摘要：Cyber criminals have been using internet for sharing of large amount of illegal activities universally in anonymous manner, making the forensic investigator to difficult to trace the identity of authors. The pattern decomposition algorithm significantly reduced the size of the data sets on each pass making it more efficient to mine all frequent patterns in large data sets, but it needs the support of data sets pattern to satisfy the given requirement of minimum support. Here we proposed a new data mining algorithm called Max-miner which uses the heuristic bottom up search to identify the frequent patterns as early as possible. It increases 40% of the performance compared with the aprior and decomposition algorithm and provides the high pattern matching score and counts of the frequent item sets.
