The method comprises the steps outlined below. At least one electronic digital data is received. A type of the electronic digital data is identified to retrieve a plurality of data fields according to the type of the electronic digital data, in which the data fields further comprises a plurality of data blocks. The data fields and the data blocks are analyzed such that they are categorized as at least one logic operation part and at least one data content part. A data-hiding process is performed on the data content part only to generate output electronic digital data and a subsequent analysis is performed on the output electronic digital data. ## Claims ### Claim 1 A method for performing anonymous testing on electronic digital data, comprising: receiving at least one electronic digital data;
