Detailed description of the present invention
Fig. 1 is the synoptic diagram of explanation biology and smart card system system architecture.This system comprises the finger-printer reader that obtains from the fingerprint image of user's input.This finger-printer reader is connected to microcontroller by circuit.Intelligent card reading is connected to same microcontroller, and exchanges data takes place there.The all operations of described microprocessor controls biology/intelligent card reading.This microcontroller is also coordinated the data communication between finger-printer reader chipset and the intelligent card reading chipset.This system also comprises the crypto engine that is used for setting up secured communication channel between this system and the main frame that connected.
Fig. 2 show finger-printer reader of the present invention, purpose is to strengthen the Machine Design of obtaining of biological template.Described Machine Design is used to guide the user that their fingerprint is placed the appropriate location of finger-printer reader, so that the alignment error of fingerprint image can be reduced to minimum.
Fig. 3 is the process flow diagram of authentication process series that confirms card holder's identity.After biology/intelligent card reading initialization, system's indication finger-printer reader obtains fingerprint image from the card holder.Then, the finger-printer reader chipset carries out certain image pre-service to described fingerprint image, and this will improve the picture quality of the fingerprint image that is obtained.
After this, the finger-printer reader chipset will manage to utilize certain image processing techniques to extract minutia from fingerprint image.After this step, system will check whether extract enough characteristic point data from described image.If the not enough or described data of described characteristic point data comprise too many noise, then system will turn back to image acquisition step.After the characteristic point data extraction step, system will produce a kind of template, and the latter comprises characteristic point data and other specific information.Then, will send to intelligent card reading to this template, send to smart card by secured communication channel then.
In next procedure, system will wait for the response from smart card.This moment, smart card will carry out fingerprint authentication to be handled, and will be described in detail this below.
After system took out the checking result from smart card, described result was sent to microcontroller from intelligent card reading.So microcontroller is checked described checking result.If described result shows the details template and the details template matches that is stored in smartcard internal of input, then system will represent described being proved to be successful to the user.Then, system will begin access and be stored in specific information in the smart card.If described checking result shows the details template of input and the details template that is stored in smartcard internal and does not match that then system will represent described authentication failed to the user.Described result will be output to the main frame that is connected, and system will return its original state.
Turn to Fig. 4, this figure is described in detail in the proof procedure that smartcard internal is carried out.This process calculates the details template of input and is stored in matching score between the details template of smartcard internal, and the details template that is stored in smartcard internal is also referred to as " master template ".In first step, smart card receives user characteristics point data template from finger-printer reader.
In next procedure, the arrangement that smartcard processor is carried out details converts.This conversion will utilize certain statistical analysis technique to calculate the details template of input and rotation and the translation parameters between the master template.
After converting, suppose that two kinds of details templates have identical arrangement.Next procedure is will be under the condition of predetermined tolerance grade, carry out the pointwise coupling between the details template of input and master template.
After the pointwise matching process, smart card calculates the matching score of two kinds of details templates.So, this score and predetermined threshold value are compared.
Then, smart card will send back to system with described matching result by intelligent card reading.In this stage, smart card was waited for input command with a period of time free time before carrying out Any Application or any data of access.
Fig. 5 is the process flow diagram that is used for the user is registered to the program of register system.Described enrollment process begins and receives initializing signal from the main frame that is connected.
In next procedure, system is with intelligent card reading and finger-printer reader initialization.Microcontroller sends to this two devices with initializing signal.If system does not receive any error signal from these two devices, then system enters next procedure.
After initialization, system will receive the file that comprises card holder information from the main frame that is connected.This information will fit together and send to smart card with fingerprint template.
In next procedure, system requirements card holder utilizes finger-printer reader that fingerprint image (representation) is provided.If finger-printer reader is successfully to obtain signal and fingerprint image in response, then this validation process enters next procedure.
Then, the finger-printer reader chipset will be from described fingerprint image extract minutiae data, and check and whether extracted enough characteristic point data.If the not enough or described data of described characteristic point data comprise too many noise, then system will turn back to image acquisition step.At next procedure, microcontroller will produce a data template, and the latter will block holder's information and characteristic point data fits together.After successfully producing data template, system enters next procedure.
Then, system will manage to set up secured communication channel between intelligent card reading and smart card.The circuit that described template will be passed through to be connected sends to intelligent card reading.If successfully set up secured communication channel, then described template will be delivered to smart card by secured communication channel.After this, system is with the closed safe communication port, so whole enrollment process finishes.
