A set of security templates is maintained including first and second templates. The first template specifies time and location stamp authentication for a file, and contextual security conditions that must be met before the file can be accessed. The second template specifies the time and location stamp authentication, but not the contextual security conditions. One of the first or second security templates is applied to the particular file. When the second security template is applied, a GPS-crypto device adds a time and location stamp to the particular file. The particular file is signed using a private key associated with the GPS-crypto device to generate an authentication signature based on the time and location stamp. The authentication signature is added to the particular file to allow a recipient to verify the time and location stamp of the particular file using a public key corresponding to the private key.

Systems and methods for generating and facilitating access to a personalized augmented rendering of a user to be presented in an augmented reality environment are discussed herein. The augmented rendering of a user may be personalized by the user to comprise a desired representation of the user in an augmented reality environment. When a second user is detected within the field of view of a first user, the second user may be identified and virtual content (e.g., an augmented rendering) for the second user may be obtained. The virtual content obtained may differ based on one or more subscriptions for the first user and/or permissions associated with the virtual content of the second user. The virtual content obtained may be rendered and appear superimposed over or in conjunction with a view of the second in the augmented reality environment.
