As multithreading programs become more and more popular in the software industry, exploitation of multithreaded programs infects the software business. Board use of PCs and the appearance of the Internet have made it easy for others to abuse. Existing Thread-Objective Dynamic Birthmark (TOB) can be achieved by a thread-ignoring algorithm. SCSSB (System Call Short Sequence Birthmark), DYKIS (Dynamic Key Instruction Sequence Skin Pigmentation) and JB (Skin Pigmentation for an API based Java). The ultimate goal of the birthmark is to launch the proposed framework Fuzzy Hashing, theft detection instead of cryptographic hashing to enable similar searches. To apply this method to a simple theft-detection framework, the software is first checked by the proposed simplified birthmark method. Also show that the new framework is effective for identifying multithreaded programs in software plagiarism detection.
