Abstract: Methods and systems for secure media processing may be used to execute and certify a digital media asset by verifying that the digital media asset is authentic and has not been altered since capture. In some cases, these secure media processing techniques may be used in the mobile certification and execution application and a corresponding server system. The mobile application and the corresponding server system may automatically generate finalized documents upon receiving certified digital media and the corresponding metadata from the users. The digital media and other information from the users may be received while the user is in communication with other users. A biometric and artificial intelligent feature recognition system may be utilized to receive biometric data and verify identity. Data transferred to a secure server are accessible by various parties involved in the certification and execution process to provide transparency.

Abstract: A server system for digital media processing may receive two digital media assets and information associated with capture of the two digital media assets, such as metadata or sensor data from the respective times of capture of the two digital media assets. The server system verifies that the two digital media assets and associated information are unaltered, and that the second of the two digital media assets is captured after the first. The server system then generates a document that incorporates the two digital media assets, such as an insurance claim document.

Abstract: A light emitting diode system allows for high current end user LED matrix applications while mitigating internal damage to control circuitry that may be caused by excess current flow. In one example, multiple switches operate in parallel across an LED. When an overvoltage condition is detected in a first switch, a logic circuit determines those switches programmed to operate in parallel and causes them to conduct current. This reduces the amount of current flowing through any one switch and mitigates harm to the device. The parallel configuration of switches may be driven by a single pulse width modulated current. This allows the drive current to be divided between parallel transistors, limiting the damaging effects that can be caused by high currents flowing through the transistors.
