Claim One:
1. A computer-readable storage medium storing computer-executable instructions to process one or more instances of suspect media that include a plurality of data elements, the computer-executable instructions comprising: dividing the one or more instances of suspect media into non-overlapping consecutive blocks, wherein each of the non-overlapping consecutive blocks includes at least one of the data elements; identifying a first quantized block of the data elements, wherein the first quantized block includes a first subset of the data elements; determining that the first subset of the data elements is eligible to be embedded with steganographic data when the first subset of data elements are identified within one of the non-overlapping consecutive blocks; identifying a second quantized block of the data elements, wherein the second quantized block includes a second subset of the data elements; determining that the second quantized block of data elements is ineligible to be embedded with steganographic data when the second subset of data elements are identified in two or more of the non-overlapping consecutive blocks; requantizing the first quantized block and the second quantized block of data elements; comparing statistics resulting from requantizing the first quantized block with further statistics resulting from requantizing the second quantized block; and assessing whether the instances of suspect media are embedded with steganalytic features based on comparing the statistics to the further statistics.
