  • Publication number: 20130151562
    Abstract: The use of the known feature amounts results in a low level of accuracy in finding similar files. To deal with this problem, the similar file determination process of this invention involves dividing a file, while at the same time changing a file dividing condition, and repeating this dividing operation until the total number of divided pieces of data exceeds a predetermined number. For each of the divided pieces of data thus obtained a hash value is calculated and all the hash values are output.
