Abstract

The invention provides a data updating method in a comparison system, which comprises the steps of: creating an internal memory cache region in a physical internal memory, and loading updated data and information items thereof in the internal memory cache region; and looking up a corresponding current index in a local disk according to the information items, and performing an updating operation. In order to realize the data updating method in comparison system, the invention also provides a data updating device in comparison system, which comprises a creating unit used for creating the internal memory cache region in the physical internal memory; a loading unit used for loading the updated data and the information items thereof in the internal memory cache region; a searching unit used for looking up the corresponding current index in the local disk according to the information items; and an updating unit used for performing the updating operation. The data updating method in comparison system and the data updating device in comparison system have the advantages of avoiding large scale data updating delay, and comparing the updated data in real time so as to obtain a more accurate comparison result.

Description

technical field [0001] The invention relates to a comparison system, in particular to a data update method and device in the comparison system. Background technique [0002] With the advancement of technology and the needs of society, the comparison system is gradually widely used in various industries. Since the comparison system is mainly based on the support of data, most of the current comparison systems are large-scale comparison systems or even ultra-large-scale comparison systems, such as the face feature comparison system in the portrait recognition system, and the fingerprint system in the fingerprint system. Feature comparison system. The data of the comparison system is usually stored in a database, and the storage capacity can generally reach millions or even tens of millions or hundreds of millions. The size of each piece of data is generally between several KB to tens of KB, so the comparison system The total amount of data can generally reach several GB to h...
