Abstract

See full text

Systems, methods, and devices are directed towards identifying a web browser by targeting a document parser component in a layout engine of a web browser. Malformed HTML may be provided to a client device having the web browser. Based on how the layout engine responds to the received malformed HTML, a fingerprint can be generated classifying/identifying a class, type, and other features of the web browser/layout engine. Other fingerprinting techniques may be combined with this malformed HTML approach to improve an accuracy of web browser identification, or to be used to detect/counter user-agent spoofing. Identification of the web browser/layout engine may then be used, among other things, to provide web content that is formatted to be useable by the receiving client device.
