The invention relates to an authentication system based on a second-generation ID card and the human face feature recognition, which comprises a hardware and an authentication software, wherein, the hardware comprises a camera, a host computer and an ID card reader; and the authentication software is installed in the host computer and comprises a camera shooting unit, a human face detection positioning unit, an image standardization unit, a wavelet conversion unit, a characteristic vector extraction unit and a support vector machine unit. The invention has the advantages that double identity verification based on the second-generation ID card and human face feature comparison is realized; the human face features are utilized for identity recognition without other passwords, the human face feature technology for the identity recognition is more safe, reliable and convenient; the hardware requirement is low; redundant complicated operation and substantial data storage are avoided; the comparison speed is quick; the system can be used in a majority of embedded-type equipment; and the recognition rate is high and can reach more than 90 percent under certain environments.

Optical detection device for detecting an intensity of a light beam and for detecting data transmitted by the light beam

An optical detection device for detecting an intensity of a light beam in a detection window and for detecting data transmitted by the light beam includes a first detection diode and an array of at least two second detection diodes in a detection window. In addition, provision is made for a first readout circuit connectable to the first detection diode, for reading out the first detection diode at a first readout speed to detect the data, and for a second readout circuit connectable to the second detection diodes, for reading out the second detection diodes at a second readout speed smaller than the first readout speed, so as to detect the intensity of the light beam. A fundamental consideration underlying the present invention is that although the provision of additional detection diodes in the detection window initially is associated with additional expense and a reduction of the surface area of the detection window which may effectively be utilized for data detection, these disadvantages are outweighed however, by the fact that this array of additional detection diodes in the detection window enables more effective and / or less expensive control of the alignment of the light beam transmitting the data with the detection window.
