Identification method based on hand vein

Abstract

The invention discloses an identification method based on hand vein. A hand vein acquisition module realizes the shooting and storage task of hand vein images, an image processing module completes the grey range consistency based on a pixel level and the size unification based on the image size and performs sharpening processing on the acquired vein images with bad quality, and a feature extraction module performs vein feature extraction on the preprocessed vein images by means of the corresponding feature extraction algorithm. The identification method directly processes the hand vein gray image, has the performances of unchanging the size and rotation, and is partially invariant to light change and affine transformation, thereby improving the identification accuracy rate, effectively shortening the identification time, and having great significance on the actual application of hand vein identification technology.

Description

technical field [0001] The invention relates to an identification method, in particular to an identification method based on the dorsal veins of the hand. Background technique [0002] With the rapid development and progress of modern society, information technology is constantly updated and improved along with its footsteps. However, the issue of identity authentication needs to be considered in people's lives. The key lies in how to accurately identify a person's identity and the confidentiality of identity. In daily life, we usually encounter identity authentication, such as computer login, handling money business in banks, and identity authentication issues commonly used in large enterprises. Therefore, a perfect and effective method of identifying identity is very useful. [0003] Traditional identification methods are mainly based on certificates, keys, passwords or PIN codes and the like. But with the trend of networking, these traditional identification mechanism...

AI Technical Summary

Problems solved by technology

However, with the trend of networking, these traditional authentication mechanisms have shown inherent drawbacks

Based on the identification method of identifiers (certificates, keys), it is easy to lose and forge, and it is not convenient to carry

The password-based identification mechanism is easy to be stolen and forgotten. Once attacked, it will bring great security risks to individuals.

There is a fundamental problem with passwords: they are most protective for businesses when they are long, complex, and changed frequently

[0013] Although there has been an upsurge of research on hand vein recognition algorithms in recent years, especially in Asia, these recognition methods are highly dependent on imaging equipment and are difficult to promote on a large scale, and the current high cost of vein collection equipment is not conducive to widespread application. social promotion
