Embodiment Construction

[0012] Below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation methods and features provided according to the present invention are described in detail as follows:

[0013] Such as figure 1 As shown, a method for identity verification through digital camera fingerprint recognition, through the lens and photoelectric converter, the captured fingerprint optical signal is converted into an identifiable electrical signal, and then compared with the pre-stored fingerprint information for comparison and analysis, And then realize fingerprint recognition; The specific implementation steps are as follows:

[0014] (1) Read fingerprint image: read the image of human fingerprint through lens and photoelectric converter, and perform image preprocessing on the original image, which includes image segmentation and image enhancement; in image segmentation, cut the read fingerprint Figure, on the basis of basically not losing useful fingerp...

Abstract

The invention relates to an identification method through the fingerprint identification of a digital camera, which comprises the following steps: (1) fingerprint image reading, namely reading an image of a human body fingerprint through a lens and a photoelectric converter, initially processing an initial image, and establishing characteristic data of the fingerprint through fingerprint identification software; (2) characteristic extraction, namely finding out data points which are named as 'nodes', namely the coordinate positions of forks, ending positions or looping positions of fingerprint lines, on the fingerprint, and the points simultaneously have more than 7 unique characteristics; (3) data storage, namely setting more than 490 generated data as a data comparison template according to the fact that the average number of the nodes on a finger is 70; and (4) comparison and identification, namely comparing extracted fingerprint data and template data, calculating the similarity degree of the extracted fingerprint data and the template data by a computer classification method, and finally obtaining the comparison result of two fingerprints. The method can perform identification and permission management on the digital camera and effectively protect user information.

Description

technical field [0001] The invention relates to a digital camera, in particular to a method for identity verification through digital camera fingerprint identification. Background technique [0002] At present, digital camera is a kind of electronic product that people often use, and precious data and memory are preserved in digital camera. While people are paying more and more attention to their personal information, people urgently need a digital camera that can perform identity authentication or authority management. [0003] However, existing digital cameras do not have the functions of authentication and rights management. As long as the digital camera is turned on, it can take pictures, record videos, transfer pictures or videos, and delete pictures or videos. Especially when the user's digital camera is lost, the information stored in the digital camera is easy to be used by others. Therefore, it is very necessary to provide a method for performing identity verific...
