Each of the templates Tmult contains a characteristic (four) indicating the other image, and a record associating the confidence value with the corresponding identification characteristic. This confidence value is updated to reflect more or less confidence in the _ identification feature. For example, because the recognition feature with a smaller confidence value finds more of the patterned object, the recognition feature has a high degree of centroid (a high confidence value). Because - literacy can be found in a number of such scanned images, or can be associated with temporary scratches on the sensor on one of the patterned objects [identification characteristics can have - low confidence values . According to the invention, when the image is scanned, the scanned identification characteristic is assigned to a characteristic with high confidence. Xuan Shi = :, not even with low confidence (10) _ miscellaneous, not to mention matching, hunting this money and the processing time required to perform the match. If the pre-employment is successfully matched with the age-recognized feature, the imaged object and the patterned object are verified. This threshold can be set using different criteria. Example ΐ When you need to check the money for a few low-level tasks on the computer age = 200807306 You must successfully match a few identification features. When the user must be authenticated to perform a high level task, more recognition characteristics must be successfully matched. Fig. 4, which is used to explain the following example, shows the fingerprint image 3GG read by the finger sensor. The fingerprint image 3GG contains identification characteristics that are used to identify the finger. Here, the identification feature includes minutiae points 301A-C and 301E_I, which include ridge endpoints and bifurcation points.

The skilled artisan will be able to clarify other definitions, including that the rectangle is rotated, converted, or oriented toward the east to match the two fingerprints and the other 'corner' where the trapezoid or other multiple (four) is used to surround the matched point. If the minutiae is failed to match but is outside the bounding box, it may not match successfully because it is not part of the image that was matched to the image. Therefore, it is not taken into account.

It is also possible to operate a single-order matcher twice to obtain similar results with different parameter settings, one loose and one tight. It will be apparent to those skilled in the art that any order and parameter settings, either alone or in combination, can be used to produce a finer granularity of confidence values, such as many matching metrics of matching errors that can be calculated per detail basis.

