Granted: February 9, 2017
Application Number:
20170041439
One embodiment of the present invention provides a system that facilitates the operation of a client/server application while a client is online or offline. The system operates by receiving a request from an application at a client to synchronize data with a server. In response to the request, the system places the data in a resource, wherein the resource can be a file. Next, the system sends an acknowledgement to the application. The system then determines a protocol for synchronizing…
CROSS-SITE REQUEST FORGERY DEFENSE
Granted: February 9, 2017
Application Number:
20170041144
An HTML document includes a JavaScript element that manages CSRF token use. When the HTML document is rendered, the JavaScript element asynchronously requests a CSRF token from the server. In response, the server generates a JWT using a keyed HMAC algorithm. The resulting JWT, which functions as a CSRF token, is returned to the user where it is stored in a protected variable inside the JavaScript element. The CSRF token is therefore stateless and isn't stored in a server-side repository.…
