Patent attributes
Systems and methods for secure communications between mobile applications installed on a user's mobile device. In some embodiments, a first application installed on a user's mobile device transmits a message to a server, where the message is to be communicated to a second application. According to disclosed embodiments, there is no limit on the size or a type of data included in the message. The server receives the message and generates a key which is transmitted to the first application. The first application shares the key with the second application which is then transmitted to the server for authenticating the second application. Upon authenticating the second application, the server transmits the message to the second application. In some embodiments, the applications and/or the server exchanges data with goods/services providers associated with the applications.
