The invention provides an
interaction method of a multi-
service sharing self-service terminal based on a mobile application and a storage medium. The
interaction method comprises the steps that S100, a mobile terminal generates a
session key K and a
home page encryption pattern parameter; S1, a document is encrypted and is clouded together with
metadata; s200, the terminal retrieves the
ciphertext, K is obtained locally and then printed, the first page is rendered according to the S1, subsequent pages are rendered normally, and side codes are printed on the side edges of all the pages; s300, placing in a visible placing tray in a stacked manner, and only exposing side codes; s400, generating a disposable token through user near-field
authentication, positioning and stacking, transferring to an inner bin, reading a side code, checking and sorting, and then sending to a development
station to restore a
home page; and S500, outputting the positive-sequence documents and taking away the positive-sequence documents. According to the scheme, complex physical isolation is not needed, and on-site taking, whole-course peep prevention and efficient and orderly delivery are achieved.
