Android Browser Fingerprinting Identification Method Based on Bidirectional Recurrent Neural Network
-
摘要: 2010年浏览器指纹的概念被提出用于识别用户身份,目前这项技术已趋于成熟并被广泛应用在一些流行的商业网站进行广告投放.然而传统的指纹技术在追踪用户方面问题颇多,无论系统升级、浏览器更新还是篡改程序伪造导致的指纹特征值改变,都会使浏览器指纹发生变化.在对浏览器指纹属性进行研究的基础上,采集了安卓用户的浏览器指纹,提出了一种用于身份识别的监督学习框架RNNBF.RNNBF的鲁棒性分别体现在数据和模型方面,在数据方面构建基于指纹的数据增强技术生成增强数据集,在模型方面采用注意力机制令模型专注于具有不变性的指纹特征.在模型评估方面,RNNBF模型与单层LSTM模型和随机森林模型分别进行比较,当以F1-Score作为评估标准时,RNNBF模型的识别效果优于后两者,证明了RNNBF模型在动态链接指纹上具有卓越的性能.Abstract: Browser fingerprinting is a user identification method which has gradually matured since its concept was proposed in 2010 and is widely used in a lot of popular business websites to serve ads accurately. However, traditional fingerprinting has lots of problems in tracing users because it changes subtly no matter if the fingerprint feature value is changed due to system upgrade, browser update or tampering caused by fingerprint blocker. On the basis of research on the attributes of browser fingerprint, a great number of fingerprints from the volunteers who used Android devices are collected and supervised learning framework RNNBF for user identification is proposed. The robustness of RNNBF is reflected in the data and the model respectively. In the data aspect, the fingerprint-based data enhancement technology is used to generate the enhanced data set. In the model aspect, the attention mechanism is used to make our model focus more on the invariant fingerprint features. In terms of model evaluation, the RNNBF model is compared with the single-layer LSTM model and the random forest model. When F1-Score is used as the evaluation standard, the recognition effect of the RNNBF model is better than the latter two, which proves the excellent performance of RNNBF in dynamically linking fingerprints.
