According to some embodiments, a proxy server comprises one or more processors operable to establish communication with a secure client application of a device. The client is configured with a partition that contains data received from the proxy server within the secure application. If the client passes authentication, the server communicates preview information to the client previewing files that the server received from a business server on behalf of the client. The client requests a selected file. The server renders the selected file into a first portion and a second portion based on the immediate display capabilities of the client. The server communicates the first portion, determines that a trigger point was reached, and then communicates the second portion in response to the trigger point being reached. The client is configured to delete the first portion and the second portion in response to a completion event.

Secure data access for multi-purpose mobile devices

According to some embodiments, a method provides a designated link in a notification to an intended recipient of the message. The designated link includes a unique identifier associated with the message. Upon receiving a request to access the message, the method authenticates the request. Authentication includes verifying whether the request corresponds to the designated link provided in the notification. If the request passes authentication, the method communicates the message.

Multi-factor authentication

In methods and apparatus for non-contact testing of an electronic circuit board at least one electromagnetic emission sensing probe is disposed a short distance from a circuit board under test, the circuit board is operated while sensing electromagnetic emission from a region of the circuit board near the probe, and a time domain representation of the sensed electromagnetic emission is developed. The time domain representation of the sensed electromagnetic emission is compared to a time domain representation of electromagnetic emission of a circuit board known to be operating properly. Preferably, an array of electric field sensing probes is used to sense emissions from several regions of the circuit board simultaneously, and time domain representations of the sensed electromagnetic emissions are simultaneously developed and compared to respective time domain representations of electromagnetic emissions from circuit boards known to be operating properly.
