"SF looks towards an imaginary future, while fantasy, by and large, looks towards an imaginary past."
- Frederik Pohl

Cephalic Pattern Door  
  A door that only opens for specific people.  

Lars Powderdry, weapons fashion designer, had many demands on his time and needed his space. Private space.

Lars said, "It's frankly none of your business." And stalked past the small bunch of footers who had assembled to gawk... to the up-track of Mr. Lars, Incorporated...

The doors of Mr. Lars, Incorporated, shut, tuned as they were to his own cephalic pattern. He sealed off, safe from the gaping multitude whose attention had been jazzed up by professionals. On their own the pursaps would have been reasonable about it; that is, they would have been apathetic.

From The Zap Gun, by Philip K. Dick.
Published by Galaxy Publishing in 1965

Compare to Dick's neural door lock from The Unreconstructed M (1957). The earliest reference to a biometric recognition lock is probably the phonographic lock from A Journey to the Year 2025, by Clement Fezandie, published in 1921.
