The speed of procedures became necessities during recent years; therefore using computers turn out to be the most important factors to increase the speed of implementation especially in security aspect such as recognition of people. There are a lot of ways to recognize the people face recognition is one of them. In this paper, the details of the face have been taken as blocks and Discrete Cosine Transform (DCT) is used, applied on face image's blocks. Then without doing inverse DCT Principal Component Analysis (PCA) is applied directly for dimensionality reduction this makes the system very fast.
