Embodiment Construction

[0050] Embodiments of the present invention will be further explained below in conjunction with the accompanying drawings:

[0051] figure 1 It is a structural diagram of the computer system for online handwriting authentication processing in the present invention; specifically, it includes the handwriting input device 1 and the flow of the online handwriting authentication method.

[0052] Handwriting input device 1 specifically comprises: handwriting input module 11, signal acquisition module 12, signal processing module 13, display module 14, wherein:

[0053] The handwriting input module 11 is that the handwriting input module provides a handwriting area to the user, and the user can write freely in the handwriting area, or write according to the shape given by the computer system; at the same time, the computer system receives the user's handwriting through the handwriting input module 11. Enter information.

[0054] The signal acquisition module 12 is that when the use...

Abstract

The invention discloses a computer-system-based online handwriting authentication method, which comprises the following steps of: writing and submitting a plurality of groups of registered handwritings through handwriting input equipment by a user, storing the two-dimensional static character pattern position information of display handwritings corresponding to the registered handwritings into a database, and finishing handwriting registration according to the conventional online handwriting authentication method; in the test of a computer system, submitting a generated identification number by the user, randomly selecting a plurality of registered handwritings from the registered handwritings submitted by a corresponding user in a registration stage, and displaying the two-dimensional static character pattern position information of the display handwritings of the selected registered handwritings to the user; and submitting a corresponding test handwriting set at a time within a specified time by the user, finishing test handwriting authentication according to the computer-system-based online handwriting authentication method, and comprehensively making a decision to finish the authentication of the user. The method has the advantages of replay attack resistance, difficulty in the attack of an imitator and active defense; and the neglected shortcomings of dependence on handwriting confidentiality and high imitation rate neglected by the conventional online handwriting authentication method are effectively overcome.

Description

Technical field: [0001] The invention relates to the technical field of biometric identity authentication, in particular to an online handwriting authentication method based on a computer system. Background technique: [0002] Online handwriting authentication uses special stylus, tablet and other handwriting input devices to collect writing signals in real time, and extract the behavioral characteristics contained in them for identity authentication. At present, the research in this area is based on traditional handwriting authentication methods. Rejean Plamondon et al pointed out in the document "Automatic signature verification and writer identification---The state of the art" (Pattern Recognition, 1989) that the design of an online handwriting authentication system needs to solve data collection, preprocessing, feature extraction, matching decision-making and performance These five categories of questions are assessed and a data flow diagram of a handwriting authenticat...
