AB - This paper describes a method to insert and detect watermark or fingerprint to/from videos inlow-computing powered system as Android platforms. Fingerprint, which is a kind of watermark,has features such as patterns that contain information. The inserting frame numbers invideo-stream and the positions in a picture were chosen from the encrypted user ID to insert the watermarks. The used encrypt algorithm is the HIGHT algorithm which was developed forlow-computing powered systems by KISA(Korean Internet & Security Agency). Subtracting aninferred picture from the previous picture was used to extract a candidate feature. Median filteringwas used to get rid of noise and stabilize the candidate feature. New algorithm that reducescalculating steps of the median filtering was developed and applied for low-specification systems. The stabilized features were accumulated over 150 times and calculated by correlation coefficientmethod to recognize the patterns. We examined 22 videos and successfully detected the patternsfrom 21 videos. The correlation coefficient r values that we examined through this study exceededover 0.79 more than the threshold (0.7).
