Aspects of the invention are directed to a method and system for end-to-end proof of display. A method for according to an embodiment includes: generating a unique identifier (UID) for a triplet including an item of digital content, an identity of a playlist that includes the item of digital content, and an identity of a player on which the item of digital content is to be rendered; generating a visual identifier based on the UID and a timecode; rendering the item of digital content on a display screen; overlaying the visual identifier on the rendered item of digital content on the display screen; capturing the visual identifier on the display screen; and extracting the UID and timecode from the captured visual identifier. A match test is performed using the extracted UID to populate a match list, which is reported to a content manager to provide end-to-end proof of display.
