Face Attribute Convolutional Neural Network System for Data Security with Improved Crypto Biometrics

Abstract

Due to the enormous usage of the internet for transmission of data over a network, security and authenticity become major risks. Major challenges encountered in biometric system are the misuse of enrolled biometric templates stored in database server. To describe these issues various algorithms are implemented to deliver better protection to biometric traits such as physical (Face, fingerprint, Ear etc.) and behavioural (Gesture, Voice, tying etc.) by means of matching and verification process. In this work, biometric security system with fuzzy extractor and convolutional neural networks using face attribute is proposed which provides different choices for supporting cryptographic processes to the confidential data. The proposed system not only offers security but also enhances the system execution by discrepancy conservation of binary templates. Here Face Attribute Convolutional Neural Network (FACNN) is used to generate binary codes from nodal points which act as a key to encrypt and decrypt the entire data for further processing. Implementing Artificial Intelligence (AI) into the proposed system, automatically upgrades and replaces the previously stored biometric template after certain time period to reduce the risk of ageing difference while processing. Binary codes generated from face templates are used not only for cryptographic approach is also used for biometric process of enrolment and verification. Three main face data sets are taken into the evaluation to attain system performance by improving the efficiency of matching performance to verify authenticity. This system enhances the system performance by 8% matching and verification and minimizes the False Acceptance Rate (FAR), False Rejection Rate (FRR) and Equal Error Rate (EER) by 6 times and increases the data privacy through the biometric cryptosystem by 98.2% while compared to other work.

Data Security Design in Computer Application Software Development from the Perspective of Information Security Environment

“…S. Aanjanadevi et al pointed out that since the Internet is widely used to transmit data over the network, security and authenticity have become the main risks. He proposed a biometric security system based on fuzzy extractors and convolutional neural networks [3]. In order to ensure that computer software can meet the needs of users and ensure the safety of user operations, it is particularly prominent to formulate reasonable and effective safety management methods and measures.…”

Exploration of Network Security Professional Classroom in Higher Vocational Colleges in the Era of Big Data

“…Some scholars say that in the era of big data, the network security problem of colleges and universities is becoming increasingly serious. Although big data brings us a comfortable life, security issues such as personal information also pose a major threat to our life on campus [3][4]. Another experts point out that the college's safety education is facing a new situation.…”
