A process for preserving chain of custody for digital evidence captured at a portable device. The portable device transmits a request to upload the digital evidence to the cloud server via an intermediary storage device. The request includes digitally signed evidence metadata with data integrity code and authentication credentials. The portable device receives a response indicating approval to upload the digital evidence to the cloud server via the intermediary storage device. The portable device transmits the digital evidence to the intermediary storage device for uploading to the cloud server, and further transmits a request for approval to delete the digital evidence from the portable device. The portable device deletes the digital evidence only after receiving a response from the cloud server indicating an approval to delete the digital evidence from the portable device.

Method and operation of a portable device and a cloud server for preserving the chain of custody for digital evidence

Methods and systems for controlling an object using a head-mounted display. One head-mounted display includes a display projector. The head-mounted display further includes an eye tracking assembly configured to monitor an eye. The head-mounted display further includes an electronic processor coupled to the display projector and the eye tracking assembly. The electronic processor is configured to determine a depth of field measurement of the eye and determine that the depth of field measurement is greater than a predetermined distance. The electronic processor is further configured to control the display projector to project a virtual line in response to determining that the depth of field measurement is greater than the predetermined distance. The virtual line is projected such that a length of the virtual line corresponds to a range of measurable depth of field measurements of the eye.
