The original master key can be acquired in a number of different ways, including being generated by the device or by another device. A one-way, progressive series of keys are derived from the master key such that only images or data of a same session can be authenticated or decrypted for viewing, export or manipulation of the decrypted image/data. In order to decrypt images or data of a previous session on the device, the master key must be imported to the device, such as by, but not limited to, taking a picture of a representation of the key and interpreting the image to reacquire the master key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protecting digital data such as images on a device with image acquisition capabilities","description":"Digital data, such as images on a digital camera, is typically protected (e.g., encrypted and/or authenticated) based on a master key stored off the device.
