PUBLISHING PATIENT DATA SET SECURELY THROUGH DIFFERENTIAL PRIVACY VIA WAVELET TRANSFORMS

Every organization stores a required data in the digital form. This data needs to be published due to the mutual benefits or due to the government rule. This data also has significant research value. While publishing a data in its original form, there is loss of privacy of the individual record. To avoid this, we can use ε -differentialprivacy. Dwork provides a simplest way to achieve this. But it does not work well with razge count query. In this paper we have used Privelet+ method using array based implementation for wavelet transforms. This method shows better result than the Dwork method for the range count queries.
