The invention discloses a software falsification recognition method and system.The method comprises the following steps that a corresponding first software feature character string is generated according to a received software control instruction; the first software feature character string is used as a decryption secret key to decrypt a prestored encrypted picture file, and a corresponding decrypted picture file is obtained; the decrypted picture file is loaded, and whether the decrypted picture file can be loaded normally or not is judged; if yes, software is recognized to be unfalsified; if not, the software is recognized to be falsified.The traditional mode of recognizing whether the software is falsified or not through verification character strings is replaced by the mode of recognizing the software falsification through the encrypted picture file, the recognition process does not depend on the dependent verification character strings, the recognition process is more visual, and manual comparison is not needed.Accordingly, the problems that when the traditional mode of recognizing whether the application software is falsified or not through the verification character strings is adopted, the recognition efficiency is low, and convenience is poor are effectively solved.
