This reasearch undertaken to develop facial recognition system to lie expression prediction use CBIR (Content based image retrieval) techniques. this techniques intendes technique of behavior lie acts on images JPEG compressed.System can automatically detect quickly and accurately lie acts. CBIR techniques search based on similarity visual mutual image held.Mechanisms used in CBIR is using the feature vector of the image as pointer to document image. Image feature extraction is using feature vector 2D DCT (Two-Dimentional Discrete Cosine Transform). system based on analysis and face image processing with value of the performance evaluation system retrieval precision and recal
