Abstract
Methods and systems are presented for authenticating web content. A request to authenticate web content is received from a user device. A first document object model (DOM) tree representing elements of the web content within a hierarchical structure is accessed. A hash value for each node of the first DOM tree is calculated based on the corresponding element of the web content represented by that node. A second DOM tree associated with a host of the web content is retrieved from a database. The second DOM tree represents predefined elements of the web content. The hash value calculated for each node of the first DOM tree is compared with a hash value associated with a corresponding node of the second DOM tree to determine whether the first DOM tree matches the second DOM tree. The web content is authenticated when the first DOM tree matches the second DOM tree.
