I thought it was a hoax but here is the link to the patent application:
United States Patent Application 20110282838
Kind Code A1
Accapadi; Jos M. ; et al. November 17, 2011
AGING FILE SYSTEM
A method, programmed medium and system are provided for a file system that provides for the aging of information and files stored thereon. Digital data stored on the aging file systems ages appropriately as would normal paper or photographs without the need for an external application. The aging file system uses a number of parameters depending on what type of digital data are stored. For example, parameters like ambient temperature, rate of aging, simulated type of paper or photo paper are selected and may be input to a filing system at configuration time. The aging file system also creates and stores digital authentication certificates to provide a unique certificate number based on the aged digital information.
