Worldline holography states that within the framework of the worldlineapproach to quantum field theory, sources of a quantum field theory overMink$_4$ naturally form a field theory over AdS$_5$ {\sl to all orders} in theelementary fields and in the sources of arbitrary spin. (Such correspondencesare also available for other pairs of spacetimes, not onlyMink$_4\leftrightarrow\mathrm{AdS}_5$.) Schwinger's proper time of theworldline formalism is automatically grouped with the physical four spacetimedimensions into an AdS$_5$ geometry. We show that the worldline holographiceffective action in general and the proper-time profiles of the sources inparticular solve a renormalisation group equation and, reversely, can bedefined as solution to the latter. This fact also ensures regulatorindependence.
