This paper constructs the relationship framework of Applied
Mathematics to promote information application, focuses on the four important
application directions of Applied Mathematics in the information field in the
future, including network technology, image processing and pattern recognition,
data encryption and identity authentication, and data mining technology, and
obtains the results of the combination of Applied mathematics and information,
Including the use of applied mathematics tools to expand the breadth and
depth of information application, support and optimize the existing application
development, improve the value of information, support decision analysis, and
develop applied mathematics itself.
