The number of statistical-reference amended record fingerprint image, when the number with reference to amended record fingerprint image is more than preset value, history is mended Record fingerprint image is defined as legal amended record fingerprint image.

7. the detection method of amended record fingerprint legitimacy as claimed in claim 6, it is characterised in that the first fingerprint image of the judgement Also include after the step of whether the first amended record fingerprint image of picture is matched with history amended record fingerprint image：

When the first amended record fingerprint image is mismatched with history amended record fingerprint image, the first amended record fingerprint image is added to default Fingerprint template, obtain new history amended record fingerprint image.

8. the detection method of amended record fingerprint legitimacy as claimed in claim 6, it is characterised in that described when with reference to amended record fingerprint When the number of image is more than preset value, include the step of history amended record fingerprint image is defined as legal amended record fingerprint image：

When the number with reference to amended record fingerprint image is more than preset value, the first fingerprint feature point with reference to amended record fingerprint image is calculated With the distance value of the second fingerprint feature point of registered fingerprint module；

Whether judging distance value is less than predeterminable range value；

When the distance value is less than predeterminable range value, history amended record fingerprint image is defined as into legal amended record fingerprint image；

When the distance value is more than predeterminable range value, history amended record fingerprint image is defined as into illegal amended record fingerprint image.

9. the detection method of amended record fingerprint legitimacy as claimed in claim 6, it is characterised in that the amended record fingerprint legitimacy Detection method also include：

When the first matching degree of the first fingerprint image and registered fingerprint template is less than the first fingerprint matching value, the first fingerprint is determined Image is illegal fingerprint image；

According to the corresponding fingerprint characteristic type of history amended record fingerprint image, judge in illegal fingerprint image with the presence or absence of mending with history The amended record fingerprint image of record fingerprint image matching；

10. the detection method of the amended record fingerprint legitimacy as described in any one of claim 6-9, it is characterised in that described when adopting First fingerprint image of collection is more than the first fingerprint matching value with the first matching degree of registered fingerprint template in default fingerprint template When, also include before determining the step of the first fingerprint image is legal fingerprint image：

When getting the second fingerprint image of user's typing after registered fingerprint template is set up first, by the second fingerprint image and note Volume fingerprint template carries out fingerprint matching, obtains corresponding second matching degree；

If the second matching degree is more than the second fingerprint matching value, obtains from the second fingerprint image and occur simultaneously it with registered fingerprint template The second outer amended record fingerprint image, and using the second amended record fingerprint image as the history amended record fingerprint associated with registered fingerprint template Image.
