Cloud Computing Security with Identity-Based Authentication Using Heritage-Based Technique
More organizations start to give various types of distributed computing administrations for Internet clients in the meantime these administrations additionally bring some security issues. Presently the many of cloud computing systems endow digital identity for clients to access their services, this will bring some drawback for a hybrid cloud that includes multiple private clouds and/or public clouds. Today most cloud computing framework use asymmetric and traditional public key cryptography to give information security and common authentication. Identity-based cryptography has some attraction attributes that appear to fit well the necessities of cloud computing. In this paper, by receiving federated identity management together with hierarchical identity-based cryptography (HIBC) with cloud heritage technique, not only the key distribution but also the mutual validation can be rearranged in the cloud
Computers in Diagnostic Nuclear Medicine Imaging - A Review
Digital computers are becoming increasingly popular for a variety of purposes in nuclear medicine. They are particuiarly useful in the areas of nuclear imaging and gamma camera image processing,radionuclide inventory and patient record keeping. By far the most important use of the digital computer is in array processors which are commonly available with emission computed systems for fast reconstruction of images in transverse, coronal and sagittal views, particularly when the data to be handled is enormous and involves filtration and correction processes. The addition of array processors to computer systems has helped the clinicians in improving diagnostic nuclear medicine imaging capability. This paper reviews briefly therole of computers in the field of nuclear medicine imaging
