Embodiment

[0020] The method for fast fingerprint data query and comparison using multi-dimensional technology in this embodiment overcomes the defects in existing fingerprint data processing methods, which mainly includes three aspects: storing multi-dimensional fingerprint data, retrieving multi-dimensional fingerprint data, and Verify multidimensional fingerprint data. This method adopts a multi-dimensional fingerprint data storage, query and verification method, which reduces the data volume to 1% and increases the data retrieval speed by nearly a thousand times, which can solve the problem of system waiting when large batches of fingerprint data are retrieved. Longer questions.

[0021] In the fingerprint data query and comparison method described in this embodiment, the storage of multi-dimensional fingerprint data refers to the use of binary codes to store fingerprint data; as attached figure 1 As shown, if the pixel point of each grain in the fingerprint image is 1, and the blan...

Abstract

The invention discloses a method for quickly searching and comparing fingerprint data by using a multidimensional technology, and relates to the fingerprint verification technology. A fingerprint data storage, query and verification method in a multidimensional way is adopted, which mainly comprises three aspects: storing multidimensional fingerprint data, searching the multidimensional fingerprint data, and verifying the multidimensional fingerprint data. According to the method for quickly searching and comparing the fingerprint data by using the multidimensional technology provided by the invention, the fingerprint data volume can be reduced, and the storage capacity and network transmission speed can be reduced; the index way is more flexible, the index efficiency is higher, and the result is more precise; the verification speed is substantially improved and the verification result is more accurate, so that the retrieval work of large-scale fingerprint data can be greatly optimized.

Description

technical field [0001] The invention relates to fingerprint verification technology, in particular to a method for quickly querying and comparing fingerprint data using multidimensional technology. Background technique [0002] With the rapid development of Internet technology, traditional ID / key verification methods have been difficult to protect the privacy of users. Therefore, driven by many emerging security authentication models, the number of related products that use fingerprints as a verification method has gradually increased, and the number of users using this verification method has also begun to increase significantly. [0003] Among these verification and authentication tools, some use local storage to store / verify the user's fingerprint data, but a large part need to use network storage to centrally manage the user's fingerprint data, such as: police personal information database Wait. In this part of the database that adopts centralized management, the bigge...
