1 Face recognition for enhanced security. Cognitec Systems - the face recognition company

2 FaceVACS : Face Recognition Technology FaceVACS Face Recognition Technology Cognitec s patented FaceVACS technology has been developed and refined since Actually, it has been proven that FaceVACS technology is best in class. The FaceVACS technology has been made to safely recognize persons independent of variances that appear to human faces. FaceVACS technology handles pose, mimic, aging variance as well as variances coming from a new hairdo, glasses or temporary lighting changes. The independency can never be 100% based on the nature of biometrics, however algorithmic leadership, optimizing and fine tuning over a very long period caused the best of class variance independency, i.e. caused the excellent verification and identification results. Performance, i.e. the accuracy and reliability of the recognition engine, is key to the quality of face recog-nition systems. The Face Recognition Vendor Test 2002 ( initiated by the US Government has tested systems of 10 vendors (including Cognitec) in one of the largest evaluations performed so far. Results published in March 2003 have confirmed the industry-leading performance of our FaceVACS technology. Any kind of image data source is used for input, it is either a still image,a video stream or a connection to a face image database. Normalization: Based on the found face and eyes positions, the image is scaled, rotated and finally presented at fixed size. Preprocessing: Standard techniques applied like histogram equalization, intensity normalization. Face Finder Preprocessor Feature extraction The images are analyzed to determine the position and size of one or more faces. The eyes centers are located and marked. Images including eyes positions are taken as Primary Facial Data. Characteristics of the face are extracted and represented as a vector in n-dimensional space, where similarity of faces is the distance of two vectors. The vectors represent the Secondary Facial Data and are used for fast comparisons. Comparison Secondary Facial Data can be stored in a central database or on a token storage device, like a smartcard. RESULT In case the Secondary Facial Data is stored on a smartcard, only verification is possible. IDENTIFICATION MODE: The presented data is used to scan a database for most similar faces. The most similar reference data is taken as an evidence of the person's identity. VERIFICATION MODE: The presented facial data is compared to data read from the database or token. Based on the similarity threshold the identity is confirmed. 2

4 FaceVacs -Entry: Edition Access Control FaceVACS -Entry Edition Access Control FaceVACS -Entry adds face recognition to conventional access control systems. At the access point, the face of every person is captured by a video camera, the facial features are extracted and compared with the stored features. Only if they match, access is permitted. For high security areas, a combination with card terminals is possible, so that each card can only be used by its owner. Flexible communication interfaces enable easy integration into existing access control or time & attendance systems. Terminals with FaceVACS -Entry can be networked together, so that after central enrolment, the face data are distributed automatically to all terminals. In addition, visual control by security personnel is supported. All facial images taken by the terminal can be stored in a log for later visual inspection via a standard browser.. Based on the proven FaceVACS face recognition technology. Recognition time of less than a second. Easy integration into existing access control systems. Combination with card readers, keypads, and cameras of many manufacturers. Modular software architecture allows distribution of functions within the network. Visual control is possible at predefined events. Online and offline enrolment. Logging of events including facial images. Live check for high fraud protection. 4

5 FaceVacs -Entry: Edition Border Control FaceVACS -Entry Edition Border Control The capabilities of FaceVACS -Entry allow to apply the software to border control systems as well. There is a fast increasing demand from immigration and customs organizations to automate the border control process, at the same time ensuring secure checking of travel documents, and verifying the identity of the passport holder by a biometric system. The ICAO (International Civil Aviation Organization) has validated face recognition as the best suited biometric method for this type of application and is setting standards for storing and using biometrics with travel documents. FaceVACS -Entry seamlessly integrates into existing border control systems. It helps to check travelers securely and efficiently. The biometric similarity grade can be fine tuned to optimize the balance between automatic processing by the system and the delegation to border control officers for further inspection. Specifically for frequent travelers with strong biometric information stored on their travel documents or airline cards, the border crossing procedure becomes more convenient and faster..

6 FaceVacs -DBScan: Photograph matching in large databases FaceVACS -DBScan Photograph matching in large databases A common problem with databases of facial images is that the same person may have duplicate entries with different photos of the same face and under different names. FaceVACS - DBScan can help to identify these duplicates. Images from different sources can be very quickly compared to the images stored in the database, resulting in a match list of the most similar faces. Beyond the high inspection throughput of the software that runs on standard hardware, the face recognition quality is key.

7 FaceVacs -Alert: Computer-assisted video surveillance FaceVACS -Alert Computer-assisted video surveillance An important application area for automatic face recognition is the comparison of faces against data stored in a database. Like this, unwanted persons or persons listed in a database can be identified in video images. The video camera used for this purpose could be mounted hidden at the entrance of a sports stadium or in an airport. A wide-angle lens could cover a large range of view. All faces visible will be automatically detected and their facial features matched against the database. If the similarity with an entry is large enough, a quiet alarm can be issued. At a surveillance monitor, the found entries can be compared visually with the live image. All events are logged so that they can also be evaluated later.. Automatic face tracking.
