Identity authentication system and method based on browser fingerprints

Abstract

The invention discloses an identity authentication system based on browser fingerprints, and relates to the field of computer network security. The system comprises a user login selection module, a new user registration module, a browser fingerprint information collection module, a user fingerprint database, a browser fingerprint identification module and a secondary verification module, the system collects browser fingerprint information when a user logs in and stores the browser fingerprint information in a user fingerprint database, identity authentication can still be carried out under thecondition that browser fingerprint attributes change through a fingerprint recognition algorithm based on an incremental clustering algorithm, and the database is updated according to a result. In addition, a clustering center mechanism for updating fingerprint data when the system is idle and a secondary verification mechanism after identification failure are introduced, so that the reliabilityand effectiveness of identity authentication are further improved.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to an identity authentication system and method based on browser fingerprints. Background technique [0002] Identity authentication (Identity authentication) means that the system completes the confirmation of the identity of the logged-in user, especially the user with a security threat, through certain means, and then supervises its corresponding traffic behavior. In the new era, the network technology revolution is accelerating. The development of the Internet and the advancement of mobile technology have brought about a booming diversity of devices, spawned new technologies such as big data and the Internet of Things, and promoted a booming consumer electronics market. It has also created a solid user base for the digital economy. But at the same time, the dark side of the Internet has also emerged. Internet security incidents occur frequently worldwide, and the number...

Problems solved by technology

More mature browser fingerprint technology, such as Canvas fingerprint, is equivalent to a powerful drawing board, which requires the browser to render different images according to a set of fixed instructions based on the properties of the device, mainly based on hardware, but there are two main types: There are two problems. One is that there will be different browsers with the same Canvas fingerprint, and for a certain browser fingerprint, if some attributes are changed, the fingerprint will change, and the system will consider it a new fingerprint.
