First Claim
Patent Images
1. A computing device comprising:
- a computer-readable storage device comprising instructions that are executable by the computing device to;
receive a first secret to enable communication of data with a sender across domains via an Iframe, the receipt of the first secret indicating that the computing device is determined to be untrusted by the sender as confirmed by a user of the sender;
apply a function to the first secret and a second secret provided by the computing device;
send a result of the function to the sender from the computing device; and
receive the data from the sender via a secure communication channel formed across the domains via the Iframe using the result and the second secret.

Abstract
Communication across domains is described. In at least one implementation, a determination is made that an amount of data to be communicated via an Iframe exceeds a threshold amount. The data is divided into a plurality of portions that do not exceed the threshold amount. A plurality of messages is formed to communicate the divided data across domains.

12. A method comprising:
-
receiving a first secret by a recipient, using a computing device, to enable communication of data with a sender across domains via an Iframe, the receiving of the first secret indicating that the recipient is determined to be untrusted by the sender and is associated with a third-party site relative to the sender as confirmed by a user of the sender; applying a function by the recipient to the first secret and a second secret provided by the recipient; sending a result of the function to the sender by the recipient; receiving the data by the recipient as a plurality of messages via a secure communication channel formed across the domains via the Iframe using the result and the second secret. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
