of medical information over wider networks for diagnosis, security is a very important factor. The standard images for transmitting the information in medical environment are the Dicom images. The structure of a Dicom includes both the header and information in a single file. This paper presents a novel technique for secured transmission of patient information which uses the preamble 128-byte data as a security metric. The parameter Encryption Quality is used as an evaluating parameter to access the security level.
