ABSTRACT:
In one embodiment of this invention, a computer system performs a method for securely sharing applications installed by unprivileged users. The method involves the computer system receiving a user associated command from a user of the computer system. A previous application installation included installing an application manifest and application data objects in a shared repository and installing a user manifest and user configuration data objects in a private repository for an initial installing user. The computer system verifies that a digital signature of the application manifest corresponds to a public key of a user manifest for the associated user. The computer system verifies that an application identifier of the application manifest matches an application identifier of the user manifest. The computer system verifies that the data objects belong to the software application by comparing the application data objects to one or more data object identifiers in the application manifest.