These incremental values represent the relative importance of each order and characteristics. However, other values and weights are also possible, including values less than zero. The process can also be repeated for multiple templates only by matching each other to the other board and assigning trusts. For example, if three templates can be used together - Figure i, ^_ Figure 2 and T - Figure 3 replace only two templates, then all confidence values can be set to zero, then all dependable group pairs are assigned by the following confidence Operation: In any order: • τ一图1 and Fig. 2 • τ一图1 and τ—Fig. 3 • Τ一图2 and 丁_图3 Generally speaking, all the models of the contact system are secret. It is advantageous to skip several pairs to save computer resources. Can,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, In the alternative embodiment, the above detail confidence adjustment technique is used in combination with the prior art 16 200807306 to form a more precise technique than the individual. Still further, in an alternative embodiment, the detail confidence adjustment technique is only applied to the slate, and the severance verification is used on the template obtained in the basin where only the single template is available. ^ Figure 7 is a flow chart of step 400 in accordance with the present gamma - implementation of the sequel - or more templates. This process begins with a step. Next, in step 410, all the detail confidence values in all templates are initialized to a value, such as 〇. Next, in step 415, the first pair of templates are matched, and in step 42, the confidence value is assigned based on the matching result and the bounding box as described above. Step 42 is based on the present invention, by sorting the details on the basis of their reliability values, sorting the details on the basis of their confidence values, deleting the details on the basis of their confidence values, or any combination of these template. In the step milk, decide if there are more detail templates to match. If there are no more, the process proceeds to its end step n n the process proceeds to step 430 where the next pair of templates is retrieved, and then proceeds to step 420. Figure 8A shows the match diagram! And the template 5 of Figure 1 of Figure 6a produced after the template of Figure 2. The template 5〇〇 contains a detail point of 52 〇 (for example, the data indicating the detail point), corresponding to one of the confidence values column 525, and the detail point and the corresponding confidence value column or record 501-510. Column 501 shows that detail point A (block 520) has a corresponding confidence value of 2 (column 525), while column 5.2 shows that thin node B (column 520) has a corresponding confidence value of 32 (block 525). The confidence values in the other columns are interpreted the same. Figure 8B shows the template 5〇〇 after it has been matched with the pepper plate corresponding to other images of the object (such as its image), so that the confidence value is adjusted. Similar components are labeled by similar numbers for all figures in the application. Figure 8B shows the corresponding confidence value of the _ a _ 441 (column 50), which is sufficient, the detail point β has a corresponding confidence value of 48 (column view, block 52 〇), and the detail point c has a corresponding confidence value (column 503) , block 520), etc., during operation, when the finger image is scaled, the record in the "candidate" template generated when the finger is scanned is matched to the record in the template 5. The scanned candidate The minutiae points are matched to the minutiae points in the template 5〇〇 to determine if there is sufficient minutiae between the successful matches. The template is considered to be a sinful finger-image-reflection detail. Matching to the details in the template 500, the green is successfully matched by several detail points above the threshold. The scanned system is verified. Usually, the record is continuously compared, and the 1 finger refers to a certain number of details with a heart value. The details are matched before being matched. Since the verification process can be performed more quickly, this is not enough to determine the details that are more likely to be located in the two templates. Furthermore, the entire template 500 is stored in the memory. - the system can store each package Many templates are in many detail points, so the memory is wasted. According to the present invention, the template leak is organized to create the template 500 of Figure 8C. The board 500" has been organized so that the detail points can be based on their confidence values from the highest So the lowest ordering. Therefore, the detail point B with the highest confidence value of 48 is ranked in the column 5〇1 + is sorted the most. The detail point A with the second highest confidence value of μ is then sorted in column 5〇2 Preferably, the template 500" is also deleted, so that the detail points having a confidence value lower than a threshold are deleted from the template 5", thereby saving money. For example, 18 807306 if the deletion threshold is 10 And the confidence value of the detail point, _胄·uf has less than 10. The preferred embodiment is wide;;::, from the table, the section and the truncation of the lowest confidence point or just the hunting by the confidence value sorting the detail to delete. It is based on the addition of factors and confidence values to attach the template table to supplement the ^ maximum coverage for the verification of the B picture (such as the first and delete threshold can be used as in the initialization of the cattle system Memory based on two: two, as it is, The threshold can be increased to limit the use of the café. The threshold can also be - system security!; = stored in the memory at a low security level, the syllabus is lower than the base. In this application, the door can also be determined by the sum of the confidence values. The sum of the heart values is at or near - the predetermined details of the letter ^=_存_ is added to the letter. When scanning, you can increase this threshold = base, not just the total sum to store two scans. If the confidence scale is the same, then the size of the cone is changed. The private bottle is the edge of the shot. The deletion calculus can be performed in accordance with the present invention. The ninth diagram is a step of verifying the fingerprint using the verification module in accordance with the present invention. The _ secret is initialized and the first step is 6 〇 ι. In step 603, the fingerprint image generation-candidate template is captured from the platform as described above and it is mapped to the next template in the template (four) library. Bu, the next "template is for the first time to be stored. Preferably, it is the detail point in the next template. Therefore, it is preferred that 'when the minutiae in the candidate template is continuously and the details in the candidate template=timed' is matched using the smallest (deleted) group minutiae point with acceptable values from the highest to the most niche value The point of detail. In step 6〇5, if the number of details of the candidate template towel is successfully matched with the next template (if the template is successfully matched), the process proceeds to step 6〇7, yielding, and successful template matching (“verification”). ) The result, and then the milk to the end of the process. Step 605 + ' If the detail threshold number fails to match, the process continues to step 609 to determine if there are more templates in the template repository for checking. If the template database has no more templates, the process proceeds to step 613, which results in a "failed module match, ("verification failed") result, and then proceeds to step 615. Step 6〇9, if If it is determined that there are more templates in the template database for checking, the process proceeds to step 611 to retrieve the lower panel, and the process then proceeds to step 603. It should be understood that although the above description corresponds to a template image of a single object, The template of the multi-patterned object can also be used in accordance with the present invention. For example, the present invention can be used to verify different fingers of a single user, or fingers of different users. Figure 1 is a verification mode of Figure 3. A block diagram of the component 220. The verification module 220 includes an input that can receive the template T1. The verification module 22 includes 20 200807306 a matcher 230 configured to match the detail template and update the confidence value as described above. The template database 225 stored in a computer readable medium receives the template 270, and matches the template in the template database 225 to the template T1. The matching zhai 230 has a confidence adjustment by the Moma. a first output, which can use the matching result to adjust the confidence value in the template. The confidence adjustment state 260 can organize the template based on the confidence value, and input the organized template back to the template bin 225. Figure 9 illustrates that the matcher 230 has its ability to generate a template match (success or failure) that is used to verify the second output of the patterned object, such as a finger. Preferably, confidence adjuster 260 is the same component discussed elsewhere as the confidence dispatcher. When a biological additional image is scanned, the single component assigns values during system initialization and adjusts these values later. In some embodiments, the single element is dependent on the processing steps (initialization or update) performed, involving a confidence adjuster or a confidence dispatcher. In other embodiments, the letter-adjustment state or the confidence dispatcher is a different component. Φ A 11A shows a matcher 230 in accordance with the invention of the present invention. Matching zarn 230 includes a first order 13^ coupled to a second order 24〇. Preferably, the first order 235 is a loose matcher that uses a wide valley limit to perform the match, and the second order is a strict matcher that uses a tighter tolerance to perform the match. Figure 11 shows a matcher 23A according to another embodiment of the present invention. The matcher 230 includes a single order 245 that matches the template in a multi-pass using a feedback loop. Preferably, the first pass can perform a loose match, and the first and subsequent pass uses a gradual match. 21 200807306 ^ Example Exercise (4), the image multiple sweep nMi θ ^ corresponds to her system is generated and stored in the template database μ 2: ° 夕 重 重 重 以 以 以 以 以 以 以 以 以 以 以 以 以 指 指 指 指 指 指 指 指 指 指 指 指 指 指Fine pointing to the ride, when it is called by r Tian; Ά 'system exists - corresponding template.

For a number of implementations, the thief template is added to the template repository. Once it is tested, it can be accessed. The system can perform certain functions, such as accessing protected files or launching specific programs. While the above discussion has focused on fingerprint sensors, it should be understood that the present invention can be used to verify other organisms such as the visual network model using identification features such as visual mode details and palm prints. The skilled artisan will appreciate that the invention can be modified in many ways. For example, a template in accordance with the present invention can be directed to different data structures that can actually store identification characteristics. In this way, the template will contain the components that correspond to the characteristics. These are the elements that can be arranged, sorted or deleted in accordance with the present invention. 22 200807306 It should be understood that the above description of the steps of the embodiments of the invention may be modified in many green forms in accordance with the invention.
