java.lang.Object

cdac.medinfo.sdk.dcm30_04.services.basicapplicationlevelconfidentialityprofile.BasicAppLevelConfidentialityProfile

public class BasicAppLevelConfidentialityProfile
extends java.lang.Object

This Basic Application Level Confidentiality Profile addresses the following aspects of security: Data Confidentiality at the application level. This Profile is targeted toward creating a special purpose, de-identified version of an already-existing Data Set. This class provide methods to encrypt the Confidential Attributes present in the Data Set. Once the encryption algorithm and the secret key is specified by the user then Confidential Attributes in the data set are removed either by null values or the dummy values specified by the user. The original values of these data elements is added to the EncryptedAttributeSequence. This class also provides method to decrypt the Confidential Data Elements present in the Data Set i.e. re -identifying the Data Elements if the decrption algorithm and secret key is provided.
